View Full Version : Big (for me) aluminum welding project.

I built this 25-gallon catch-pan for changing the oil in large trucks. It's made of 1/4" aluminum sheet with some 4" x 1" channel for the base. I TIG-welded all fifteen feet of the seams, and there were no leaks. I had the Miller Synchrowave 250 running at 160-180 amps for most of the welding.

The cover has a frame of 1 1/4" aluminum angle covered with 1/16" sheet. I didn't want to risk having the welds distort the frame, so I used pop-rivets to secure the sheet.

Dang Roger.. got some time on your hands? I'd tied a chain to it to rescue it from under a truck too. Purty as it is, around here someone would steal it.

I got a big plastic truck drain catch pan for $9 at a truck stop. It has a nipple on one end and a cap.. you lift it take the cap off and pour it off into containers to dispose of. (of course I lost the lid long ago)

OKAY.. now you got it built.. do some engine turning on it, then shoot it with clear coat.. make it BUUUTIEAFUL... A rubber disc on a side grinder makes a excellent damascene turner.

Very nice,I wouldn't be worried about some one stealing it as I would somebody running over it.

Wow, very impressive!

You need to get the Zep-A-Lume (aluminum chemical polisher) that Doc posted on the other thread, and make it reall shiny ;)

Maybe somebody could photoshop it so we could see what it would look like polished to a mirror finish like this:

That looks like an extra 300, but is it an S or L?

Or maybe an edge 540?

Shiny is easy.. if you got flat and unscratched to start with..

Simichrome and a brown paper bag, not sure how it works, but rub it till the bag is black and the metal looks like chrome..

Damascene is what I adore.. bright.. like a shiny thing.. sparkly.. OOOOHHHHH AWWWWWW..
