Nifty tool there - that was some good thinking. I appreciate the offer, I think that I will set up a jig and run a trial with the old turcite to see if the epoxy will bond correctly. And thank you for following up on that spreader tool.
For some reason, the bond that failed on the gibs was on the cast side. Took a closer look and realized that every turcite gib had failed. ... leads me to believe that fadal's surface finish method is to blame.. The arbitrary, rough indention from a blasted abrasive aught to be conducive to a stronger bond.
Here is the process that I am going to experiment with: (let me know if y'all have any suggestions)
Cast prep:
1) heat up cast to remove impregnated oil.
2) blast with fine sand abrasive
3) blow off and wipe down with acetone
Turcite prep:
1) scrape old epoxy off surface
2) sand
3) blow particals out, wash off with water?
4) let dry
Glue jig:
Build a jig that will both block the turcite in place to prevent creeping, and also allow me to apply even pressure.
Epoxy:
