I think that might help clean up some of my welds!
I think your description of the “pooling” of the metal is pretty accurate. It is almost like it puffs up the metal as your grinding disc grinds the lasered area smooth without touching the parts of the metal between the passes.
I made a couple corporate signs over a few days. 1/8" HRS, used muriatic acid to remove the mill scale, then a Burnishing Polishing Machine to brush the surface, followed by 3 clear coats.

I watched this guy and followed his instructions (wasn’t using corten).
This is great
lots of good info and hes pretty funny!
I had bought some 8" ish diameter red scotchbrite wheels for a bench grinder that I stack up in 3’s and use for polishing up stainless and whatnot. I may have to pick up one of these machines. I get tired of the bench grinder building up static in me / the part and then getting shocked every time I try to touch anything.
I made one out of a DeWalt buffer. The Vevor one will work great. Mine uses 3 x 15.5 belts on a rubber roller that expands
Ha! That’s not a terrible idea. I’ve got a 7" D[ewalt] grinder mostly gathering dust in a drawer as my 4" one is my workhorse. Saves having to shell out for another machine to take up space. How did you make the adapter arbor and what’s the roller? Where do you get the surface conditioning belts from?
The rubber 3M wheel costs more than the buffer, though.

If I could do it over the Vevor would be my choice. You could buy three for the cost of the rubber wheel. The belts come from McMaster carr. 3M sells the arbor for a 5/8 shaft buffer.
@Bigdaddy2166 did you do the hydraulic conversion to your 52" inch shear?
I have a Tennsmith 52 inch here which is basically exactly the same is your machine but manual. I had looked at converting it to pneumatic.
Air cylinders. It will cut some stuff. Its very fast action is almost dangerous. If I did it again, it would be hydraulic. It has an air tank with an air pressure amplifier installed. It bumps the 125 psi air in the small tank to 250 psi.
Yea, that’s scary.
Works great. I just don’t let anybody use it except for myself.
Noted. That’s pricey for a dang wheel.
Yes, Its works great but… You can get it cheaper. I saw it for $128 online.
Are the cylinders pushing on the main deck of the shear?
I’ve killed myself over the years cutting 14 gauge stainless with my machine. The vast majority of what I cut is 26 gauge galv.
Pushes on the arms. It will cut 1/8 3000 series aluminum at 4 ft wide. 5000 series about 24 ".
T6 is out of the question.
on the top of cylinder?
A welded bracket is bolted to the side supports. The bolt holes already existed. Hydraulic is the way to go. The control travel speed factor is the key.

Might enjoy laser and telescope.
I am NOT doing this but it was fun to watch.
