I just mounted my daughter's new skis. I put Marker M4 bindings on them. I drilled the ski in the correct places with a Wintersteiger 3.5mm x 7mm bit. I reamed the holes a little bit with a countersink. Then, I hand-drove the supplied screws through the bindings, into the ski while exerting significant downward force. These are wood-core skis.
I stopped turning the screws when they wouldn't turn without excessive torque. The end result is that the topsheets seem to have swelled up right around the screw holes so that the binding is in contact with the swelled areas, but not the whole topsheet. I can probably slide a business card under the toepiece.
So, what should I do? I could probably leave them, as my daughter isn't too heavy. Or, I could remove the bindings and plane off the swollen areas of topsheet. If I do that, would I be weakening the setup? I've read that the topsheet provides much of the resistance to pull-out. I could ream out the underside of the binding holes, but that sounds like a bad idea.
Thanks in advance for any advice.
