... I would urge you to scribe water
and buttock lines (horizontal and vertical "slices") permanently on the frames. Scribe the frame number on each frame where it can be seen after plating. This will make your fitting out quicker, easier and more accurate.
You could also drill as many mounting holes as possible in frames before erection. If you do this in the overhead stringers as well you will save hours of convoluted "exercise". Use a drill press.
I have found the tricky bit in fitting out to be getting the longitudinal base mounts of the interior
cabinetry right. If you can do this before plating it will make the whole job go much faster.
All frames and longitudinals need limber holes and placement so that all interior
water drains freely to the bilge
. This is best done when making the frames and installing the longitudinals (i.e. before plating).
If you weld mounts for the cabin sole
onto the frames before erection then you will be able to put cheap
ply down as a working area (use good thick stuff). It is very easy to trip and fall down inside a boat shell and there are lots of sharp edges everywhere. It may be possible to weld longidudinal mounts for the interior cabinetry between the sole mounts before plating. Don't forget to drill bolt holes at this time.
My woodworking skill are well below what I would like so I have gone with Bunning's ply (NZ "Ecoply", "A" bond with hoop? pine face veneer) and structural pine noggins, saturated with epoxy
where necessary. Many may sneer but I feel much better when I have to rip something out and do it again, my bank account really notices the difference and I am happy to do a quick job.
If you have a look at my blog you will see what I have done. Artistic awards gratefully accepted.
Bunnings will cut to size for a modest fee. This means that you always have good straight edges at right angles to each other to work with (and I can get the bits to fit in my car).
I would urge you to think carefully at this stage as it is possible to get a hull
to go together very quickly but to then be faced with years of difficult fitting out.
