The Shape Shack / Fin and Foil design with finFoil.io

« on: December 22, 2020, 05:10:52 AM »

I got an email from Hans at finFoil.io and had a look at some of the newer developments:

1. Fins can now be designed with fin bases
2. There are different rendering materials
3. The window has buttons  for standard views as well as a dynamic 3D view
4. There are accommodations for wing and foil design (mirrored pairs, importing *.dat files for loading in known foils, and the ability to design anhedral and dihedral curves like gull wings)

I am not a compensated spokesperson, just a fan from the beginning and have made many fins using the software. It has always been easier that 'regular' CAD systems for achieving nice foils. Design and lower resolution outputs are free, higher level stuff can be bought on as as-needed basis. Hans has also helped me solve other CAD issues related to fin design and manufacturing. He can also make fins to your specifications.

The Shape Shack / Re: Wanted a handle on the bottom of my foilboard - got a gore breather handle

« on: December 20, 2020, 02:36:48 PM »

Probably OK, kinda like duck-diving or falling off and flipping (more my style) a board with it on the top.

The Gore membrane should only allow vapor through and not drops.

I would ask the shaper and/or confirm that it was installed to actually breath (hole drilled under vent plug through the main handle if it is the removable kind).

Are people willing to share their recommendations for 'cutters' who are better at different CAD formats and/or non-standard surfboard shapes?

The picture of the cut also shows what good side lighting can reveal in a shape or blank.

All the best for the build!

On my Win10 computer, Shape3D files show up as a wave inside a circle icon, regardless of what folder they are in. Regular *.BRD files are attributed to BoardCAD with a different icon.

I did your numbers on a new board 19.625" @ 12" from tail  and 21.5625" @ 12" from nose and got a pointy board too at 6 foot something. I resized it to 8' and 24" wide and still pointy. I grabbed the control point for the nose in plan view and pulled it up and it started to get that longboard look.

We ordered some WR-LPU from System Three for the clear coat for the board in this thread.

I also have an electric drafting table that was earmarked for a shaping/glassing stand but I found the big flat top so useful for projects that I have not sacrificed it yet. 

I also have yet to try crutches for stands, I have plenty of those to mess with too...

I like the floatie. 
Those coiled leashes look nice too.

I ordered some System Three WR-LPU directly from System Three. They were the only company that answered their tech support form multiple times with thoughtful answers.

The other choice would have been a 2 part rattlecan LPU reccommended by another shaper/surfer (paint is called Max2K) but after 8-10 spray cans my daughter is having wrist issues and the WR-LPU can be sprayed with a cup gun or rollered then tipped with a brush. I order a big can so I'll have some for myself for other projects.

Season's almost done here, we need to get 'Sugar Booger' coated and in the water for a paddle before the weather turns.

Thanks guys. If this thing wasn't still shedding glitter after the first coat of clear I would consider the sealer/wax methods.  I think I need something with a little more body to start.

What are people using as a clear coat to their 'artsy' painted boards?
The one on my 'R/R Shaping Stands' needs a gritty glittery acrylic art paint buried
So far I am leaning towards a linear polyurethane (LPU).
Is that the way to go? Other ideas? Thinking a standard auto clear might be too 'hot' solvent-wise.
Thanks, J

We love us some homemade boards too!

The board has moved from glassing to paint.

My daughter chose a bright yellow/green base followed by a green and gold glitter and a little clear.
She also ordered in an entry level carbon paddle, grey traction, and a nice leash. Maybe a fin too, just glad she's working the paint and finishing details so I do not have to.

Its working name is 'Sugar Booger'. At this point the board has a textured and iridescent finish that is hard to photograph, seems to wash out in the phone camera.

We need to figure a clear coat that will fill in and seal it for water use but free of hot solvents that would affect the acrylics and glitter. Would this be a job for a 2 part polyurethane? We could roll and tip or use a low end cup gun. It's been rattle cans so far but I am afraid we'd need a half dozen more clear just to make a difference. Not going for show car stuff, just done and serviceable.

Tech support chat with big online paint distributor yielded nothing, afraid to recommend anything for 'marine' use. We also have a message into the rattle can company.

General Discussion / Re: Board Bags ??

« on: August 09, 2020, 08:41:17 AM »

Someone on Sway's did a test of board bag materials and white cloth/paint was better at reflecting than silver cloth, which acted more like a medium grey instead of a mirror or space blanket.

Probably best to keep all first order magnitude sun, rain, wind, snow off of the bag and the board inside.

The Shape Shack / Re: Question(s) On Foam & Floation

« on: July 19, 2020, 02:36:50 PM »

The true weight of the foam might be less than 1 PCF.
If the shape is accurate for liters and the scale was accurate for the machined blank, you should be able to calculate actual density of foam.
94.65 L corrected for .88 PCF= 107.65 L
94.65 L corrected for .82 PCF=116 L
Or so it would seem if I did the math right...

The Shape Shack / Re: How to fix delamination bubble?

« on: July 17, 2020, 05:34:37 AM »

I have an old windsurfer that I went after a couple bad spots and before I was done I was dug into the HD foam and EPS layers. I got a little bummed and it's been 'drying' for 2-3 years...

If you are not familiar, the Board Lady website (Eva-M. Hollmann) below is an awesome overview of all things related to board repair. Many pages of info, here is one to start.

There are also videos online from NelsonFactory that show new construction, they kinda help me get into a 'headspace' for multilayer composites.

The Shape Shack / Re: Custom Torx Tool for in water foil adjustments

« on: July 11, 2020, 07:54:06 AM »

Ok Jrandy, 2 things. First that knob is nice. That’s what Josh does a lot of as well as really cool chopsticks.

Second, um, rat rod RV? Why am I just now hearing of this?

LOL because it is more 'rat' than 'rod'...

Previous owners used it a a festival camper and neglected the butyl around the windows, etc so there is lots of rotted framing. It is the paneling/styrfofoam/2x2/plywood/metal skin type construction. I am stuck between wanting to fix it and wanting to get rid of it The motor runs really nice, all appliances work except water heater, currently redoing the carb on the generator.  Flor is weak, carpet is old, brakes are out, front window is redone but not installed, does not have modern rims... I am trying to suss together the brakes at link below along with a promo pic, think early 70's Winne Chieftain and you'd be really close:
http://www.classicwinnebagos.com/forum/index.php?topic=15416.0

If I were to do this again I'd go for something with more metal or fiberglass in the superstructure.

Again, great job on the resin handle for the Torx.  Upcycling at its finest...
