About 2 years ago I started making an outboard spider for my lathe. I had it bored , threaded, and rough sized. Never got around to cutting it down to final diameter or drilling and tapping for cross bolts.
Decided that today was the day. It rained pretty good this AM so shooting was out.
Thru hole could be bored larger if needed. It is currently around 1.3" in diameter. I used 5/8-18 Allen head bolts for the cross bolts. I used a jam nut to help hold the bolts in the lathe so I could cut the ends of each bolt flat and smooth.
Material is 6061 with .7" side walls. Kinda bulky but it was what I had on hand. I don't even want to discuss the heaps of swarf that was produced. Taking a .030 cut in Al leads to long, curly swarf. It is an absolute pain in the ass to deal with.
