I find DWO alignment to be overly time consuming and sometimes frustrating.
I had been thinking about how to speed up the process with a 3d printed tool until Bonesey mentioned something I hadn't considered. Because there are 31 dates on the wheel, they are not spaced such that you can make four windows at 3,6,9, and 12. So I worked it out using a little trig.
I made this prototype "dial" that should aid in the centering process... Here it is overlayed on a genuine 3035 date wheel:
It has five windows cut out around the dial, and three slots intended for manual alignment. The two small holes are meant for replacement dial feet that you just slide in from above and glue in place. These are located for an ETA 2824/2836.
I still need to test it to see how well it works, but things look promising: the 3035 dates seem to fit properly, as expected. Bonesey is planning to include something like it as part of his 3d printed tools suite: http://www.replica-w...ad.php?t=164231
Any comments or ideas about how to improve the tool are appreciated.
