Cutting Thick With Small Tools

Can I get recommendations on the best way to cut 1/8 to 1/4 inche thick slices off of materials like wood and soft metal that are up to 4 inches in diameter?

I'm thinking of getting the smallest bandsaw that would accomodate these sizes,but I don't know much about how accurately I can do this.

Any advice would be appreciated.

Thanks.

Are you talking about cutting thin "cookies" off the ends of round stock? If so, I'd do it with a miter saw.

But if you're talking about ripping thin strips off lengthways, then I'd use a bandsaw. However, I don't think a small (benchtop) bandsaw will give you satisfactory service if your primary purpose is to cut 4" thick stock. You may manage to make the cut, but the narrow blades those saws use will be wandering all over the place. I think you'll need a standard 14" model to be successful.

Are you going to hire an apprentice to go and find them as they fly all over the shop?

A jig can be made where the "keeper" end is inserted into a block, then pulled or tapped out after it's cut. The jig will work on miter and table saws.

Personally, I'd do it with a decent, well-tuned 14" band saw with a zero clearance insert.

For round stock, a lathe and a cut-off tool.

Darren, Many metalworkers use the 4x6 horizontal bandsaw available from Harbor Freight, Grizzley, Northern Tool, etc. Accuracy is somewhat variable depending on how well the saw was originally built but I have been able to keep it cutting 4 inch rounds within 1/32 of an inch (0.062 ").

I'd recommend a horizontal band saw or power hacksaw (with appropriate blade [1])

The term "soft metal" is pretty vague. Are you contemplating brass, copper, aluminum, low-carbon steels?

Whatever metal is involved in this arrangement will determine your minimum bandsaw equirements. And yes, the other posters are correct ...if you are going to cut any appreciable quantity of this material you definitely want a horizontal bandsaw with recirculating coolant. The coolant also acts as a lubricant, reducing the load on the blade, bearings and motor and extending the life of the unit as a whole while increasing the speed of the actual cut. For cutting thick metals, you need a STOUT blade and high blade tensions on a VERY rigid saw or you are just going to make nested saucers, not disks.

DoAll makes nice saws ... but they are industrial in nature, built like a tank and priced like one, too.

Thanks everyone.

I can see that I'm going to have to worry about cutting metals with a bandsaw another time. I'll obviously have to outsource that work. Recirculating coolant is definitely not an option. And I need something with the smallest possible foot print anyway.

The immediate project will involve cutting 1/8 to 1/4 inch thick "plates" off of Delrin cylinders that are 4 inches in diameter, so I was hoping that perhaps I could get away with a 4 X 6.

Any specific recommendations?

Thanks.

A 4x6 bandsaw will cut that just fine. Use a coarse blade -- 10-12tpi.

With any such "first cut" material, you'll have to true up these disks on the lathe or mill afterwards.

Some that take the time to tune the blade angle are reporting very accurate sectional dimensions from consecutive slices of such material.

I have seen people report .001" over a 2" round

I'm still in the learning process concerning how to tune my mini-lathe(and mini-mill), but I guess tuning the blace angle on a bandsaw is much easier.

Though, that kind of accuracy is not a necessity. I would want dimensional consistency determined by the human eye.

Thanks.

I can't seem to find a 4 X 6 at Harbor Frieght.

I do have an opportunity to get a used 12" 1.1/8 HP Craftsman 2-Speed Band Saw for $100.

Any reasons to stay away from this?

Thanks.

'12"' sounds like a vertical woodcutting bandsaw. If so, the blade speed is WAY too fast for metal.

1) It's a Crapsman. Think "Blob Villa and Handyman Club of America". If that doesn't do it for you, think "Searz automotive fraud lawsuits" 2) It's probably a woodworking bandsaw with a speed which'll melt teeth off your metalcutting blade if it doesn't harden and crack it (rapid heat/cool cycles) first. 3) What're you looking here for? Weren't those two enough?

I had a feeling someone would say that. :-)

So I assume that no single band saw is appropriate for soft metals(Brass, Aluminum, mild steel), plastic, and wood, correct?

When someone mentioned a horizontal bandsaw with recirculating coolant I thought I'd just have to concentrate on a machine for cutting the plastic and wood, and have a third party do the metal cuts.(Aluminum, Brass, mild steel).

I still need to cut 1/8 to 1/4 inch thick "plates" off of one foot long Delrin cylinders that are 4 inches in diameter, and was wondering if there was any way to accurately do this with the portable band saw you directed me to.

By accurately, I mean consistent cuts from one piece to the next determined by eye.

Thanks a lot.

You may have written the above really early in the morning before your coffee. Anyway, steel, even low carbon (aka "mild") is not exactly a soft metal. In actual reality, you can cut aluminum or plastic fine on a saw set up for steel, but if you try to cut steel on a saw set up for aluminum, the blade will be destroyed.

Vertical bandsaws exist which either run in direct drive at speeds in the

800-3000 fpm range suitable for aluminum or hardwood at the lower end, up to softer woods at the higher end, or in backgear at speeds of 30-300 fpm for steels. I have never heard of such in a cutoff saw.

The 4x6 saw, readily available at many places, is your best choice. Or if you have good scrounging skills, look for a used Wells or Wellsaw and rebuild it.

Correct, but it's all in how much you're willing to get by with. A metal cutting bandsaw will work on wood but will be slower, and you'll chance getting coolants and/or grease/silicones on the wood. That could make it harder than hell to put a nice, clear finish over.

Depending upon the actual thickness, a wood bandsaw will cut soft metals, but you might have to do more filing on the edges.

Sure, just jig it up and use a stop for maybe a 0.020" accuracy, depending upon the jig precision, the blade used, and the speed.

Then he could look for an old Walker Turner, Delta, Powermatic etc variable speed, two range gearbox verticle bandsaw like the one you saw in my shop. 30fpm to 5000 FPM.

And no..not having any luck finding you a gear..sigh...but Im still looking.
