hang a punching bag?
 

i live in a single family attached home, its a condo. i was hoping to put up a 100 lb punching bag in the garage, but i cant seem to find a stud. ive drilled numerous holes trying to find one, and i think i finally did.

does anyone know how far apart the studs are from each other??
it seemed like the stud was about 5-6 inches from the drywall, is that right?

any help is much appreciated.

If you're hanging this from the ceiling of your garage, you're most likely referring to trusses vs. studs. Trusses form your roof, and the bases of the trusses form your ceiling. They're usually spaced 24" on center, with the first truss (gable end) flush with the outside wall. (Meaning you're losing 1 1/2" or 2" if pulling tape off a sheetrocked wall)

there is a unit that lies about my garage. there are three garages next to each other, i am in the middle. two of which are single car garages, and one being two car garage.

This has nothing to do with the truss, but use an industrial strength type hook/hanging device for your bag. We had a 60 lber which we put up, then the clasp broke. We got a much stronger one. A few months later, that one broke. Moral of the story: get a really freakin' strong hanging device. Hopefully one that will minimize friction (our bag was covered in steel shavings).

I just used a thick hook I picked up from Home Depot....screwed that into the truss (stud or whatever its called) in the ceiling, and hooked the back up to that. No problems, and its been a year.

Your trusses are probably 2 x 4, so I guess what I'm getting at is I'm not sure how well a single 2 x4 is going to support your 100lb punching bag, especially since you'd need a big ass lag-type hook to hang it properly. What I'm thinking is some doubled up 2x6 or 2x8 ran across two trusses. This would handle the weight much more appropriately.

i actually intended on screwing a piece of 6x8x2 to two of the studs, and then screwing the swivel hook i got that piece. i was hoping this would help distribute teh wieght. my problem is i cant seem to find those studs. i was also told that those electronic stud finders arent accurate. any of you guys use these? or know of a way to find studs??

most joists are going to be 16" on center from the wall some can be 24" depending on the building
the best way is tap on the ceiling with a hammer or just cut some of the drywall out and patch it later
that woud be the best so you cnb reinforse it to keep it from pulling out or breaking the joist good luck

Make sure you figure out how strong your mount needs to be...then double it. A heavy bag will tear up a wall/ceiling if you're not careful.

Just use one of the electronic stud finders. They are pretty accurate now. All they do is scan for a change in density. Tap the wal or ceiling until you find a spot you know does not have a stud (it'll sound hollow). Start here. Turn on the device and move it until it lights up. This will be one edge of the stud, mark it. Keep moving until the light goes out, this will be the other edge of the stud, mark it too. Verify by coming from the other side. Now drill somehwer between the to marks and you have hit the wood.
