RWG Technical Posted December 9, 2010 Report Share Posted December 9, 2010 Many times when you are making a custom build, the dial is much thicker than the original dial, and you need longer cannon/hour wheels to allow the hands to clear the dial. Buying new parts would be the easy solution, if they were available... since they are not available, the solution to the problem is to fabricate new parts. Here's an overall view of the Cannon pinion and Hour wheel from a Cortbert 616 as delivered, as you'll see further down, they are much too short for our new dial thickness... As delivered The specifications were to raise the cannon pinion and hour wheel (2 sets) high enough to clear a 1.7mm and 2.7mm dial thickness respectively. I am not going to show all the machining and fabrication steps required to make these new parts, it is a lenghty, time consuming, and demanding process, with tolerances in the +- 0.01mm. I will show the end results of my efforts, I hope you like it and find it interesting. ORIGINAL on the LEFT, NEW on the RIGHT Various views of the longer cannon and hour wheel pipe. Here are the two new sets all finished and ready to send out. Thanks for reading. Link to comment Share on other sites More sharing options...

Andei3000 Posted December 9, 2010 Report Share Posted December 9, 2010 Awesome craftmanship there Mr. The Zigmeister! I wish I had the tools to produce such unique parts. Sadly you are not showing the production, as it would be really interesting how to cut the teeth on the hour wheel? -andei Link to comment Share on other sites More sharing options...
praetor Posted December 9, 2010 Report Share Posted December 9, 2010 nice job The Zigmeister. Sometimes you need a thick dial to make the rehaut thinner looking. You just brought the perfect solution. Link to comment Share on other sites More sharing options...

RWG Technical Posted December 9, 2010 Author Report Share Posted December 9, 2010 as it would be really interesting how to cut the teeth on the hour wheel? Actually...I didn't cut new teeth on the hour wheel, I cut OFF the old pipe, fabricated a new one, and brazed the new pipe to the old hour wheel gear... How's that for craftmanship? Now I have you thinking don't I... Link to comment Share on other sites More sharing options...

How's that for craftmanship? Now I have you thinking don't I... I wouldn't call it craftmanship, that's just frightfully clever! Skipping the crucial part of reproducing the teeth makes it cheaper and the parts have to be fitting as they are the originals...

panerai153 Posted December 10, 2010 Report Share Posted December 10, 2010 Would this fix work on the 2893-2 movement to get the hands high enough to clear the dial indices on a GMT master IIc? That seems to be the biggest sticking point preventing a movement swap from a 2836-2 to a 2893-2 Beautiful work as usual . :thumbsupsmileyanim: Link to comment Share on other sites More sharing options...

Given it's a recent movement there is no need to fabricate new ones anyway.... ETA makes a large variety of lenghts and there are some that are really long, so replacement with new parts should be the solution. The biggest problem with this type of swap is always the location of the stem, it doesn't line up with the case tube and is the no-go issue and not correctable.
