Step 1: Materials
I used a couple of strong magnets from some hard drives as a stud finder, since my ceiling beams are made out of galvanised Zinc or some galvanised iron.
Then tap 2 holes large enogh let throug a 1/2" toggle bolt anchor to the othe side. Distance between holes, in my case about 2 feet apart, since thats the width of the canoe in that point
12 - small pulleys 30-50 pounds
4 - 1/4" x 2" long Closed loop bolts
4 - 1/2" toggle anchor for 1/4" bolts
25 mts of high strenght, little elasticity rope, (1/4" diametre I used)
Lots of Hard drive magnets.
1 - 1/2" drill bit
5 to 6 foots of flat rope, it was from some rack tensing strings.
In material y spent about 15 to 20$ I already had the ropes , only bought the pulleys, hooks and molleys.
Step 2: Anchor
It you have a concrete ceiling in your garage, you can use expandable anchors that can hold a lot of weight.
Step 3: Insert hook and pulleys
I use close hooks, then with a bench, I bended them so it will make 1 spiral loop, just by opening the hook.
