Backing Plates

[Mr. Sandman]

Panties aside...I found one of those multi-master tools with a sharp chisel bid cuts old 5200 off OK. 4200 is even softer (yet plenty strong) my rule of thumb is if it sees water pressure below the waterline then use 5200, if it is above the waterline and someday you may have to remove it then use 4200. Both create are very strong bond and should last the life of the boat.
good stuff.

I found you can order lots of sizes and shapes of G10 from Mcmaster carr but basic sizes are available off amazon.

That G10 stuff is some hard and stiff stuff! I was able to cut it with my chop and table saw (albeit slowly) but after drilling a few holes on the drill press the shavings caught fire as they were sucked up by the vac. (It has a nasty smell when you machine that stuff) I had to check the vac to make sure I didn't start a fire in the vac.

It will make a great backing plate though. You can really crank on it with a bolt and it will not rust/warp/corrode or interact with anything. Uuber strong stuff.

I gotta get some more .. Thanks for the tip.
