I've been trying to figure out the fiberglass repair method, but I'm having trouble getting screws into stuffed holes; the screws seem to bottom quickly against fiberglass in the bottom of the hole and spin really easily. Any advice? Do you really want to cram the hole full, or just have enough glass to hug the screw?

maybe somewhere between, I mix up a little FG & epoxy so its not too resin rich but the strands are still well wetted out
the idea is to run the screws into the hole with the FG & epoxy until they are just about to spin and then leave the epoxy to set,
after the epoxy sets you hopefully have made new threads and you can crank the screws down hardLee Lau - xxx-er is the laziest Asian canuck I know

Thanks! How much fg/epoxy do you usually get volcanoing out of the hole? I started down this road partially because some fks heel screws have nowhere for volcanoed material to go, and my heel had a bit of play owing to that material.

I cram as much epoxy & FG strands mixture as I can in the hole and run the screw in, it will be a soft gloppy mixture so volcanos are not really an issue
it sounds like the original mount had volcanos which didn't let the binding sit flat, i've heard the heels of this binding are more likely to pull out than bindings with rails where the mounting screws are farther apart
If you have a volcano from the 1st time the binding was mounted I would chamfer the top of the hole with a 3/8th drill rotated GENTLY by hand, a light chamfer ( just enough to countersink the hole & remove a bit of the top sheet ) will leave room for whatever epoxy/FG mixture wants to splooge out
once the epoxy cures you can take the screw out if you need to, the epoxy will likely be sticking to the screw so you might have to use a little heat on the screw head to break the bond but the threads in the hole should be renewed, for the final instal just use a little more epoxy and you should be able to crank the screws down hardLee Lau - xxx-er is the laziest Asian canuck I know

Thanks for the detailed description! I didn't hold out much hope that my current attempt would work, but sure enough I was able to really crank bindings down after the epoxy cured. I had used a very glass-heavy mixture, with fairly full holes, and I thought most of the screws were spinners when driving them in.
I used a small hand plane to remove volcanoes previously, and the heels feel much tighter on the skis than they did with my last mount. I think in the future I'll be drilling with a 4.1mm bit and tapping irrespective of ski label, then installing with epoxy. I think that will reduce the likelihood of spinners and of volcano issues under the bindings.
Thanks again, XXX-er, your instructions were hugely helpful.

OK so you just rebuilt the threads in the binding holes of your skis ... another happy camper eh
yeah so the reason you want that resin/fg mixture wetted out but mostly glass rich is that too much resin makes for weaker products and/or fixes
I just use any old 5/32nd bit cuz this is not rocket science, I don't use a tap, I do drill thru a wine bottle cork to limit drill penetration instead of drilling thru the bases
after drilling binding holes if I rotate a 3/8ths bit by hand to remove some chamfer from the hole I don't get volcano's,
those screws are now glued to the holes so if you ever need to take them out use heat on the screw heads BEFORE you strip the headsLee Lau - xxx-er is the laziest Asian canuck I know

whereas having Macgyvered all kinds of HW together for many yars, its probably a Thursday nite, I got a beverage(s) going, SO I look around the place at what I got that will work for 1 fix tonight
IME I always got epoxy, FG, BBQ sqewers kicking around so i don't have to go out or buy anything and shit is ready to go for the weekend
it has always held even on a tele mountLee Lau - xxx-er is the laziest Asian canuck I know

I don't have a picture on me, but my dedicated ski bit has a shoulder that is too flat to really countersink much. Also, the volcanos my first mount had were huge, (multiple millimeters for sure)- much more volume than the countersink would have removed. But maybe that was just the ski (Rossi black ops)?

Fixing a stripped hole on my wife’s nordic skis now.
Toothpicks cut in half and trim all tips off. Mix epoxy with picks, jam as many in the hole as you can. Take one last untrimmed pick, wipe it in epoxy and squeeze it in. Clean epoxy off top sheet. Let set 24 hours, trim to top sheet, redrill and mount.

I would have to fix something in deepest darkest interiour BC, many hrs from any parts, if it wasnt working when you left you gotta come back sooner than later to fix it , maybe a 6 hrs drive in horrendous conditions, so if I didnt have the part I would wander into a small town store looking for something that i could macgyver which could be safety pins/ crazy glue/paper clips/ 5min epoxy/ part of a kitchen gadget, the saw on my lockblade swiss army knife was an awesume tool for alterations to various things ... if you aint got it fake it til you make it

You know, a helicoil kit is pretty inexpensive and will last a lifetime.
