I saw somewhere - and I’m sure it was Insta - a shop that had created a counterweighted workstand, such that lifting and lowering a bike was easily managed by the weight on the other side.
I seem to recall it was a frame made from what I would guess was extruded aluminium, with a chain moving the weight, and I think (well, hope) that it could be locked in place.
I’m curious as it’s the kind of thing I’d like to replicate - that is if the cost, time & effort of making one doesn’t get negated by being too close to just picking up a Park PRS-30 (or to stump up a bit extra for a Remco).
I’m also contemplating a ceiling-mounted stand solution and this approach would be better suited to that.
