    Greybeard,

    Well, It has been awhile. Glad your control box is working properly. It took me awhile to figure out the setup for the one I have. I have the servoed system.

    I have been designing a project since Christmas, and just about have the design portion finished.

    I have designed from scratch a wooden geared clock, except that it doesn't have any wooden gears. They are made from white corian so they will not warp, shrink, or expand. It uses sintered bronze bushings and brass shafts thru-out. It uses a very accurate strip chart recorder motor which is geared down to turn one revolution per minute. It will be resettable without manually turning the dial hands.

    Designing the gears really gave me a lot of grey hair. However they mesh perfectly now with only 0.5 mm clearance. I may post photos of it on the site when it is finished. I have several hundred hours of design time in the project and also a few hours cutting some gears.

    Well, I have tons of things to do, and my project is still calling me, and "I have hours and hours to go before I sleep". (Robert Frost - I believe.)

    Corian Shrinks and expands a LOT with changes in temperature.

    Gerry,

    I was told that Corian was very stable.

    However, I just talked to my sister who has a whole kitchen made of the stuff, and she said she had to have some sections replaced three times around her built in gas cooktop.

    Six months design in vain????

    What material is stable enough for very close tolerance in clock gears? I designed the clock gears in pairs (small pinion to driven gear) to get the close tolerances. I also had to re-work my CNC in order to get the accuracy needed in routing out the gears, and buy a new router and mount because the runout on my old router was about 0.006 inches. I also had to build me a CNC vacuum system for the corian mess. Seems like I have spent a LOT of money in vain.

    If it's indoors, and hanging on a wall, I'd think that it should be stable enough for your application. As long as it's not in direct sunlight where it could get a lot warmer. You're also probably dealing with smaller pieces, which also helps.

    Sorry for taking the thread OT.
