The gluing went well. First I cleaned all parts with mineral spirits to remove any oils. I then put a small bead in the inside corner of the v rail. The small tip on the glue nozzle made that rather easy. The glue is quite clear and hard to see, so make sure you have a lot of light. I then pressed the v rail onto the extrusion. The glue is supposed to have a 75 second hardening time. I found that it grabbed almost instantly, but the excess that squeezed out took about an hour to fully cure. I got some on my fingers which cured instantly. This got a few finger prints on the parts.
I let it set for over an hour, but I did not need to clamp it. After curing I was able to clean off any excess glue fingerprints by scraping my fingernail access it. The bond is quite strong I pulled very hard on all parts and it did not come apart.
I only did one of the three pieces so I could try something different on each. I think the next one, I will put the bead on the wider part of the v rail rather than the inside corner. As I install it, I will slide it into place to spread the glue over a larger area and be less likely to squeeze any out and get it on my fingers. It might make it cover more area too. The bead size might be easier to see and control.
The new 2x laser only puts v rail where needed. This reduces the amount needed. I cut the r vail with a abrasive cutoff wheel. It cuts it in about 5 seconds, but leaves a little burr that you need to be sure to remove so it does not affect the fit. It also leaves a bit of a heat mark, but barely noticeable. This is one of the Y rails.
