"Steve Southworth,
Tried to find you on the members list but couldn't, I wanted to send an off
net message as I felt that I would be hi jacking your original post but I
now have to , I want more information on making jack stands as you have
shown as I don't like the metal stands that I currently use< i fear one day
they will release and down the coach will come, like you if I have a wheel
off it goes under the frame in case of.
Are the timbers actually 4 inches x 2 inches or is that a termination of
something close, meaning the base is approx 20 inches square and the overall
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)?
Regards Peter Bailey"

Well I figure the best way to do this is with a photo album (thanks bdub). See here:

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.
