I started with the Flux core .035 wire, but on advice from others, I cracked open the wallet and converted the setup to Argon and .030 solid wire. It does make a mediocre persons welding skills look almost competent!

I guess it boils down to technique and making a few adjustments. The weld appearance and penetration is far superior.

I would have to look at my reciepts, but Im pretty sure the mix bottle is more expensive than my pure Argon bottles I use for TIG. Either way, its better than flux core! Kyle Curley

Straight argon is for TIG and aluminum MIG(spool gun most commonly). 6-10% CO2/argon is for spray transfer MIG, which is typically heavy duty production stuff(very uncommon for 'hobby' use). You can use straight CO2 for MIG also; little hotter, litle more penetration, little more spatter, but fully workable. Hobart makes an adapter kit for using paintball bottles w/MIG machines, which is nice for 'at track' repair/patch work. S/F....Ken M

I pressured washed the grease off of mine and then lightly sand blasted it so it would be clean and easy to weld. Wrong, I found all the grease inside when I started welding the edges. So stopped and got 95% of the grease out so I could weld the edges. Maybe stupid or over kill, I wanted them welded. I can say it all made a huge difference in how my 71 handles compared to my stock 74, big difference for the better. Worth doing for sure. I used .035" wire with 75/25 gas. Before, it was pretty much bare metal from light blasting, then got rusty when I had to steam clean the inside a second time. I had planned on blasting a second time after welding. Nothing warped and it fit right on the car. I went over every factory weld, some even missed! I mig welded most of it. I tig welded the washers and lower control arm reinforcement plates. Got another sand blasting before paint. Wet paint! almost forgot to take a picture of it bare. Shouldn't grind on a weld. Last one, eye candy. Factory sway bar laying on the floor.

I wish that my skills were good enough to weld and then paint the stuff that I do. I'm trying to improve, but I still need to "tune up" what I weld. What is the reasoning behind the statement? A weaker joint? In most cases, I just knock down globs or high spots. Somebody wrote in a post somewhere else in this forum: "Pretty welds are not always strong, and strong welds are not always pretty." That gives me hope!

I have the Hemi style mounts and if I weld any more bracing on it, the engine mounts won't fit. Will the lower sector support provide enough stability that I shouldn't worry about it? Tim

So if the sector shaft is held solid to the K and you still have flex what takes the load now? Yep I've seen it in Dodge trucks that have the sector braced but the frame still flexes. Mopar to the bone!!!

This makes 2 points of support if the add on kit is added. I'd think that it would be unlikely to flex enough to cause damage. The oil seal may deform under some stress, but if everything is in good condition, I see no problem. I didn't understand the reasoning regarding the shortcut in steering box supports a few posts back. Maybe the HEMI mounts share the same space? I agree with Steve, the strengthening of the steering mounts should be the lions share of gains of K member welding.

72Swinger master Joined: Feb 2011 Posts: 4,302 Nebraska	During steering that extra support bearing is awesome. During flexing,whether it be the K,aluminum steering box or steering box mount, the support bearing isn't going to always flex along with whatever is going on, or flex at all. So that support bearing can actually act as a cantilever and apply force to the sector shaft and its bearings. My point is I think bracing the box mount is important even with the support bearing in place. Last edited by 72Swinger; 03/28/12 08:30 PM. Mopar to the bone!!!
