Ah well...fair enough and good luck. I've seen similar ideas fail, fortunately never in a catastrophic way just disappointing. Worst case you'll have a chance to buy a heavier and even less appropriate xc bike. Keep an eye out for the old kona stabs!

If i could raise the $1500ish this would be my next xc bike, from what I gather its the short travel version, maybe only 10 pound heavier than the cove. Life would be good then, no, perfect.

Wearing a dress works for Dozer, so yeah go for it! Just remember pics or it didn't happen.

What grade of aluminium is it? Some grades are self-tempering and will return to close to initial strength after a period of weeks (where it's wiser to stay off the bike). More common is 6000 series (e.g. 6061) that definitely need heat treating post weld or the weld will stay a major weak point.

Unfortunately it is 6061so should be heat treated but finances mean that is not happening. I will take the chance as it has been welded gusset to gusset.
Just a thought, would a gas ceramic kiln put to the right temperature do the job. I may have access to one of those

I was curious about this, so I looked it up. The temperature is actually not that high; around 176deg C.
Intense do their own heat treatment it in-house and there is a great article on their process here.

Was thinking the same thing.
You can heat treat that frame in your oven or enclosed bbq...maybe.

If it's already been heat treated you would have to anneal the frame first then start the heat treatment process again. Otherwise you will end up with a frame that's so brittle it will crack everywhere. I haven't had indepth experience with it but I know with heating and quenching, times and temp are critical, get it all wrong the frame will be ruined and most likely look like a banana.

in the end I think I will just ride it until catastrophic failure, shall post photos of teeth before and after if failure happens. If it does farkup I think it would just crack and not fail, its not like I am joshie bendem

A good welder will know what to do, I wouldn't bother with the heat treatment.
I'm sure it'll be sweet.
As much sh1t as he used to get, he's pretty much responsible for redbull rampage as it is today. I think organisers were keen regardless, but he took them out to his riding spots where they first held it, and advised the lines to use. Mad b@stard.

Pretty piece of tig welding, but based on experience of having done a couple of emergency tig fixes at races in years gone by, that will crack again, on the edge of the new weld. Grip would have gussetted it and it would last forever. I recommend you keep a close eye on it, I've seen a head tube let go, and was very glad I was not the rider involved.

Some of the most amazing shit ever done on a bike.
I think so. The front end coming round and attacking your face isn't cool.
