Belt Sander for Deburring...

[cstroke]

Hey all,
Anyone have experience with these type belt sanders??
Looking for something that will get limited use, so not looking for a super expensive tool, but also don't want a harbor freight..

Yes I have worked with similar belt/disc combination sanders and I dislike them for metalwork.
A 2x72 has alot more possiblity for upgrade options, brodbeck ironworks and ameribrade come to mind but they are not cheap.

If your looking at building a 2"X 72" belt grinder here is one I built and I have the DXF file for all the cut parts. Your looking at about $550 complete.
I have built 3 with different drive motors, great tool to have.

Yes, looking to cut chamfers on aluminum square tube and not use a regular grinder, also steel etc...
I think I want one with the disc.
Thanks
Chris

I have 3 of these in the shop and they work great, and real quick to change the belts.

I also have one of the cheap Grizzly best/disc combo units for occasional use out in the machine shop and it is great for the price.

I have one of these in the main shop and mainly use the disc portion. It's a very nice unit for my purposes.

Tom - those look very nice! Great job. Sort of reminds me of one I saw Jeremy Schmidt build on Youtube a few years ago.

Chris - what size and wall thickness aluminum square tube are you wanting to chamfer? I will say that aluminum can clog up those closed coat sanding/grinding disks pretty quickly. But I expect there are some disks designed specifically for softer materials. I do mostly steel, so the regular belts and disks work fine for me.

These are the two Grizzly sanders I use the most.

David I did buy Jeremy Schmidt plans and built the grinders from those, worked out very well. I also built the optional attachments he showed so it very functional to do different projects.

I strongly agree on this, there are special belts for aluminium but they still clog up.
Another downside of belts is that some belts can introduce alot of contamination making it hard to weld an edge that has been ground on it.

Back when I was still working with aluminium full time I was using a bevel cutter similar to this combined with a little bit of kerosene to combat the sticky nature of aluminum.


You can even use a (table) router to achieve similar results on aluminum.

[adbuch]

Plasma-art - thanks for sharing that information. I agree on the belt contamination, both to the belt and the part being ground on. I assume the beveling tool you show uses carbide inserts (haven't watched video yet). Using a router is another good idea. Could also use a carbide burr in a die grinder.

I did not look up the price and yes that is pretty steep and yes they use carbide inserts.
The results of a table router with a fence and a 45° bit with swappable inserts would be similar.
For light work in aluminium only even a cheap palm router would do the trick with the correct bit.
There are pneumatic beveling tools these days but I dont think they are able to do generous chamfers.


For aluminum you want a real aggressive burr in a die grinder, the regular ones also clog up with aluminum before you know it.
Something similar to this one however I would not cheap out because cheap ones are not really as sharp as you want them to be.

A die grinder with burr wouldn't be my first choice for chamfering aluminum (or steel). Of all the methods mentioned, I think using a wood router with appropriate bit would be the most economical. For me personally, I would use my milling machine with uncoated end mill.

I have a job that I use 1 1/2"x 1 1/2" x 3/16" wall aluminum for. I chamfer it so I can get more penetration and it's faster to weld etc...
I use an angle grinder right now with discs that are meant for aluminum.. I would buy belts or discs that are for aluminum as well.
Anyhow I think it not only would be a bit faster but my hand won't cramp while beveling LOL.. I bevel 100 pcs or so at a shot..
Thanks for the input guys

I think using a disc sander (not belt) would be best. Anywhere from 8 to 12 inch diameter.

Ok so just a bit into this, This is what I'm leaning towards.
I like your grizzly with how you can put it on a bench, as floor space is limited.
My problem is that so is bench space LOL....
I like the fact that the one I posted has a motor in the base, I think these motors are generally cheaper to replace, I like the feature of the dust collection, I'm stupid and probably wont use it but I like it..
Thoughts???( On the sander you bastards, not my stupidity)
Thanks

Chris.. would something like this do what youre after?
I posted about the chamfer tool and saw their new table and thought it might work for you.


BTW, the last sander you posted is similar to what i have in the shop... i love it and use it almost daily.

[SeanP]

I always intended building a belt grinder, but just never have a minute these days, bought one like this last year, works great.

The swag tool is interesting, but I'm afraid it wouldn't be quick enough, another downside might be longer pieces and holding them in the air..
Thanks for the input.

The grizzly you posted is made for steel, the ones I posted are for meant for wood.. Do you think there is a difference with the ones meant for wood???
I know there is a difference with time savers...
Thanks in advance..

[Plasma-art]

came across a belt sander for wood a couple of times that ran considerably slower.
You obviously need a lot less speed and power to sand wood.
This was in Europe but might be something to watch out for over there.

Anyhow I think it not only would be a bit faster but my hand won't cramp while beveling LOL.. I bevel 100 pcs or so at a shot..

For those amounts I would get a cheap palm router with carbide inserts bit.
You have the option of using it in hand or cut a plate you can mount it to upside down, those palm routers almost always have a hole pattern in the base.
Another thing you can do with a palm router is strap it to the plasma cutter and use it as a cnc mill

The difference is the rpm. The sanders for metal generally have a higher rpm. The sanders for wood are slower so they don't burn the wood.
David

This is the one for wood.
https://www.grizzly.com/products/grizzl ... -rpm/g1276
The sanding belt speed is a low 2500 FPM, while the disc speed is 1725 RPM


This is the one for metal.
https://www.grizzly.com/products/grizzl ... nder/g1183
The sanding belt speed is 5000 FPM and the disc speed is 3450 RPM.
For woodworking and metalworking

[cstroke]

I was getting ready to comment on the speed difference 5000 has to scream...
I looked at Balleighs metal sander and it's similar to the "wood" one I posted the link for speed wise with the belt and similar in the disc speed.
