I was thinking about staggering the cuts and fishplating them. would it be better to make a straight cut, angled cut, or multiple angle cut to aid in structual integrity. a lot of questions I know. just always looking for the best way. thanks guys

Just be sure to have a welder that is certified to weld out of position do the welding. Also, fishplating isn't neccesary if the welding that is performed is full penetration and good quality. Boxing the open side of the frame in the area being spliced would add more structural integrity than the fishplating. Since your in Texas finding someone with a welding rig to do the welding should be easy enough, that is unless you are a certified welder, if so my hats off to ya.  Hope this helps.

I've been accused of over engineering before. I gotta figure out how to squeeze some pictures into this fancy computer thingy and I'll take before, during, and after pics.

Go to a metal shop and have them bend you a piece to go inside the frame have it go as far as you can on each side of the weld. you should use 3/16 or 1/4 inch plate your frame should be 3/16, don't use anything any thinner though.You want the inner frame to be a tight fit, after you put it in do not weld it,that will cause your frame to brake. Bolt it on each side of the weld, use grade-8 bolt 1/2 in will be good for that. That will fix your frame and you want have any problems with it.I'm a welder/mechanic and this is how you cut semi-trucks and put them together, I've done alot of the.Hope everything works out good for you. | | |
