Advice on fixing serious base damage, pl.

post #1 of 8
Thread Starter 
Hi all,
I don't have any professional ski tuning shop/person around. (I could wait for the next trip to major ski location in Alps, but would rather have the skis ready before).
Can anyone recommend a sequence of steps to fix the damage - see the pictures below.
I have edge tuning device with several angle options w. 0.5 step, base guide, and base candles.
Although the edge is not destroyed, it will need a 're-shaping'.
What angles do I need to set (the skis are K2 Outlaw)?
Thanx a bunch!
Paul

I wouldn't ski these. They need a weld. You're worried about edge angles?. Un hunh. Sure..you can lay the P/Tex to them. Scrape it. It won't stick to the core or the edge. It will probablly ALL pull out. When? Maybe a few minutes..then grab the edge and toast the ski. I dunno..it might last a bit..then ya gotta keep watching it..worrying about it. Laying the P tex to it could case the guy fixing it to not see/look for the extent of the damage. They're gonna have to clean all your P/tex work out anyway. I would not even bother with the P/Tex if you were worried about edge angles.

Here are some base repair ideas that may help.

So I understand it's better rest it and bring to an expert (most likely the next season for me ).
If it means to wait for the next season, what would be the best way to 'conserve' the base till then? (I usually put thick layer of hot wax at the end of the season)?

Leave it alone. Anything you do now can make the repair harder.

This looks like it needs a patch not a ptex job. A patch is done by a competent shop and involves cutting out the damaged base and applying a patch made from base material using epoxy.

This will fix the core shot and then you get a base grind, then fix the other less serious areas.

I did the following job in my garage and then ook to a shop for a base grind.

1. http://users.eastlink.ca/~mhoyt/base...on_removed.JPG
In this pic I had chiselled out all the bad area (it was a lareg core shot)

2. http://users.eastlink.ca/~mhoyt/base..._for_epoxy.jpg
In this I have teh prepped area cutou, the patch shaped and all ready for epoxy

3. http://users.eastlink.ca/~mhoyt/base...tch_curing.jpg
Here the patch is in place and ski wrapped in plastic wrap so epoxy does not stick to other things like clamps, etc. Once epoxy and patch applied I place metal scraper over base edge and clamp in vise for 1 day

4. http://users.eastlink.ca/~mhoyt/base...patch_done.JPG
Done. After removing plastic wrap I used panzer file to take down excess and then had shop do base grind. Then I did a tune and wax.

I have done this a number of times sometimes even without teh base grind. Teh patch shown here is very large and may eventually fall out.

Where do you get the base material? The base on my skis is separating at the edges. They're quite old and due for replacement next year anyway, but I'd like to get thru the rest of this season with them and maybe have them around as a backup for the future. I'm guessing I'd need to glue in a strip about a quarter-inch wide and three inches long. Also, what brand of glue did you use, and from what source?

Base Repair Sheets

We have some base repair sheets. I'm not sure the best glue to recommend though......

It seems that welding a 1/4" x 3" strip would be easier and work better than gluing thin strips.
