Ok im gathering materials to make a hitch hoist. just gonna use a bit of 2" square tubing and a come-along. how would you guys make a swivel that could be exposed to the elements and still work efficiently? i want maximum payload from it, if i decide to pick a motor, i want to be able to yank it no problems. im not buying it either, just materials will be purchased.

i thought long and hard about using an old bearing from my 8.8 carrier, but i would have to seal it. maybe a brass bushing / wear ring?

 

bronze bushing is the way to go brass is too soft imo

 

hrm. wonder if i can locate any bronze stock at work, i think its all brass.

 

ok so all i have is brass, probably touch soft for some things.

guess i need to look into a thrust bearing idea.

 

yeah i mean brass will work but it wont last very long if you were closer i could hook you up with some bronze

 

i'll post pics when im closer to done... had an idea i just couldnt pass up, involved cutting something up and using the ironic part of it as a paper weight... yielded a pivot point with a bearing.

 

my new paper weight


the hoist.

Just a thought here but how about a driveway gate/barrel hinges? I think I paid about $40 for a set when I built our driveway gate a few years ago? Not the cheapo hinges from the big hardware stores but the ones that actually have a bearing inside and grease fitting on the end. Something like this. http://www.ironmountainhinges.com/se...ges/Categories

 

thats a damn good idea! 600# gate rating, thats probably a 8 foot span, so thats probably well over 800# comparable load for the extra weight hanging off the side.

 

They make different sizes to handle different weights so there is probably some that will handle even more if you need it. Good luck with the project!

 

ah i see the problem with those... designed to use two on one hinged item.

 

I guess you could use just one but it would probably cut the capacity in half? Not sure exactly what you got planned but they aren't that big and can be fit pretty close together if needed? Oh well back to the drawing board!

 

Maybe its just the pictures, but it looks sketchy.

 

Holy globby welds batman!

You should cut that apart, grind those down and adjust you wire speed and temp and lay a nice pretty strong bead on there. If your going to be lifting with this thing you will want it structurally sound, and personally I wouldn't trust that weld with a motor hanging from that arm. Plus I like my welds to look nice and neat.

Also why did you change from the heavy square tubing to the light weight tubing you have at the top? I wouldn't trust that tubing with much weight on it at those lengths.

 

free scraps lol.
2" is all i had so i made that be the base, the 1.5" tubing, yes its 1.5" lmao was scrap pieces from other projects. i honestly plan on either doing it all 2" when i run across more cheap/free scrap, or just making another upright for a harbor freight hoist deal that looks perfect. http://www.harborfreight.com/cpi/cta...temnumber=1647

i had a hard time getting penetration on the pinion, i never did consider its a hardened steel (at least the surface)
