Agenda
Notes
- CDC Front Disc
- Section B-B, what is the small step? Small step to engage the inner hub.
- What will hold the inner tube to the end plates? Without the gas plenum, there is 3/8" on radius and after the polycarbonate, at least that much.
- OPEN How thick is ring on which inner tube is glued?
- Threaded inserts? These are for screwing in the gas plenum. Used in conjunction with the above mentioned groove to position plenum.
- Holes Sizes
- Crimp pin to plastic insert - CMU will think about the fit.
- Plastic inserts are all the same, make go 0.1" past the feed-thru.(Looks like 1.2).
- Gary wants a slip interference fit. line-to-line fit.
- Plastic Insert
- Want the counter-bored shoulder.
- Donuts and feed through both have glue port and vent.
- Feed through groove moved from 0.19 to 0.25" from tip on both Noryl and Al.
- Depth of drilled holes changes (Noryl is 0.56", AL is 0.7").
- Material for injection molding, HallB used glass-filled Noryl, What did Hall A use, does Eugene know?
- Get Mac-Master Carr part & grade for Noryl for donuts and feed thrus.
Questions/notes on the end plates
- Back disc (without isometric view)
- Point 5: counter-bore for stereo layers, why so large diameter (.578), while diameter of feed trough is .500?
- Section B-B: why is the groove so deep (0.080 = 1/3 of the plate thickness)
- What about the inner gas shell?
- Is there a label foreseen to mark the start of each layer?
