Congreve Clock / Rolling Ball Clock Repair
I was looking on ebay when I came across this Congreve clock. The pictures were blurry and there was even a random black power cord dangling from the table and so I couldn`t even see if it was truly mechanical but I bid at a low price and a fantastic rolling ball...
LightWaveRF JSJS LW574 – Building a Common Anode to Common Cathode RGB LED Driver
Common Anode + R G B light strips are common and cheap on eBay and common Cathode strips ( - RGB) are difficult to find in the UK. Some 12v LED drivers will only drive common cathode LED strips. LightwaveRF JSJS LW574 is such an LED driver - thanks to Err0rC0deX for...
CNC Router MDF Build with Ball Bearing Draw Slides
I am writing this post 6 years on just due to the shear amount of views this video has on youtube. It is currently on 422,716 views as of 29.0.16 which I never expected when I posted this short 10 second clip! Despite never taking any more videos of this build as it...
Repairing an Omega Seamaster Bumper Automatic Cal.344
It is watchmaking and not clock making but I thought this was the best category for it! I have owned this Omega Seamaster for many years and sadly it stopped working about 2 years ago and has been sat in the draw ever since. It took some confidence to take it apart...

Building a CNC router dust boot / skirt / shoe
So I decided to build a CNC dust boot for my router. Turned out well, just wish I had used thinner bristles. https://youtu.be/jqDR3b1lLxg
Clock Crossing Marking Out Jig
This jig is used to mark out for crossing out clock wheels to form the 'spokes'. I had previously done this on a milling machine and it is no coincidence that the two clockmakers that saw my wheels commented on the lack of taper on the spoke. There are a variety of...
Bluing screws and zinc removal
Blued screws are a tradition in clocks and watches but finding plain steel screws is a great difficulty these days as they are all stainless or zinc plated. I've had the idea of attempting to remove the zinc and blue screws in the past but as luck would have it, I...
Wooden Clock Build
When I built my CNC machine last year I purchased DFX files from woodentimes online. I never looked at the files in detail, getting distracted as I often do and so last week I emailed David to ask if he would kindly resend the email, which he did. Over the last week I...
Building a Penny Pusher / coin pusher
It has been a while, in fact, it seems longer than a while...ages since I have last made a post! In the interest of logging all my projects as a diary of my work, I'm going to post a series of videos of a build I did this summer. I attempted to build my daughter a...
Rawyler Mill
Here are some photos of the Rawyler mill I am selling. The box of bits shows the parts that were removed from the lever conversion to graduated dials. If you have any questions then please get in contact. I've never really got a chance to use this machine but it looks...
Parslow skeleton clock – part 1 – The Pinions
It is now late January 2013 and back in November, I purchased the plans and brass for Parslows skeleton clock. After having a son born in December, I expect I can be excused in beginning this build! I've made lots of plans in my head about this build and actually I'm...
Cowells Lathe Rear Tool Post
After a bin full of scrap recently, I needed something for my confidence! I decided to make a nice rear tool post for my cowells and do a decent job of it. A kind chap on the yahoo group provided dimensions, I purchased a piece of 25mm square steel bar, slotted it and...
Eureka relief tool – making gear/clock wheel cutters
There are now a few methods of successful and less successful gear or clock wheel cutting that I've attempted and documented on this website. I have never really been happy with any of the methods show. I read about the Eureka tool in Ivan Laws Workshop series book....
Cowells ME lathe
Since looking for my first lathe back when I purchased a unimat 3, I always wanted a cowells but funds didn't allow. I've finally managed to pick one up at a great price and I'm more than pleased with it. Rigid, well made and a true precision machine; I hope this will...
Kennedy Power Hacksaw – manual, files and pictures
It seems that as these machines are getting harder to find, they are often in need of repair! This post hopes to give details on the Kennedy Saw. If you have any info or pictures of the saw please email me! I don`t often post with none project related information but...
A Parquet Floor & Inlay
I`ve recently been trying to sort out the house and have had very little time to do any projects over the last 6 months which is why it has been quiet on here. So in the interest of at least showing that I haven`t been idle, here my latest "home" project, a parquet...
