Preparation for bonding involved filing off a small patch of the powder coat and cleaning the area thoroughly with brake cleaner. That done and the epoxy applied, I must have spent half an hour fiddling about trying to get the braze-on in exactly the right position and adding a supporting bead (just like you would do if brazing). At one point the wretched thing slipped completely out of position, making it absolutely essential I located the bottle of isopropyl alcohol I had failed to locate before I started (JB Weld buys you that time). With the mess cleaned up, the second attempt was successful and I left the epoxy to cure overnight and most of the following day. Whilst it cured, the triangle, work bench and positioning jigs had to remain completely untouched by human hand or feline paw. But eventually the wait was over, and the result was purrfect. Note that the machine screw that secures the pulley block is partially removed from the right-hand block.
