Did not accomplish much today. I ordered a Rockler bearing.
Spent a few hours putting together a spreadsheet to determine what parts I need and indicate if there is a current run or parts are currently available vs unavailable.
It looks like alot of builders lean toward resin parts at the begining of thier build to lower the costs, but eventually switch to alu parts. I plan to work up another spreadsheet to compare the cost difference. Im sure the difference will be significant.
Nothing new on the Dome front...
