- Hi where did you source your stainless rails?
I just went on Ebay
http://stores.ebay.co.uk/ridethewavesboatchandlery
and bought the marine grade stainless steel lengths and the supports, T and elbow joints, I went for 7/8th inch diameter to keep the weight a tad lower than 1inch diameter, no welding involved just a lot of careful thinking about it, the front two uprights pass through the gunwales and are braced sideways as well as through the "feet" which are held by stainless bolts with plastic bar reinforcement on the underside to reduce strain on the fibre glass. the joints are held by grub screws with thread lock for added security against the motion it will be under.
Inside the tube I sprayed oil, pushed strips of EVA foam in and sealed with silicon.
Loose fitting before tightening and measure sixteen times before cutting ( which I did with an angle grinder ) avoids mistakes.
I'm a happy bodger when it comes to getting on the tools but I'm getting there and thinking through the engineering side of things is different and a nice relaxation to how I earn my living.
Meccano for big boys really!
