I picked up a 12v scissor jack from lowes for $75.
It's rated at 2000 lbs, works great.
Question: What does one corner (wheel) weigh?
I'll WAG 900lbs? (.25 x 3600)
Look for a silver sticker with black lettering and a QR code around the edge of your driver's door (the edge on the Bolt's body, not the edge on the door itself). That sticker lists the GVWR which I forget but I think it means a fully loaded vehicle with passengers and some cargo using some averages for passengers and cargo.
Mine shows a GVWR of 4458 lbs, with the front being 2237 lbs and the rear being 2221 lbs (~51/49 split) so fairly symmetric distribution. I guess you could WAG it at about 1/4 of the GVWR, or 1100 lbs / corner *ASSUMING ALL TIRES TOUCH THE GROUND*.
It's been a while since mechanical physics, but depending on how rigid the Bolt is, wouldn't lifting one corner of the Bolt eventually lift the other nearby corners? So you could be lifting 1100+ lbs as you raise a corner higher and other adjacent corners start lifting up. When lifting at the lifting pads with my floor jack, I did notice the entire side of the Bolt started lifting once I got past a certain height.
On that note, has anyone actually used the pinchweld for lifting or placing your jack stands? I have seen
this diagram, but I got nervous hearing horror stories about heavier vehicles (3500+ lbs) crunching/pending at the flange when lifting. I ask because
@ldesaul bought a saddle-type lift for weld flanges.
