I have an 86 vt700 shadow. I'm going to hardtail it after my trip next week so i can put a king/queen seat on it. The shocks that are on it now are so stiff it may as well be hard tail anyway. Most of the people seem to half ass and just use the stock swing arm with struts or they they weld upper tubes to the non diff side of the swing arm and bolt the other side to the diff, leaving the swing arm. I don't want to do that. I want to get rid of the swing arm and all the weight and parts that comes with it. I know how i want to do it, but i need a flange for the diff to bolt to. Where could I go to have a flange cut out for me? Would it be really pricey? The other option is to cut the flange off of the swing arm the diff bolts to and then weld tabs to the top and bottom to hold my frame tubes. I'd rather have a new flange though.

I want the drive shaft exposed. Basically, i'm going to do this: http://i1036.photobucket.com/albums/a444/cshaw07/Hardtail_2_web_zpsw880qvwd.jpg (http://s1036.photobucket.com/user/cshaw07/media/Hardtail_2_web_zpsw880qvwd.jpg.html)

What would you guys do? Weld tabs to old flange for frame to weld to, or find somewhere to cut a new flange with tabs? Where would I even look for a place to do that?

Wouldn't be hard to do at all or expensive for that matter, find somebody in your area who does waterjetting give them a sketch of what you want and you will have it the next day. i recommend having 2 pcs made just in case. Good luck.

if you have the ability to hard tail the frame, you could probably do something like that your self

1/4 inch plate, a hole saw, drill and a grinder and you could turn up something that looks good in an afternoon.

pick up a cheap set of transfer punches like these (http://www.harborfreight.com/28-piece-transfer-punch-set-3577.html) and use the flange off the swing arm as a template to get the hole position right

I'd be generous with lubricant on the hole saw and avoid letting it get hot. A ghetto transfer punch can be made by grinding a point on the butt end of a drill bit whose shank fits your desired hole. You aren't beating it to death doing a transfer (since you'll follow up with a center punch before drilling a pilot hole with a small bit) so a tap on the pointy end of the drill pit with a hunk of something "not steel" won't hurt it.

If you buy anything for the job, a machinist "center drill" is a fine invention which doesn't walk like a conventional drill does even when held in a milling machine let alone a drill press or hand drill.
Center drills are fucking wonderful. Google "machinist center drill" for images.

This guy is spot on^^^

Buy a #2 center drill. I use them at work all the time and they'll catch the webbing of just about any size drill bit you need

I used 3/8" plate and I'd avoid 1/4". The plate was cut using a bi-metal hole saw, an angle grinder and a bandsaw.

That's a nice frame man. Badass. Did you just weld the frame tubes straight to the flange?

Yes I did. http://www.chopcult.com/uploads_user/8000/7770/95998.jpg
