I understand your point, and i don't think just anybody should try this, but at the same time I don't think its rocket science either, plus I'm not expecting my bicycles brakes to be the almighty forcefield. I never expect to do anything but slow down with bike brakes, not stop on a dime. If i wanted anti-lock systems with airbags, I would drive to work, which leads me to the point that to bicycle commute in a big city, one has to be a bit crazy anyway, not to mention I've been a big guy all my life, riding bikes with mediocre to crappy brakes on all my bikes, so It's been a real treat to even have disc brakes in the rear, just because they slow down so well, I think other big riders would agree. Either way, If you have to lock up your brakes, whatever kind they are, you are having a bad day.


With that being said, I am also very confident in my ability to build and make structural repairs, which is why i thought of the idea in the first place. I know this stuff is strong, I have used it previously for many things, even to replace metal that required drilling and tapping to receive bolts. I guess i wasn't asking whether or not that part could or should be done, that part i have made up my mind, I know it can.

Let me re-phrase the question, and put it to someone who is or has worked with a framebuilder in a similar situation. Is it feasible to add disc tabs to a cro-moly fork that didn't have them is the first place? Is there any concern with the fork itself, and if you weld/braze will the heat damage the fork( i considered welding it myself, but if there are special concerns, i may not)? I will test the spacing myslef. I have a disc ready wheel already and 6" rotor, so i will know shortly whether it all will fit.
