Topic tags/keywords: question resource lathe

Had a good start on the weekend. Got the shop cleaned up a bit and decided that can last long. Started turning a bowl blank, had a good start and then it happened….. The banjo breaks. It has been brazed before. Did not break in the same place. What is the best way to fix this or do I need to break down and buy a new one? It seens I have had machine repairs one after the other this year.

I would think that any attempt to repair it (heat) would further weaken it. Looks like it’s time to buy another one.

More than l;ikely that’s made from cast iron, and takersheat and a specieal rod to weld it properly. Welding it would guarantee it’ll last, so try to get the posted in the link if it’s what you need…. I have a banjo that looks exactly like yours, but it’s broken in 3 pieces…. I’ll never get it repaired as I think the design is pretty weak.. Jerry (in Tucson)

We’ve had parts similar to that break on our molders and the parts take on more stress than that part. They were always repaired successfully by brazing. Brazing is sort of an art and someone that really knows how to do it can fix all sorts of castings that you might think could not be fixed. A good welding and/or machine shop should have someone that can really do a nice job on it.

Thanks for the replies guys. It has already been repaired twice. Brazed once, not sure about the other. I am afraid it will cost as much to repair as it will to replace.

I would normally say you could get it brazed but since it has broken before in different places it looks to me like the original casting was weak to begin with. If it were mine I would replace it.
