Topic tags/keywords: router adapter radial arm saw

screws onto the motor to let you use 1/4 inch router bits on it. I found it at our local habitat store for a buck still in the package and bought it just because it was cheap and I’m cheap I didn’t have one.

Why would anyone use this instead of a router and what would they find it better to use this for?

I have a craftsman I bought in “88” and still use it a lot. It has the digital readout which is nice but uses a battery for that. Any ideas on how this could benefit me?

Hey I’m like you. For a buck I wouldn’t have passed that up either. Even knowing that I’d probably never use it, the bargain would be too good to pass up :-)

Dude hate to say it, it will be useless. I remember my saw had one when I bought it back in the 80’s. Had High hopes. I think the RPM is 3250, and the results will be underwhelming to say the least. I tried it a couple times and threw it in the tool box where it stayed till the day I gave the RAS away. Hope it works for you

I have seen some people route dados with a RAS.
You would have to rotate the motor 90 degrees to get the bit pointed down.
You could mount a pivot point in the table and lock the carriage and make a circle cutting jig.
All that said I think a RAS is to slow(RPM) to route well.
I probably would have bought it for a dollar though.

Shapers had lower RPM and they worked.
Look for router bits with 3 wings instead of 2.
You can angle to motor to create a profile that you would never do with a regular router and bit.
Feed the material SLOWER and let it cut.
For $1. you have the option to try new things at LOW LOW cost.
You might want to watch your fingers using it on saw. BE SAFE !

I had one for many years, and don’t recall using it even once. I also had a key chuck that fit that end of the RAS, it did get a little more use since you could drill holes with (horizontally). I had a sanding drum that screwed onto that stub shaft, and the saw turned too fast for that, got a lot of burn. I wound up just using my saw to saw wood.

You don’t have to put router bits in the chuck. You could put sanding disks or flaps, for example.

There was an adapter that could hook up a router and that
was beneficial

The typical RAS is too slow for router use unless you have a Sawsmith. The Sawsmith was made by Shopsmith and the motor was variable speed so router bits would spin at 15 to 18000 rpms. The Sawsmith was a multipurpose machine.I used to have one and I used it for routing with success.

Wow, lots of good info here. I enjoyed each post as it is interesting the experience each has had with this. I guess I’ll put it back in the package and more than likely end up just looking at it. Thanks for all that good comment, makes my buck well spent. larry

What you purchased is absolutely worthless. The RAS motor does not turn fast enough. Sears did this and similar things to a lot of people and is why I do not buy Craftsman products.
