Need a Arbor Repaired or Made

[SLK001]

Is that a square or ACME left hand thread?

Every reference I can find calls them ACME LH thread (some saws are RH thread).

It looks way too shallow to be an ACME. A square thread could be that shallow and still engage.

Hmm, perhaps? Could it just be that it is a high TPI on a larger shaft? The OD could also be worn.

All the ads for tablesaw arbors and nuts I found said ACME, though perhaps they lack the knowledge to know/care the difference.

That said, if I were making it I would just grind a tool to the profile, then use a table saw blade to set the OD, and the nut to set the depth.

Does this saw tilt to the left or right? That will tell you if it’s left thread or regular.

The main thread is definitely left-handed.

That's the kind of work that came in our door every day. Be glad to make it for you. PM me.

 

[Aukai]

There you go....

 

[ErichKeane]

I and MrWhoopee both offered to make this, Stefan, did you end up finding it somewhere? Or found someone ele to make it?

Definitely make new, could be stress cracks in the original- table saws are dangerous enough without old stressed parts to worry about
