Does anyone have the plans/materials specs on how to build the rolling bucket of cement for the tail stand?

I had ran across it in the plans and can’t remember where they are. I think I should be able to get the needed supplies at Lowes.

Also Looking for recommendations on a floor jack for the ES.  It seems that many of the automotive ones are too big or cumbersome to get under the main wheels.  I don’t know about jacking the nose up?  How is that done.  I was told you can lift from under the firewall.  

Lastly, is there an affordable motorized tow bar that works with the nose wheel fairing for the ES.

Thanks all.
