G-man, I’d like to suggest that you use larger motors. I used steppers with 680 oz-in of holding force for my X and Y axes, and 228 oz-in for the Z axis. A stepper motor has its greatest holding force when motionless, and I can overcome the holding force on either axis without too much effort by pus...

Turns out I already have a Whistler trip planned for late February: 2/24/08 thru 3/1/08. If it happens that you organize this during that time frame, then cool. If not, I’ll catch you guys next year.

Misc top sheet material for sale

Misc top sheet material for sale I have a few miscellaneous rolls of ISOSPORT top sheet material for sale. I got these quite some time ago and they’ve sat around for a while unused. These would be great for a home builder who wants to experiment with different top sheet materials, or for someone who...

I really like these: http://www.omega.com/pptst/5LSC_5SRTC.html I used the 36awg size. I’m heating with two blankets, controlled by one controller. But I have two sensors and two temp displays. I place one directly above the bottom blanket in the middle of the board, and the other directly below the...

FYI, I believe most triax fiberglass does not have an equal distribution of fibers in all 3 directions. It’s typically 50% in 0, and 25% in each of 45/-45. I know this is the case for Vectorply E-TLX 2200 which is what I suspect everyone is using. (If you get your glass from snowboardmaterials.com, ...

Yes, the graphics are sublimated. I don’t do it myself. I use a company called Creative Edge Graphics that’s here in WA. I don’t think they have a web site… I can dig up some contact info if anyone is interested. I rely on my cat track to insulate the bladders from the top heater. It seems to be wor...

Thanks for the compliments. I enjoyed building the press. Here are the benefits I see of the pneumatic press over vacuum bagging: 1. The top sheet is significantly smoother. Use a glare to see just how smooth (or not) your top sheet is to really get a handle on this. With vacuum molding the top was ...

Your average snowboard has a waist width of ~25cm. Nose/tail widths of ~30cm are common. For "wide" boards people will go as wide as the raw material will allow, which gets you a nose/tail width of 32cm (12.6" or so). You want the molds and press to be wider than that, of course: 15"-18".

Good luck!

Getting serious about a pneumatic press

I’m going to build a pneumatic press this summer to replace my current vacuum molding setup. I’m going with a design very similar to the one the guys at GrafSnowboards.com built (see http://www.grafsnowboards.com/ for pictures.) It will be wide enough to press a single snowboard or a pair of skis. I...
