My experience with epoxies, in particular those with a long open time like T-88 is they leech/soak into open pores, wood grain, abrasions etc. every bit a well, if not better than titebond- type glues. And I have read in articles- posted by RAD I think- that glue starvation is pretty much a non-issue, so clamp away tightly. The bonding/curing occurs at a molecular level so a thick layer of epoxy is not necessary for a good bond. Therefore tight joinery equals nearly invisible glue lines. Another thing I have discovered through testing is that too much hardener in the mix can leave the cure soft, and just a little less hardener than resin will be yield a very hard cure. That sounded counter-intuitive to me, but when i posted the results of my experiments a year or so ago, I had quite a bit of feedback confirming that finding as normal.
T-88 is good stuff.
