Re: Immigrant board Mk2

Another option for removable/changeable wings could be morphed off the Greenough bolt on fin idea in attached .jpg's. Maybe flat metal strap bolted into wing, wrap around board and bold through. Only hard part really would be matching shape of wing edge to board rail for tight fit. Not sure of could...

My mind gets drawn to complex, compound curves, magic edges, vee hidden inside double concave, etc. But in 50 years of riding waves, 100% of my best, most functional, most fun boards have all been simple simple simple

Re: New summer Groveler

I detect a noticeable difference in 5# vs 10# paipo boards. I too notice significant differences between light and heavier boards. On paipo, swing weight isn't much of thing the way it is on stand-up esp longboards, but remember, much of the time when riding you are at least partly unweighted which...

Re: The Immigrint board

It was years ago so likely better design/materials now, but I had a no zip pull over (3mil, 5 mil) and though it was super warm and comfortable in the water, it was truly a bee-atch to get off over my head. I can remember two times when tired after a long go out that I just couldn't. Once in near pa...

Rod your theoretical 50" X 10" board would make a good weapon for hunting/spearing small game. Just make sure the nose has a nice, sharp point

Re: TBG5

Can't remember who said/where I read, but quite a few years back I remember reading that GG style hulls, at very high speeds, will plain up on smaller and smaller area along the midline and lift out of the water. Not likely in continental US type waves, think Sunset, HI beach West swell type power. ...

Re: Spring session

Zensuni, I don't know if this would work so you'd want to test it on a sample piece of neoprene--there is a product called Vulkem116, some sort of silicon caulk, that dries rubbery and bonds very strongly to what you put it on when its fresh from the tube. Some people, used to be many, used it on th...

Re: 45 biaxial degree fiberglass?

I've never worked w/ cork but have read (and makes sense to me) that you can seal it pretty well without loosing is "soft", forgiving qualities. Squeeze on thinned epoxy so it dives into the crevices and leaves little to none on the surface. Probably would also work w/ varnish.

Re: 45 biaxial degree fiberglass?

That is the grace of this idea, there is no fiberglass in these parts. in fact you can laminate the fiber cork fiber cork eps in rectangular fiber and then cut with the template of the paipo, sand the edges at 90 degrees and paste the cork to make the rails. a Bodypo style but lighter thanks the co...

Re: 45 biaxial degree fiberglass?

Only issue could be that 2 light layers is stronger than one heavier one. Oh, and thicker/heavier cloth is more difficult to wrap on thin rails and corners etc.

Re: hanplane templates ? measures?

Just my opinion but I don't think handplanes need a fin....your body acts as the "surfboard" and the handplane is the fin. The can be any size. It is really just a matter of personal preference. 18 inches is plenty long enough and width is also important to how it handles

Re: Front fin(s) ?

I think maybe better performance if you can figure out prone weight shift to engage the rail more. Not sure if easier or harder to do prone vs standing but here's a really nice standing version, I may have posted previously somewhere here

Re: Do swim fins generate drag significantly ?

Quick note on Viper fins fit. When I lived in Sonoma County in NorCal it was cold water all the time. I just bought up a size from that suggested by my shoe size and wore 5 mil booties in them. Perfect comfort and all the rest of the Viper benefits.

Gorilla Glue is sturdy stuff but you MUST clamp very well because it expands a lot as it reacts. And it goes off fast so be ready for that.

Re: longboard fin box in paulownia 18mm?

Unfortunately, board is long gone and I did not save photos of how I built the fin. But Dale Solomonson explained to me over the phone how to do this. Not sure if this will work with wood board but it was great on fiberglass flexspoon. You will need to build your own fin or at least add thick faring...
