The prop box was made from two plastic milk crates and capped with a
3/4" piece of exterior grade plywood. Here how it goes together:
One milk crate can be left alone. If you inspect the webbing on the
second crate you’ll see that the bottom section can be cut out leaving a
“low rise” crate of about 3-4". My crates had a support rib running
around the perimeter which I left to allow strength when the second crate
was cut down. The cutting process involved nipping all the little angular
ribs just above the support rib. The webbing in the bottom (which is the
landing surface when the crate is inverted) is not strong enough to land
on. To increase strength, cut a plywood panel to “top off” the crate
with. Include four index pins (I used screws) to engage the webbing so
the plywood doesn’t slide off. That’s pretty much it. Using a second
plywood panel you can create a low to high hop for practicing. The boxes
are light and strong. I keep them in the car to hold my loose gear. The
little stack section is good to bring the height to about 15" or so. The
plastic is polypropylene and is slippery so be careful. I have another
video clip called “hop flop” which I’ll put out soon so you can see how
the whole thing comes apart when you don’t land correctly. I grew my MUni
skills on blocks, boxes, crates, boards, ramps, panels and planks. It’s
the best stuff and with a little imagination you can construct
transportable props that are fun to practice on and help you improve.
Have fun and good luck. Later.
