I do agree on the height issue though, would need to be at least two blocks high... |
See, it's all in the execution of the plan.
And the reality is it is nearly impossible to properly execute blocks with voids under a car safely. You also grasp the point its about load distribution. Problem is under a car is rather un-flat, lol. So it is hard to spread the load evenly across the block, say like in a house foundation.
You just can't say it's ok to use blocks with voids under a car w/o a big disclaimer. You have to remember there are a ton of users on this site that are very inexperienced and all they will see is 'it's ok to use blocks'. Nope, it isn't for the reasons given, unless they go to great lengths. Given the safety aspect of the issue at hand (see the crushed by Jeep thread), it is waaaaaaaaaaaaaaaay better to just say "no" than to try to explain the details involved in "yes, but".
I know you hate hearing about actual experience, but my Dad was a cement block junky so I have more experience with them than I'd like. I've seen them break out of the blue. And I know other guys that have seen it too. Better to be safe than dead or paralyzed.
