Shaft Install.

Next problem is to align and install the prop shafts into the hull, they are 235mm apart and are separated by the tunnel.

To keep them perfectly aligned I made some 3D printed jigs to hold them in place while glassing them in.

This one lines up the motor with the prop shaft.

To space them correctly and to be able to adjust the height, they are joined together with this part,

Next is this jig that holds the shafts on the outside of the hull,

The tubes were roughened up with the Dremel and to seal the outside of the hull to stop any resin seeping through I used something that would never leak – Joysway’s Hatch Tape!

It was then just a simple task to glass the prop tubes to the hull,
