What I found is that tacking with o/a on alloy is way harder than tacking with tig!   Also when I make my tacks I try to keep them smaller, just dab a little bit of filler rod in there if needed.  I used 1/16th rod.  Large tacks are hard to deal with when you come to doing the final welding.   Make sure all of your joints are tight before trying to do the final welding, no gaps. I'm not criticizing just pointing out what I have found to make things easier.  Keep at it I look forward to seeing the finished item :)

Wouldn't mind if you were criticizing, it's constructive and I'm just happy to get advice. Not many people are O/a welding anymore, so glad I found some resources. The distortion and gaps are why I stopped, need to do a little hammer work to bring the joints back together. Thanks for the tips!

Make sure your parts are a perfect fit with no gaps before you start tacking anything.  In my tank thread you can see how my parts fit together before even thinking about tacking anything.  Keep at it, you will get a real sense of achievement when you are done :)

What torch are yall using? ive had some luck o/a welding aluminum with henrob 2000 torch later called a cobra 2000 I believe. about 3 lbs. line pressure oxy and 3 lbs. acetylene iirc. its been a few years since ive had it out. I generally stick with tig, but I was impressed by how well it worked.

Its an old victor torch set up. I've looked at the henrob, but I think it would be overkill for my occasional welding. I'm running 2 psi on both, and that seems to be working well.

The torch and set up was passed down to me from my great uncle. They had not been used in years when I first got them, and without knowing better I traded in the tanks hooked them up, and had leaks at every joint. luckily I noticed before adding oxygen to the mix. After that I inspected all the joints, cleaned everything up, and read a lot before trying to use them again.

Seat Progress





Slow going of setting up torch, lighting, welding, turning off torch, grinding, brushing, cleaning, flux, setup torch, lighting, welding...
over and over. Still have 1 pin hole and 1 crack, and lots of filing and sanding to do.

Round three of welding, grinding, sanding, and now throw in some polish. Pretty happy with the results on my first aluminum welding project though.

Lovely work!
You've inspired me to pull the cover off Tidler and re-work my brake pedal I've been meaning to do for ages!

Show some pics, tried to see what Tidler is, but didn't find a thread.
