I got the frame back yesterday so here it is in this new post rather than hi-jacking Crackers thread further. I think the fabrication turned out good and I'm happy with how the top of the Y is reinforced. I'm not real happy with how the welds look though, so I might look into fixing that after run it for a bit and do a tear down again. It was 200 bucks for all the work so I can't bitch that much. If anyone is interested in my engine jig, I'm probably going to build a few of them next month when I get the tubing for the swingarm rather than cut up expesive OEM collars.

What thickness of material did he use to box in the top of the Y? I think I like that better than the bat wings.
Good job.
A guy of by Lake Elsinore did it for me and he's been welding longer than I've been around. I kidded him about how they looked and all he said is
" this wasn't easy and I should have charged you alot more" LOL He used 1/8 thick billet for the Y and pretty much copied Shanmans motor mounts.
If this does not hold I'm going to go with the whole new Y and heat treated route ,so we'll see. As Bob said, this shit is pretty hard to weld so that's why I didn't try it with my limited TIG welding skills.

Talk to Teemtrouble (Mike) about the heat treating. I would bet that he'd suggest that you have it done now. The guy really knows his stuff.

Tell me this bike doesn't see any abuse. I dare you.
That bike doesn't see any abuse. You should have double-dared me.
BTW, I'm not saying that this stuff is rocket science, but if it lessons the chances of failure, why not do it? Also, I have a lot of respect for Mike's opinions on the subject.

Being completely ignorant on the subject of metallurgy, I would totally have that conversation/education and really should butt out of this one.

Trust me, I'm as ignorant on the subject as most. All I know is what he's shared with me. However, after seeing his build, talking to him on the phone for a good while and given his experience, if he told me this needed to be heat treated, it would get heat treated.
I think it looks great. I have the box sections made for mine, and did mine the same way. I used .080 and used .125 DOM tube cut in half and pressed the aluminum into it to make a half moon saddle to box it in with (pics to come soon). I used a 1 piece inner support to close it out where you used a 2 piece section. Great job
first three gen. 3 headstays done (minus front hole to be match-drilled). Mike, one of these is yours (shoot me an e-mail)...the other two are for a friend of Bob's and Billy. I can make more if there is a need.
