Welll......we're getting there but I guess a house never gets done! ;)
Yes, have a few new machines that makes part production easier - right now much focus on making bezels/inserts and...

It gets me out of manually milling 80 teeth/bezel! ;)

Thank you for trusting me with this lovely piece-the pictures does not do the dial and hands justice-they are absolutely mint!

I have been lapping some Speedmaster MkII cases for friends and when a watch from "my" year, 1970, was for sale localy I could not resist any more!

The watch when I got it:

Got a nice Tissot Navigator on my bench that had been badly polished and the owner wanted it restored to its former glory.

As the case had been badly abused som corners etc are not perfect as I...

No - I have to much junk in front of my lathes gearbox so I took a shortcut and got me a 30:1 set from Conrad! ;)

-Yes and No! :wink-new:

I need some more practice on cases with crown guards and perhaps a new jig to get the width of the chamfer perfect!

This evenings work - an old Heuer case!

Ask away! ;)

Actually it's both! I'm an engineer but working in the finance sector for many years.
My father was a research engineer/toolmaker and I have been ”playing” with laths, mills etc...

Tnx!

The case had been polished a few times and "refinished" by hand - so the corner where quite round and welding would have been necesary to get corners fixed.
The owner decided this was good...

I'm in the process of building a new machine that (in theory) should produce perfect straight graining - if it works I'll be happy to give your Exp II bezel a "touch up"! ;)

My guess is too much speed!

I’ve had similar results (bead blasting effects) when using paper of low quality - the abrasive material comes lose and "rolls" over the surface creating the bead...

Actually I think it’s hard to mess up with the correct mop!

Here is a picture of the type I usually use (Shown with a case ready to be brushed) - a simple jig for the bracelet and the brushing...

It looks like its ordinary paper with tape added on the back side for strength!

For you bracelet - why not just mask the middle and then brush the bracelet using a abrasive mop disc?

New discs with 120 to 600 grit has finally arrived - so will try to lapp some more cases soon!

Here is a Heuer case that was quite messed up from the start - I had to remove some dents.

Thanks!

My lathe can take a disc of maximum 240mm and I wanted 300mm to get the "scratches" as straight as possible.
I also use the lathe to make parts almost on a daily basis => I wanted a...

You can find my (try) to explain the procedure in post #15

Will post a film as soon as I get everything up and running as I want! ( have a 0.1mm "wobble" in my discs that I have to fix in some...

I had a bunch of O-rings in my workshop - "supply and demand"! ;)

It gets a bit stretched just at start up (~1s) but after that it's not a problem and i actually think it helps to put less strain...

Thanks all!

I've done some minor modifications to the setup with a "help wheel" to make the disc more stable and flex less .
I have also ordered new sandingdiscs with 120, 240 & 320 grain...

New wheels for the transmission made.

Thanks all - have made some new parts for the belt drive - will post pictures when I have them fitted!

Right now I'm thinking about a sutible setup for the table so that the hight can be adjusted....

Yes - the case is rotated and has contact the whole 360deg!

If you look at the STS video (40s -> ) you can see how it's done!
