Assembling the propeller shafts and flexicable

While I am waiting for my motors to arrive I went ahead and assembled the flexicable (Left + Right) to the propeller shafts. You need 4.75mm flexicable, one clockwise rotating and one counterclockwise rotating.

I sanded the flexicable by putting one end in the drill and turning at a medium speed while sanding about 1.5-2cm of the other end of the flexicable. IMPORTANT make sure to turn the drill in the correct rotational direction with regards to the flexicable so you don't unravel it.
If you did not realise by now the flexicable has a specific direction of rotation and since we have twin shafts and they are counter rotating we have a left and right. So depending on which one your are spinning in the drill you will need to change directions for the other one.

I also sanded the inside of the propeller shafts using some sandpaper rolled up on a stick so it just fits inside the shafts.

I glued the cable into the shafts using Loctite 648 which is a high strength, high temperature product specifically designed to assemble cylindrical pieces. The 648 specifically allows for a little more "space" between the two parts being assembled.



Before gluing do a pre-fit check to make sure the flexicable fits all the way into the shaft, if it does not you might need to sand a little more then clean both the inside of the shafts and the flexicable extremely well, I used acetone and a toothbrush.

Allow 72 hours for this to dry and you should not have any problems with the shaft parting from the flexicable.
