Ok, maybe the solution is to mount it from some joists instead of on the I-beam. I guess you get a metallic sounding vibration noise that carry’s through the house?No way of mounting in the garage. And it does not shake the house, it is just the noise vibrating through the steel I-Beam it is mounted on. I admit, because of Xuefu, I am mighty, but not even I, with my extreme Xuefu power, could break that I-beam

Are the joists in the basement exposed? Take a piece of 3/4 plywood to span the distance between two joists and mount it with two or three screws on each joist. Make the piece maybe two feet long on one side, and the span distance between the joists on the other. Drill a hole in the middle of the plywood and mount a heavy eyescrew in the hole, using a big fat washer on the top side. Use a heavy clip to mount the bag to the eyescrew. I think the wood joists will dampen the noise, it won’t carry through the house like the I-beam does. That’s how I did it when I was a teenager in my parents’ house. The clip and the eyescrew tend to creak a bit, but maybe it’s an improvement.
Yeah, attach that device to the plywood instead of an eyescrew.My previous house I had something similar mounted to the main support beams. For some reason in that hose they but four 2x8s together as the main beam and I attached something like this to it, but it was a much older version. I shall look at the basement to see what I can do, thanks
I don't think the plywood is strong enough. I use a 2X12 to span across 6 of the 2 X 12 joists on the ceiling(the floor joists of the second floor). then I mount the heavy bag on the 2X12. Still it really shaking the floor of the upstair. I thought if I spread the weight across 6 joists, it should be better, NO!!! I only use a 70lbs at the time.Ok, maybe the solution is to mount it from some joists instead of on the I-beam. I guess you get a metallic sounding vibration noise that carry’s through the house?

I mounted one as I described, 70 pound bag, and it worked well. The house did shake, but I think that is inevitable to some degree. It never damaged anything.I don't think the plywood is strong enough.

One problem is when you punch and kick, the bag actually jumps, like it rise up a little, and then drop down and thereby pull the whole ceiling down a little like as if you jump on the second floor. Only thing I can think of is if you get the kind of heavy bag that actually long enough to droop on the floor, those bag won't jump. But I don't know how those feel when punching and kicking. Never try those, I just saw in some of the boxing gym.
Ha ha, buy a house that don't have living space on top of the garage!!! Problem solved!!! )
Seriously, It's hard. Just try to hang in the area where you don't have fragile stuffs on the second floor. Or you will have to actually build a separate support beam to support the heavy bag so you don't directly pulling the ceiling. I actually put a support beam for my two heavy bag even though I don't have living space over the garage in this house. It's so good that you don't feel anything in the house, even the noise is not bad. I'll take a picture tomorrow.
Ancient engineering school knowledge suggests that you might be able to dampen the vibes with rubber jammed between the beam and the crossbeams. Or maybe you should hang the bag on a spring, and let the spring absorb the vibes?Already did that with an old innertube
Thought about the spring, but it already hangs a bit to low, trying to figure out a way to raise it that doesn’t involve cutting chainAncient engineering school knowledge suggests that you might be able to dampen the vibes with rubber jammed between the beam and the crossbeams.

You can spread the plywood farther than two joists, but I don’t know if it makes a real difference since the swivel mount will be at one spot between two. If you mount the wood to four joists, would that help? I dunno. And actually, maybe go with a full inch plywood.I’m thinking 3/4 inch plywood, with a 2x4 brace, if I go this route
You don't think a multi-spring mount, spanning a couple of beams, with a couple inches of rubber isolation might work better?Its hooked to a steel I-Beam with one of these covered with an inner tube

I don't think the bracket is the issue, the question is how do you hang your I-beam. If you fix it on the ceiling, it might not be that effective. I think the same concept like what I do, if you fix your I-beam on the side wall, that might be a lot more effective.basically this is how mine is hooked up now, just a different bracket
Which makes me wonder if a newer bracket would be better..... this is the bracket I currently have
I didn’t fit it, it is part of the construction of the house, in the foundation, as are 2 othersI don't think the bracket is the issue, the question is how do you hang your I-beam.

I've seen some spring heavy bag mounts that are supposed to help with the vibration.Rubber isolater, like in the suspension of your car?
