I’m in need of the router attachment for my montgomery ward 10 inch radial arm saw. It is a simple piece that threads onto the 20K 15/32 diameter 20 tpi shaft and at the other end accepts a 1/4 inch router bit into its three jaw collet.
ToolKraft in Mass. does not carry this item. Any help with this request will be mosts appreciated.
thank you for your help,

Have you checked out eBay or craigslist in the area?

I have an older Craftsman RAS and needed a chuck for horizontal boring. I found that Jacobs Multi-craft 1/2” chuck fit the accessory shaft on my RAS. Since it worked fine on drill bits, it shoudl work OK on router bits up to 1/2” Only problem using drill bits in this fashion is that the speed of the RAS is too fast and burns the wood.

I recently bought an old Powercraft 10” Radial Arm saw to replace my burned out one.

So now I have an extra router collet from my old one.

Send me a PM if your interested.

Bayside, I was checking through Ebay earlier for RAS accesories and a guy is selling a router bit attachment. Its a Craftsman which I’m not sure if it will fit yours or not.

A while back a fellow posted that a Porter Cable collet will fit. I have a similar issue in that I have the ¼” collet and want a ½” collet to fit the 15/32” – 20 thread spindle.

He said: I removed the chuck from a porter cable router and it fits perfectly on the 20,000 rpm arbor. I will try it out tonight and let you all know how it works but this gives me the option of 1/4 or 1/2 in router bits as well as 1/2 in arbors for shaper cutters. As for the 3500rpm arbor any drill chuck will fit.

I will try to acquire a Porter Cable collet/chuck to see if it fits. My next option is to see if a machinist can identify the thread pattern and fabricate one. ($$$$)

PS – I love this saw.

I’ve never done it on my RAS, but isn’t the spindle speed too slow for using as a router? What kind of operations are you guys doing with it?
