We should make a list of handy $1 items to get at HF when you cannot think of something. Happens to me all the time.

I'll start by suggesting checking if the battery terminal brush is close to $1 on sale or with 20%

Or electrical tape - but only if you can find the old kind, the new label stuff sucks and doesn't even stick to itself (for long).

Good idea avalon, right now the only thing I can think of is the shaprening stone (#7345) but open it before you buy it, most of them are in multiple pieces. Right now it's on sale for $1.99.

The duct tape doesn't stick well either.

These home made jackstands are very strong, I've been using them for years as a backup because I'm paranoid about store bought stands just make sure the post is secured to the base very well and you're good to go.
They appear to be strong, but they will not safely support the weight of a vehicle. The first danger is tipping - the 2x8 is insufficient to prevent the post from tipping over. You would need at least a 24" square base to prevent tipping, and even then, the 4x4 or 6x6 would only safely support perhaps 300 lbs.

Providing a false sense of security can be more dangerous than no comfort at all.

The commercial jack stands are fine. Suppose you are jacking up a very heavy 3000 lb vehicle such as an SUV. The hydraulic jack alone is sufficient to hold the weight, but we use jackstands as a safety backup. Even the cheapest jackstands are rated in the range of 2.5 T or 5,000 lbs per jackstand. In addition, most of the vehicles weight shifts to the tires on the ground. So, if you jack up the front, use two jackstands, and remove the jack, each 5,000 lb rated jack stand is supporting 750 lbs at most, and more likely in the range of 500 to 600 lbs - still 20% or less of the rated load.

I've never heard of a jackstand failure - has anyone else?

Well I plan on changing out the shocks/struts on my 2.5 ton suv - u guys think 4 of those 3 ton jackstands is safe enough?
Yes, absolutely. 2.5 T is 5000 lbs, so you will support 1250 lbs per jackstand, about 20% of the rated load for the jackstands.

Make sure the jackstands are sitting level on a solid surface like concrete. Jackstands on the dirt ground or asphalt tend to shift and sink in, due to the load. Jackstands and hydraulic jacks are designed for use only on concrete surfaces.

Lol a PT 4x4 can only support 300 lbs? I think you are mistaken. My companies warehouse has stacks of drywall in excess of 30,000 lbs sitting on top of yellow pine 2x4 spacers. The tire men who change the tires on our peterbilt's will at times use a block of wood to support the axle while they change the tires.

The only way I can possibly think to snap a pt 4x4 with 300 lbs is if you have it suspended over a wide gap and apply that force directly to the middle. Even then you might have to get it started with a saw cut


Not to mention a number of years ago I had my nova sitting for 6 months on pyramid stacked foot long sections of 2 x 4 while I was saving money for the parts I needed. I think wood is a acceptable material capable of supporting far more than 300 lbs.

It's important to note that in all the examples you give, nobody is actually going under the objects being held up by the wood. That being said, what's the risk if the wood actually does fail in these cases? Inconvenience of having to pick the load back up off the ground? Maybe a little bent steel? Not a huge risk in my book.

I have no problem using stacked wood as a backup to real jackstands, but I don't make any decisions based on the assumption that the backup will keep me safe. Wood is much more susceptible to movement and point-loads than steel, but I'd rather have my falling car supported by a stack of boards than my skull. I sometimes use cinder blocks, spare wheels, or even ramps as an extra safety measure. As I said before, I don't make any decisions based on the assumption that these measures will save me, but it just might make the difference between life and death.

12gauge, there's no need to justify yourself. You're taking an extra safety measure that many do not.

There is a HUGE difference between using the side grain of a 2x4 or 4x4 as a support, in a configuration that essentially cannot tip over, and standing a 4x4 on end to use the end grain in a very "tippy" configuration.

If we engineers are "mistaken", why do you suppose that building codes don't allow the load levels you suggest on decks, and require 24" diameter footers?

"Guessing" at the load and design of timber heavy support structures is likely to get the car damaged or the person injured. It's far better to use the relatively inexpensive commercially available jackstands that have been designed for and tested to comply with their rated load limit.

Decks require large footers because the footers are being placed on top of dirt and the weight neds to be distributed over a wider area to prevent sinking. The floor in my garage is concrete I'm not worried about sinking. Also I'm talking about posts maybe 1 foot tall not 4 - 8 feet tall like you see on decks.

And like I've said in previous posts I use these in addition to standard jackstands. I don't trust what they are rated for, they only rate a few stands then they trust the chinese to maintain the same production quality.

That is part of it, but the tipping factor as well as frost upheaval are primary reasons for spread footings.

FWIW, the accepted minimum design standard for soil is 2500 psf - so a 24" dia footer can support a minimum of 7800 lbs, without requiring soil testing. Given typical deck load ratings of 40 psf, that's about 200 square feet per post. In other words, the load of a typical 10x20 deck under these conditions could be supported by a single post. However, if the post is not properly end-bolted to reduce tipping, that same post cannot support even a tenth of that.

Whatever, just please be careful - I'd hate for anyone to get hurt.

If you are really concerned about the jack stands, you could test them. Use your HF 20 ton press to push down on the jackstands and confirm they don't fail.

New parking lot sale coming up august 25th

The flyer almost looks like a reprint of the last one.

I do see the jackstands in it for $15 without Q, so this would be the lowest price of the year ($12)

Oh I found another 40 cent item instead of tape, get a mini steel brush for 50 cents - 20% Q

I'm getting tired of getting meters though, I like getting meters because it has the highest list price ($10)

I wish I could get a lighted meter, anyone wanna trade four meters for a lighted meter, lol

In those no..

Is your house made of wood?

just mixing the pot Wink

I have used chunks of log for a jack stand when nothing else is available. Figure that is better than nothing.

I'd still say use a proper jack stand when you have no reason not to.

A few years ago I treated myself to a 3M heavy duty duck tape at lowes, I think I had some kind of Q - I will never use anything else, this stuff is amazingly good. The problem is I am almost out and it's crazy expensive now. Wish I had a time machine.


I've heard scotch super 88 electrical tape (another 3M product) is also the best you can get, but expensive too.
