Yeah, I was gonna do that, but by the time I ordered washers from Fastenal, (a madxj.com trick) and found some black pipe at 3-1/2" or 4" I would have more in them than if I were to just hock a piece of billet alum. from work and turn them out on the lathe. I started them today and will finish in the morning. Perhaps I'll post a pic.
Thanks.
