what does everyone use to cut their frames with.

TX_Mudder · 05-15-2003, 06:46 PM

I haven't done it, but I would probably use a 7" circular saw with a metal grinding blade. Would be the easiest way to make a nice cut.

i use the good ole hot wrench " CUTTING TORCH",, just remember if you are going to do some welding on it never weld verticle,, you will only end up creating a weak spot,,, always cut the frame at a about a 45 degree or more angle the weld that and plate it with 1.4 inch plating then you can be pretty safe feeling

First, I marked the area to be removed, 2 marks down the frame. Then I made a rough cut with the cutting torch and left the frame an inch longer than needed. Then I made the final cut with a porta-band saw. I then cut on the frame on the other end of the part to be removed, then pulled it together and welded it. I then took the piece removed from each side, cut it longways and removed about 1/2" then welded this piece inside the frame for extra support. Remember, the worst thing you can do is to get in a hurry. Do it right the first time.

The best frame splice I have even seen on these trucks was done by EFABMAN. Do a search & you might find it.

Mudder · 05-28-2003, 10:54 AM

agreed with Zoomy. I kept those pics just for me.

If you cut it at a 30 degree angle instead of a forty five it will be considerably stronger. Just a thought from a young punk fabricator/ wanna be engineer. If you don't believe me look at crane booms or steel over head fabricated beams. All have 30 degree angles in them. Good luck

ozarkhippie · 06-20-2003, 11:57 PM

you can use a sawsall

ljbear · 06-21-2003, 02:02 PM

I think the way Earl (efabman) does it beats them all. More surface area along the joint is the way to go.

I have used a sawzall to cut frames with no problem. When I tore the frame in half on my 85 K10 the frame shop pulled the frame back together, welded the seam after ginding a V into the break and plated the inside and bottom of the frame. What he did that I noticed was a little different is that the plates he fabricated for the back and bottom rails had several 1/2" holes drilled in them and the holes were filled with a weld bonding the center section of the mending pieces to the rail as well as the edges.
