Let me just say that even as i post this, I have decided to try it, but i am curious as to what other members might think, especially an engineer's prospective,and not just a professional, but a backyard homebrewer with experience in fabrication as well.
I have an '86 giant rs930(my favorite commuter) that i am in progress of upgrading to disc brakes. The progress is going well and I have completed the rear, but i am having budget issues, so I have considered another option which i feel would be sufficient to complete. In order to do the front, I was going to need to change the fork, and since there is only a few forks that would fit, my options are limited, as well as i would need to spend excessive time and money to acquire a new headset, stem, spacers and dialing in the fit. I have my setup dialed in perfectly so i would rather not mess with it. I first considered having a metal fabrication shop welding the tabs to my existing fork, and though i think this would be best, then there would be large paint repair area i love the color of my bike( deep plum) and the paint is in excellent condition so i dont wwant to deal with matching or changing the color.

Here is the plan. Having some experience with Epoxy, i am considering taking the adapter attached, and epoxying it to the fork, which is something i could do myself, there would be little down time, and if I f*** it up, then no harm, no serious money blown, and save until i can change the fork. I am pretty comfortable with epoxying and have made some serious repairs with it, so i have high confidence, but lets hear from all you experts out there as to concerns about this modification.
