Just curious now, are these even available? I looked around on the 'net and didn't see anything but pipe jacks. Too late for me, as I've already started fabbing up a set that will adjust up to ~ 30" tall. I'm building a set that will work with standard HF jackstand bottoms using inverted scaffold jack bases, but will end up having over $120 in the four...

All I use is the 6 ton jack stands from HF.. The have a wide base and go pretty high..

[sedanbob]

To maintain stability, with increased height you should also increase the size of the base. Using a standard base but making it taller, it will be less stable. One easy way might be to weld on a larger flat plate under the legs.

Here is a taller set - more expensive (maybe cheaper somewhere), but the dimensions here will help you figure out how big the base should be - these are 14 1/2" X 13" - the HF 3 ton ones are 7 1/2" X 7 1/2".

We used have some heavy wall 30 and 50 gallon barrels. Pick up a body with the Farm Fork lift we used to stack hay, and it would pick up one end of a car.

Here's mine, extra tall made from an old rear end housing. They measure 22 inches tall. slip them under the rear axle.used them for many years.cost was free!

To be honest, those 22 inch tall stands just look like a way to get a car about two feet in the air, and the ability to move about two feet sideways, as it is falling in your general direction.

Exactly! The Harbor Frieght ones with a stack of 4x12" lumber so you dont extend the stand so far it becomes unstable. I've had my car nearly 3' in the air and could'nt shake it.
Squeeling under a car calling for your wife to figure out how to get it off you sounds like fun.

They are actually very stable on flat ground; then again I haven’t been under them in an earthquake. Don’t think I would like to be under any car on stands during an earthquake….

What's wrong with pipe jacks?

[timothale]

I have an old tree stump with a smilley face painted on it, He's my buddy, He always goes under-neath with me when I am working with jackstands or ramps. We had 2 cars up with all 4 wheels on ramps When the Big 89 earthquake hit in California, I was tired when I came home from work, was lying down, resting in the house and IT shook the car I had been working on and It rolled it off the ramps. I would have been seriously injured If I had been under it.

[gearheadslife]

any big rig parts store (fleet pride/etc) will have tall stands..

[S10xGN]

I've thought about the (in)stability, I may tack weld some 1" square tube between the tops if it doesn't interfere with my work. Or I may just leave the rotisserie's end pieces in place.

Over $100 each is what's wrong, then there's the storage issue. I finished mine yesterday, the inverted scaffold jack base has an acme threaded wing nut that will allow me to fine-tune the adjustment.

I used to work in a boat shop. The rule was we did not go under a boat, not fully on a trailer, unless it was supported by TWO independent ways, each one capable of supporting the boat by itself. Most of the boats we worked on had lifting rings, and we has a pair of chain hoists that used the lifting rings, and we would build a crib or box of longer 4 x 6 timbers to also go underneath the boat.

If you have the rotisserie, it would seem a no-brainer to leave it in place, and also use the taller jack stands in place. I too think is is a very good idea to tie then both together, ideally with a strut going diagonally from the bottom of one to the top of the other.

I have a pair of those, classic. But I have never gotten under a car with them. A bar frame or something, ok but no way am I going to get under a car using them.
