Jack Stands and the G
Yes, I still plan to make them, and will post a detailed update of the designs and prices shortly. As most of my car projects seem to these days, this one is taking longer than expected, but we are getting there.
Since this was originally Dave's idea, and my design is very similar to his, I didn't want to step on his toes, and checked with him first. He not only gave me the OK to proceed, but was actually very supportive. Thanks, Gary!

1) Jack stand adapter. These would go over your jack stands, like in Dave's pics. Mine are specifically designed for Harbor Freight stands, but could fit others with similar design.
2) Floor jack adapter -- this is what you're talking about. I was going to make these as well, out of aluminum, but I like these Urethane pads, and mine wouldn't be any cheaper.
When I did a search of what was already available on the market, I could only find ones made out of steel U-bar, which I didn't like. Thanks for the find!

Here is a pic of the larger size lift jack pad that fits on a floor jack:
They want $10.50 for shipping a $22 part. That bothers me.
I was looking for another company that sells these, but have not found any.

Not yet. I have the aluminum design finished, but am also exploring making the adapters out of Urethane. 90A durometer Urethane can be relatively easily machined, and the material cost is comparable.
I plan to post details next week, and pull the trigger in early March, once we confirm the quantities with everyone that was interested.

A quick update. After looking at machining these pads, first out of aluminum, then out of urethane, I finally settled on molding them out of urethane (about 90A Durometer). This is really the best way to do it, and hopefully the larger upfront investment will pay off.
Attached is a CAD model showing how the pad sits on the Harbor Freight jack stand. The semi-circular side skirts prevent tipping off to the side, and the pad is constrained in the other direction by the jack stand, and the conformal fit.
The master should be made on Tuesday, with the mold to be completed by the end of the week. We'll then cast the first set. If everything goes OK, I'll post pics of the finished pads next week, along with the final pricing.
