Fittings such as skin fittings should be positioned against the hull and circle marked using a perment felt tip marker around the fitting.Then using a .25" masonry bit and a high speed hammer drill bore aseries of holes close to each other all round the circle,sothat the finished hole is at least .25"larger than the fitting when finished.Get an accomplice to hold a mash or sledge hammer againist the inside,while break up the centre of the hole with a hammer,wire cutters and a hacksaw to cut any mesh or steel rods.The fitting is then given a liberal coating of grease on the thread,flange and nut.Apply a large amount of epoxy filler to the area around the hole in the hull as well as inside and outside including covering any area that may have been chipped when cutting the hole.While the filler is sill soft,carefully push the fitting through the hole keeping it centred and finger tighten the nut on the inside.When the epoxy has set undo the nut inside then unscrew the skin fitting from the hole the grease will stop it from sticking.Then using a sander,smooth both out and inside surfaces back level.Fitting is then refitted with non harding mastic i only use stainless 316 fittings.
