Yep, Savage feels a little teetery up on any form of lift, so you rope it down so it can't go anywhere.
Trick on a Harbor Freight lift is to rope it off with an inch of lift still remaining, then finish the last inch of lift
pulling the ropes nice and tight.
I've also learned to take the time to put 2 tie downs per side when doing any heavy torque work like rear tire nut removal. Rear tire removal causes a weight shift on the entire bike, so two tie downs per side is definitely needed !!!
I have changed the rear tire with the wooden pivot jack and with this one, so I can say that getting enough lift to GET THE TIRE OUT FROM UNDER THE FENDER is a good thing (with the wooden pivot I had to remove the liscense plate bracket to get the tire outta there).
Cost is considerably different though -- wooden pivot jack cost like $5 to make, bike jack was $275 to buy.
I considered a rafter lift, but didn't go that way since I leave a bike on the lift for weeks at a time when working on it. Plus with the HF lift you can wheel the bike around and move it sideways, etc as needed.
(just remember to rope the sucker down good with two ties per side before doing so or you'll be picking it up off the floor)
