How to use a CNC Router to build a simple 6 board chest out of a 2* 4 foot quarter sheet of ½ inch Birch plywood. I did it at Techshop!

This is my first Instructable so please feel free to leave any constructive criticism in the comments, thanks!

What is Techshop? follow this link!

These chests are useful as small toy boxes or other storage, they are the perfect size to sit upon, and plenty strong.  I use them for storage when camping at medieval events in a History reenactment lite group i am in called the SCA. These boxes are good for almost all periods of historical reenactment because their simplicity kept them in use for a very long time. Because you can sit on them they make excellent feast boxes

Because they are nailed and glues they are plenty strong to use to sit on as well.

You may use these plans and modify them for any non commercial use. you can't use them to make products for sale without my prior written approval.

What you need:

Membership at TechShop or access to equivalent tools, and basic knowledge of how to use them.
Cnc Router(Shop Bot)
Nail Gun with Plastic nails (or other holding device for CNC Router)
Nail Gun with Regular nails (for assembly)
Wood Glue
400 Grit sand paper (and some way to use it, I used a Random Orbital Sander)
Pre stain wood conditioner(photo)
Wood stain (photo)
Spar Varnish (photo)
1 or more 2’ by 4” sheets of .5” (1/2”) Birch plywood.
Razor Knife for cutting off the tabs on the wood after cutting

Why do you keep specifying Birch Plywood?
I specify birch plywood because the added veneers make a nominal half inch thick sheet, actually a half inch thick, unlike other Plywood.  The Illustrator file I Provided is designed to work with any material exactly a half inch thick, experiment as you desire.

If the quarter sheet you pick is significantly smaller than nominal (2'*4') you might have issues,  I believe the pattern has 1/8" of slack along the edges farthest away from 0,0 on the router.

If you don't have a router  you can look at the plans and copy the dimensions and cut one out by hand. I made quite a few of boxes similar to these using a saw and a router instead of the CNC tools at Techshop.

My goal in this is to make these boxes available easily and cheaply to lots of folks.

A quarter sheet of .5in birch plywood costs me about $14, the hardware can cost as much or little as you want, you can skip the latch, and just nail small pieces of scrap leather on for hinges, use scrap rope for the handles, use stain you have around and this box could only cost you for lumber... buying hinges and claps will easily double the cost, but it looks so much nicer.
