You guys and the wood lol.

Listen they use Woodblocks to hold boats up on dry dock... and they use wood blocks to hold 80 ton tanks up in the air.. Wet wood doesnt compress.. Maybe if you were using a dry rotted peice of 2x4..

Go to about 7:10 on this video to see the use wood to hold the tank up..

And they're careful about the shape of the wood and orientation of the grain, believe me! What driveway wrench can say the same thing? For the most part, we're hobbyist mechanics, not engineers.

Wood is an excellent engineering material - strong, light, and easy to form. However, it's also PAINFULLY easy to screw up with!

I'm familiar with the myriad uses of wood in engineering - from Balsa to lignum vitae. I'm also familiar with how it's designed and engineered when used - you don't think they just just any old wood block to hold up tanks or ships in drydock, do you? Or that they just run down to the Home Depot when they need more? Trust me - most of the stuff you find in the hardware store is rejects from high-strength engineering uses, or stuff that they know would be rejected, so they didn't bother to submit it!

While I agree that the wood could be dangerous on the stands, as long as we are talking wood and heavy stuff how about trains and railroad ties .

What they are using is referred to as "blocking & cribbing" along with a hydraulic ram. I was trained to use this method and is no way the same as sticking a piece of wood in between the saddle and load. You should never alter a jack stand in anyway. If you make the saddle wider it can cause the jack to tip over...even if you weld a plate underneath it.

Just put the Jeep on the jack stands. Even if it's resting solely on the "tips"... you'll be fine. So you might get a couple little "dents" in the frame rail, but it's fine. Use some good judgement. I, like another poster, shake the vehicle once on the jack stands to check for stability before crawling under. I also put the tires under the vehicle just in case.

Also make sure your jack stand base doesn't sink into whatever it's placed ON...

I had to laugh about the comment, "put it up on the stands and shove it, if it doesn't fall off, it's safe." So, if it falls and gouges the crap out of the doors, it wasn't safe and really dorked up.

Be careful, do it the correct way.

Better to dent your jeep than kill yourself.
