extra heavy duty jack stand

Nice work Frank. You should slot those holes a bit, then put a second set of slotted holes 90 degrees out. That'll let you put a second pin in, perpendicular to the first. Lift it half an inch with the slotted hole but keep it pinned, then put the second perpendicular pin in. So there's always one pin holding it and it can never drop very far. Keeps the blood blisters off your thumbs.
