CANPA hatches hinge problems
My Nic 'HOPE' No. 117 has had problems with the stainless steel hinge pins corroding in the alluminium alloy frames - a perennial problem in our salt water environment. Eventually the SS failed involving an expensive job to extract the stump and replace.
This year's solution is to replace the original quarter inch (6.3 mm) pins with a pin made from 6.0 mm rod leaving more room for grease or barrier paint. I have also had the end of the new pins drilled and tapped for 4mm bolts to make extraction easier.
