Nice job. Since I don't have access to this type of equipment I would of had new bosses machined, cut out the old & welded in the new. Just curious, can you post a pic of the actual cutter? Is it a single bit like on a lathe or multiple cutters like on a ream? I've only seen a larger version & that had a single cutter. They were doing about a 10" dia. bore.

We considered that but by the time we machined new bosses cut them out and welded them in it costs more than just building them up. And I am not a good enough of a welder to weld in the new bosses and keep finished bosses strait enough. so would need line boring any how.
I use single point brazed carbide tools just like on a lathe.
