What to do about raised binding holes on used skis?

[mdf]

My son bought some used enforcers and, separately, some griffon bindings. I brought my binding drill bits and some hole plugs so we are can mount them while I am visiting. But I noticed the old binding holes are raised above the top sheet, as you would get with no countersink or too much torque.

So what do we do about that before we mount the new bindings?
Pound them down before inserting the plugs? Sand them down (unlikely )? Ignore them?

Thanks for any advice....

Not sure what our shop rats are going to say, but locally....plug the hole, scrape off the works with a chisel and mount your new bindings.

Sounds like they didn't tap them and they mushroomed. Plug them and maybe take a dremel (with a ball adaptor) to them to get them flat. If he is going to be up in our neck of the woods, I can help him out.

A sharp 1/2" wood chisel will usually take the raised bit clean off, freehand no mallet. A razor can work but is more fussy than the chisel.

A 4" razor scraper will take care of it in about 30 sec.

So no issue with losing waterproof-ness by removing the raised part?

 

[Doug Briggs]

Use waterproof glue when you put the plugs in. Take a panzer or a Sure-Form to remove the excess material flush with the topsheet. Moisture penetration shouldn't be an issue even if some topsheet is removed. The materials exposed ought to be waterproof. If a wood core was raised in the 'volcanoed' hole so that it is visible after removing the excess, then you have bigger concerns than waterproofness.

You need the topsheet flat for the new mount to be flush with the topsheet. You don't want the binding 'standing on stilts' from the old, volcanoed holes.

Mike, I use to worry about waterproofness when mounting and remounting skis for years, but now, I've come the believe that the skis will wear out and be rock skis long before any core rot sets in. I still do my beast, but don't worry enough to be too finicky. Besides, Serpula lacrymans was most likely baked out during the bake and press. Have a beer while mounting, and don't fret it. It'll be alright no matter what you do. Take @cantunamunch advice and use a chisel to knock down those nubs.

Stanley Surform: https://www.homedepot.com/p/Stanley-6-in-Pocket-Surform-Plane-21-399/202262007. Works like a charm. Hole plugs with glue. Pound 'em in. Surform to smooth things out.

All done. Used a chisel. Wooden plugs for the overlapping holes, plastic for the others. Drill press then tap for the holes

That's, uh, quite a workshop you've got there.

Damn millennials, always sitting down on the job.

Nice drill press.

What’s with the rei tag on those skis ?
You gotta drill through the ptex to warrant that badge of shame

Nice forklift

There was one pre-existing plugged hole from a mis-drill on the old bindings..

Ya know this isn’t rocket science ...
But I continue to be amazed by what I see
