"anyone is welcome to practice with my stuff."
I'll second the motion.
I see this as more of a "hands-on" event than a teacher-class event - though I do see it to be fairly structured with one item being used (winch / jack / etc) and everyone not directly involved, to be watching. I see several "teachers" involved - but yet not a free-for-all event. Safety in learning is at the fore.
Let's see if we can firm up some list of topics:
Winching:
Safety concerns (catastrophic line breakage, vehicle undesired movement, melted battery terminals [internet fiction?], synthetic vs steel line, soft shackles vs steel D-rings), hooks vs. captive
Straight-line winching
Angled winching (snatch block off of an anchor / tree savers)
Force multiplication winching (something I have yet to do)
Maximum line length pull (how much can be spooled out and winch force vs. "layers of line")
Synthetic line abrasion concerns - abrasion sleeve
Re-spooling (how-to)
Steel line lubrication
Steel line kinks / barbs
Line length multiplication (adding straps w/o them becoming forced together so they can be readily separated / not using heavy metal when connecting items - should a catastrophic break happen)
Lifting / Jacking / Hi-Lift / Farm Jack:
Safety concerns
Lubrication for ease of function
Ratchet strap to hold the jack into the bumper
Chain or strap to attach an axle to a frame before lifting (flat tire issue) so that the hi-lift does not need full length jacking
Using a hi-lift to move a vehicle sideways (stuck in snow/mud)
Does anyone have any hi-lift accessories to use (wheel lift accessory, etc)?
What should be added?
I'd like the group to be filled with those who have never done "
X" before - this would be a good opportunity to get first hand experience.
