Topic tags/keywords: jig resource question trick carving tool planer miter saw router milling joining shaping

Where I live there are always radial arm saws to be gotten for a good price. after seeing the post about that shop smith thing the guy made into a mortiser I got to thinking if I bought one of these could I take the saw off and install a 3hp router. has anyone seen anything like this or have anything like this any thoughts?

I guess the trick would be finding a good way to mount the router. It’s an intriguing idea, though.

very much like that
I figure it is a manual cnc router
square, parallel, and mitered cuts could be made anywhere on the board
plus no more setting straight edges to cut dadoos and sliding dovetails
variable spaced dovetails could be accomplished and repeated with stop blocks
easy radius just lock on the slide unlock the miter and swing

the possibilities are endless
I should get a patent j/k
If I build it I’ll blog it so you guys can see

having trouble writiing a vega duplicator is coming today and every loud truck has me running to the window
Isn’t funny how you order a tool then become a six year old on Christmas eve and the ups man suddenly becomes Santa. I think I’ll offer him some cookies and milk.

I think I may be a toolaholic…Na

Jm5400,

Now I have seen routers on vertical panel saws. I have not seen too many Radial arm saw/router retrofits. There is a advantage to having the ability to having the material still and the router move. The abilitry to make make 90 degree trims is very nice.

There however is a better way to do this. The first would be to get a couple of linear bearings. I have made many custom jigs with linear bearings and you can also make a router that will make a long cut (with a long linear bearing). You can find linear bearings on ebay that are very inexpensive. Linear bearings such as THK, Thmpsions, etc are very accurate and are used in cncs so if you are making your “raidail arm router” or “panel router” these will work well. I have made many contraptions like this so if you need any advice or help I can tell you how to make these.

If you are dead set on a radial arm saw, you will likely have to make a bracket or have one machined. The way you would do this is to make a bracket that will mate into the base of your router. You will also have to have a bracket that will mount to where the saw mounts. I would recomend using aluminum. If you have the footpirnt of your router and the the dimensions of where this bracket will mount, I can help you design this.

Cheers,

Ben

I had a Ryobi 8 1/4” Radial Arm Saw that had a 1/4” router chuck on the opposite end of the mandrel. It was good for some overhead cuts and for using masonite patterns etc. There’s still a lot of these out there for sale, used or new.

Think I remember seeing Norm use a shaper head setup on his. He had the motor locked in position and you push your wood thru like on a router table. Looked scary to me…maybe Norm’s real intentions were to prove to us all that he’s got a set!

sounds like gooda and I have thought of that before. The thing is how useful would it be vs. time and money to build it. With mortising big enough peices you’d even consider using something like that for it’s always better to bring that tool to the work. But if you have the time go for it

The “Router Boss” and “Woodrat” seem to use similar principles. ($1000.00??) So the question is can their functionality be equaled using a radial arm saw foundation for less cost.

I’ve got the same saw as poopiekat does the “RA200” had it for 20+ years. I have used it as a router and it did a fine job, but I prefer it as an RAS instead of the router, that’s just MY opinion.

I swear I have seen a bracket that you can mount a router to the arm of an R.A.S. I’ll keep an eye open to see if I find one.

linear bearings sound great.
I can get a radial arm saw for about $100 if I could find one with a burnt up motor for free would be better since I don’t need that part anyway.
as for the mount bracket I was just gonna use the same one I used for my compound miter router

I’ll have to look at that wood rat

The Ryobi mentioned above was the unit I used to get some really different cuts that would be hard to achieve, especially where the router axis meets the wood at an angle other than perpendicular. With the articulated head, many cuts can be achieved that would be otherwise impossible. I got rid of mine, though, along with the BT2000 saw and just about every other Ryobi tool, because they’re pretty crappy in general. I still do love my 4 1/2” oscillating disk sander, going on 20 years and still a champ. Googling Ryobi RA200, the first few results are for a product recall.
Having used an Onsrud Pin Router in a few commercial shops, I’ll swear by the capability of having your rotating cutter ABOVE the work, rather than below for some applications, which was why I bought the Ryobi in the first place.
I think Harbor Freight has a collet adapter that screws right onto a 5/8” mandrel for converting your radial saw to a router…and does that for about $10.

When I got down to my shop I realized my last post was very irresponsible. Saftey first and it is no joke so don’t try to reproduce my compound miter router and if you do send me some money. BUT SERIOUSLY use a UL approved tape
