My prybar collection includes bars 5' to 6' long, several styles, including a few bent ones.... I can use them outside the shop to get a machine on blocks high enough to get the toejack under them, but once inside there is just not enough room. The crowbars are used occasionally, they seem to work best for demolition jobs.
man, my shop is jammed, but I can still swing a bar here and there, but hey, far be it for me to contradict another guys "need" for any tool or equipment,
having said that, I have used a 2 1/2 T floor jack to raise up the Graziano SAG 17 to get wheels under it once it's against the wall, but at 3950 it's a lightweight for it's swing, being "raised in the sand". toe jacks would have been a PIA to use for that, would have needed at least two, and I'd have had to clear space to get them on the backside of the headstock.
bottom line, jockeying heavy(ish) shit around is an art, and what we end up juryrigging and such is endless.
I think its a "ton" (sorry..) of fun myself.
bottom line, whatever works AND is safe, go for it!
