I’m not sure how this is going to work out online, here is the second Chevy in my plywood line up, in a much simpler layout, but just as reliable and very strong.
Birch Plywood is an ideal medium to use for this kind of project due to its multi layered higher density form, but you could use good quality exterior ply which is slightly cheaper if the former is unavailable.
First pictures straight out of CAD gives a view of the basic outline of what are basically a pair of side boards in Birch plywood at 3/4” or 18.00mm thickness here in the Uk. There are additional cut outs to be removed from the boards, so I will add shots of where these are situated later.
When creating any cut outs in the boards, make sure to pin them both together and establish a squared off corner and face edge to work from and take all your measurements from, this will ensure a matching pair for assembly later, don’t trust the manufacturers edges when purchased, measure twice cut once.
Picture above show a 3D line drawing of a tumbler, which can be made in aluminium or steel. Top hole is 10.00mm, bottom hole 14.00mm, body section 25.00mm by 20.00mm. Holes are 50.00mm between centres.
All sizes are marked in centimeters unless stated otherwise.
The new PW2 will incorporate a front closing vice as in the traditionally orientated Chevy with a manual quick locking cam/mech to hold the vice closed mid job, so you can leave your seat with the pack held firmly in situ.
As we progress, live photos and ammendments will be added where detailed assembly is needed.
First amendment to the side boards in blue screen, to allow a deeper pack to pass through, the pack gap is 4.5cm, the beauty of this design is the shaped can be drawn directly onto the plywood and visualised before cutting begins.
All constructive comments welcome.
