I ran a small cnc router for an a exhibit-museum-themed enviroment shop for several years.(Made some sign stencils for freedom poster to protest cynthia mckinney). When i say run....i mean take abstract designs turn them into dimension parts. My crowning achievement was a fuctioning fire truck for miami childrens museum...3/4 sticking out the wall. Out of 3/4 birch plywood. Now the pump system and cockpit and lights came from outside vendors....and I copied the shape from a blown up pic...but it was cool.
One can build VERY structurally sound and light things using 3/4 birch, wood glue, and a narrow crown staple gun.
And i meant to add....there are free, easy cad type drawing programs...which will work with modern router software which doess all the tool path for you.
When i first ran cnc’s....you had to program line by line. It took forever.
I learned how structurally sound 3/4 ply can be when I built my son a bunk bed styled after a castle from plans I found on the internet. The real lesson came when my son grew old enough that he no longer wanted it. Tearing it apart gave me a new appreciation for the word “solid”.
