You can’t trigger me. I got to drive my pig today for the first time in many months.
I am beyond excited for you, no one deserves to drive a new pig project more than you! I cant wait until you get to drive the rest of them..
But on street-driven vehicles? I’m gonna quote the best opinion I ever heard, “it’s a hobby, there are no wrong answers.”
You're 100% correct on all accounts and I don't believe I've said anything different.. My questions to the rest of the peanut gallery should have been phrased differently to exclude you and I'm still sorry for making you sad.
Seems to be silent on the subject, fren. Got a page number?
I started this thread and said I have certain beliefs on the subject of automotive frame repair and modification, I’m not an expert but my beliefs are mine and if anyone is willing let’s talk about the subject and see if we can learn something new and maybe help someone else in the process.
You have made comments like.
“ I'm sure I've forgotten everything I did back in college on finite element simulations of welded structures, so you're probably right.”
“If you want to continue, let me know if you're asking about notch stress concentration factor of fillet welds or something else.”
You sounded at the time like you might have some real knowledge on the subject and “YES” I did have and still do more questions but didn’t want to offend you by asking them somewhere inappropriate. I felt like this was the right place to ask questions and talk about interesting subjects that pertain to building 4X4 station wagons.
Early on in this thread you posted a link to a weld theory book and said that book would answer all the asked questions, later you said “Please reference section 2.2.3 (p 13-14) of the work I posted first in this thread on why controlling your weld pool (“puddle”) size is important”
I’ve read that section and a bit beyond and asked you “as someone that has read all 267 pages” what are your thought on this “new” technique of making your MIG welds on steel look like TIG welds on aluminum (stacking dimes). You didn’t give a direct answer and said you are just getting back into it so I gave you some examples to explain the process with a video showing a couple guys that are very good at it telling you to turn the machine down and use smaller wire stacking weld on top (cold joint) to give it the TIG weld look. I posted a second video with what appears to be an older guy saying basically the same thing and doing some testing but giving his opinion on why you shouldn’t do it. J F Lancaster talks about proper weld penetration in the “book” and I agree if we are welding for strength the stack of dimes weld is not a process we would do, it should be considered ornamental welding and limited to non-critical areas if failure would cause harm.
Since you Bob and I are the only ones asking each other questions and he and I mostly agree on everything would you mind sharing your thoughts on supporting a frame during welding?
When you were in college and sitting in your finite element simulations of welded structures class what did they talk about warping the structure during the process?
Hope you have a great day and get some quality miles on that new pig!!
