Kips sub shaft o-ring

[Kawibunga]

OK - so I finally had some time to engineer nerd out here. The drawing below has all the info and measurements I have. Use at your own risk obviously. But my plan is to modify the groove diameter as per the drawing and give it a go! I also compare used stock measurements to Fredette's oring and to the 008 Xring. My take is use the Fredette's solution, or the Xring, or keep searching for the unicorn packing. Mine will be in the machinists hands tomorrow. If any one is interested, I'm happy to share the SolidWorks files, or as STL / STEP files, and the actual PDF of this drawing. Just PM your email and I'll fire it off............ Cheers - Robert

Kawibunga. that's a neat summary drawing. Thank you! Curious to hear any feedback from the machinist that will cut the groove.

The young fellow picked it up yesterday. Said it shouldn't be a problem. Their standard narrow cutter is 1/16" and the groove width is .080" so it shouldn't take any special tools. Will post how it all turns out. Just going cost me beer and chicken wings!

I'm going to bet that my parting tool bit (tall skinny cutoff tool steel bit for lathe use in cutting off a section from the end of a lathe turned work piece) will do nicely. I'll probably finish it off with a piece of emery cloth folded in a U-shape to deburr/polish it.
