I bought this radial arm saw a few months ago. It the next size up from the more common green ones, and manufactured in the mid 50’s.

I got the saw for $30 (yes – I suck), from a guy who was moving. He had the story I’ve heard a number of times: It was his dad’s saw, he never actually used it, and now it had to go. The metal stand came with it.

A few hours of cleaning, lubricating and dialing-in, and it’s become a really useful tool. I keep a 1/2” wide 8 1/2” dado set on it, and use it to cut slots and hog out material.

The switch is a small toggle on the side of the motor – not really easy to find. It stays on now and I mounted a switch on the front. I also grounded the frame in the switch box and added an outlet for convenience.

I put a plywood side-guard – I always stand to the left of the blade – just to add a bit safety. I may upgrade this to ploycarbonate or Lexan so I can see more of the blade.

I made a 4” dust collection box behind the fence, that also connect to the blade guard. It works OK, but I may try to make the intake larger to capture more dust.

So the saw was $30, and the blade was about double that price :).

Nice. That thing looks like a tank.

It is a tank – and straight as an arrow. It will be around a lot longer than me.

I think it would be wise to make the guard out of lex, and to put a slot where you have it fastened, that is necessary so that it may slide up and down and you can see just what is going on. Nice buy, best radial arms going.

Is that another RAS in the background fitted with a router?

I think that’s how I would use a radial saw if I had one. Make it a dedicated tool for cutting dados in bookcase sides and the like. Nice idea.

MrRon, yup. I took the saw off of it and put a 2 hp router on. Works great. I use it all the time.

I have 5 radial arm saws. I have not paid more than $30 for any, two are actually free. All are older DeWalts and I have the 790 as my RAS. I am going to make one into a router like you did. And now I have the way I will use the motor off that one and make a disc sander which I want to build, that looks simple enough.
Thanks for posting.

Now to finish the shaper and the DP.
