Of the home-workshop items I have made the one use probably the most on a daily basis in the Small Lift-Table on Wheels. It came about as sort of a test item and now I roll it to where ever I am working and raise or lower it to the correct height for the project. Sometimes it is a work-table and other times I sit on it at a good height to weld items.
The photo distorted view makes it look crooked in the photos but it is very level and stable and before I had the Extension Arm Hoist I lifted a 350+ pound item on it and goes well above 5ft and very close to the floor in the lowest position ...
On a different project lowered it all the way down and laid on my back on it and rolled under the metal structure and welded and was able to roll around and weld different areas quickly and comfortably and finish much faster.
