:: View topic - how much epoxy do you need for one pair?

how much epoxy do you use for layup?

On the last pair of skis, we used about 1250 grams of epoxy with about 175 grams left over. Some of it get squeezed out during pressing and it will also change based on the epoxy that you use.

thanks!

About how much epoxy is 1250 grams by volume? Thanks!

Opps, might have answered my own question.

1 ounce = 28.3495231 grams (right?)

Well you know what they say, nice try but no cigar.

Did anybody try those inserts for a ski:

http://www.rampa.de/rampa/pdfs/s8-a.pdf

They are widely available in Europe (most Hardware Stores).

What do you think - give them a try?

I have seen them in a tools-shop few weeks ago. I suppose they are the ones used to fit a wear-out hole in the skis.

I suppose that if the wood-core is hard enough and if they are well placed (putting some epoxy) they should work. I was thinking to give a try.

the good part is you can put them in after the ski is finished. but you would have to make shure you don't screw the M6/5 bolts too far, or it will delaminate the base.

Yes that's the thing i'm thinking off - i would like to put the into the finished ski to make a variable mounting position possible. The ones with M4 thread that are only 8mm long seem to be the right thing!?

Well, you can cut (grind) them if they are too long.

M4 is too weak I think. you should just cut M6 to length

M6? - as far as i remember the binding is mounted with 8 x 4,5mm wood screws!? Maybe we're talking about different bindings i ment regular downhill bindings not telemark...

hmmm. I just imagine that the wider the inserts, the better they grip. Isn't M4 screws a littebit thin?

M6 (1/4-20 for english) is pretty much the standard for snowboard bindings. i think K2 uses M5 in their tele skis and Line either uses M5 or M6 for their reactors. i wouldn't recommend going below an M5.

Ok - i agree M5 should be a good selection. Wider inserts definetly have more contact to the ski.

Are all you Kam's still purchasing edge metal from Snowboardmaterials.com? Is there another source? I have not yet called SBM.com but I've read ski companie's brag sheets that tout thicker harder "rockwell steel" edges. Can better edge materail be had than is available through SBM.com?

I see the earlier post re: VDS referring to SBM.com. Is that still the best source? I dug through the McMaster's site & don't have the product knowlege to find the correct item on their site. Help?

Thx -Jed

Hey Hose-man,

Kelvin ordered a bundle of edge material from CDW a while ago and we're still using it. They have the same dimensions as the Snowboardmaterials.com one but have a coating to prevent rust. Big Kam and Kelvin work in the PNW where rusty edges are a problem so it really helps out.

As for the larger edges, pretty much any edge supplier will make whatever you want within reasonable dimensions. The only problem is that they require a minimum amount due to the custom operation. I think CDW's minumum was about 120 edges that were 84" long (Kelvin?).

I think VDS is just a fancy term that manufacturers for mean rubber strips. If you go www.mcmaster.com just enter "rubber" into the search engine and you'll see a page with a "strips" link. Just click on that and select from the desired specs: width, length, thickness. You can also order in "sheets" form which might be a good size to make damping enhanced tipspacers (what Karhu/Line uses in their skis).

I don't remember the exact minimum order for custom edges, but it was alot. Something like 500 lbs. Unless you plan on making about 500 skis, then it is not really worth it to get custom edges. The following places will take a CAD file and make edges for you. I don't know their min order, but it is probably alot.

I'm trying to find more info on the VDS rubber. I think it is some sort of urethane rubber and it may be treated for better bonding.

Profiles is only 2.5 hours from my house.... I wonder if I could see what they could do to help me out some. I'll submit a 'contact' form to them!!

I talked to lindsey at SBM.com and I've decided just to purchase the edges from him. He importes them from one of the euro ski makers. I will get the 84" sandblasted ones.

above "Guest" is me.

As there is lots of different rubber sorts: polyurethane rubber, styrol butadien rubber, latex, silicone rubber,... what's the best to use for dampening my ride and which material bonds best with epoxy?

I am looking for more info on edge manufacturing or ordering. I was wondering who CDW was?
