Alright Guys,
I found some 2x2x 1/8" wall chrome moly square tubing. If I use it for the spacers in the cheek plates of an RAF, what kind of damaging electrolic effect are we talking about? One guy thinks it's really a serious matter of catastrphic failure, another tells me that yea, in a hundred years or so. My own experience with another ship showed no ill affects, maybe because I painted the steel? I understand that powder coating won't work as an insulator, I planned on painting them once sized and fitted white so that if any cracks occur, dirt and dust makes them show up easily. I know this to be true from when I was a helicopter operator/owner/pilot. I plan on using the chrome moly spacers in an attempt to stop them from cracking. The factory wants them replaced every 50 hours, pre and post flight inspections. I'm pretty thorough but if the factory mandates it then there's a fix for it. If anyone has any ideas to insulate the steel from the aluminum, maybe a thin layer of plastic, maybe painting plus some plastic. I'm open to ideas. Using chromo moly will result is a stronger mast less prone to the spacers cracking when aluminum is used. I know another RAF owner who has 3-400 hours on his, but also confirmed the cracking problem. Merry Christmas, John
