Madrone Geneva Movement Clock

I made the brass Geneva movement back in 1967 when I was an apprentice and had it screwed to the steel plate it is now mounted on…only now it has bearings in the plate and a 5 rpm motor driving it. The Geneva Movement is the the mechanism used in motion picture projectors to move the film one frame at a time. I found this wrapped up in a rag with my old precision tools and wanted to make a fitting place for it. The plan included a clock and I wanted it to be in one block of wood. I have some process shots I'll post below.
 
 The clock is a 1.5V DC Atomic clock that is set by radio frequency from Colorado. I put a rechargeable battery in it and an onboard charger so if the power goes out, it will run for 3 months by itself. The face of the clock is maple burl and the markers are shell casings. I have 38 specials in the 12,3,6, & 9 positions and 22's in the other 8 positions and the 22's have not been fired so there is no mark on the rim. I parted them on the lathe and drained the powder out. The glass is non glare type. The switch on the back controls only the motor for the movement.
 
 The Madrone case is 4" x 5 1/2" x12". The base is also Madrone wood and is 5 3/8" x 6 3/4". It is finished with wipe on Poly and three stage buffed.
 
 The bottom shot shows the cord bushing, all the cracks I had to fill and the gussets where I saved a little bit of the red Madrone bark. I was going to have it on the base all around, but too much of it fell of. I dried this block in the microwave for a whole day- 2 minutes at a time and it cracked severely. I was lucky they were all on the bottom.
 I had more shots of it on Lumberjocks but they  are WebP files and would not transfer.

Cheers, Jim

One block of wood you say? That is some serious stock removal you have achieved!
Looks awesome and can't wait to see what you find next in your "archives"!

Thank you all for the nice comments.
Hi Bruce, That one block of wood came from a log I bought in Oak Harbor , Washington. It was about 15" in diameter and around 13" long...and fresh cut. All the other Madrone logs he had were split all over. I wish the other photos  would have been able to transfer. They show how I sliced two pieces off and doweled them together so would line up perfectly after doing all the machining. Aw heck, here is the LJ project from 2015:https://www.lumberjocks.com/showcase/madrone-geneva-movement-clock.47568/

Very cool, an Atomic clock set by radio frequency. Nice work on the one block of wood cabinet, like Splinter says, that is a lot of drilling and chopping. 
Thanks , Tom. That is the most accurate clock in the house along with cell phones. If the power goes out, I never have to set it- it is always right. And changes with daylight saving time!!
