Vacuum pump

Gauging interest in a 1.1cfm Gast continuous run vacuum pump with nearly everything you’d need to vacuum press. Includes filter, exhaust dampers, vac gauge, braided vac hose, quick release attachment, and vac valve. I’d throw in a slightly used bag (18” x 9 ft tube)( no known holes) with sealers als...

Re: Pre-treating paulownia or balsa core

I'm pretty stoked on how well this set came out with the new core material. I'm not really sure that I even needed to pre-seal such a small amount of paulownia. For the next set I'm going with no seal to see what it does. It won't be a direct comparison because it is going in a much bigger ski, 188 ...

Re: Pre-treating paulownia or balsa core

I finally got to press these skis today. The finished ski with the paulownia core is ~9 oz lighter than the same ski with my traditional core. The ski is 182cm 135/108/123. The old cores ski weighs ~4.75 lbs per ski, the new core skis weigh 4lbs 3 oz per sk I used only 2 19mm strips of paulownia per...

Re: Pre-treating paulownia or balsa core

So I did pre-treat these stingers with some thin epoxy after taping out the other areas of the core that did not need to be treated. It seemed to soak in well. I applied a trickle of resin and scarped it in as well as wiped off any excess with a paper towel. Today I did a light sanding of the treate...

Yellow 1.3mm base

I have a roll of at least 25m of yellow 1.3mm crown base. My guess is it is 2001 grade but not sure. It is 10 years old but has been kept clean and dry. It would at least need to be reflamed before use. Whole roll for $50 plus shipping. Or 2.50/meter plus shipping for smaller orders. Vin@whiteroomcu...

19oz triax

I have a big roll of 19oz Vectorply triax glass . It is 8” wide. I don’t really know how much is on the roll and I don’t want to sell the whole thing. But I’d be willing to sell it by the meter for $5/meter. Buyers pay shipping. This material would be good for lighter/softer skis or for use in short...

Re: Drag knife Add on for Fusion 360!!!!

As an update, the drag knife add on has been reduced in price to $6.99.

I’ve been using it some and can say it’s worth the money if you are using a dragknife with F360.

Super easy to program and and great cut results.

Re: Pre-treating paulownia or balsa core

For this core I only have 2 19mm strips in the core. I’ll paint it on just these stringers and scrape down the excess, give them a light sanding and lay them up.

I’ll probably tape the stringers next to them to keep things from getting messy also.

Re: Pre-treating paulownia or balsa core

Great info!! I think this is what I will try. I’m guessing that it really doesn’t need much resin at all to partially seal the pores.

Thank you!

Re: Pre-treating paulownia or balsa core

I was thinking watered down wood glue would work well. I may try to test this on some scrap this week.

Re: Pre-treating paulownia or balsa core

MM, I’ll have to test that I guess.

I may just lay up as is just to see what happens. My buddy in big time snowboard biz says it isn’t really needed...

I’ll see I guess.

Re: Pre-treating paulownia or balsa core

I was thinking thinner resin so it soaks in but does not totally seal the top surface but just kind of creates a less porous surface so the thicker laminating resin does not get soaked up too much.... On Wagner’s web site they mention soaking their lightweight wood cores in resin. This is where I go...

Pre-treating paulownia or balsa core

I'm getting ready to build my first paulownia core skis. I've read and been told that Paulowinai soaks up a bunch of resin. I've also read that certain builders "pre-soak" their light weight cores in resin. I'm assuming to prevent excessive resin uptake during pressing. Does anyone have insight to t...

Re: Setback sidecut

I think more about what percentage of the ski is the waist placed. For freeride skis I usually use ~56% when measured from the tip. This seems to give my skis a good balance of turn initiation while maintaining float so you don't feel like you might go over the front of the ski. For a front side car...
