Frame Boxing Question - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I am getting ready to box my frame rails and just want to make sure I am planning correctly. I was going to cut the steel to the size of the inside of the frame rails, grind the edges at an angle, then weld them smooth to the inner edges of the frame. Does this sound correct?

Are you angling it from top to bottom. Or are you tring to make it square with the bottom having a lip. Use long pieces of card board to make templets. Weld spot to the corner. Weld from bottem to top front to back little welds at a time at 35-45 degrees. Keep the metel from getting waves. Bevel the plates at 45 at top and sides for the butt weld. Hope that helps.

I'm not trying to be a smart a$$, but why would you want to box the frame?? Really an honest question.

I guess that I need to ask the same ? My thoughts are... if you are racing, you may benefit from the boxed rails. But then again, a good roll cage should stiffen the old truck up enough for that fun. On the street, I see no need for a boxed frame.....

Thanx Simon. I forgot about the fact the lower lip is wider than the top. I am planning on making the inner plate straight up and down. So I will have to work on that.

With the open c chanels and even with the roll cage the frame will still twist up a little. Alot of the old hot rodder weld up the frame to give it a nice clean look.

Ask Mike Rowe on the Ferd commercial. Stronger frame. Not necessary for a daily driver, but if you are racing or pulling max loads then it is besides smoothing the frame for a show truck. That is the biggest reasons to do it.

For the killer looks factor, how 'bout building a new frame entirely, from 2x5 or 2x6 rectangle tube...? Helluva fun project, I think. And from the condition of the frame on my truck....it'd be easier and faster to start over than to box it (massive infestation of rust) A boxed frame would be slick though. Anyhooo, my $0.02 worth of
