Well, I've got a lot of projects on the burner and life just threw me a curve this morning. My snowblower threw the rod though the block.
Not having a snowblower around these parts is not an option, Unless you want to work yourself into a heat attack.
$2000 later, I've got a new Toro sitting in the garage.
But that's made some changes to the boat project.
I had planned to make the decking supports from aluminum channel, but now that's too expensive (no scrap dealers handy).
So, I'm going to have to use wood for the sub structure. Not ideal, but certainly workable.
I'll have to get a bit creative with the wood work to keep it light and strong. I'll start with spruce 2x4's and mill the supports and shapes I need from those.
The supports will be milled to "friction fit" in the vessel so I don't have dissimilar metals touching.
If I get a little "fancy" I'll add a few small Aluminum brackets to the boat and use them to tie the support/decking down.
Think: Nylon strapping and buckles.
A plus is that it will all be easily removable.
Since the plan is to rip the 2x4's into 1x1's or less, there has to be some serious rationalization on how they are laid out.
My plan is to use 3/8 or less marine ply for the deck to save weight. I'd prefer 1/4", but that's probably just going to be too fragile.
The plan will probably be to have no more of a 12" span without substructure supporting it.
If I'm good enough with layout of the supports, 3/8 plywood should be plenty strong for walking, standing or....ahem...."sleeping"......which is an important part of my fishing day!
A good coat of fiberglass resin will seal and help stiffen the structure, hopefully without adding too much weight.
Probably going to start working out the layout and cutting support members tomorrow....
