Isospeed 7500 1.4mm (NOT 1.2) rolls. 8/4 Deadline!

So we are trying to order Isospeed 7500 direct from Isosport in 1.4mm thickness. The 1.2mm stuff that is readily available doesn't match standard metal edge, so you end up with less to grind and edged base that doesn't sit as flat in the mold. Isospeed 7500 is high quality base - higher molecular we...

New online material store (w/ bulk edges)

So recently our source of 10 lbs edge rolls dried up. We decided to invest in larger batches of some items and offer an online store. There seemed to be a need for an east coast one. Some highlights: -All items listed as per foot and continuous for reduced waste -Bulk edges (and per foot) -Local pic...

Thanks guys for all the input. It sounds like I will be trying either a card scraper or a mini spoke shave. Funny thing is, if it were 80yrs ago, we would have a slew of great woodworking hand tools to choose from...AND nylon wouldn't be invented until next year!

I should clarify, I am not talking about sidewall beveling. I am talking about strictly topsheet beveling. While sidewalls are often beveled between 3 and 30 degrees (from vertical), production skis often have an additional topsheet bevel of between 45 and 60 degrees (from vertical). Because this be...

Topsheet beveling

What methods are people using to bevel their topsheets (if you choose to do so). I have been putting a 45 degree bevel on our topsheets using a combination of filing/scraping. I thought I was going to be able to do this with a small router, but the top of the ski has too many changing contours for a...

Wow, been busy and forgot to keep an eye on the thread. Knightsofnii, I was assuming it was for delam issues and the "smoothing out the ride" was just a line. Doesnt NS just use VDS though (for sidewall delam resistance), not this thick urethane layer? I just wonder how it is bonded in order to be a...

They seem like they would be a Never Summer ski - but no, it says Made in China. I was saying that thin VDS is probably cheaper than the thick urethane. Thick VDS is pricey.

MM, I agree - its definitely urethane. But do you think they just epoxy a strip of cured urethane onto the sidewall during the layup? The fact that it ends perfectly in line with the sidewall makes me think that that it is somehow pre-applied to the sidewall strips. If it were during wet layup, woul...

Liberty sidewall puzzler

Ok, so one of our customers ended up breaking a Liberty Genome and donated it to research. What really caught my eye when I cut it open is an elastomer layer that runs the full perimeter of the ski along the top of the sidewall. It is easy to push a fingernail into (60 to 70A durometer I would guess...

The press looks great! How are you fixing the location of the adjustable tip/tail mold blocks?

What is the point of a cattrack if the bladder is below the mold? It seems like they are just using MDF matched molds (like pressing skateboards).

6" for a 150mm ski give you 2mm of leeway...seems risky to me. Its all personal preference, but we like a bit of extra to play it safe. It all depends on your process and how confident you are wetting out glass with minimal fraying (the more you stay away from the edge, the less likely it is to fray...
