Default Corner beveler???

I'm going to be welding up some fireboxes for a couple BBQ pits. I have a custom pit that I had built by a professional pit builder and the outside corners are so square/straight that I can't imagine they were dressed with a grinder. What do I need to do this?

Is there a beveler for 90* angles? I looked but most are 30* or less it seems. Is there some other device I should be looking for?

Thanks as always.

Maybe they were formed using a brake, and not welded.

Two of the corners were bent but the side with the door on it was welded I'm pretty sure.

Edit: I just remembered. It has to be welded. The door side is 1/4" while the rest of the box is insulated with 7ga outer and 1/4" inner.

I don't know about for a steel grinder, but I've seen them for use in granite shops. I'm pretty sure makita makes a whole unit, but this pic was the first one I could find online anywhere of a similar setup. A feller should be able to rig up something similar on his own.

though this might work better for doing a 90 deg set up http://www.heckind.net/weldshaver.htm

with some care, and using sanding discs, you can get a sharp 90 deg corner. its a pita- often you end having to go back, fill little gouges and nicks with weldment, then regrind.

Default Wekcine MKing!

Why is a sharp 90 Degree bevel needed for a firebox?
Is it just for looks or is there some functional reason?

Why not just square it up on a 4" belt sander with the table set at 90 Degs?

I have a Jancy plate beveler somewhere, big, heavy, loud and hot chips everywhere, its really more of a PITA to use than to just using a grinder.

I could have made good use of one of those bevellers for a project I am working on............................did it the hard way with a cutting disc on a side grinder, and a burr in a die grinder.

Purely for looks. Higher end competition pits are $10k+ so looks definitely count.
