anyone ever made/used wooden wheel cribs?

[Short Norman]

Anyone made or used some of these before

not sure I'd trust them myself but they seem to be popular in the states

Not made any but wouldnt worry about working under a set, 3x2 timbers stacked like that will be solid.

Id be more concerned getting the car up to height with a normal jack, can be sketchy

Not me thinking this was a baby's crib thread. Never heard of that term for Jenga.
