Doesn't mean its right.

Doesn't mean it's completely wrong either. Nobody goes under it, it's not mean to serve as a lift, merely something to hold it there so we can take the tires off for the winter. Then put the tires on, jack it up high enough to take the blocks out, and that's it.

Insurance company would beg to differ I bet if something happened.

Ughh I thought cinder/concrete block tech was commonly know. Never stack the blocks ANY way other than the face youd see them in a foundation.

I found this out the hard way at my buddys house. He threw a block under the back of the truck and mid axle drop out it let go. The truck was teetering on the 3 jack points that remained with me under it. That was scary...

The compressive strength of concrete is around 4000 psi. The compressive strength of cinder block is around 1250 psi.

With a car or especially with a truck, you can get close to 1250 psi. Figure the weight is spread out but comes to a point at each wheel. If you throw a cinder block under a rotor(!) or something like that then the weight gets concentrated.

Skip the block. Do it the right way.

Get some of these!

I can figure out stuff with these. LOL

Or you guys could avoid this whole arguement by spending 30 bucks on some jack stands instead of trying to prove who's the smarter professional jerry rigger.

They would spend more than the cost of a jack and jackstand set on materials to set up their hack ass setup.

how did it get the name, "jackstand"?

What help will a hole do if you have to do any other work where you have to take the load off the wheels? Or remove them?

Hey, If you want to run around here and make great and valid points, do it in another forum. :lol:

exactly...you would pretty much only be able to do oil changes and basic fluid maintenances. Those holes were mainly used in quick lube shops where cars can drive in and drive out as fast as possible.

A set of some good jackstands would be much more convenient, probably cheaper than all building materials for the hole. When your done just put them off in the corner. No hole to dig, cover, or do whatever with. And then you could even pull wheels

Not to mention you will probably get **** from homeowners/property owners insurance for having a hole in the ground with no fence, etc. The last thing you need is for a neighbor's kid to fall in.

And since the subject of under car maintenance has been brought up, don't forget to purchase some wheel chocks in any case you don't need four wheels of the deck. Should go without saying but I'm saying it anyway.

Now that you could use a brick for!

:)

Yes, yes...I've used the a couple of bricks on occasion.

I didn't think jack stands were that expensive.

chalk breaks, chocks dont!

but you could've at least spelled it right. it's "chock" as in wheel chock, to chock a wheel to keep it from moving. and regardless of the wheel chock used, you should also set your parking brake and/or leave it in park or a low gear (1 or 2) for a manual.

i have used any number of things in a pinch. i like big, round things to put under the wheel after it's left the ground. like a spare tire with a steel rim in it. the bigger the base of the 'jackstand', the better. those 6-ton stands are way overboard, but the height of them might come in handy. i'd like a set, but i be broke.

yup. thats exactly what theyre good for

Hmmm come to think of it I believe I've been using cinder blocks but I always double them up when I put them under my truck, so 2 wide = 2500psi I take. And I never put anything sharp or small that concentrates the weight to a small surface area, plus always have a 2x8 chunk ontop for best distribution.

I just go to work and use their lift...for free

Yey! But not everyone is that lucky.

:shifty:


i wouldn't call it lucky......maybe i would.....:D

Some of us are luckier, we have a lift in our own garage.:wink:
