As we consider replacing the turtle hatch
(see that thread here
) it occurs to me that since we have access to amazing aluminum
fabrication shops that making the new turtle hatch
out of aluminum
could be cheaper and lighter than steel
, aluminum might be an option. The issue is one of insulating the steel
and aluminum from one another.
To isolate the steel and aluminum it occurs to me that a single
, shaped piece of 1/8 HDPE could be used between the turtle hatch edge and the deck
, the bolt threads could be coated with lanocoat and we could use HDPE, or nylon washers or even neoprene compression
washers to insulate the bolt heads.
I am keenly aware of the danger
of mixing metals. An am curious for some feed back on this project
I welcome all ideas and input, thanks.
