Can anyone give me the proper education on what set screw to use where, when and how?

I noticed a new set screw when I looked at the shopsmith 5/8" arbor. It looks like it has a brass tip!

I have a variety of set screws with a variety of lengths and different set designs. Some are flat at the securement point and some have the little teeth and the 5/8" arbor has the most unique one with the brass tip.

I have noticed in the past that the set screw will sometimes back out of the 1 1/4" saw blade arbor which I feel is dangerous and it seems like the arbor actually has some movement on the quill hub.

I was wondering what set screw people use to secure their table saw arbors to the quill hub on their Shopsmiths to prevent loosening.



How much torque do you apply when securing the set screw of the tablesaw arbors. My SPTs are secured with the set screws with teeth and I lock them in place with blue loctite but with the saw arbor coming off the quill more often than the hubs coming off of the SPTs, I can't really lock it into place with loctite.

Cheers,

The brass set screw is relatively new to the Shopsmith parts list. I had none in my equipment until very recently when the discussion came up here on the forum.

The set screws that you have pictured are serrated, flat, half dog and cupped. I think. I can not see that detail for certain.

I seldom have an arbor set screw come loose but when I do, it is discarded.

Attached is a spread sheet that I have been attempting to maintain over the last few years. I hope that it is of help. There is another, very professionally developed list complete with pictures but I can't locate it in my files.

Is one in PDF

I think it has been posted in several threads over time

Thanks so much! That PDF alone is gold.

So, I am assuming no one uses the knurled/serrated set screws on any of the headstock shafts?

I would not.

However the cupped are appropriate for the hubs.

Only a flat or half dog(brass) on the quill shaft.

P.S. Serrated are easier to find locally, but the disk sander will 'flatten' them easily(use ss tool kit and miter gauge).
