Here's a simple way to think about it - Your heat blanket will put out a given power output - I think someone on here said about 3W/in^2 . Electrical power is a function of both voltage and current (p=iv). The reason many people run heat blankets (... and larger machinery, until a three phase motor ...

holey tip

Hey there, I'm also a racer - I finished up my last season of NCAA D-I eligibility this past spring and have, at least for now, put gate bashing aside. That said, I've skiied Fisher for 7 years. When the guys on the world cup started using the new skis sometime last January, I talked to my rep and o...

dye sublimated topsheets

I know that there are places that will print your design on topsheet material and send it to you. I appreciate the convienience of this, but it sort of goes agains the anti-practical, anti-economical nature of ski building. My dad has an old dye sub printer that I may be able to tear apart.

Sidecut geometry/ "ideal carving" and how it dicta

I've been turning many of these questions over recently and come up with nothing. I recently bought the Lind and Sanders book and jumped to the section about equipment. It does get into some detail, but it's not targeted at people designing skis, it's targeted at people who want to "sort of und...

Stiffness/ramp angle

Craig r, The reps weren't screwing with you when they were talking about ramp angle. I come from a racing background and not only does ramp angle make a huge difference, but companies are beginning to design for it.

Epoxy vs. Wood Glue

Titebond III is great stuff - but like nearly all wood glues, it's water based. This isn't a huge problem, but it does affect the water content of the wood you're gluing up - as I'm sure you've seen from wood lying around, moisture warps wood. It's probably a mute point - the amount of glue you're p...
