It took me a while to figure it out. Ideally I should have had a milling machine. Or maybe forged it, but I didn't trust my heat treating skills for this as strength is critical. Also can't weld anymore so this seemed the only (but tedious) option. Notice that the round bit at the end has a stepped recess inside. This is for an endcap to fit into so I have frame in the middle.Bod":2lpyb6mj said:Thanks.
It's simple when you know how!
You had me puzzled, I was expecting vary special cutters.
