A couple of questions related to the original post:

- is there any reason I can NOT braze / tig weld a rack boss on to a front fork?
example: REAR RACK BOSS LARGE (MTB) :: SMALL PARTS :: BRAZON/SMALL PARTS :: Nova Cycles Supply Inc.

I would prefer not to drill and press in / braze a standard front rack boss:
example: LOW RIDER BOSS :: LOWRIDER BOSSES :: RACK :: STEEL SMALL PARTS :: BRAZON/SMALL PARTS :: Nova Cycles Supply Inc.

Mainly I don't like the idea of drilling a fork that was not originally designed for the boss. I'm viewing that hole I just drilled a weakening the whole structure.
Also - any reason I cannot tig weld these bosses on?
I don't know how to braze or tig weld - so both cases are a learning experience for me.