3D Printer – calibrated and printing
I did my usual and rushed in places. I just can`t help it as I was dying to see some plastic being extruded. Now I have a running machine, I spent time calibrating all the axis properly. Now it is calibrated, the bed is level and everything nice and square, here are...
3D Printer – Extruding Plastic!
I am now at a stage where I can extrude plastic!! Here is the extruder built up: the extruder has some gearing which ultimately turns a hobbed bolt which grips the filament and forces it down through the nozzle: All the electronics are wired up. I`m using RAMPS 1.4...
3D Printer RepRap Prusa 2 – 3 axis built
Well in the little bits of time I pinch in the workshop, I`ve made more progress. I`ve put the 6mm ply table on 225x225mm with the belt and motor in place for the Y motion: I`ve gone for a double bearing rather than using the printed bearing holders... tough one as...
RepRap Mendel Prusa 2 – Build log – getting started
After finishing my CNC machine, I`d quite like to have a go at a 3D printer as the concept amazes me. The guys on the IRC channel are really helpful but I am pestering quite a bit as there seems to be quite a few differences with the Prusa2 over the older versions. I...
CNC Machine Build – TEP
I`ve had a couple of emails lately asking about the CNC machine on my youtube video and I believe in the background on one of my pictures. I`ve not posted much about it purely because I built it between Jan-April this year (2012) and during that period I was busy with...
Building a Small CNC Dividing Head
At Christmas I purchased a lovely Rawyler horizontal milling machine at a vary good price which should be great for gear and pinion cutting. However, with it being such a small machine, my 4" CNC Rotary Table won`t fit the bed and so I needed to make something. I`ve...
Making a Drag Engraver
When I first thought about homebrew cnc I never thought I could do fine detailed line and text work and presumed it would be only good enough for cutting mdf into rough shapes! However, I read on the net about drag engraving where the spindle doesn`t spin and you...
Glow in the Dark Keyring
This wouldn`t normally interest me but after 3-4 weeks over Christmas not really doing anything other than general maintainance on my machines, I wanted something quick and easy and saw Ralph on the forums making these. So I thought I`d have a go.... The compound is...
Building Dr Woodwards Gearless Clock – (Plans by J. Wilding)
by C.Raynerd Introduction: Back in 2003/04 at the age of 20 y/o the professor and my tutor at Uni was hugely into Patek Philippe watches. I had a bit of interest and because Patek make hand made watches they after show images of their production shops and this brought...
Synchronome Repair – making a new pallet
I`ve not made any updates in a while as I`ve been working to get my gearless clock up and on the wall! I`m just waiting for the case to be built so in this time, I have a few jobs to do, first repairing this synchronome: I`ve managed to source a pendulum bob and invar...
Woodwards Gearless Clock – Glass Face
I`m terrible at design and getting things in proportion, so for the face, I mocked it up in CAD and then made it out of a card template just to see what it looked like: (the bar code is a nice part of the design 🙂 Happy with the size and mounting positions and also...
Gearless Clock – Back Stop Modification
I don`t often divert off the plans that often but I was having real problems with back stop and I figured it was all down to its position. The plans call for the backstop to be mounted alongside the count wheel on the bridge piece as I originally built it: However the...
Woodwards Gearless Clock – Double pulley modification
It has been over 2 weeks since I updated and I can honestly say I`ve been working none stop on the clock with very little to show. The pin wheel had been damaged and some of the pins needed removing and resecuring in place which took a few evenings. I also have been...
Gearless Clock – Daisy Wheel (EDIT – first go!)
EDIT - I have decided this is not good enough and will need remaking! Well, as with last time when I hadn`t posted for a while, it isn`t not because I`ve not been working on it, just struggling! For the first time, I`ve gone ahead and made a part without actually...
Gearless Clock – Pulley Setup
I got the weight pulley system together which took a lot longer than I expected! These little things were tricky to make! They each run on a tiny bearing; Because they are only about 3mm wide, I found it really tricky to have a blind hole to a press fit. It was too...
Woodwards Gearless Clock – Initial Run!
I`ve not posted an update for a few days and the truth is, I`d made all the parts required to test the mechanism and I must have spent near 10 hours just tweeking the setup to get it to run. Finally, just as I was giving up again for the evening, I had a brain wave...
Woodwards Gearless Clock – Gated Detent & Deflector
I completed the "gated detent" earlier today. This is a critical part, it allows a single pin on the pin wheel to slide through the gate but catches and holds the next pin until the next impulse. The paddles were made from 0.02" steel shim but I couldn`t find anything...
Pin Wheel Bridge & Impulse Pawl
Here is the bridge for the pinwheel: Both wheels mounted and some pleasing filing on the arc! I also decided to make the impulse pawl and then all pendulum parts are complete. And mounted on the pendulum...
Gearless Clock – Pin Wheel Collet/Arbour
Made the pin wheel arbour tonight which also doubles up as the drive pully. There is a few issues with this related to the type of line I ultimately use. Basically, the drive wheel obtains it rotation from the falling weight, simply by the friction of the line pulling...
Gearless Clock – Pin Wheel
I next went on to make the pin wheel over the last couple of nights. Still not finished but getting there, just needs pinning. Ok here goes: Before drilling, I needed to check the drill size was ok for pinning all 60 x 1/32" pins without the need for glue. I used a...
Gearless Clock – Count Wheel with back stop.
I managed to get some snaps and make a little more progress :ddb:, although a step back at the same time :palm: Here is the wheel mounted on the clock: I then started the count wheel arbor: I didn`t get any photos of burnishing the pivots on the wheel, so here is my...
Gearless Clock – Count Wheel Pillar and Bridge
I started working on the clock again this week, didn`t get very far but here is an update on the bridge plate and pillars: Marked out the plate: And roughed to shape with a file: I then went a made a depth stop for my lathe as described by John (Bogstandard) in his...
Portable Ring Sundial – Colin Thorne
Well over a year ago, in fact probably a couple of years ago I had been shown some plans for Colin Thorne's Portable Ring Sundial while visiting a local model engineer. He had nicely put together a spreadsheet showing the calculations to generate the graph and had...
Gearless Clock – Count Wheel part2
I cut the deeper tooth and made the mounting arbour this evening. Tapping the 12BA was a little hairy and I just managed to get the distance right so that the screw heads didn`t foul the wheel mounting post :ddb: Still needs more sanding and burnishing the top of the...
Woodwards Gearless Clock – Count Wheel
I`ve spent a little while finishing this count wheel but managed it last night! The count wheel has these ratchet like teeth so that as the pendulum swings, the gathering pawl/wire slides up one of the slopes and drops behind a notch pulling the count wheel around one...
Woodwards Gearless Clock – Pendulum
Got the pendulum up and, well, swinging tonight! Hacked off a 4" (just over) length of 2" dia silver steel: Drilled it through 6.5 mm to make an oversize hole for the pendulum rod I re-drilled the top 8mm to a depth of 10mm and then I turned up some bushes out of...
Woodward’s Gearless Clock – Pendulum Suspension
I was reading about cutting the spring steel this morning and apparently you punch it out. As per Wildings instructions, I folded over a strip of brass, marked out on both the template and the spring steel: I made this punch but stupidly have rounded the edges so I`ve...
Woodwards Gearless Clock- Pendulum Clamping Bracket
I managed to make the lower pendulum clamping bracket this evening which was a really nice combination of milling and turning. The part will hang off the bracket I made earlier with the pendulum rod screwed into the bottom. I started with a rough cut 1. 1/2" length of...
Woodwards Gearless Clock – Pendulum Bracket
Got a little more done this past few hours. With the back plate now ready to hold some new parts, the first one is the pendulum bracket. I cut a couple of pieces of 1/8" brass sheet and used double sided tape to secure them together. Machined them square and started...
Woodwards Gearless Clock – Materials & Back Plate
This is the brass sheet required for the construction along with Wildings build book, some spring steel and the nylon chord. Just some proof of the validity of my story about the 2" dia steel bar coming from my original purchase of these materials. I don`t know why I...
