chefcook Posted August 30, 2010 Author Report Share Posted August 30, 2010 Though I appreciate Sander's efforts I'll follow the RTM path. I think it is worth a try. Link to comment Share on other sites More sharing options...
Katerchen Posted August 30, 2010 Report Share Posted August 30, 2010 I just love this place! The mad scientists that collaborate here are just amazing! LOL You nailed it! Happy to see Dr.Sander getting active again and @eunomians wait and take a look when ill upload pictures of AP parts available which i will after my root-canal treatment... I remember to have taken pics of 2-3 gen movement plates for regular AP ROOs what might be a good "start" to build/mod your RB plate and add some cote de geneve to B/R George Link to comment Share on other sites More sharing options...

subbiesrock Posted August 30, 2010 Report Share Posted August 30, 2010 What about a solid blocks of this RTM material, then machining the watch case from it? The part that is shown in the images still needs some finishing, I assume. What about a solid rectangular piece, then you machine the case in a 5-axis CNC. That would be far more doable. The only question is durability during construction, metals are predictable under Tungsten Carbide tools, not sure if this CF/epoxy mix is too brittle to be machined... Other than that, this project is crazy, you're all nuts! P.S. I's DEFINITELY be up for one, pending surface quality ) Link to comment Share on other sites More sharing options...

lololo33 Posted August 31, 2010 Report Share Posted August 31, 2010 Only thing I am concerned of when machining a case from a CF block is fiber ends sticking out of the surface. That's a main problem with such parts and a huge advantage of RTM where it is very unlikely. The carbon can be sealed with a thin coat of clear epoxy resin which would also do very well for scratch resistance. This can be hand applied, cut, buffed, polished or sprayed in light coats for a matte finish. You can also spray a coat of acrylate (crazy glue) which soaks into the cf and gives a nice scratch resistant finish. I have no interest in repping AP cases but I'll try a proof of concept with some thick pieces of carbon I have laying around. I do have a little experience with this sort of thing, this is a solid CF bezel insert for a custom maratec: Link to comment Share on other sites More sharing options...

Bike Mike Posted August 31, 2010 Report Share Posted August 31, 2010 What about tapping holes for lug screws and such? I think AP would have thread metal inserts that are encased during the manufacturing process...Carbon does not hold threads well in its purest form...it is too brittle.

lololo33 Posted September 1, 2010 Report Share Posted September 1, 2010 What material is this dial made out of? And is that an angled day/date at 4:00? Nice! Carbon fiber as well.. that dial is just a single layer thick. The watch is set up as a lefty and I swapped in an ETA 2836. I couldn't find lefty date wheels so instead I placed the date at 4:00ish position 231.43 degrees clockwise from the crown. I'm just getting it ready to deliver will take some more pics before I ship. Link to comment Share on other sites More sharing options...

chefcook Posted September 1, 2010 Author Report Share Posted September 1, 2010 A RTM mold for our purposes can be made from aluminium, so I doubt that it will be more then double the price of a single case milled out of a solid block of carbon. Downside of the RTM is the fabrication time: With home made equipment I'd have to use other epoxy resin than for industrial purpuses so that I estimate a fabrication time of two days per case (of which 99% is time for hardening the resin).

chefcook Posted September 14, 2010 Author Report Share Posted September 14, 2010 Within the next days I should receive my sec @ 12 silver themes. I'll take measurements from the case and will start designing a mold after that. Link to comment Share on other sites More sharing options...

chefcook Posted September 19, 2010 Author Report Share Posted September 19, 2010 OK - just realised that the carbon cases have slightly different crown guards. Will need to do some picture engineering as I don't have a gen to take measurements.. Link to comment Share on other sites More sharing options...
