chopped and dropped

I thought that you were supposed to cut the frame at an angle and fishplate both sides?

I know a guy who does alot of frame stretches. He cuts the frames in a step shape so that he gets more weld on them. Then he plates both sides. Everyone does them differently, but this particular chop looks plenty tough.
 
$50 for the bed....You suck... I gave $300 for the one I have setting at the barn.....But mine did come with a 1/2 ton frame LOL

$50 + his old bed....atleast thats what I think I read.

correct. my old bed also had a rather large hole cut out of it for the fuel cell though LOL.

as far as the ways to cut the frame, people do it a lot of different ways. I prefer to cut it straight, weld it solid on the out side, and some stitching on the inside. and fish plate the outside.

NEVER fish plate both sides, you will weaken the frame with that much weld.

by fish plating the top and bottom, i can pretty much guarantee that section of the frame is stronger than it ever was before it was cut.

but like i said, everyone does it differently.

Exactly. I don't see anything wrong with the way you did the chop. I was taught to do it this way & stitch weld the entire length.

hit the bed with some rust converter today, we will see how it does, tomorrow im going to do the inside, im debating on dropping in a bed liner, not sure if its going to be extra weight that i dont need.

It looks good. Why not do a roll on bed liner. Would probably look better than a drop-in. They seem to hold up well if you do the prep correctly.
 
my old bed was rhino lined, wasnt too impressed, hopefully ill find a craigslist freebie drop in.
 
Looks great! Good to see you back around.


I'd love to do that to mine. Pretty cool that you welded the drive shaft and didnt have in vibration problems:clap:
 
thanks man.

we took her out last night, its like having a whole new truck, the increase in speed just due to actually putting power to the ground is unbelievable. put a good 4 or 5 cars on a cobalt ss and i wasnt even shifting hard.

i cut 16.5" off the driveshaft and welded it back together, the local shop was so busy they wanted $200 to shorten it, so i did it myself, no vibrations, but seeing as the shaft sees maybe 4000 rpm (and by that point id be doing 130mph) i really wasnt expecting any. even if it does vibe and eventually breaks, i have drive shaft hoops.

If you dont feel any vibration, you should be good. But be careful because if it starts vibrating, its likely to crack the tailhousing on the transmission. My cousins 5spd had a U-Joint go out and it cracked the tailhousing on his.

I cant see the pictures for some reason, so i cant really say good work yet:hehe:

How did you go about shortening the driveshaft? I need to shorten mine about an inch and thought about doing it myself, just not sure what the best way to go about it is.

i measured all the way around the driveshaft, cut it w/ a cut off wheel. when you get it apart youll see how the yoke flange is put it, youll have to grind the weld out, then hammer it out, and press it back in to the tube, make sure the yokes are aligned to each other, and burn her in, i did it in 6 welds, jumping around to keep it from pulling, because i dont have a drive shaft lathe.

im working on getting the pics up, not sure what happened
