Some of TBC (with TBC bushings as opposed to directly on centers and use calipers). Now, I understand there may be a run-out issue, but what about a SS, double-sided conical "nipple", insert, coupler, etc. that fits in between the upper barrel pair of TBC bushings of the lower barrel pair of TBC bushings? Assuming run-out is not an issue as we move further from the HS, wouldn't that be a way of enjoying the double-barrel turning of a mandrel with the accuracy of TBC bushings? I am really asking you expert, engineering, mathematical and just plain ol' smarter than me types . What do you think?
This insert would be no more than two 60 degree comes with their bases touching each other (of course, all one piece.).
Thanks for reading (and very likely laughing)
PS. Not looking to be laughed off of Shark Tank, just for a way for this lazy pen turner to get more done in less time without comprising quality. I make my HDPE CA bushing that way; why not SS?
