If you're worried about it, you may want to consider using 6圆 in place of 4x4s. After several months, the braces seem to have prevented any further breaks. It was more than a year before the post broke. The final pic also shows the repair of the corner. After one corner snapped at the deck level during a sparring match, the braces were added. The plywood should be staggered by 4ft make sure you spray or roll a coat of water seal on the bottom of the decking before you lay it down.Īs noted in the final corner picture below, when the ring was first built, it did not have braces on the corner posts. Make sure you crown your joists and try to keep the tops of the joists and blocks as even as possible. 2x10 boards are used to scab together the beam and band where they meet on the posts. Between the joists are 2x4 blocks every 4', which stabilize the floor and act as nailers for the plywood. Our 2圆 floor joists are 16' on center and sit on 2x2 ledger which is nailed to the band and beam.

The joists and bands break on these posts. Essentially, we're building a 20x20 deck with 4x4 posts every 10ft. If you're regularly going to be sparring with folks over 220lbs, you may want to consider 5/8' plywood.īelow is the materials list and the basic plans for the ring. Water pooling - partially fixed by drilling holes in plywood and lining the holes with epoxy.ĭelamination of treated plywood - minimized by addressing the water issues and caulking the seams between sheets.īesides these items, the ring is holding up very well getting about 3hrs of work per week by 3-5 people. This ring was built during the summer of 2010 (published summer 2012) so we've had two years of use to work out the kinks.

The deck is not padded, but the 1/2' plywood provides a little give. The finished project is a 20ft deck with 16x16ft inside the ropes. With some prior experience with carpentry, it takes about three days for three people to do.

Don't have $10,000 to spend on a boxing ring? Don't have a warehouse in which to fit one? For about $1,200 you can build one in your backyard.
