Thanks mate, hopefully you're eyes are sharper and hands steadier than my 54 year old units.

TIG - to look good - is a very methodical Dip move dip move dip move. I think new welders get mesmerized with not trying to burn through etc but then kind of freeze up...

Practice the rhythm and the rest will come.

Also - I think you have too much heat... which will cause you to struggle with too much thinking about burn thru... back off the heat until you're struggling instead with making a puddle... then up the heat just a tad... now work on the rhythm.

You have only got 2 years on me, I don't shake but glasses are defiantly needed.

Wait til you guys turn 60.... by then your practicing and skills should make up for what you can't see...

The only rhythm I have is in my music collection............



I don't have enough time under my belt to grasp a feel for the ratio of heat, speed, and filler to puddle advancement.........yet. Practice practice practice!!!

I'm not sure if this is the right place for this question, but here goes.
I noticed in the Fairway Chevelle thread that the exhaust is mounted to the frame with tabs. Does stainless tubing not grow when hot like my aluminized tubing on my HEEP? My exhaust on the HEEP grew about an inch and a half when it is running. Would it not be better to use the rubber hangers that the bar slides into to hang our exhaust on these cars?

THANKS

Good question -- with many variables to the right answer. Is there a "bellows" added to the system? Is there a woven stainless coupler in the system? How much horsepower? Turbo'd? Blown? Etc.... it's all about the heat in the system.

I personally have installed both styles of hangers.... but I always use a woven stainless vibration / flex couplers which I think helps with the "movement".

The stainless steel exhaust in my '32 (which is very short) grows an inch - and I've had nothing but issues with it because of the way it was hung (I didn't built it) and I think adding a flexible coupler would have solved the problems.

Greg,
Thanks for the reply. I saw the stainless bellow and I agree that will help with vibration and some growing. However, I'm wondering with the exhaust tied to the frame in at least two places, if it will push forward to the headers. do you think the bellow will take all the slack? Seems like it will start putting too much pressure on the headers.
Now, please don't get me wrong, I know ironworks knows what he's doing, i'm just going from what I saw on my HEEP. I don't want the exhaust to be a problem on my Chevelle.

Thanks.

Personally --- this guys slow talking drives me crazy -- but he does good videos... and you'll learn something from him.

Guess I'm supposed to watch it huh?
