Core shot help

Before you tell me to take it to a shop…. I already took it to 2 shops. Plus I’m stubborn

One of them would need to send it to a speciality shop down the road.. and the other would charge around $140 alone in labor for 2 hours.

I’ve tried fixing it about 4 times now with no success.

So of course, I come to Newschoolers with a broken heart and tearful eyes… looking for help from my fellow ski bums.

1st try - No epoxy, P-Tex wasn’t hot enough. Oxidizing flame = not sticking to base. Base repair cracked as it was drying.

2nd try - Cleaned up edges a bit more, tried using propane torch. Repair spot cracked while it was drying. P-Tex chipped away with barely any effort.

3rd try - Applied epoxy on base first. Tried again. Forgot to wet epoxy, epoxy burnt and bubbled. 3rd attempt = fail :-(

4th try - Cleaned base with alcohol. Applied epoxy. Cleaned base again. Wet epoxy base so it wouldn’t sizzle. Burnt P-Tex with propane torch until it was dripping quickly. Base repair cracked AGAIN.

So now I’m wondering why I can’t just glob a shit load of epoxy in and call it a day? Will atleast keep water from getting to the base no?

I miss my park skis :(( My K2s are huge and I can barely whip them around in the park. I love these skis so much I refuse to let em go so easily lol

Yeah that's an epoxy. What you should do tho is get an exacto knife and trim the damaged base. Clean it up a bit and then use machinable epoxy if you can. you'll need to properly base grind it after and it hopefully should work

A shop wanted $140 to do a little base weld on that? What shop?

When you laid the ptex did you heat up the area with a wax iron? That has helped me get good adherence with a big shot on my edge. Laid a bit of G Flex on the core and against the edge, kinda filled the hole up so the ptex is not super thick either.

Yea man… I know it’s not really a proper ski shop but MEC are the ones that charge $70/hr for labor. They’re like 5 minutes from my house tho lol so I gave it a shot.

Called another local ski shop just now and they’re estimate with a proper base grind is around $90-$100.

What’s this G Flex stuff you speak of? Does it come in small sheets? Is it a 2 part epoxy mix? Where do I buy it from?

And no I didn’t try heating up with my waxing iron first but I’ll give it a go !

Ok, I’m tempted to try this instead of P Tex again, seems like a lot less work lol

Why do you recommend machineable epoxy ?

G Flex is the best type of epoxy for ski repairs. They sell it all over...pretty much wherever there are boats to repair.

Idk that's what a coworker at my shop said. he did say regular is fine but machinable is better quality; whatever that means.
