Finishing sander for rounding over the corners for the risers
I have all the other belt sanders for shaping.

That air sander kenny will use MORE than all the air from the compressor and gets cold in the hand.
I have die grinders, saws, belt sander, all air, loud too :thumbsup:

So I want a narrow belt sander for shaping risers, like 1 or 2" wide belt????
Are you thinking of something like a 1"x30" belt grinder? If you take the table and platen off you get a slack belt to work with. I use one like this for sharpening knives.

$50.00 would be a good price to try one out.
Roy I have a good bench grinder with some parts (both rollers) I could make this mor simple.

Speed. I took the table and platen
Off . I still wish it had more room
And went slower
Post by: Mad Max on January 27, 2021, 08:31:58 PM
Is that to fast? does it burn the wood sometimes?
Post by: OldRawhide42 on January 27, 2021, 09:33:24 PM
New belt. But I think I would have
More control if it went slower .

Yup that's what I would do.

Sanding belt speed: 1900 -3200 FPM Is what it said for the low speed.
Is that to fast? does it burn the wood sometimes?
My observation is that the finer the grit the more likely to burn.

I also have a 2 x 30 Sorby Proedge which is a really good versatile machine, but mostly for sharpening stuff.
I shape risers on an edge sander and a drill press that I set up with sanding drums.
But I was thinking about getting a 2 x 72" belt sander, like knife makers use, to use on anything/everything. There's a tool place not too far from me that sells one that caught my eye. A Shop Fox W1843. It has a 1 hp motor, and a long 5/8" shaft off the opposite side of the motor that could be used for a sanding drum and/or disk, grinding or sharpening wheel, etc. They want $596 but I think I'd get a lot of use out of it. The whole sanding belt side can pivot from vertical to horizontal, platten can be removed, sand on the belt or the wheel. I don't know. Still kicking it around.

I had one of those skinny Harbor Freight sanders -- worst waste of money I ever spent. Lasted about 2 minutes before self destructing. I returned the pieces and got my money back. I would like to try a *real* brand one though...

It gotta be 20 years old and still going strong.
The belt can be replaced in about 2 minutes.
I use it on every bow I make.
It's in the background, only picture I have of it.

X2 for the 2X72 belt grinder. The belts are cheap and there are a thousand different home-brews for making the machines. I can use this one upright or in the position in the picture and the platens can be removed or repositioned.

I use a Makita 9031 1"x21" sander. It is the best tool in my shop, take the patton off and it is great for profiling risers or rounding the limb edges. Kinda pricey on Amazon $229 but well worth it. 80 grit works best for me .You won't be dissatisfied

There are so many Knife makers out there they drove the price up.

Sure, blame the knife makers...

That frame looks kind of light to me, but what do I know? I see that he is in my neck of the woods, I will have to have a look through on his site.
I have looked at building my own 2x72 and the biggest cost by far is the motor and vfd if you want variable speed. The frame can be done many ways but there is no cheap way to get a vfd and motor, unfortunately.

I bought a 2hp TEFC Baldor on C-list for $60. You don't need a $300. speed controller for one of these. Just put a pulley on the motor that corresponds to the required speed. Simple and cheap.
Yup just control the speed wif different size pulleys.

I want a wider range than pulleys will give. That $60 motor never happens up here, even used furnace motors are $100+. A 2hp TEFC brand name motor would be $250+ easily.

Damn, I'm glad I already have mine built. I would be demoralized by your predicament.

Router speed control not heavy enough?

Would be for my used motor. I think VFD's are mostly useful for 3 phase, for single phase you would need to figure out how to keep the capacitors out of the loop at reduced speeds.

That one would cover the amperage, but does it reduce torque when it reduces speed? I'm not an electrical guy (I'm a mechanical engineer...), but I think that is the problem with speed controlling single phase motors.

Yeah, VFD is a 3 phase controller. It allows you to vary the speed without losing the torque.

Probably not an issue if the pressure is against the platen.
