LamafamaThere's plenty of reasons to use a 72 hour water proof epoxy over wood glue. A lot of rando racers will use it to reduce the risk of a pull out and the same goes for using inserts. I've used expoy on the binding screws on some of my skis as the core has been dusty, using expoy and wire wool fills the void and reduces the risk of a spinner or pull out. I judge what to use based on the ski / its use.
alright true, there are occasional reasons why you may want to use epoxy, but given the original post, i can not see any reason why you would use epoxy in that particular mount (and frankly for most mounts, I mount bindings frequently and have never had a situation where I've needed to use epoxy on a mount, i would only if a customer specifically asked for epoxy in the holes). if i were concerned about the structural integrity of the core or threads on a previously threaded hole, i would helicoil before i filled the hole with expoxy and wire wool
also i have never heard of a shop using a 72 hour set epoxy. i have never used anything more than 24 hour set, nor heard of other shops using anything more than 24 hour set. even a full delam can be fixed with a 24 hour epoxy perfectly fine, 72 hour would be just unnecessary wait time for any shop.
