Here is the deal...I have a 100lb. punching bag that I am waiting to hang up in my garage.

Two different people at the store that I bought it from told me that it won't be a problem if I hang it from a joist (duh).

But my sister (who I live with), is paranoid about it being too much weight, especially when it is being pounded by these toothpicks that I call arms. Does anyone know if it is a bad idea to be putting it up?

I know some people put them under their decks so I was thinking it was the same concept...but she is still paranoid.

Also, I want to use my garage to park the car as well. So I will be putting up and taking down said punching bag after every use. I have devised a pulley system that looks like it will work.

I plan on having a hook in the joist and run a rope through it. The rope will be knotted at one end and go through the chains (3) of the punching bag underneath the chain's hooks to give it some slack so once they are close to the hook in the ceiling I can just slide them on up there and slowly let go of the rope leaving the bag hanging. Taking it down would be the same process only reversed.

Anyone got a better suggestion? Thanks in advance.

Not a problem from a single joist. But if it will make her feel any better and that's important to you, you can run a doubled up two by four between two joists. This will spread the weight across two joists and may ease her mind. As far as the pulley system, it seems a bit elaborate. If you hang a rope from the joists low enough to reach the top of the bag, you should be able to grab the bag with both arms in a hug, lift it up to take the weight off the hook while supporting the bag with a leg, your chest, or stomach and reach up to unhook it or rehook it. It would also help to build up those arms.

If a joist can hold up the weight of a person on a deck then 100lb. punching bag should not be a problem. I would stick with convincing her and not putting a brace in between two joists because that is a lot of unneccessary work. There are also, metal attachments that wrap around the joist with a hook on the bottom that makes the installation a lot easier.

I would do the metal attachment deal if the ceiling wasn't drywalled. I feel like that will be a lot more than I planned on doing (then again my whole pulley system is a bit too elaborate as onetime2 pointed out).
Anyways, I'm just gonna screw in the hook into the joist through the drywall.
And after reading your responses and quoting some of them, she is fine with it (or so she says).

Thanks.

I had a similar situation where I needed to hang a (light about 100lbs) heavy bag and I still needed access to the area. It was in a shop, not a garage, but same difference.

I did use a pully, but I hung it about 4-5 feet away from where I hung the central point of the heavy bag. I used rope and sling made of an old pair of jeans. When the bag wasn't in use, it was slung up parallel with the ceiling.

I hung my 100lb bag from a joist 6 months ago and I've been punching it like crazy ever since then without any problems.

Id skip the rope and feed chain through the hole.

drill a hole into the joist and loop the chain through

I can guarantee unless you use the worlds longest screw

ie 10 inches or more it will pull out .

The ceiling is covered so I am using a stud detector to find the joist. How would you recommend looping the chain through the hole in the joist? Or am I missing something here?

If you go this route (with the chain going through the drywall on one side, around the joist, and back through the drywall in another spot) you will be eating away bits of drwall whenever the bag swings.

Good call onetime. If it does fall out with going directly in the joint..I'll try and figure something out (in other words...come back here).

onetime2

If you'd like to insure a tight fit and you're not too worried about getting the screw back out of the joist in the future, put some construction adhesive on the threads as you screw it into the joist.

Of course, if you want to get the eye bolt (or whatever you're using) back out, this isn't the way to go. You may have to cut it off flush with the drywall rather than being able to back it out of the joist.

Working great! I just stuck to my original plan and no problems (as of yet).
