I mulled around for awhile over what to build for a new stand and I had all sorts of exotic ideas using bottle jacks and maybe trailer tongue jacks and such, but in the end it came down to something simple without having to spend to much on materials.
I had a half a dozen or so stands I collected over the years and the heavy duty 6 inch wheels, so in the end it was the cheapest way to go.
The two support tubes are just ties and are not a structural part, they are plenty strong enough as long as any weight is distributed on the four corner stands.
The other thing is it probably could be made adjustable length wise by making the two tubes into slip tubes, the other thing is to make sure the legs of the cherry picker will have enough clearence to slide under the stand.
I used cheap chain to secure the jack stands and drilled the mounting holes so the bolt would go in at a slight angle. That way the chain tighten up as I tightened the bolt.
So far it as worked well, is cheap and I am happy with it.
By the way Ron, if you grow a white beard, look a bit pathetic, sometimes you can get a break on car parts, especially if it is a younger woman selling them, it is like they feel sorry for as you remind them of their dad or something.
