Also, I'm coming around to DPC's ideas about drill-pressing in the bearings so I can do dual bearings, right now I'm about 50/50 on that and jck57's idea about retaining washers.
Here's the "button button"
thread by cfmorrill with the correct bit size.
Here's dpc's original drill press suggestion
(I can see some nice ways to make this work and work repeatably now - and some post-processing is almost certainly going to be necessary -- I apologize for my earlier, somewhat unrealistic negativity toward the idea).
dpc also had a good insight about spacers
, which can be purchased in bulk, for cheap...and I think all the machining would remain single-sided. Have to think a bit or just try this one.
Here's jck57's retainer idea
, which is looking pretty shiny.
Ultimately I would like to take the approach dpc outlines here
- basically do a whole sheet of these things and then flip it over for processing the other side. I'm a bit concerned about losing steps and ruining whole batches of parts, tho.
dpc, jck57, Rob, thank you for all the help and ideas - means a lot to me and has really improved things overall. Also on my mission tonight is to re-read this entire thread and absorb more of the insight from everyone that bounced of my thick skull.
Also I am 90% through drawing up jck57's cradle. just dying to test that thing.
