Mystery Arbors

[jsburger]

Dusty, the threads shaft on a shaper arbor is thinner. Isn't it 1/2 vs 5/8 inch on a dado/molder arbor?

I don't know! Mine are all packed (prematurely) for relocation and I can't go look. Even my documentation is stuck away somewhere.

Yes, the shaper arbor is 1/2" and the dado/molder arbor is 5/8".

I have had several different kinds but never paid attention until they were side-by-side. I know I have either sold or given away ones like the longer shaft because I remember the thread sticking out before. So I guess it's not that rare.

Could one be for a grinder wheel ?

Good question!!!!

However I do not recall that they included the 'thick' washer.

The grinding wheel arbor is 5/8" but has completely different 'thick' washers. We have had this discussion before. There are arbors with and with out groves and tongue washers. There are also two different lengths for some reason. There are black ones and non black ones.
