more affordable jack stands

this is on e-bay really nice jack stands like the safe-jack ones but half the price I just got 2 of them today and they are nice heavy duty and perfect for our corvairs you can buy 2 for less than 1 of the safe-jack ones [www.ebay.com]

My name is Mike Worrell living in southern Iowa my vairs are a 64 2dr convertible monza 900 with 110 motor 4 speed light yellow with blk interior. Then a few months ago I got a 65 2 Dr convertible monza 900 with 110 motor 4 speed
Also light yellow with blk interior. Not sure what gear ratio as of now I'll have a look and up date. I really like them both but really liking the 65. They really made a lot of changes in a 1 year difference ????

Maybe you need these if you have a Tesla. These look to be too big, too complicated and too expensive when standard jack stands work just fine and cost 1/2 as much or less.

When I built my 49 Chevy Fleetline I jacked it up high, put two 8x16 INCH Concrete block on each side, I also put a 2X8 pressure treated board on top of the concrete block...(just like what holds up a HOUSE! that weighs just a little more than a car) and this Chicken feels complete safe. I did my 66 140 Corvair like this several times. Those saying concrete block is dangerous is B/S. tHE 2x is the safety factor...no sharp metal to cut block.

Each of these blocks are designed to hold 1900psi EACH...two of them plus the 2X would equal over 4,000 pounds per side that I use. cost= $1.65 each, 2X8 to put on top of the block...about nothing.

I assume you use four of these otherwise you wind up with a possibly front/back teetering car? The width alone (two per side) looks like it would inhibit side entry to the underside of the car.

With shipping and tax (seller is in the same state as me) it would be $296 for four. I'm not seeing that as affordable. And to think I pick up regular jackstands at garage sales/thrift stores/swap meets for about $5-$8 per set. The last set of two I got from a Habitat for Humanity Restore Store were 70's era USA made and were $5 for the set. Properly placed I have no "safety" issues crawling under the car.

Using cinder blocks as jack stands is how people die, its a know'n fact in the car world, go to any car forum and you will find the same answer! Cinder blocks can and will crumble and kill you, when they hold up a house they are filled with rebar and concrete. Heck Karate guys break them with their bare hands for show! If your life is only worth $1.65 go ahead and use them, I will use over sized approved automotive jack stands.

I've never actually seen a cinder block but I have had concrete blocks break while holding up a car back when I was a teenager.

If you have ever noticed how overpasses are built and supported during construction. Can you say that you ever saw cinder/concrete blocks used a support?

I sure have never seen much but Heavy Timbers and or steel used for support during construction.

As both Joel and Dave noted: Concrete/cinder blocks can fail with no warning and fatal results.

I have 6x6 and 6x8 wood blocks to backup my jack stands.

If you need tall go to taller truck height standard jack stands. They should not be used on top of anything except a solid surface like a concrete floor. If you need taller still get a lift. Truck height stands are plenty tall to get the car in the air and clear a powertrain or suspension in and out, as well as roll around under the car on a creeper unless you are short and 300+Lbs maybe.

VERY FUNNY!!! Not very educated however. How many houses have you built? Are you a GENERAL CONTRACTOR rated to build both Residential and Commercial? well I am!!! How high can you build with Concrete block without rebar and concrete reinforcement? sAY 35 FEET. Do you know what 1900 PSI means? How many POUNDS with that rating spread out over 16 inches....GOODNESS...what an idiotic remark you made....moronic in fact!!!

What you guys are talking about are MORONS working on their car...turning the block up on its side..then yes and maybe ...that would be scary and I would be the LAST PERSON ON EARTH to be that STUPID. The strength in a concrete block is using it as it was designed (to support 35 foot tall walls and a 30lb snow load here)...with the 16 inches on the ground.

Dave you are SO WRONG about you have to use concrete and rebar when you build a house....LOL...you should NOT BE giving advice TO OTHERS when it comes to building. Maybe in a earthquake area that might be a requirement but that is not for holding up a house..that is because it is subject to being shaken to death. I had to use rebar and 8X12X16 block with cells filled with 1/2in rebar in every other hole all the way around the foundation but in the front of the house 8in block, NO REBAR, NO CONCRETE PUMPED IN ANY OF THE BLOCK...10 foot walls and the front was a load bearing wall. And here in the mountains, we have to build for a 30lb per sq in SNOW LOAD in addition to all the house and its contents..

Why did I have to use rebar in every other cell and pumped concrete in all the cells in 3 of my 4 walls 10 foot high ??? Was it to support the house....NO NO NO NO. It was because I was backfilling the house on 3 sides WITH 9 and 1/2 feet of dirt that pushes in on the block...

Here is a little education for you Dave...mY best friend called me from work one day and said...you want to buy a 56 Ford pick up for 600.00 that runs from a female worker here? Yes I said. He then told me that her husband had died and she wanted the truck gone. He was working OUTSIDE WITH JACKSTANDS in the dirt on a chevy truck and the work site was almost perfectly level ...you could barely tell it had a slope when I went out to buy the truck...he had shook the truck installing the rear end and it fell on him. "JACKSTANDS" are very unstable...don't believe me...put a car on 4 jackstands and shake the car sideways...dare you. Long story short... had he had THOSE $1.65 concrete blocks....and I would have not have been able to buy that nice 56 Ford pick up he would be alive today.

READ A BOOK !!! GET SOME EDUCATION. Stay with corvairs...otherwise you are WAY OUT OF YOUR LANE. If you need more education...feel free to PM me and I will give you my phone number...GOT IT !!

Were the concrete blocks turned up on their side or correctly used? What was their condition?

Just for your information....overpasses are different from buildings or cars.

Sorry for trying to save lives.

If saving lives offends you, I'm sorry.

Yes a concrete block (CMU in today's talk) can support great loads, no argument there.

But there are people killed by cars when CMUs fail.

Have you ever seen a flaw in a CMU? I have. The strength of CMUs comes form "safety in numbers". A small flaw will be not be noticed because there is another CMU to take the load.

Now, place one CMU at each corner of the car ( I see you have wisely used wood as the interface between the CMU and the steel sharp edges. That alone eliminated a lot of danger of CMUs vs steel sharp edges) and have a small flaw crack one of the CMUs. Now, how do you feel holing the corner of the car with your chest?confused smiley

That's all it takes. Now, build a wall of CMUs and a wood top plate and I will get under there with you!thumbs up

Yes, I am a contractor. Yes, I am an engineer and can do the calculations to see how much weight a CMU wall can hold , or use the prescriptive tables.... But, no way will I trust my life to ONE CMU!

Single point of failure is not a good way to go.

Now, you also bring up another good point, that jack stands are only for use on proper substrate. They will easily sink into the ground, and while doing that twist and have the vehicle fall off of them.

When working on the ground, I use my small platform framing sections. Good resistance to sinking into the earth, and several "floor joists" so no singe point of failure. What I made are 14 1/2" or so square 1 x material nailed on top of 2 x 4s or 2 x 6s 14 1/2 " long and those are on similar 1 x material on the bottom. Like a cross section of floor with subfloor on top and a ceiling on the bottom. Add end brace so the joists will not fall over in unison!eye popping smiley

No matter what one uses to hold a vehicle in the air, they should understand the danger and make wise choices.

When I was 18 years old my dad and I were working on my car with jack stands on dirt. The car shifted, fell and the brake rotor crushed my father's face. I lifted the car off my father and rushed him to the hospital. After that day there will always be two different safety devices holding up a car that I work on. Thank God he only needed stitches.

Yes, they were the correct direction and there were no visible flaws. Granted there must have been flaws.