Dr Woodwards Gearless Clock – Intro
Back in 2003/04, at the age of 20 y/o the professor and my tutor at Uni was hugely into Patek Philippe watches. I had a bit of interest and because Patek make hand made watches they after show images of their production shops and this brought out my hidden engineering...
Webster Engine – Complete
Here is the Webster engine nearly finished as it stood last week. I`ve since got it running much better, I`ve got a name plate mounted and I`ve got the petrol tank on there. Only thing missing now is the very very bottom cover with velvet lining and then a video of it...
Webster – Up and Running
After many many hours of troubleshooting, I managed to get a proper run from the engine. I just don`t have any throttle control at all. It meant to throttle adjust by adjusting the fuel/air mix on the petrol tank, I`ve seen others doing this as well but mine seems to...
Webster – First Run (Troubleshooting!)
Well the Webster finally was switched on and kicked into life. A few modifications were made; the sensor was moved against the outer frame and the crank shaft was turned down to 6mm so a clutch one way needle bearing could be used on an electric drill as a starter...
Webster Engine – One Way Ball Valve (Jan Ridders)
I went on to make the little one way ball valve as per Jan Ridders plans. I`m a little confused here. I presumed that this engine did not need a one way valve since anything coming back down the fuel intake would slam the normal valve closed. However reading a post on...
Webster – Jan Ridders Universal Vapour Carb (carburetor)
I started work on Jan Ridders vapour carb. The following pictures and comments were taken from a series of forum posts I made over a weeks or so period so if they are a little disjointed, that is why. I couldn`t find any brass tube at a decent price and when I went to...
Webster – Ignition System
I`ve got a little further with the engine, in fact I have made the magnet holder which connects to the crank. I also ordered some 3mm magnets yesterday which arrived today so I put it all together for a quick test. The video isn`t great, but I`m pleased that it is...
Webster – Valve part 2 and current assembly
I really feel for the first time like I`m getting somewhere now! I have finished the valve except the springs - need to sort those out as currently they are just 2 random springs I found just to hold it all together. And I managed to get an M10 tap (thanks again...
Webster – Valves
Finally, I have made a successful valve after many failed attempts at one piece valves. With the shaft being so narrow at 3/32" I just couldn`t get a good finish with 1" sticking out the chuck. So a huge thanks to my engineering friend Rodger, who kindly offered to...
Webster – Valve Block part 1
I`ve been dreading building the valve block, the truth is, I didn`t really understand how it worked despite hours of reading plans and posts. However, thanks to Doug in the USA who wrote a very detailed explanation of how the parts work on the plans for me. I really...
Webster – Valve Guides
Here are the valve guides that are inserted into the top and bottom block of the three piece valve block. These are very small but I was really pleased with how they turned out.
Building a Fire Piston
I was reading the "taig users" yahoo group recently where I came across a post in which someone had purchased a taig mill and lathe for the purpose of building a fire piston. Having the idea that this was some fancy engine, I quickly did a google search to find one....
Webster – Exhaust CAM
I thought I`d try something different to make my cam. My idea was that if I cut the OD to that of the "lug" of the cam and then place the blank on my CNC rotary table. The problem with this method is that it would create a slight radius upto the lug which should...
Webster -flywheel made with 24 tooth gear adapter
I drilled a new 8mm bore through the centre of the fly wheel gripping the outside of the flywheel so the hole was concentric and tapped it to hold the flywheel to the crank shaft. Flywheel complete -well nearly, just needs a good polish!. I also had to made an adapter...
Webster Flywheel – part 1
I thought I`d give the flywheel a go this weekend. To be honest, I`ve had several hours on it but I`m a bit off completion yet although hope to get it finished over the next few days. I really really liked how this turned out considering it is made from a dumbell 2kg...
Webster -Piston Compression
Firstly, I`d like to apologise for thisnext post! I`m so sad that I made a little video because I was so pleased with the piston seal! This is the longest bore I`ve done and I can safely say that turning it between centres was a great suggestion, it is true all the...
