Heavy Bag and a shaking townhouse

[skilzkid]

I got my 6 ft banana bag mounted in the garage...my fiancee says that it shakes the house just a little bit when I hit it. I was wondering if there was anything extra I could do to absorb some of the shock...my set up is as follows:

Bag from

straps are sewn onto the top of the bag, weighs about 100-110 lbs

S-hook

Mount from

Sorry, I have not checked the links yet, but the thread title brings back some hilarious memories!!!

I used to train at Master K's townhouse in Springfield, VA. We trained in his basement, and he had a heavy bag hung from one of the support girders that ran across the entire set of units. Master K's townhouse was in the dead center.

The neighbors called the police on us one day because we were kicking and shaking the entire row of townhouses. Apparantly things were falling off of peoples walls and shelves. I had happed to go outside to see what the commotion was as one of the other students continued to kick, and you could hear each kick as it reverberated though the entire complex!

LOL

Master K ended up getting a custom built "Cornerman" type heavy bag hanger.

Shoulda, woulda, coulda...

Hey Skilz, you should try that cord method of hanging the bag I suggested to you a number of months back I don't remember what the post title was now). Takes care of that problem. Chalambok got to kick it many times and liked the set up. I've used with my 6ft bag for a few years now. You could still use it with that hanger system you have. Worth a try.

Thanks for the reminder on that...i think the one prob I may run into is space...right now, the bag is a little less than a foot off of the ground, and this includes the mount, an s-hook, and the 6 ft bag only. The bag has sewn-on straps on the top with two attachment rings (I'll try to remember to get a pic of it sometime tonight). So, if i get a thick foot-long bungee, it may take some more of the impact, and I could loop it through the mount, which would drop the bag 6 inches, but I would gain 2 inches by removing the s-hook...

Found it. I'll just copy over the parts that are relevent to you now.

Six: flat heavy duty black rubber bungy (sp?) cords with metal hooks (the 19" Quick Straps with heavy duty hooks by M&K Industries. Get them at Home Depot).

The quick straps are 19" long, but you double them up so they end up only being about 9" long.


...Because I was
going out in the garage at 4:00 am to do my solo training, I had to come up
with a way to hang it that wouldn't cause a lot of jarring like a chain will
(I didn't want to wake up the kids, or even worse...THE WIFE). What I ended
up doing was getting six flat heavy duty rubber bungy (sp?) cords with
metal hooks to hang the bag with...

...Start with two bungies, put one hook of
each cord into the eye bolt, run them through the strap and back up to
the eye bolt. Do the same with the other two straps. This way you have two
bungies doubled up and supporting each strap. The bag ends up hanging about
3 - 4 inches off the floor
It works great. It held up great for over two years and I only had to replace two bungy chords. It's quieter and less stressful on the rafters. Also, it's
easier on the joints of your legs.

BTW, I like my bag to hang about 3-4 inches off the ground.

Just so you know what I'm dealing with...I may not have the room for the bungee cords, but might put up some 2x4s across the ceiling, then put the mounts in the 2x4s, so I can spread the weight across multiple beams.

[skilzkid]

Another one a little closer...

One last pic...as you can see, there is next to nothing extra on the top, and the bag is still less than a foot off the floor...I may not have the room to add bungees.

Thanks for all the feedback.

Iv'e done what you said with the 2 x 4 in the past & i got a little improvment but i found if i put the bag closer to the wall the room didnt shake so much & the bag didn't swing as much either.
Is the bag weight - light , medium , or heavy? as this can effect as well.

[skilzkid]

It's a six foot bag, UPS ship weight was 105 lbs (about 48 kg). William's other posts were saying to use 4x8s across the ceiling, which almost seem too thick to work with. Also, given the above pictures, would the bungee idea have any effect. The mount seems to do a pretty good job in absorbing a lot of the shock, but at this point I'd still end up waking the girl and the dogs...

I went with the 4x8 because I wanted a thick, solid place to anchor the eye bolt that the bag hung from. 4x8 mounted across the rafters, bag mounted to the 4x8. I felt that a 2x4 wouldn't be thick enough to mount too and hold up to my abuse.

The Bungees will absorb the shock. Besides they only cost a few dollars so you won't break the bank in trying it out.

As you can tell, instead of mounting a single eye bolt, I'd end up mounting that shock-absorbing mount that I bought. The bolts for that were about 2 or 2.5 inches. With the thickness of the mount, those bolts would probably barely go through the 2x4 into the ceiling. Given that there are generally 16 inches between studs (on walls at least, I'll have to measure for ceilings), I'll end up getting 2 4 foot 2x4s, and either 3 or 4 inch bolts to mount them into the ceiling (I still am considering 1 4 foot 4x8 with 5 or 6 inch bolts...I think I'd have to get a new drill bit set to handle that thickness)

As for the bungees, I'll have to see if they have them short enough to work with.

Thanks a lot for all the feedback...just trying to really talk this out before I put 1000 holes into my ceiling experimenting

Balasz also has a "heavy-duty" spring for the H2S mount. You could see if you could substitute the stronger spring inside the mount. Ask them if it'll absorb more shock.
