for the guys who do full length woodcores and use bent aluminum molds...how do you hold down your cores during lay-up? or do you prebend the cores as well?

Used to prebend my tips with a hot water and a jig (davide explained this with pics somewhere)
Prebent tips don't try and escape from the ski/board for the rest of their life - seen a few Elan's delam in the tip from not prebending!

This is the ugliest thing I have ever constructed.
I made it entirely out of garbage basically and leftovers even the epoxy.
There wasn't enough in the hardener to make the pump function so I eyeballed it.
Hey man, when it comes down to real engineering, whatever gets the job done the fastest and the cheapest is the best solution. It might be ugly, but it's still elegant
with the 3/4 edge wrap problem you were decribing (ignores the last bit), could you use a sheet of thin aluminium on the base side to try and create a "bridge" for the edges to the tip, sort of get the aluminium to act as if the edges are continuing all the way to the tip. Not a great explanation, but if the aluminium supports the edge set it may allow the ends of the 3/4 to get bent well too?
Very cool! You already figured out the replacement for the Irwin clamps, right? 2 threaded eye bolts with wingnuts/knurled knobs and a slotted squaretube is what I'd do...
Yup that's how it works.
Mine is attached to the end of my work bench.
I've been clamping a 1x4 maple board to hold it down.
I let the first one pop back up (rolled past the tip) like in the revolver vid but there's a lot of energy there and I was worried about the edges popping off.
Still looking for a bigger main pipe.
Also been thinking about 2 smaller rollers that pivot instead of just one.
Thinking it would bend more like a slip roll.
I'm still having the edges go slightly out of plain.
I'll work it out when I find the time ( ha ha ha)

You don't even have a legit signature, nothing to reveal who you are and what you do...
I was at the home center at lunch today looking for 5inch pipe in the plumbing area. I need to think a bit more on how to make it, that pipe is expensive. Maybe I can get a piece from my brother-in-law who does plumbing and hvac.
And really, you could cut some circles from a 2x6 and glue/screw them together and sand it relatively smooth. This doesn't need to be anywhere near precise, it's just a rough bend anyways.
