hologramet Posted January 19, 2016 Report Share Posted January 19, 2016 So let's do a little necro-bump. >> I'm looking at double-domed sapphires for a 116110 Noob-project. The only candidates seem to be: Candidate 1: Type : Double-Domed Diameter (Size): 30mm Thickness : 1.8mm Height: 2.6mmMaterial : Sapphire Crystal http://www.ebay.com/itm/301642988489?_trksid=p2060353.m1438.l2649&var=600504451449&ssPageName=STRK%3AMEBIDX%3AIT Candidate 2: Type : Double-Domed Diameter (Size): 29.5mm Thickness : 1.8mm Height: 2.8mmMaterial : Sapphire Crystal http://www.ebay.com/itm/301719925440?_trksid=p2060353.m1438.l2649&var=600553582169&ssPageName=STRK%3AMEBIDX%3AIT Candidate 3: Type : Double-Domed Diameter (Size):29.5mm Thickness : 1.4mm Height: 2.5mm Material : Sapphire Crystal http://www.ebay.com/itm/29-5mm-Sapphire-Crystal-Watch-Crystals-Double-Domed-Height-2-5mm-x-Thick1-4mm-/291476051243 Candidate 4++ 30mm thick: 1,5 // 30,5mm thick 1,2 // 30,5 thick 1,0 // 30,5 thick 1,3 >> Which is the most suiting one? Which gasket should I use? Any Clarks or similar gasket would help. Quote Link to comment Share on other sites More sharing options...
hologramet Posted January 25, 2016 Report Share Posted January 25, 2016 Anyone? So a "regular" crystal is 29.5 mm in the "mounting" part C. And 30.4 mm in the visible part A. I'm guessing the width of a gasket is about 0.45mm. Then we have the height E... Since the double-domed sapphires aren't available with a lip, I guess the only option is getting one that is 29.5 (C) with a thickness (D) of 1 to 2 mm. Should I use an I-formed nylon gasket or an L-formed? L-formed right? Then I can do: How high is b? Because I don't want the sapphire to be "too" recessed, neither do I want it too high? --- Please any tips? Quote Link to comment Share on other sites More sharing options...
