Are the timbers actually 4 inches x 2 inches or is that a termination of

stand is about 22 inches high?
how far in from the edge is each corresponding level?
Held together with what (glued with dowels, screws or nails)?

Well I figure the best way to do this is with a photo album (thanks bdub). See here:
http://www.gmcmhphotos.com/photos/showgallery.php?cat=5461
Background - I had a car, my Corvette, fall off jack-stands once. Fortunately I was not under it at the time as it would have been uncomfortable, but not fatal as I always put the removed tires under the frame. The part I do not like about conventional jack-stands is the metal pad on the top. That pad has no traction on the frame. I see many photos here of GMC's supported on two jack-stands with a slope on the frame. I feel this is just asking for the jack-stand to squirt out because that is exactly what happened to me with my Vette. Another part I am not comfortable with is the relatively small area of the base, especially compared to the height. After my incident I gave some thought to a better jack stand. I came up with a design using 2X4's that was extremely strong, proven by a trip to my 12 Ton shop press, had a wide base, could be made any height, had a wood top that will grab whatever is being supported, and as an added benefit, is very economical, it even can be called cheap (a set of 4 is less than $20 or so). It can be made any height. The only disadvantages is they are not adjustable (more around this in the photo album), and they take up a lot of room to store although they do sorta stack.
Peter - you will find me listed as midlf on the GMCforum and the photo album. That's my email address. I've found if I'm looking for someone to also check for them that way.

Steve,
Thanks for information provided and I can see from your photos the simplest
way to build this is to start with the level that has two pieces together
( at a pre determined length) and with each level being an 1" longer and so
on and the ends level on one side with the corresponding piece of the level
underneath sides thus creating a strong construction (like brick laying) and
that governs the gap size between timbers for each level. When viewing from
any side every other level has the timber end pieces showing. to add to
height each level increases the base width.
Have to make sure they are stored to avoid termite damage or probably make
them from treated timber, that's how bad white ants are in our area.
I was looking through some of your postings for a clue to a username but
could not find one, and I was correct in my thinking as you have now
supplied that. Ta !

Peter - The easiest way to build them is to start from the bottom with the longest pieces, space the next ones one inch in from each side, glue and nail them and repeat. If you do it "upside down" you will not have a firm backing for nailing. I use a carpenters square to make sure I am on track as I go. The alignment of the lowest level is critical, after that it just sorta flows up.

I'd go with treated, just have to wear the respirator while cutting and gloves while assembling. When I make a set for the transmode parts coach they will be treated 2X4's with a treated 3/4" plywood base or I may use some 2"x8"x4' treated planks under the jack-stand. The enhanced base will be to prevent it from sinking into the swamp muck we have for soil around the barn.
For the user name it is in the heading on the forum or as the email address on GMCnet.

The CFO reminded me that she had taken a lot of pictures of the process of building these jack-stands the last time I made some. I'll get those put in the album later today.

Steve,
So if one would require it taller then the
base would have to be larger as I said so the height one would require would
have to be determined before you start building.
Peter Bailey

Well I think there is a reasonable limit to the max base size needed. At 16" the base is large but not too intrusive into the work space under the vehicle. I had kind of decided that 16" was as big as I needed if I was going to go higher with the limit being 6" or 8" higher. Of course using a floor jack there is a limit as to how high you can go.
However to answer your question, yes you have to know how high you are going to determine the base size and thus you have to know that before you start. You could add on a layer later I suppose as it is not impossible. See my pictures for how I added a few inches with blocking. I feel that I can safely add 4 or so inches using blocking as shown. With a GMC's very flat frame and 1 ton on the jack-stand the blocking isn't going to move any.

Steve,
Great design! I think I'll build some for my coach. I've been wondering what I could use on this soft soil I have around here.
Peter,Once you have built to Steve's design, you could always add height to the bottom, using screws and glue. Just keep on going up as high as you need. It seems that the more base you add, the more stability you have. You just create a larger footprint. [Right Steve?]

Right - I think the reply to one of Peter's posts has the full answer to this question.

If anyone wants a copy I have an excel spread sheet that has the cut schedule for making 4 jack-stands from 8' or 7' 2x4's. It can be easily modified for making 6 jack-stands. BTW it takes 8 8' 2x4's or 11 7' to make 4 jack-stands.
If you want a copy of the spreadsheet send me an email
midlf
at my ISP (replace all of this with @ )
Centurytel.net
and I'll attach the excel file in the reply.
The additional pictures I'll put in the album later tonight are step by step instructions on how I do it.

