Here I show how the telescopic arbors will work for the three sandwich gears. https://youtu.be/hC-ScFUV3_E

The wheels were cut in part 1 and in this video, I cut the wheel collets for each of the wheels   https://youtu.be/DoYrFOSyXoE

In this video, I make the wheels for the orrery using the X3 milling machine and the CNC converted 4" Vertex rotary table.   https://www.youtube.com/watch?v=jVBC2kJxF0A&feature=youtu.be    

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...

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...

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...

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...

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...

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...

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...

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...

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...

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...

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...

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...

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...

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...

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...

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...

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...

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...

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....

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...

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...
