Tapering bars for HIC

[Maz.]

So ive got a new oversized clamp, and i need to taper my old bars which are standard 1 1/4 crows so they can fit the oversizedclamp. I know the outside diameter of the hic tubing should be 34.9mm, but what should the inside diameter be so it can fit the hic shim on my fork thanks.

I believe it's 1 3/8 but that's just a guess.

Are you sure that's correct? so the tube would have to be 34.99mm od and 1.259" id?

 

[michaelchavez]

OD 1.375"
Wall 0.058"
ID 1.259"

Oh and also does anyone know hor far the taperr should overlap the bars?

 

[dpnelson31]

I want to say 2 inches or more would be just fine.

 

[Maz.]

Yeahyeah

 

[Ben.]

sorry for the bump, i didnt want to make a new thread. But would I use a tig or mig welder? and about a 2 inch overlap right? once again, i didnt want to make a new thread.

 

[Rob.]

Tig, you could do as much overlap as you want, i'd recommend more than 2 inches though

 

[Mr.H]

Overlap should be a minimum of 2 inches but 3 is better. Mig, tig (or brazing ) will work fine.
For extra strength drill a few holes in the oversized tube around half inch above where the standard tube finishes and puddle weld through the holes.
I have taper many set of bars like this and had no failures.