Webster Crank, Con-rod and Base
I`ve had little time over the last few weeks to spend much time on the Webster but I feel the few hours I had at the end of last week has pulled me back on track. I`ve finished the con-rod, drilled and bored true for the bearings in the main supports for the crank and...
Mardave RC Car Rear Axle Supports
My Brother-in-Law came with an interesting question, can you make me a pair of these: It is apparently one of the rear axle supports of a decent Mardave RC car his is building. There is a seller on ebay doing them for about £40 on a cnc machine. So anyway, after about...
Cutting the Webster Gear – 48 tooth 32DP
Finally, a gear has worked! I went around first with a slitting saw of smaller width than the cutter tip and to just a few thou short of the full cut. This removed a good bulk of the metal and as soon as I swapped over to the gear cutter, I could tell cutting the...
Cutting the Gear Cutter!
I`ve made a start on the gears. I`m using John Stevensons informative article on spur gear cutting, using his calculations along with Ivan Laws book - Gears and Gear Cutting from the workshop practice series. I`ve made the buttons and holder hardened them. With this...
Webster IC Engine – Frame Supports
I have managed to get a little more done on the frames / supports for the Webster Engine. The first one to attempt was the cylinder support. I bored the blind 1" cylinder neck support in the 4 jaw on the lathe. I`m becoming increasingly fond of m 4-jaw, it use to...
Webster IC Engine Part 2 – Boring Cylinder
I only had an hour one night to make my boring bar from a 0.625" silver steel bar and small piece of HSS. I also found the wood I needed to mount the cylinder (I lied, I didn`t find it, I purchased 8 foot for only 12" ) I have to admit, I was concentrating so hard on...
Webster IC Engine – Part 1
This is the first Internal Combustion engine I`ve built and I think after many weeks reading and thinking, I just about get the basic concept of how the engine runs. I have been looking to build an IC engine for a while. A friend and fellow model engineer is currently...
Webster Engine – Gear Cutting
Following are the details for the gears I will use on my webster engine. The ratio of the gears is 2:1. The plans call for the builder to purchase gears from WM Berg. I will attempt to cut my own based on the dimensions of the commercially available gears. GEAR 1 :...
Cross Slide Tooling/Mounting Plate for Boxford
In my attempt to bore between centres I have come across the issue that my Boxford does not have a T-slotted cross slide so I`m going to struggle holding the work onto the saddle/cross slide. I recently found Boxford did produce a boring table. (links broken and...
Boring Bar Setting Device
I am hoping to be doing some boring between centers on my next engine to achieve a long true bore for the cylinder. A friend and fellow model engineer helpfully showed me a picture of a device had had made to measure reach of the cutter from the boring bar. This is...
Aluminium Cylinder Puzzle by William Strijbos
I was browsing the net before Christmas and came across an engineering puzzle, the restricted nut, reasonably impressed with that but disappointed that it was actually a cheat rather than a puzzle, I started searching for potential engineering puzzles maybe even for...
10V Painted and Running
I decided to paint Brunswick green with a cream flywheel. I still need to put on the cylinder cover and then mount it on a wooden board. It is coming together slowly! httpv://www.youtube.com/watch?v=tAE83RaI8t0
10V Part 12 – First Run!
Here is the first run... a few issues but got it running after a short time tweeking it... httpv://www.youtube.com/watch?v=gTqvkCOToho
10V Part 12 – Errors and Mods
I`m not ashamed to say I made quite a few errors during the build of which I`ve learnt from all of them. Here are my errors and how I got around them or the modifications I needed to do to overcome them: First, in the video I don`t know if any of you noticed the brass...
Part 11 – Flywheel, Steam chest…
I`ve been working on this during the odd few minutes I get in my free time so no construction pictures again although most of these parts were quite straight forward. So here is everything together Steam chest mounted - ...eccentric mounting Flywheel, still needs more...
Part10 – Stuart 10V Con Rod and Cross Head
Got back on track with the 10V this week. I got to the stage where I had finished the crank and con rod. This was a real pain because the con rod had been started, the only piece that had been touched on the entire set when I purchased it second hand (strange place to...
