And a sort of sideways view of a load of scribble of what im
going to do with the tub sides... definitely going to need more
plywood...

Heres a pic of what a Shaker Weave is, courtesy of the rocking
chair; a wooden rail framework made of beech broomhandles, 25
metres of black ballistic nylon tape and an industrial staple
gun = traditional craftsmanship with hundreds of years of
tradition, innit..

I think im going to have to build some sort of table to jig this
thing up for glueing.... the farm cottage we live in is 300
years old, there isn't a straight line or flat surface anywhere
in the house, never mind somewhere with enough flat space to
laminate something 8 feet long on....

If it's any help, I have made a table up from galvanised tubes
and key clamps I got from the Metal store. You can then have the
feet on any uneven surface, and level the top. It's what I'm
building the Morgan on. When finished it can just be all undone
and stored till the next one. Cheapish too!

I have found that a good solid wooden bench top would be a door
blank, you can get them 7x3’ or 8’x4’ usually flat, also
sometimes the likes of Howdens joinery have a damaged one that
will sell a bit cheaper.
It looks like you are building along the same lines as I am. I’m
going to post my progress later today.

I wandered down to wickes and bought an 18mm 2x8 bit of
chipboard and 4 bits of 8 foot 2x2 pine and made a temporary
bench/jig/datum plane.. itll warp sooner rather than later with
the current weather but as long as it stays straight till about
wednesday im happy. I glued up the first 3 laminates of one
side, its come out pretty well, now drying overnight indoors in
the warm. I hate to brag but with 2 laminates to go its already
very stiff...( sorry) ;c)
I also did a load more on the seat, im pretty pleased with it so
far, its pretty comfortable. Im doing a curved back on it, we’ll
see how well that goes!
Tomorrow im going to glue the other side up, trim both rails to
finished dimensions, build up the tub sides, finish the back of
the seat, drill a million more holes in everything and buy
several more dozen boxes of screws and then hopefully ill have
the best part of a composite monocoque racing car chassis
sitting in my garage by about wednesday...
Apart from the glued up rails everything else is being dry
fitted for the time being. Ill glue it all up and start playing
with glass cloth and epoxy in a couple weeks.
Ill try and take some pics in a bit, im being pretty lucky so
far this evening and missus Synthpunk hasnt quite fully twigged
yet that theres a half a small racing car chassis sitting in the
front room. Surprise!! ;c)

Pic of the seat - xtra bracing in the bottom, bracing in the
back, the beginnings of the curve... and probably over a hundred
screws..the side rails are all screwed and glued using
countersunk 16mm size 4 screws.

Heres a closeup of some laminated wood. Because the rails are
glued up from 6mm ply to make a solid run of at least 24-36 mm
that runs the length of the car (the rails and tub are full
length, and the outer laminate extends to the front but not to
the back) so the suspension horns at the front are an inch and a
half/36mm thick, and at least an inch/24mm thick everywhere
else.. also, a 6mm ply is made up of 3 lengthwise grains and two
vertical ones, so in an inch thick you get 12 length wise and 8
vertical, so its stiffer in one dimension by about 25 percent
than a piece of ordinary 1 inch ply, which would just have 1
extra lengthwise ply.
Pretty isnt it? Its all going to get hidden under a layer of
epoxy glass, 2 pack epoxy truck bed paint and then some white
rattlecan paint. Hooray!

And before i forget heres a pic of the seat so far. I had to
replace some of the previous battens because they broke when i
was experimenting with bending plywood. Its now been replaced by
much beefier 1.5 by 2.5 inch pine, and many many many screws.
