Official Luthiers Forum!

I have a few little pieces to make....a long bar with a handle, clamps that hold the planks to the table, ect. Still have to do the wiring but this thing is going to work very nicely. The action is smooth and precise. Once the wood is bolted down to the table there is no chance of any kick back.

Right now that's just a cheap motor from a Ryobi saw (a fitting death for that saw) (need a skull and crossbone smilie to put here). There is just one part to remake if I need to use a motor with more hp.....but I think the rigidity of this saw will eliminate the need for more hp.....I don't know. We'll see.

where do you get all that aluminum ? nice work by the way - be safe.

That looks really cool!

On an unrelated note I heard aluminum is at a premium.

That is an interesting saw. What would its applications be? Relative to other already existing saws, I mean.

This saw will eliminate any need for a table saw in my shop. Granted, you guys find a lot of interesting ways to apply a table saw but, having cnc machines, my need for a table saw would only be for making rip cuts. I like my fingers and eyes and I don't like table saws. This eliminates the potential for injury that a table saw carries with it. The wood is fastened to the table prior to cutting.

It's all left over from a previous business I owned. I have about 2 tons of it.

Me thinks I would be fashioning a blade guard for the unit . It is quite good work , I would say the motor will be the first thing to crap out . Be safe

You did a beautiful job building that but it looks alot scarier than a table saw to me.

Not vacuum.....all those holes in the table are tapped....so a few simple bar clamps that screw down into the holes will hold the wood down.

Thanks. I think you'll feel differently if you see it when it's finished.

The saw is extremely rigid as it glides down the rails. The wood is fixed to the table. No kickback is possible. The only way to hurt yourself is to inadvertently run some part of your body into the blade but there is a long handle bar that I'll use to drag the saw across the wood. That's one hand. The other hand will be on a holddown switch so both hands are occupied when the saw is on.

I'm creating a shroud around the blade for safety and for dust evac.

It's just pushed down the rail by hand....via a long bar that keeps my hands 1-1/2' away from the blade.

I need to see how the dust comes off the blade before I finish the design for the shroud. Chances are, I can collect all of it if I get the shroud shaped correctly.

Wow Stuart, quite a set up, but I think it will need a lead screw to control the blade's movement, the blade as pictured will be making a climb cut, which is fine, but feed rate will be critical, a little too fast and likely to bind or stop in 8/4, 4/4 should be fine. Basically all the disadvantages of a radial arm saw. I understand the fear of a table saw, but it seems the dangers of a TS could be better addressed with proper blade guards, featherboards and such. Even best, a power feed, so how about a trade? I have a Maggi Steff power feed left over from an old business http://www.wmdusa.com/m2034.html , these things are great, heavy adjustable, big metal gears, 4 independently sprung wheels. It is 3 phase though. I would like to make a duplicarver, but not on a pivot, with a full x y z axis like a cnc, if you have parts that I could use, I would be into a trade, though shipping would likely make it expensive.

Very cool looking tool, from your other posts, I know you are a sharp tack, so you know the pros and cons of this device. Enjoy and be safe.
Rob

You just re-invented the radial arm saw.

Except shorter and with an aluminum bed!

Yeah? Find me a radial arm saw that accurately rips pieces 52" in length. I had a hard time finding anything that fit that bill. Had to make it.

To do a conventional cut you simply start the cut from the left and cut to the right. I just snapped the photo from that angle. Although one could cut from either side, I doubt I'll even TRY to do climbing cuts on this. Nice catch!

That's gonna be one big guitar !

I would think that the motor should be fixed and that the material would be moved through the blade. This is ok for a short cross cut but trying to ripe by moving the saw is an accident waiting to happen. You`ll not be able to hold that motor back if it decides to walk.

By the way I have no problem riping wood 8 ft in length on a radial arm saw.

Stay safe!

Nice workmanship!

Blade looks a bit tiny for the mechanism. Have you thought about making aluminum guitars???? A 16" blade would look a bit more gnarly on this beast.
Does it have that (protect us from ourselves) weeny brake?

I'm amazed at what people create on this forum.

Cool, I like it. Where did the rails and linear bearings come from? I've bought from VXB Bearing, but always looking for new suppliers.

Bob

Your workmanship is amazing.

With that said, there's a reason most people don't design power saws in their garage. Maybe you aren't most people. Maybe you have a background in engineering power tools. Maybe you have a background in engineering safety features to make sure power tools don't cut your arm off. But if you were like most people, and didn't have that kind of a background, I would say you're completely out of your mind. The price of a mistake or an unanticipated design weakness is high.

Well Zlurgh

Stationary work piece and moving blade.

Principle of band saw mills.

Only difference is the moving blade is mechanized to control its feed rate. instead of "along handled bar to drag the saw" Now thats the part that me find kinda needs some repenting (you know Fr. verb ponce ~ to think) You may wanna rethink that dragging part. Never seen a manual feed band saw mill. must be some reason.

Ya I read them words about the hold down switch which is a really good idea. However and never the less...whats it gonna take a dude with your skill set to mechanize driving the head...a beer, a quick sketch and a few hrs of shop time.

Other than that it sure be a nice shinny looking thing you be building.

Sorta reminds me of what W.C.Fields said about women. "Nice to look at but I wouldn't wanna own one."

Both the bearings and rails came through McMaster-Carr. The bearings are plain, frelon lined. I made the pillow blocks. The rails are precision 6061 annodized aluminum. They only come round so I had to make a flat side and drill and tap holes in them to mount them.

Stuart that makes my home-made jigs and tools look very primitive indeed . Let's know how the finished product performs.
