Congreve Clock / Rolling Ball Clock Repair

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...

Bluing screws and zinc removal

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

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

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

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...

Cowells Lathe Rear Tool Post

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...

Cowells ME lathe

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...

A Parquet Floor & Inlay

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 – 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...

CNC Machine Build – TEP

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...

Making a Drag Engraver

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

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...

Synchronome Repair – making a new pallet

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

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 – Pulley Setup

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...

Gearless Clock – Pin Wheel

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 part2

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

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

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...

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 – Ignition System

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 – 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...

Building a Fire Piston

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 – 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

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 Gear Cutter!

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 – Part 1

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 :...

Boring Bar Setting Device

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...

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 – 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

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...

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 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...
