Rodndtube
My mind is trying to avoid the tubes system, because I would always be thinking if I get slammed I’m going to get stabbed. Might not be real, its just that I would fear that. I’m sure guys with tube joins know that fear is nonsense. But in reality people like me wouldn’t even want to challenge the fear and so wont want to purchase. Stupid I know, but I want to consider other directions
I have been thrown about 2 metres onto rocks with a bellyboard fins up, did a twist and managed to break the fins and crush the tail area of the board.
idea1
An idea going through my head at the moment is a sort of biscuit join system. You know those things you buy at the hardware shop, for joining sheets together so they stay flush. Well to NOT to use them but a similar system.
So imagine 3 sheets of any material on top of each other. imagine all three fixed in position. Now imagine if the sheet in the middle had a shape cut out and it fitted perfectly into the shape it was cut out of. So lets say an oval that fits perfectly into an oval. That oval can’t move, it also can’t hurt you like a tube could.
So the question is of materials and thicknesses. Do they exist? Would you have to make a mould … very expensive!
A simple CNC machine program will cut out shapes to fit perfectly … thats easy.
I’d make that biscuit about 3/4 inch shorter than the cases length. If the biscuit and its case can be made strong and light and easily fitted solidly into a board, then it could work. Its possibly a difficult path to pursue.
idea2
An angled slice, could be straight or a radius, starts on deck forward, goes to bottom rear, could easily have locating methods, locking methods. Easily designed on CAD, easily cut for final fitting on CNC or purpose CNC made jigs.
idea3
Overlapping lip, I’ll try and explain in words, not easy, looking down at the deck, there is a male half oval (the top part of the rear half of the board) on top of a female cut out half oval that is the front of the board at the middle join, (sounds pornographic) and the same would continue on the botttom. This would give a lot of join strength and no sharp bits to fear.
idea4
A variation or combination of some of the above concepts.
Does any of that make sense … a lot of words no pics … want pics?
They are only ideas, seeds washed up on a beach. Tommorrow I will have other ideas.
Dont stress, ideas start of complex, end up simple.
