this weekend didn't produce very many parts. the tiller broke down - front input shaft bearing failed and put a roller into the gears which took most of my weekend. still waiting on a seal before I can complete the repair on that. but here is what I did get done. used a piece of 260 (I think that's harder than 360?) brass thick walled tube that I had left over from another project (if the tube looks bent - its because it is. it was just some scrap in my tool box). I band saw cut 2 thin sections one for a spacer and one for a washer. both were finished up on a improvised surface plate and fine sandpaper. that washer was super thin. I also ordered my self a new tool. a 7/8 oversized er-32 collet. wanted one for a while now and I think it will come in handy for finishing up the piston.