Steve,
Your pyramid stands are great! Just thought for those that want to take it
to the next
higher level, would you recommend using 4x4's for the bottom and/or top
rows? this would increase the height another 3 inches if using 4x4s top and
bottom yet would not change
the footprint. As mentioned earlier - often increasing the foot print
restricts access to undercarriage components.
Just a thought,

I would have no difficulty doing it that way. As you can see from the pictures I went an extra 6" just using blocking on the top of the Jack-Stands. It all really boils down to what ever you are comfortable doing. You have to decide for yourself what is safe. You could also just increase the length of each level by less than the 1" I used and it would give you height without making the base too large. As I said in one of the picture descriptions the height was determined by my floor jack and doing the stackup the way I did gave an acceptable, to me, base width that was wide enough to satisfy my safety concerns without being so large it interfered with my workspace. I most always had acceptable workspace on the Vette, and certainly do on the GMC.

Steve,
I'll be making a set of four for the rear. Under the front tires I use a
set of Snap-On alignment
stand. Like all S-O stuff it is really heavy duty. The downside is that it
only works with the wheels & tires on.
I had a set of those 3 ton Harbor Fright ratchet stands I used to use under
my MG, until one day after setting up one stand and jacking up the other
side the car came crashing down. The ratcheting edges and pawls just didn't
hold. Last time I checked that MG was not that heavy.

I have had a block of wood split under my 66 Nova. I no longer trust wood as a primary method. I do use wood cribbing for secondary protection under the bogies or the front tires.
I like the 3 ton jack stands from Harbor fright. they are thicker and wider than the usual types. The "L" shape of the bottom of the jack stand legs also bite the concrete which gives me piece of mind. These also fit the front cross member of the coach nicely, and you can put a thick rubber sheet for some grip at the top.
They also stack nicely on their sides on top of my floor jack.
My two cents...

I will agree on a single block of wood being unsuitable for the reason you noted. It can split and shift. I feel the multiple layers of my stand get around that, sorta like plywood vs a plain board.
As far as HF stands I've copied and pasted a bit from a previous post:
"I had a set of those 3 ton Harbor Fright ratchet stands I used to use under
my MG, until one day after setting up one stand and jacking up the other
side the car came crashing down. The ratcheting edges and pawls just didn't
hold. Last time I checked that MG was not that heavy.

If I had these I would inspect and, if necessary, clean up the ratchets and pawls with a file to make sure they had good bite. With the inconsistent quality of Chinese goods you may have a better set than Tom had.
Chris - check the swap section for my answer to your request.

Chris,
These were brand new Harbor Fright stands. I still have them - they are
useful for holding up a rear axle assembly. Only thing nice about the 3 ton
HF stands is that they have shiny enamel paint. I think the quality of the
HF stuff varies do to the different suppliers they may have. Some are
probably better then others. Raise the ratchet and give it a good smack to
make sure it is safe.
I also have an older set of 5/6 ton ratchet stands - also made in China -
very solid and stable. Use them all the time under an F150. Use to use
them under a 1961 MK IX Jaguar saloon - about the same weight as a Rolls or
Bentley, but that was before the D-I-V-O-R-C-E - sigh - for the cars - not
the divorce.
I will check them and see if the edges can be ground a little - just got
apprehensive after the crash.
I think we're up to 4 cents now,
Tom Eckert

Tom / Steve,
THANKS!
All the Harbor Freight stands I have here in Australia are at least 8 years
old as we retired here in 2002. To date they've never dropped BUT since you
have noted this I WILL inspect them closely and whenever I use them I will
make sure the ratchet stops are fully engaged!
I did buy four three ton stands and four twelve ton stands from HF for
Double Trouble last year. I REALLY appreciate you calling my attention to
the problem you had with your three ton set. I've put it on my TTD list to
inspect them carefully when I get back there in June!
Looks like even the Chinese "don't make 'em like they used to," eh!
As far as your stands that collapsed I would take them back to the store you
bought them. Bring a friend with you to witness the conversation and tell
the manager what happened. I would be most surprised if he didn't take them
back and give you a new pair. They are defective, period, end of story!

Chris,
These were brand new Harbor Fright stands. I still have them - they are
useful for holding up a rear axle assembly. Only thing nice about the 3 ton
HF stands is that they have shiny enamel paint. I think the quality of the
HF stuff varies do to the different suppliers they may have. Some are
probably better then others. Raise the ratchet and give it a good smack to
make sure it is safe.
I also have an older set of 5/6 ton ratchet stands - also made in China -
very solid and stable. Use them all the time under an F150. Use to use
them under a 1961 MK IX Jaguar saloon - about the same weight as a Rolls or
Bentley, but that was before the D-I-V-O-R-C-E - sigh - for the cars - not
the divorce.
I will check them and see if the edges can be ground a little - just got
apprehensive after the crash.
I think we're up to 4 cents now,
Tom Eckert
