430

430 thermal expansion is only 60% of 304. Should have helped a lot with the weld distortion. Not that you would ever drive this through the salt of a Minnesota winter, but I had 400 series...

Heat dam

I humbly submit some advise to the Master. In past projects with similar, tube/rod edges, I minimized the distortion with a heat dam. A secondary gas purge (top and bottom) can also minimize the...

welding galvanizing

Automation

I have been lucky enough to work on many automation projects. Not easy. Invariably, in any automation project, the input materials become suspect. Sometimes material inspection creates more jobs...

ali tacks

Thanks Bill. I will give that a try.

You mentioned Oxy/Hydrogen. Do you use tanks or a generator for your hydrogen?

Flux and planishing.

Bill, you mentioned you gas tack and planish as you go. How do you deal with flux? I have tried TIG tacking but then can't get the flux on the edge between tacks. Also tried gas tacking with and...

square U bends

I have never been able to get square(or rectangle) thin wall tubes to bend without getting concave. I have not used a mandrel though. Never seen one, but it should be possible. If I want to have a...

If you already have one, it doesn't look like a difficult mold.

wire

I use 1/8" steel. Galvanized, if I can find it. Had luck with 8 gauge fence wire. Stainless wire will make your panel take on any corrosion effects....

Temporary adhesive

I like Crystalbond 555 because the residue comes off with water. I heat the part with a heat gun and put the Crystalbond on like a color crayon. Then put it on the substrate. You can't use water...

TIG size

I use .o4" or 1/16" tungsten. More likely use the .o4" for tacking. I don't see much variation on gas cup unless I am outside, or by a draft inside. Typically a 3/8" opening. I use bigger...

1/8" shrink

I have bent 1/8"x 1.5x1.5 (6063)on a hand shrinker. Big radius though. I had to modify the jaws to get them to open up enough. I did it cold, but I think a little heat might make it work on a...

Steel rod

When Peter came to Dan Pates, he also had a 5/8" steel rod bent like a slapper. Easy to make and very useful.

Cleaning options

A couple options for cleaning airplane parts. I have used ultrasonics baths, mostly flux removal on brazed pitot tubes. Most machines are 40 kHz, which have lots of power, but the 100kHz machines...

Thanks for the explanation. I figured there was a lot of practice put into that. One trick I have found with engine turning is to use a guide to keep the rows straight but do the spacing by eye. ...

This is messy and you have to be careful, but hot cooking oil can be used to soften plastic enough for forming. The heat is very uniform. If you make a box with the plastic sheet on the bottom, the...
