Thanks Matt! There are some slotted brackets in the works... I actually just pressure tested the whole thing yesterday without the cat track or the mold brackets and brought the bladder up to 45 psig. Totally pumped. Got maybe .5-1mm of deflection which is pretty much what i calc'd out. The bladder ...

Cool idea Goz! I like it. Not for me on this revision. MM, dammit, that is a good idea. A tubeless tire kit for mountain biking should totally fix that. I'm into it MR, that seems like the leak path was up the fittings and into the firehose matrix. I used head monkey's sealing system and kept it cle...

Jsquared Year II
Welp, last year my buddy and I got hooked on this. We started of doing the boardcrafter design style press, had a good time, made a few crappy boards, and learned a ton. Since then, we've both gotten more into woodworking, acquired a pile of tools, and been busy thinking and designing. This year, we...

I haven't used thermal blankets for pressing yet, but I work lab scale and industrial ovens heating elements. I do not think an averaging function for multiple inputs is necessary in the PID controller. The reason for this is that when you finally get the blanket to the temperature to what you want,...

OK, well after building and riding a few boards, this snowboard building thing has slowly started taking over my life. Guess it's time to kick it up a notch. We're going firehose press. Got some box beams at sub scrap rates from work. Did a bunch of calcs, sims, etc. Should do the trick, and I've se...

Really think the reason for vert lam is to retain the stkffness and longevity of rebound over time not intially. Couldn't agree more. Bending stress distributes through the dense grains... if you have a layer of dense on top of a layer of less dense, you will cause a local stress riser and start to...

Whoa really? Surprised about the deflection. Was your press out of 6x3x0.25 steel? The moi is pretty big and rough calc for max deflection at 50 psi is .009in. 'course, I'm taking notes and trust your guys experience more than my spreadsheet. Just saying...really surprised about the deflection comme...
