And yes, this is the truck I rescued from the junkyard.

subbed. I'm always impressed at folks that can do this kind of work. Very cool.

Re: A different approach to a LWB to SWB conversion
"Here are my scribe lines on the front of the bed side. One for cutting and one for tipping over the edge."
I'm curious how much material you left to tip over the edge, looks like an inch?

Re: A different approach to a LWB to SWB conversion
My wife wanted it cut down. She didn't like the look of the long bed. Pressure from her made me convert it.

You have some fine fabrication skills, I like how you are doing the bed.

Re: A different approach to a LWB to SWB conversion
Great fab work, I always wondered why no one did the bedsides like this. I am curious how you do the rear half of the bedsides though. You obviously know what you are doing and I understand the difference in frame welding from a guy with a welder like me to a real cert welder like you. Keep up the great work.

Re: A different approach to a LWB to SWB conversion
No need to get defensive, I just don't want anyone else thinking this is the proper way to weld a frame. Welding is not a mystery to me. If we're throwing experience out I will tell you I've been welding for about 40 years, but a journeyman for only about 30 of that. I have a fair amount of both formal training and experience with heat treating techniques and practical experience pertaining to a variety of metal, including mild steel. To not acknowledge the change in space lattice and the resultant vertical stress points just doesn't make sense. Without heat treatment that frame is weak on each side of the weld. Not opinion, fact. Either most every frame shop in the nation doesn't possess your talent or fish plating is an industry standard for a reason. I appreciate your craftsmanship, but would not do a frame like that anywhere but maybe the ends. I hope anyone else doing this consults more sources before they proceed. Good luck!

The weld is the same type of weld used in piping. Nuclear plants and any other plant use full pentration welds with beveled ends. No difference. Nice job man. Being a common weld with QC inspections for the full penitration. Certified welders can do this with no problems. As stated most people are not going to be certified in this type of welding. It takes years to gain this type of certifaction. It takes even more practice to keep it.

Re: A different approach to a LWB to SWB conversion
Any of you certified welders know what the reduction in material allowables is due to welding? We could do a quick axial and bending calculation on the frame and see if it's anywhere close to Fty. My guess is that with a good weld and a 3 ton load at the rear bumper, it should be no problem with a C20 frame.
At least the analytic calculations would stop the conjecture whether it will fail or not. I think this method of cutting down a LWB could save a ton of welding and body work. I can't wait to see the final product and how you tackle the hardest part. |

Maybe since its a thicker frame than any Swb that ever left the factory with, it will have stresses low enough to not be an issue, but so much of it depends on usage (loads and miles driven). A fishplate or formed channel insert just seems like cheap insurance. I like what he is doing here otherwise, this seems like a well thought out way to shorten the bed and Im on my toes to see how he does the back part of the bed.

Okay, can we stop the pissing match and get back to the "outside of the shortbox" thinking here? The man has talent and great imagination, Lookin forward to more

Re: A different approach to a LWB to SWB conversion
I'm wondering why this guy is catching so much trouble here? I've welded two things in my life, so would I try this, no. Dude has been welding 30 years, and by reading, does it everyday. I'm sure he wouldn't do something that isn't going to work. Has he told anyone to do it his way? He made a build thread for us to look at, not junk up with a bunch of middle school crap. Send him a pm if you want to tell him his way won't work or whatever. Maybe it's because he hasn't built a truck on here yet. Not that I want to drag others in, but what if superflysteiny did this? I almost bet no one would say a word about it.
*Eric, I love reading your builds. You're a household name around here. Just used you as a point guess you could say. Now, I'd love to see these besides, please continue sir. Tom

Re: A different approach to a LWB to SWB conversion
I'm not sure this thread will last much longer if it becomes a massive critique about what one man decides to do with his property. I for one would like to see it continue on the right track.... perhaps with pictures of shortened bed sides

Re: A different approach to a LWB to SWB conversion
From my point of view, the phrase "Ignorance is bliss" comes to mind. Cuz I'm really liking this guys work and I don't know all that much about the practical aspects of welding and metal work.

Re: A different approach to a LWB to SWB conversion
Very different approach and I am enjoying following along with the OP as he goes.
I don't want to lock the thread either ![]()

Re: A different approach to a LWB to SWB conversion
Great thread. Here's the thing if your a experienced welder and you feel comfortable with this then do it, but if you haven't welded much and are going to attempt any structural changes to the frame then by all means use the plates. Or better yet have a professional do it. I'm sure the OP will check the truck regularly and I'm sure the other guy just wanted to warn the people thinking to attempt this. The site is great for ideas and help but always research a lot before attempting anything yourself.

Re: A different approach to a LWB to SWB conversion
I like it! I want to see the bed work. PLEASE continue!!!
Are you sure you're not a magician? How do you get that metal to bend like that? Mine would look like Hail hit it.
