Okay going out on a limb here... I think I've been making something simple more complicated then it needs to be... When I am building a vehicle using the plans I take the printed plans and wood glue it to card stock, then glue 2 more pieces to the back of that card stock using wood glue again... from there I use my exact o knife to cut it all out. glue it all together.. the problem... shouldn't I be using cardboard?? and is it a simple 1 ply cardboard? corrugated? or the cereal box you find siting on top of the shelf... could someone help me with this?
