Welding bearing hangers to round tubing

[xiodinc]

How should i go about welding a bearing hanger to a go kart?

I have this hanger: http://www.bmikarts.com/shop/images/Bearing-Hanger-400170-or-4001751224-9261.jpg

and i need to have it welded to round tubing. Where should i position it, and can i weld directly to the tubing, or would i need to weld some angle iron on it first?

Weld it parallel to the tubing, put a bead on both sides. center the hanger on the tubing and you should be fine.

that's one I did a while ago.

Ignore the angle it was there before I got the frame.

Alright, thanks for the help, that's exactly what i needed to know!

Should i add any extra support on the hanger, or does it stay on just fine? no bending or welds cracking.

You could weld on some angle so there is a flat surface and weld the hangers onto that. It would be stronger with the 2 flat surfaces overlapping and would be easier to get exact.

I have the exact same hangers on an old Coyote Enduro that I have, and what I did was get some 1" wide 1/8" thick steel strap, cut a half circle in one side, cut it to length, and weld that to the sides of the hanger. I put the hangers off to the inside since I am using bearing cassettes and welded them up. What it looks like is kind of like the picture of the bearing hanger that wall gator posted.

no matter what type of hanger you use.....IMO ..pre install,every thing on the axel(good finger tight will do) i.e. rear sprocket,brakes,bearings,hangers(you want them,to be able to slide(kinda).....turn kart up-side down,lay assembly(axel set up) on frame.....adjust every thing( left or right) MAKE SURE.AXEL is square.....re-check square!!!!!! tac one side.....check square...tack outher side.......check square....then weld away....and oh yeah..check square WALT

Yeah, before i start welding, im really going check and check again for it to be perfectly even. I think im going to be welding it just straight onto the round tubing. Ill post pictures of my progress. By the way, this is going on a Manco 415 kart.
