Grape Crusher : 5 Steps

I used lag bolts where it mattered as I didn''t want the weakest part of the frame to be the joints. Even though I don''t anticipate needing a bunch of force to crush the grapes, by using a car jack that can lift 1 ton, screws just weren''t going to cut it. I also built guides to keep the jack from slipping off the 2x4 on the top, and the disk ...

Crumple Zone

For improved crashworthiness, the primary crush zone (also called the crumple zone) is designed to crush progressively with an accordion-type folding (Fig. 10.12) and controlled energy absorption. For a full frontal barrier impact at 35 mph, the length of this crush zone is usually between 500 and 900 mm.
