One of my pet peeves is to hear the tick tock of a clock that is out of rhythm with one complete rotation of the escape wheel. If you wanted to torture me, put me in a room with a running mechanical clock with that problem!
Anyway, many years ago I made up a batch of escape wheels for various clocks. All of them are oversize and on purpose. I like to mount them on their hub and then do the final machining to them. This negates some of the possible runout errors encountered. It still leaves possible errors from the collet and pivot construction from the factory.
Pictured, you see my set-up to true up the teeth on a mount clock escape wheel. I’m taking a 0.002” pass with a 1/16” end mill.
The clock is now put back together and the tick and tock are in perfect harmony!...Dave

Hi Junk Iron,

I bought them from eBay seller "yitamotor". Here's a page from the listing. Many, many sellers of them. I did a search for "100mm LED angle eyes" from US locations only. Do a sort for lowest price with shipping. There are ones available for around $5 with shipping but they don't have a plastic lens over the LED's.

You're gonna love the directed light on your work. I'll probably add a reflector or something on the PVC to shroud the light and focus it down better. We have a bunch of old transformers that I'm going to fiddle with on the extra light. I've got a 13.5 V transformer on the mill, will see what happens with 4 5V transformers in series. No big deal if I fry the extra HALO light, they're cheap.

Ah served my time on the prairies John. Your great people out there but your weather sucks. Only took me 25 winters in the north to realize it.

Yes you can run transformers in series as long as the total current drawn is within their rating, you can run as additive or subtractive thereby getting 18v or 9v respectively.

I haven't done anything in the shop in the last several days because mother nature is being fickle.

That is not bad for the outside temp. Or is that the temp in the shop.

That's inside the shop!
