Re: Direct mast mount to board? (wooden board build)

Chesapeake, ...bigheads should be in high density foam, at least 80kg/m3. I have used HD plate over entire mast plate area and just 4 local blocks and both hold up on strapless boards. Hi Tom, would you use HD foam in a wood build? I had been planning to use solid paulownia or balsa blocking around...

threaded "potting" inserts for straps and mast mount

Anyone tried something like this? One advantage I see over the typical T-nut is they are closed at the bottom so one less point for water infiltration. They're designed to be set in resin. I haven't found a good US source yet but haven't spent much time looking yet.

Re: Direct mast mount to board? (wooden board build)

Thanks all! I wasn't aware of the tuttle adapter option. Although, that doesn't get rid of the bulky base in the water so maybe I'll go back to an earlier idea of mounting the LF base normally but running the two mast bolts through to the top deck (see pic). Countersunk so they are flush with deck. ...

Direct mast mount to board? (wooden board build)

Anyone have experience building a mast slot into the board (i.e. no bolt-on mast base)? I was thinking about sandwiching to carbon fiber plates, one inlayed into the deck with the 2 bolt holes and one on the bottom with the cutout for the mast. I would then fill the middle with high strength casting...

Re: Seeking design and build feedback: pocket foil build (paulownia)

Mate, With all due respect, do yourself a favour and use a KISS approach. It might sound shocking but I would never ever attempt to do something like this. Why? B/c Paulovnia 12mm core it a tank when glassed both sides with light FG. Weight? Umm, maybe 3kg or Less? Rocker can be made in a few ways ...

Re: Seeking design and build feedback: pocket foil build (paulownia)

I'm not into board building, just wanted to chime in with few photos of a paulownia hollow core foil board made by a friend. Chris builds mainly paulownia 'alaia' kite boards and is very open to sharing knowledge and experience with colleagues and DIYers. https://mega.nz/#F!3CJEUKYK!RRsaLw1G1m0uuR0...

Re: Seeking design and build feedback: pocket foil build (paulownia)

just an idea, so as not to weaken the front of the board too much by hollowing it out, depending on the grain of the wood. with 1 inch wide slats, make a type of H beam with each slat. where you want to lose weight but keep more rigidity. It is easier to put reinforcements in foam. I'm not sure if ...

Re: Seeking design and build feedback: pocket foil build (paulownia)

- I’d make it at least 11” narrow where you place feet and not much wider elsewhere - I wouldn’t bother with emptying the core, just narrow it from 17” to 13” Thanks! I based the width on typical length/width ratios I have seen in production boards. I'll have to pay more attention to how much real ...
