Numpty, On your first question, it’s been a long, long time since that picture was taken. I don’t actually know whether I was done with wetting the top glass, or had simply stepped back briefly to let the picture be taken in the middle of wetting it. You’d like to see your glass go translucent when ...

Heat is always better, even for epoxies designed for a room temp cure. When I vacuum bagged I actually built a “hot box”. You can see it in the pics here: http://www.happymonkeysnowboards.com/mike/OldVacuumBagging/ I made this out of 2x4’s, drywall, and foam insulation in between, essentially just l...

Twizzstyle’s right on here: it’s the much lower pressure you get with vacuum bagging yielding poor squeeze out that’s your biggest problem, so you need to be much, much more careful about where you put your epoxy. A capped top sheet doesn’t help matters, either, since you are correct that there is p...

I used to use a 45 degree bevel when I made cap snowboards with vacuum bagging. Is it “enough”? Kinda depends… the edges of those boards held up very well to everything but rails. A good hard hit on a rail, though, and it would delam. Only delams I’ve ever had. With a sidewall board I’ve never had t...

Here you go: http://mathworld.wolfram.com/CircularSegment.html I think that with a tiny bit of discussion you’ll find that you can get a reasonable group of people to agree what these two terms should mean. Unfortunately, that doesn’t mean anyone else in the industry agrees with you. You will contin...

I’ve done it… once. I cut an entire mold, including nose/tail blocks out of one big glued up block of MDF. I still build my molds by cutting 21 pieces and bolting them together :) It’s faster, and has acceptable accuracy. It’s a time/accuracy tradeoff, or a money/accuracy tradeoff if you’re contract...

Re: polyurathane glue as core glue up
Yes, it will, but it is _not_ structural.skidesmond wrote: One thing I like about is if you dampen the wood very lightly and then do the glue it, the glue expands to fill any voids.

Your core glue doesn't need to be waterproof. It's only purpose is to hold the core together until you get the board laminated. Your glue choice should be dominated, then, by other useful properties, like open working time. Polyuerthane glue has a nice long open time, and is perfect for this. I use ...

I have a Fontaine base grinder, model 1404. Fontaine is (was?) a US manufacturer that, for a while, made machines over here for Wintersteiger. My machine was actually sold by Wintersteiger as model SNB 55. The manual that I have suggests the following address for the manufacturer: 200 27th St. Sacra...

Yea, turnout was weak, both from sb.com and ss.com. Kelvin and I were the only ones from here... we had a good time chatting about building and whatnot. He brought up a whole bunch of extra material he was willing to pass out, and I brought up a groovy prototype core for show-and-tell. Too bad we mi...
