Has anyone seen this? I want to build one.
Clever. I have to wonder why the builder didn't mount the chair closer to the pump handle. That would seem to have made it easy to straddle the handle, and raise or lower the seat while seated. Might also eliminate the need for the extension wheels on the base, or at least permit their length to be reduced.
I'm thinking an inclined weightlifting bench also might be used for the seat instead of a creeper.
I have one of those low-rise transmission jacks, in red. I think I'll go study the possibilities for a while...
