Help wih recoring tank hatch

[abl1111]

I used polyester resin and 1.5 oz matt, with 3/4" plywood. I like thicker but that's just me.

Be sure to put hatch on solid, supported, flat surface before you start to dig out the old wood and when you glass 'er up ( or, you will have a twisted hatch ). Chisel was best tool but be careful not to puncture through the skin ! Sand smooth when all wood is removed.

In the 1" space you left along the edges, be sure to lay a few layers of extra glass along there to strengthen it.

I did not use relief holes - it's been 12 years ! Still solid as hell !
