Does anyone know of a source online for plans, photos, or drawings of
shop built full extension drawer slides?

I'm designing my shop carts and need to add drawers for holding bits,
screws, etc. The drawers will be on both sides of my 24" wide cart so
will only be 10" deep. Can't find metal drawer slides that short plus
the closest I've found are $10-20 each and with 16 drawers that's
going to cost more than the wood I'm building the cart from.
