Cutting bedframe for brewstand?

**Bobby_M** · 11-30-2007, 03:08 PM

I hacked up about 20 bedframes to remove all the rivets and fittings using my angle grinder. Now that I'm ready to start cutting pieces to make the stand, I'm having trouble figuring out how to miter. I've got a 10" miter saw and bought a 10"metal cutting disc with the correct 5/8" arbor size. Unfortunately, the disc is like 3/16" thick and takes forever to cut through the metal. I'm also getting pretty close to melting this plastic strip that sits on the bottom of the fence.

Does anyone know of a more appropriate disk for this purpose? I looked at the 4" thin disks from the angle grinder, but the arbor is 7/8" and too big.

Man, I hate cutting metal. Do you have a sawzall? There are some metal cutting blades for those things that go thru rebar pretty easily. They may work for your frames too.

If he's mitering, I'm sure he's looking for a bit more precision than a sawzall can provide - just ask BierMuncher how accurate those cuts are!

You might be better off cutting them with a sawzall and then putting the angle on them using your grinder. I haven't ever tried to do a miter angle on metal but I know it doesn't like cutting square a miter has to be real bad.

Actually what might work best is a band saw if you know anyone that has one.

Get a $15 angle grinder from harbor freight. much cheaper than fubaring your table saw.

make a jig by screwing a piece of wood to the angle grinder that will give it a flat reference surface. Then set up a fence guide that will hold the angle grinder at a 45° angle to the clamped down metal.

I have a few more thoughts, thanks for the replies. Actually I put this disk in my compound miter saw and yes I'm trying to do 45 degree miters. If I could just find a thinner disk, I'd be ok. I suppose I could try the idea of clamping the angle grinder to my table saw fence and using the sliding miter table to hold the angle as it approaches the disk.. That just might work.

My bad... I didn't think to look at Mcmaster. They have a billion different sized/thickness/grit cutoff wheels all day long. When in doubt, check Mcmaster out!

Oh, and if you're cutting your kegs up, check out this stainless specific wheel:

Assuming your mitre saw is a 12" or 14", Dewalt makes ferous metal cutting blades. These are steel blades that do not have the deflection that the carborundom style bades do. They are the series 77 blades. the 12" is model 7737 IIRC. Much more acurate in my opinion.

It's a 10".... smaller than I'd like (the story of my life hehe....)

Why miter? Would that be the strongest joint for a weld? If the joint isn't perfect, you'll definitely have some fit/level issues, and some of the welds might be difficult.
