Yeah, good call MM. Now that I've got the silk screen process down I'm good to go. I'll keep the iron on for some logo T shirt swag.

Thanks des. I can't wait to get some urethane on these. I've been trying to get a way to print some more detailed labeling first. Tried rice paper, in a test the urethane ate the ink first, then the rice paper. Iron on would work but I want to add a label to the tail and can't iron on the curved par...

I was thinking about the clear topsheet. But Huck's board looks awesome. Thanks for the tip Richuk.

So a few catch up items. I replaced my last blown 25 amp SSR with a 40 amp SSR. I've pressed two pair of skis since and not only is the SSR going strong, but it seems the better SSR is allowing the PID to keep a more steady temp. I'm not sure if the 25 amp SSRs were too small (although only pulling ...

I've had some delams at the tips/tails using entropy, but pretty much chocked it up to: too much pressure at the tips/tails, and not enough heat at the ends. The heat issue was due to the skis being longer than my heat blanket. Easily remedied. The pressure issue was as a result of my "bladder ...

So I have some triax carbon fiber from Braider that I am wanting to make a good looking all carbon ski with. I was searching for how to get a clean, shiny look to the top layer and ran across this old thread. Interesting posts, so since someone else got it going I'll add my 2 cents. Twiz, there's po...

I have vinyl cutter envy. Great looking skis.

Falls, when you use the vinyl stickers/stencils can you re-use them? Or are they a one shot deal?

Re: delam? The first ones delamed because my blanket didn't make it to the ends. Stupid me on ordering a short heat blanket. Not the best style, but on this Saturday's cook I cooked it with the blanket running just past the tails of the skis, then decompressed, moved the blanket to the tips and rei...

Thanks for the tips MM. Yes, using entropy CPM. Which reminds me, I need to bring them back in the house for warm keeping... I'll try the next ski right to 180. The 3,000 watt blanket seems to get the job done pretty quickly. Hopefully that will give some camber. I cooked a pair this weekend, and ra...

Yes, I have got a fuse between the SSR and the blanket. Perhaps since I'm running 220V I should have both leads fused... seems like overkill, but it wouldn't hurt I guess. The fuse that's in there didn't pop. It's either a 15 or 20 amp ceramic fuse.

Thanks skidesmond. Yeah, I figured with the first pair that I would be happy if they either looked good or skided good. Though there are some obvious adjustments I need to make to the flex (too stiff of a tail and the stiffness tapers off too quickly at the tips) they ski pretty well too. I'm glad I...

So pressing two sets of skis I am 2 for 2 in burning out solid state relays. Here's my setup: Heat blanket: 220V, 3000watts Controller: TA4-SNR, control output 0-10V DC SSR: 25A, 380V, control 3-32V DC. Mounted on 40A heat sink. Contactor: 25A, 240V. I figure that the blanket is only pulling around ...
