Can anybody confirm that Craftsman radial saws use the same arbor shaft thread size as other brands? I know my Delta 105 is the same 5/8-18LH as the DeWalt it’s replacing, but I’ve seen some online references to Craftsman saws using an Acme thread.

I ask because I want to get a planer attachment like the discontinued Wagner Saf-T-Planer, but all I can find are Craftsman ones on eBay, and I want to be sure it’ll fit. Yes, I know many people question the safety and usefulness of such devices, but for work I’m doing it looks like a good choice.

Or if anybody has a Wagner they’d like to sell…

On a related note, I’d like to find a chuck to fit the threads on the opposite shaft end… any ideas?

I own a Craftsman 10” Model 113.198110 made by Emerson. According to John Theising ,Emerson staff engineer, the nut is 5/8-12NA-2G L.H. Thread (ACME). The ones I found online are larger outside than the nut that came with my Saf T Planer ( I lost the original nut). I had to grind one down to fit in the Saf t planer head. Hope this helps.

Thanks… looks like the Craftsman planer, like the Wagner, has a straight hole with a hex recess on the back side for the nut, though whether it’s the same hex size is questionable… easy enough to deal with. The DeWalt version looks like it threads on, like the sanding disk I got with my saw.

It looks like the Craftsman planer has V-shaped blades, while the Wagner has curved hooked blades and the DeWalt has straight blades.

There is a guy selling new versions of the Wagner, but he only seems to have the 1/2” shank drill press version.

I haven’t seen any new ones advertised for the arm saw for years. I bought mine many years ago thru a company called Brookstone. I don’t use it very often since I got a planer. But I still use it on small pieces that are bowed to flatten them. I don’t trust to run the small pieces on the jointer. I have a sled I made that clamps fast to the backstop and slides left to right. A couple passes and they ‘re true.

The arbor shaft is 5/8” since you didn’t mention 12” or custom blades. Most not all are Acme thread. McMaster.com has a selection including left hand threads.

I guess I should update… I picked up a “new in box” (unused) Craftsman rotary planer on ebay for $25, and it fits my saw just fine. My arbor nut is slightly smaller than the hex recess in the planer, but close enough that I can tighten it no problem. I tried it out today and it works surprisingly well. Not a substitute for a “real” planer I’m sure, but it did a good job cleaning up and flattening out a piece of reclaimed flooring for a table I’m working on.

Bold1, Brookstone still exists, as far as I know, but their focus has changed. They used to be a great source for “hard to find tools and other fine things”, but now they just sell, well, “things”.

It’s a Delta “Deluxe 105” I recently picked up, replacing the DeWalt 7749 I had previously (actually still have, I need to get rid of it).
