I’ve used CA glue (cyanoacrylate glue) to hold guide blocks on oak without a problem. There’s a little gunk left behind and a couple torn fibers, but no more than would come off during finish prep. Rather than chiseling off the block, I give it a smart rap with a hammer. CA glues fracture under sudden shocks. Can’t remember if I’ve tried this with cherry.
A number of CA glues have accelerants; Titebond, for example. It’s a separate purchase, though. It’s more of an “instant freeze” than an accelerant.
I think Krazy glue is CA, but am not 100% sure.
