I posted this question over at Knots, but thought I’d give it a shot here too ! I just finished a nice shade structure over an outdoor dojo for a Tai Chi master. Now he wants me to build a wing chun dummy, for martial arts practice. These can be fixed in place, or they can rotate, which is what my client wants. I’m wondering what type of (LazySusan?) hardware I could use for the bottom ? This will probably be mounted to a concrete footing. You know, a lazy susan type arrangement might be a little to free-spinning. This dummy should have a little resistance I’d think. Anybody have any other ideas for the attachment ? I was thinking about just using a big dowell set in to a socket, but, this will be outdoor, and a socket would collect water. |

How freely does it need to turn and how fast should it stop? If it's going to be a permanent installation, you could go to a shop that sells trailer parts and get a spindle for a trailer axle with the stationary end pointing down and the flange for mounting the wheel (in normal use) can be bolted to the bottom of the post. That way, you could have them cut the hub off of a wheel, the bearings would let it rotate and the hub would keep the wood from breaking, especially if they welded a pipe for the post to set into. If you want to slow the rotation or make it stop faster, you can tighten the nut on the hub.
I researched this once back in the day, and found that it was cheaper and easier to buy it. You might want to go have a look at one though and see what it is that they actualy use for hardware. It would be better then guessing and give you an idea of the movement you want to allow.

Talk to the Master, he will probable think free spinning is good.
Like HighFive, I think of a trailor axle. But mounted to the tire. The tubed tire filled with water. Warp the tire in canvas to prevent scuff marks and for appearance.

Well, that trailor axel setup sounds pretty good, but boy, all the time and trouble. I'm hoping for something off the shelf.I know it would be cheaper to just buy it, but this would be fun to build !
Joe,

Why else are you in the business, but to have fun on someone elses dime?

Looking at the example pics, I would expect lazy susan hardware to last 5 minutes, as long as he was gentle in that time.....

We've got one of those in our dojo, I could build one too but I wouldn't.
Go buy it, you'd be father ahead.
As Bob W. said, lazy suzan hardware will last about 5 min. with the beginners. The hub idea is good but still............. hell I'd buy it. Anything less than solid as a sh!t brickhouse and all you have is a ugly tree standing in a corner.
