Subject: <E36><E36/5><E38> Lets Jack it Up, My New Jackstand Adapter
As posted earlier last year, I designed an interface between my car's (E36)
disc shaped (hockey puck like) lifting points and my U-shaped Sears
jackstands. The interface bolts to my jackstand so I can remove it, and
continue to use the stand as before. The Sears stands are no longer available.
The following is the new idea.
Pay particular attention to the following words, in respect to SAFETY.
Based on a desire for a shorter stand, and some outside interest, I've been
looking for a replacement stand. I finally found a economical jackstand that I
can easily add my adapter to, with some modifications to the original design.
The stand is a four leg 3 ton / PAIRED double pin unit with an 8 1/2 inch
footprint made by Tru-Cut (An American company). They sell for $18.99 per pair
at PepBoys and other places through out the United States. They are not a
Lincoln quality stand, but neither is the price. Connect to their website:
Be advised that Tru-Cut states that ANY MODIFICATION to there stand voids
there liability. I designed the cupped adapter to increase the safety factor
for my E36's. The Tru-Cut stand has a 1/2 inch hole sort of centered (offset
0.030 in the length dimension) in the support area, which required another
machining operation to accommodate this offset. Its 8 3/4 inch square
footprint will allow the use of Steve D's jackplate adapter without getting in
the way of your floor jack. I use Steve D's jackplate when I want to get one
wheel off the ground and on a jackstand.

Its just easier than going underneath and jacking up the front or back and
placing it on two stands. Be advised that the manufacturers of jackstands I
looked at, require that they only be used in PAIRS. Steve D's jackplate was
not meant to get one side up on a stand and go to the other side and do the
same. Think about it. I redesigned my original adapter which will bolt to the
stand via a 1/2 inch bolt from the bottom. I had four steel adapters made for
myself and Dale Beuning. They are made of cold rolled steel (finished as
machined) and weigh 2.1lbs each, with Grade 8 mounting hardware. I elected not
to black oxide them. Black oxiding the adapter is $40.00 per batch in the
Hartford, CT area. $40.00 each or $10.00 each if you do four of them, etc.
Keep in mind that if whatever system you use to elevate your vehicle fails,
you may fail with it. Do not rely on one system. ALWAYS provide a BACKUP. This
is not overkill. Without a backup it could be. You just don't get a little
gravity. Being older and wiser, I would never get under a car that was
supported by jackstands alone. One backup idea that I found interesting was
the person (forgot his name, let me know if you are reading this and I will
add it) that used a ~10 inch diameter log cut to the proper length. In the
near future, I plan on duplicating this idea out of a hollow, capped metal
tree :). With the E36 this would also make an excellent fixed length
jackstand. Use any of the above at your own risk.
