The video below shows the lathe that I built to facilitate making some of the elements of the boat lift. It will be used to machine the pistons, chamfer the end of the cylinder which is necessary the install the piston/seal assembly, and turn the ends of the connecter pieces for the lifting cradle.
My home built lathe to perform several different functions in the process.
Process to smooth the bore of the cylinder using my custom hone made from a cylinder of wood with 3M wet/dry sanding sponges and a hose supplying water. It worked quite well I must say. Note to self... keep you shirt on when make shared videos.
This is the lift of the full sized Bocas Marina launcha. Unfortunately we didn't get it centered particularly well which require a lot of fiddling with the control valves to lift it.
Version 3 of the locks that hold the lift in the raised position.
