By dint of severe effort as much as possible
We sometimes work our way up step ladders, one end, one rung at a time.
Sometimes we build a gin pole and use come alongs or block and tackle, Ive lifted a 8x16"x27' oak log 2 storeys that way before.
We've used pump jacks and slung timbers under them.
After that its time to spend money.
The old timers also used 2 skid poles up the wall and a cross haul.
We can rent a hand operated genie lift, basically a hand operated forklift using a boat winch.
With any of those methods, keep your wits about you. You're just a bug to that timber.
As I was laying in recovery from the second hernia operation Dad asked how it felt to be outsmarted by an inanimate object, again
. The doc allowed that just cause you can get your arms around it doesn't mean you can lift it. Outsmart em, you'll last longer
