Just thought about this Friday when i went back to get material to build this toyota flatbed.
For ANYONE who needs/wants metal of pretty much all types, let me know. it might be worth your drive to my buy in Granite Falls. He has his steel very well organized, square tubing, rectangle tubing, angle iron, pipe big and small, few pieces of tubing in there somewhere, 2x4x.25" 20ft and 24ft, 2.5x2.5x.25" 20ft and 24ft...etc etc. He has a whole stack of 2x4x.120 4ft pieces about 40 of em, 2x3 same stuff, just all kinds of random steel that he gets from industrial businesses and scraps what is scrap and keeps what is worth keeping to resale to guys like me...he sells it for .30c a pound but the more you buy the better the price.
Then there's the random "scrap" pile where I get sheets, and heavy wall stuff that comes in every so often...but this pile on a good day has 6ft and 8ft box-blade pieces and other "tractor implement" type pieces in it. I used to weld for that place so that's how I know where it comes from. Friday there was 2 6ft box-blades in the pile that were little out of bend and the guy is so filthy rich, he just tosses it when the angle is out like 2* lol. Might be worth a drive for anyone building a rig and needs metal on the cheap.
he's got like 6/7 pieces of 1/4" 4x8 sheets of some hardened steel stuff...
4 pieces of 3/8" 4ft x 3ft pieces
lots of 10gauge partial sheets (you can't have those LOL, their mine hehe)
 
Toyota flatbed coming along..most peace and joy I've had in days

the guy takes so much pride in the product that comes out, he scraps it and eats the cost just tosses it when the angle is out even 2*.

FIFY
 
so today was my first time cutting clean metal on the CNC table and it was cutting really different (clean like stripped down looking really shiny)...like super clean smooth cuts. The metal I've been using is pretty clean, used and been sitting outside at the yard I get it from but has that black stuff that comes on all metal...does that stuff on the metal really make a difference or is my machine just cutting good cause it was 27* in there lol (like a dang fridge in this place)

Yes clean metal matters. Cold roll steel or PO steel makes a huge difference.

good to know but dang, that took forever to sand down a 30x60 sheet lol so doubt will be doing that every time. Amazing the difference it made
 
The plasma torch is making an electrical arc. Just like welding. Clean metal makes a huge difference.

i kinda figured but was surprised at how much a difference
 
HRP&O has always been used for mass production plasma and laser vendors that I’ve used in the past. Clean and very low scale for minimal added cost.
 
Can you simply use a sander or flap disc on the sheet steel?

I use a big wire cup on my big grinder that works pretty good and quick for me when cleaning up rusty metal .

Mill scale. Much tougher. Burnished metal also doesn't take secondary finishing like paint and powder very well.

Your right about this..it took hours to strip the 30x60 sheet to bare metal. That stuff sucks. Even annoying to weld through
 
Almost done

Curious on the gauge of material and amount of frame work under the bed? No usable tie down points or stake pockets? Is the head ache rack through to the frame or surface mounted to the skin of the floor? Sprayed with rattle cans?

2" square galvanized tubing for box frame. 10g for the bed and bumper. Tool boxes 14g, headache rack 14g tying down to the frame of bed with 1x1.5 14g tubing. It's just for looks he wanted. Rattle can for now, he's getting the entire truck repainted soon so bed will get sprayed as well professionally
 
I’m planning a flat bed for ‘Mater sometime.
