New Tuttle system with lengthwise stainless pin, insertable from back of the board will be the mast plate killer.
Same pin will also ensure strength and stiffness of the board.

I really don’t understand why not using TT inserts?

My wood plank will have heaps for straps and a plate...

http://boardbuilders-forum.1077691.n5.n ... -td30.html

Plus, once u discard the board, inserts are reusable...
They are generally m5. Have shorter threads. Might work, but dont think it's robust enough.
What is M5? SS inserts? No, not a single TT I know of is m5, but M6.

It is not the threads but the insert plate making robust connection.

Each to his own I guess.

The new Abracadabra is pretty much a killer plate ;)

if a board is too thin to use Chinook strong boxes, I use these things.
Rocksolid , you will break everything before you break this.
all stainless steel

tried out my Balsa board yesterday. 110x47cm , 2,6 kg
Results:
Outline is good- super forgiving during starting and touch downs at speed and slow and crashes. Next board: make it 1-2 cm narrower overall and reduce nose width
Flat deck is good- takes some getting used to- will need a few sessions to adjust.
Textured deck is excellent: grips great, easier to move feet and do foot work. Big improvment and saves 220g and money.
My homemade kickpad sucks ( not in photo) - looks terrible and didnt get it to stick down all the way. its good to help with positioning board during waterstart. Will use a small bit of deck pad instead.

Ride: swing weight at nose is greater than the orange/magenta board, despite the fact that the O/M board wieghs 2,7kg. This effects boards feeling in air, the balsa board is slightly less agile. Next board i will make with one less layer balsa and make it hollow in nose area to reduce swing weight.
The tail block is really ugly and added weight/time to build- plus a potential weak spot. next time i will scarf the planks to 110cm instead.

Still have to ride this one hard to test durability, and get other rider inputs. But pretty close to a good design, materials and method.

Grip is built into the top epoxy layer. Thats the cost effective way. There are also some stick on and spray on versions. Very thin and usually transparent. Saves the weight of a big sheet of stick on EVA foam but there are persona preferences for foot comfort. If your wearing booties, texture is great. If your barefoot, some like to have that bit of cushion under their heels.
