Thread: Mounting 100lb Thai bag in basement - advice please.

Floor stand is not something Im interested in.
Im very happy with ceiling mount with the bungee's now, just curious on how many to use

From what I can tell, each bungee supports 50lbs, so with 4 I have 200lbs of support, and of course with 8, 400lbs of support...

Hardball is right. Hanging a heavy bag from your basement ceiling may eventually shake your entire house up and potentially cause structural instability . . . not worth it in my opinion. I'm no engineer, but your bungee cord solution may be an acceptable fix for the vibration problem , but it still does not eliminate the sheer weight pulling on your ceiling joists.

Two other choices--as previously mentined, (1) a bag stand or (2) a Century freestanding bag. The new century bag has a lower profile base so you can kick low. You can use the ceiling hook you now have for an uppercut bag, double-ended bag or something lighter that won't ruin your house. Further, if you have a ton of bungee cords to remove every time you want to switch to a different kind of training bag, it will be time-consuming. Good luck!

I just dont see how I would do any damage to the house the way I have it set up and how things have been specifically strengthened. I wont go into the specifics of how the structure has been isolated and strengthened but Im more than confident that its just fine.

I even went as far as to set up laser gauges on the ceiling to test flex during strikes / kicks as I do not want to crack drywall, and there is NOTHING. Everything has been glued and screwed. Im satisfied that there is no trouble. My concern was noise transmission with the chains, which the bungee's have solved.

Im going to go as far as to set up a scale system to measure the amount of force generated during a bag strike / kick, but with what I can see thus far, its definitely less than 300lbs of force.

I will thank you guys for the advice, but Im not here to debate hanging a heavy bag in a basement... Ive already done all that research, Im just here to discuss noise transmission... which the bungee's solved brilliantly!

dont use bungie cords,use chains,and think the bungie corde will be going up and down and will eventually break,chains wont......use chains.lol

There are 8 bungee's right now on the bag.. its more than plenty to hold the bag and it does a WONDEROUS job of dampening any sort of vibration. Keep in mind the chains are there, the bungee's have a maximum stretch length, the chains will be tight before it even gets close to the max stretch length of the bungee's.

I got the idea of the bungee's from another member on this board:

50 lb punching bag

I find them even more effective for isolating any jolting vibrations / noise than a spring does.

Your kicks will vibrate through the wood which will conduct vibrations easily. his will actually weaken that beam and cause stress on the other beams as that one sags. When more beams start sagging then the whole house will start and then at least one wall of your house on the outside will begin to crack visiably and possibly sag as well.

BTW you can go to home depot and get rubber heat shrink sleeves to put on the chains so they won't rattle. Or just use rubber hose.

Thats one benefit of the bungee's.. they absorb almost all if not all vibrations... Ive got no concerns at all with that. deflection is measured @ 0 right beside the mount even during the hardest kick. Again this is not a debate regarding structural integrity... The whole support structure is isolated in such a way that again, there is no concern @ all.

Sounds like you have an engineers mind. Your house should be o.k.

An engineers mind, thanks, you are perceptive
