Four point tack

[Buzz]

I am building a Front engine dragster chassis. I've set up my jig with holding clamps for the chromoly tubing to keep everything stable. My question is if I put four point tacks on all my joints can I remove the chassis from the jig to complete the welding process so I don't have to stand on my head or play the equivalent of "Twister"

Sorry but you will have to learn to stand on your head. The jig holds everything from pulling around while welding. Scott.

Front engine dragster? Why don't you just buy a rear engine dragster and run it in reverse? Kind of like a sports compact dragster with the big tire in front. LOL

Sorry couldn't resist?

I try and tack as much as as I can and get the diagonal braces, or "X bracing in if at all possible before doing any finish welding. When you weld you can weld a little on one side and then weld a little on the opposing tube to conteract the pulling or movement of the tube. Make the forces work with and agaisnt each other .

Hey 1320Fabrication are you happy with your 375? Mine does not seem to be up to the task.. Upped the input electrical line & about to put a extra dryer in the air line. How does your's perform?

The 375 does well on thin stuff like cutting out floorboards. On thicker stuff it helps to have a fairly new tip. It could stand to be a little more powerful.

I've got the Motor Gaurd M-26 toilet paper type dryer on mine.
