Core Shots and Base Welds

post #1 of 6
Thread Starter 
I have gone back to maintaining my older, ski anywhere, skis myself. These skis regularly get core shots, especially on early season trips where there is reasonable off-piste snow without a deep base. It was suggested to me that instead of taking them in for a base weld (usually associated with a grind) I do my own repair by coating the exposed core with a thin coat of 1-drop glue and then p-texing before it dries. I have done this a few times with some reasonable success.

Anyone else have any experience with this or other do-it-yourself techniques for core shots??

I've found the best thing for core shots is co-polymer. You can buy it in black or clear. Buying a role is a little expensive, but it will last a long time and I think it is the best way to fix core shots. P-tex just won't stick to the core material. I guess the glue method might work since I have also just used 24 hour epxy in the past with good results if you don't care about the colour. Don't even think about the 5 minute stuff. With both these methods you should be able to make it smooth with a metal scraper and some fine sand paper; and not need a base grind.

Good Luck!

24 hour epoxy and a pre-cut Dutchman of cold ptex works best for really, really thin abused bases where you'd have trouble getting co-polymer to adhere to the base surrounding the hole. EDIT: prep with sandpaper and rinse with isopropanol then acetone.
Of course, the repair lasts longer than the rest of the base as water gets in and bubbles things up. . .

Epoxy impregnated p-tex. Wintersteiger sells it by the spool.

Let it cool and cure before shaving it down.

You can't miss.

skidoc is right, I have used the epoxy p-tex. Just take your time and do it right. Don't try and fill the void at one time if it's a big shot. My G3's have a 3/8" wide by 2" long edge shot I have had two shops try and fill it. I have it almost filled, I have skied it then fill some more. It seems it dosen't like to hold normall p-tex. I'll get it filled some day. I hope you realize that not all shot's make the ski no good. For most of us, we don't need perfect bases.

I have had my friend the X WC tuner look at it after I 've been filling it and he said "I'm getting there. Just a few more times".

Tip, I try to preheat the area before I drop the p-tex in. Becareful not to melt the ski. My G3's have a burn spot on the side. Just blow the fire out, it dosen't matter.

WC Tuner


Just curious. What's your friends name who tuned at the World Cup level?

If he worked with the US Ski Team I'm sure I know him.

Does he work in a shop?

What athletes did he prepare skis for?

I ask because there's not too many of us around.
