Welding in a K frame

#41 said:
One advantage to having it bolt in is being able to replace it. Damage can happen easily if you run into a curb, over substantial road debris, etc. I have never destroyed one personally, but I have bought a couple parts cars in the past where the K is wasted and the easy fix is to bolt another one in.

So you would not trust a welded sub frame?

Love to be wrong the K is the best and motor mounts are also and the best gears are between 3 and 7 and the list goes on.
 
I think you should quit posting and get welding. Interested to see how much better it is when it's done. Good luck my friend.
 
Still going strong....

Still no comments on welding a k or it will fit or how to mod it?

7018?
Click to expand...

7018 is a 70,000 # tensile strength material all position stick electrode usually designed as a LH rod for low Hydrogen flux to prevent inter granule cracking. For first pass, try 6010-5P (red wire) for better penetration, then use LH7018 cover pass electrode OR 7028 JET WIRE if appearance is important. 7028 should only be run in flat horizontal beads. However, if using MIG, ER70s electrode wire using either 100% Carbon Dioxide gas or C25 gas that is 25% Carbon Dioxide and 75% Argon mixture, is a good choice.
BTW mild steel is considered a low carbon steel ok for fence posts and non critical applications but 1020 carbon steel or 1045 carbon steel for higher strength applications may be better. Thd higher percentage of carbon adds strength noth in tensile and bending.

Do you think it will hold a motor mount?
