Heavy Bag and a shaking townhouse

[skilzkid]

I asked them about that before I ordered...they said something along the lines of I would be better off without the spring upgrade for bags under 150 lbs since the thicker/stronger spring wouldn't compress enough and absorb less shock with the lighter bags.

I went through a similar exercise about 10 years ago in trying to get a heavy bag mounted in my garage. It shook the house so bad that it made stuff fall off the walls and shelves. Then I got two engineer friends up in the rafters for a weekend helping me reinforce and buttress the 4x10 the bag hung from. We finally concluded that the garage as it was connected to the house couldn't be reinforced without quite a bit (tens of thousands of dollars) of structural work.

Later, a friend of mine in L.A. showed me his garage setup, and I must say that it worked as well as anything I've seen. What he did was to get four steel I-beams and drill 'n fill them down into the foundation about 5 feet. Then he constructed two I-beam cross members that spanned his garage and then connected two other crossing I-beams for reinforcement. On those cross members he placed two a couple of bags that ran on rollers and had a hand-brake you could set when you wanted to kick it. This was cool because you could pop the brake after your workout and still park your car inside.

The downside if any was that you really didn't want to run into one of those vertical I-beams when sparring. They'd ring your bell for sure.

Is there anyway that you could incorporate a heavy duty rubber ring somewhere inbetween like the kind that holds up your car exhaust? (these seem to take a lot of weight & are designed to reduce noise/movement).