Ratchet Wheel for Traction Engine
This is a bit of an old post but I haven`t updated anything for a while so I thought I`d put this up. Sadly no construction pictures but this was a good attempt at a ratchet wheel for the 1" Minnie Traction engine. I don`t really know why I made it, I wanted to...
Part 8 – 10V – Bearings and Crank
I`ve been making some steady progress on this engine and finally I feel I`m getting somewhere. I finished the bearings but it was hard work. My drill wondered on the first hole which made it very tough to re-centre. I managed it by bolting a small strip of steel on...
10V – first error!! Bushing cylinder cover bottom.
I had a week off due to being away with work and then when I came back had man flu and felt terrible. However, I had withdrawal symptoms from the workshop so braved a few hours down there, in which time I managed to break my Shumatech DRO, destroy a shop light, fail...
Part 7 – bottom cylinder cover
I managed to finish the more critical bottom cylinder cover today. As I mentiond in my last update, I needed a 5/32" reamer, I could have waited until the midlands show but a local friend I have recently made had one on hand to lend me so I could continue! No much to...
Part 6 – cylinder ports and top cover
I`ve still been working on this over the weekend with some progress and what I did attempt seems to have gone well. I first finished off the cylinder and also drilled the steam ports including drilling and tapping the exhaust. I must admit, I tapped the exhaust a...
Part 5 Cylinder
Well first problem this evening was of my own doing! I`ve managed to do a superb bore that I`m really pleased with and then I went and faced off the bottom but have not taken quite enough off. I don`t know how I`ve done it as I`ve checked and double checked but I`ve...
10V part 4 – Boxbed, soleplate and standard
I`ve spent two nights on this now - and things are going slow...but what is the rush I guess!! I was hoping to bolt everything down (drill and tap) and then get the cylinder machined. It has taken me 2 nights to make the jigs, drill and tap and also just face up the...
10V part 3 – boring the standard
I had advice off others on the internet that my methods looked secure but that I needed steel clamps as the brass ones were no use bending as they were. Once they were made I started boring: boring the standard: After testing the bore with my go/no-go gage the bore is...
10V – Part 2 , Maching the Standard
Well after my efforts in facing up yesterday and the comments I recieved regarding the methods I used to hold the standard, I thought I`d continue with this tonight. I did appreciate that when I bore the standard I would need to face up the top surface for the bore...
10V Part 1 – facing up and making a start.
I plucked up the courage to start machining some of my castings this evening. I seemed to have some sort of unfounded fear that I`d manage to chip or crack a casting some how, but strangely enough, it all went very well....infact, too well ! Despite reading all the...
Stuart 10V: Arrival – In the box
A good friend was willing to sell me this Stuart Engine 10V at a very good price and I`ve never worked on castings so this will be new to me! I believe he purchased it with a machine or some equipment and has never touched it, however the original buyer sadly did!! An...
Thrust bearings for the Boxford
The current state of the cross slide and compound slide: Cross slide: The gap/play in the cross slide. This closes if you pull it back but of course the play is there. The first two pictures show the lead screw of the cross slide removed, and notice the gap. The whole...
Kennedy Power Hacksaw
When I first saw one of these running I really liked it. Being in a basement workshop, I`m limited with the size of the equipment I can have down there, especially floor standing. This is an ideal size, OK, limited certainly to the size I can cut but it`ll certainly...
X2 Power Feed Controller – Complete
Finally, up and running! An X2 stepper motor power feed using a PIC controller unit to move the table, 10 speeds and programmable limits. Video to come shortly: A few pics of my veroboard built circuit - not the neatest, but it works! The ArcEuro purchased 4amp...
Single Axis Stepper Controller – first run
I first started this in Dec 2009 and put it on the shelf for the last 6 months. I finally found the time to re-write the code, programe a PIC, buy a 4.2A Stepper Driver and give it a real test run in situ. http://www.youtube.com/watch?v=w4t_3vUdKfk Next - tidy the...
