Those frame rails have some serious arch to them. Going to take some long shocks... I thought I was nuts for fixing my RoadRunner. It's looking good though. Do you have AMD on speed dial? Jeff

What size wire are you using in your mig?...and is it a 110 or 220 machine?.....what type of gas?
I'm using .035" with 75/25 argon/co. It is a MM251 run on 220V. I think I had the setting on 16.5 with 250 wire speed (recommended for the rail thickness). I did some practice cutting it down to 215, and it was better, but still not like my horizontal welds. I will experiment with maybe 180 wirespeed with same voltage and see how that works.
I was using the inverted "V" pattern, but need to get better OP control I guess. Practice, practice.
Greg.
what PSI are you running the gas at? Also you might go to an .030 wire.... the smaller wire helps control peaking and puddling. .035 is more for 1/4" and up.

It is set at 25psi. You are right about the wire. I didn't have any .030" spools, but I should pick up a spool. Thanks for the advice.

No "V" when doing vert up. Just zig zag back and forth. Pretty much straight across and just a hair up from where you were on the previous pass.
I hope you understand what I am saying. I'll try to draw a picture.

Think of it like the conductor of an ochestra.....waving his wand back and forth in an arc.

I understand exactly what you mean. I saw a video from "welding tips and tricks" and the guy did the inv. V and the weld looked better than my horiz welds. He said it penetrates the corner very good with that pattern, so I tried it.
I'll try going straight across like you say. I think I need to climb up more slowly. I have to just stay in the front of the puddle, and I might be pulling away to much. Maybe that;s why my weld looks uneven and ,well, "Crappy"
I'll let you know how some more practice works. Thanks.

My Road Runner has pretty much been on the back burner until it warms up. No heat in my garage I'm taking a week off in May to do nothing but work on it. I should be able to get the cage welded in, wheel tubs, and trunk installed, then it will get put on the rotisserie. So what wheel, color combo is the Charger going to get when it's done? Jeff

It is going to be black (another black charger around...surprise surprise) and I have the Weld Prostars 15 X 15. I am using a M/T 32 X 16 slick.
What about your road runner? What color/ combo?
Car be be painted the original EE1 Dark blue, and 2 tone blue interior, just like when it was new. Going old school on the wheels.
No better color then black for a 68 Charger. Installing a Jerico is even better.

Looks like you pretty much have clearance for about anything you want to put about anywhere you want to put it!! What are you going to use for a car to attach everything to?? Just kidding. I am not trying to offend you,,,I just think that I would be sort of 'intimidated' by the project every time I went into the garage. I have gotten into some big jobs like this in the past, but, don't think I will live long enough to do one like this now. Good luck and keep us posted with pics.
Gotta' feel GOOD getting this far along ...Looking good!! Keep at it
