I would say it's a template to cut the curve in the veneer...

Yes, the curved MDF with the holes is indeed a template to cut curves in the veneer. It's a 21m arc or so, with holes to make it a bit lighter and easier to handle. A sharp eye will note the holes are not along the centerline of the form... a mistake I corrected in subsequent templates.

Quoted from an email from Trevor at Vectorply

"For hand lamination, the ideal fiber content (fiber weight fraction) is in the 50% to 60% range (50% to 40% resin), ... [snip]"

Vinman, that’s really interesting, thanks! I have a similar range in my head from a composites book that I read long ago, but I’ve misplaced it. It’s gotta be in this house somewhere and when I find it I’ll add a reference.

My buddy in a big time snowboard op r&d says 38-40% is what they try for.

To clarify, is your buddy saying they aim for 38-40% fiber or resin? I’m assuming resin but want to confirm since that seems quite low for fiber.

And Rich, thanks for the link, I’ll give it a read!

Yes 38-40% resin

The figures quoted by Vector ply are a reflection of the process employed, with one process being more efficient than another.

So the question remains what resin/fibre ratio provides for the best mechanical properties relative to the purpose and process being employed - that get's you to the factory recommendation. There's a Never Summer video on the site that shows their approach to this issue.

Video:

Plastic tips/mini nozzles are available for Super Glue. They will define the size of the droplet, according to the viscosity of the glue being used and you'll have no more issues with too much glue. They also help will accuracy - especially in the cold. Super Glue, is moisture cure and if you are in a moisture rich climate, you can bond quickly by applying the heat (allow the soldering iron to slowly warm the tine), it speeds up the reaction. Only useful to know when you are mid layup.
