While I had the motor out of my stock 71 triumph, I decided to weld up another kickstand bracket. I made one last week out of a replacement block for another frame size, but I wasn't happy with it, so I decided to replace it with one of these ebay jobs... I'm pretty new to welding, and my skills aren't quite payin' the bills yet, but everything was going pretty well till I went to button up the underside. I burned a pretty good sized hole into the frame. I turned the voltage down, and welded the hole in the best I could and even went a little further out past that area. I think the tube was probably worn a little thin from grinding the old stuff off. There is probably still a bit of a hole behind the plate that I weled on. It cleaded up pretty nice after all was said and done, but I'm nervouse about it. I figure since it's in the location of the the old bracket, and betweeen the two mounting points of the engine, it should be okay, but wanted to get some opinions first. I'd show a pic, but there's really nothing to see... it just looks like a normal kicker mount.

I've got the motor back in now, but I havent' wired or plumbed it yet, so now's the time to do someting, if I'm gonna do it.

Thanks

Personally, I would consider making a patch piece and welding in place over the hole. It would be stronger than just filling with weld, and even if there is really little to worry about, why take chances.

I second that vote if you haven't done so already. The motor will support the area, but I would say for peace of mind it should be done. You'll probably never see it once things are bolted back together anyway.

Do you think patch, like cut out that whole section of tube and replace? or patch, like fill in just the hole with a "hole-sized" piece of tube?
The idea is to support the surrounding area of the hole. I would think if you had it large enough to just get a good penatrated weld all around the hole, (without burning another hole!) it should do the ticket. Replacing the tube would of course be ideal, but you are talking a HUGE undertaking! I replaced the front down-tubes in my frame because the same thing happened to me and it was extremely difficult and I had to special order the materials because it's an odd size. Cost me $50 for a 12-foot stick of thick walled tubing. Stick to a properly made and welded support patch. Watch your welding settings. If you can't do it without burning through, take it to a local welder to have it done.

Something else you may consider, if the tubing is really worn on the bottom, you may want to weld half a tube to the bottom of the frame. Problem becomes getting around the mounting lugs that are in the frame.

How large of a hole are we talking here? We should be asking that I guess...

I used the exact same one. I wouldn't worry too much if you actually have it welded together in the same manner as your drawing. I agree with sojerscraper also about the weekest link saying. Just be sure that your getting good penatration on those welds! You don't want to come out of the store and find your scoot laying on it's side. :eek:

Thanks for the advice! Especially about the fat chicks. Yeah, my welding is getting better, but I still have a lot of trial and error to get past. I tend to over do it to just in case I'm not getting the penetration I should. That seems to just end up causing more problems though, like this one.

Thanks again!
