Yesss! This is exactly the solution I was going for also. And I was thinking about how to adjust this to the steeringhandle.
No you are coming with the answer! Super!
Btw, what kind of bolt did you use into the steeringhandle (black one)? I know it should be a 1/4" but I can't find such a "bolts here. And it looks like you did not use that either. Did you use a normal M6?
I´m just looking for a US 1/4 screw made in steel inox and with a flat head in order to simplify everything. In this way we will need only a good base made for example in hard plastic resin 4 or 5 mm thick(or duralumin), fit the flat screw in it and then fit the black pastic from the optimist stick with two small screws or rivets.that´s all...
I don´t know if explanation for the handle join is clear enough...
