If you want try something, go to a construction site and pick a large diameter (8-10 inches) PVC pipe, carve out some holes for arms, pad it, and mount it. If you need it, I can give you some ideas on connecting the arms and mounting it (you do want it to have a little movement).
Yes, I definitely want to hear your suggestions on mounting the arms/leg (for some movement) as well as padding/covering everything. Also, what do you suggest for some movement of the entire dummy itself? My preference is for some resistance, so that the torso/arms/leg do not move too easily, i.e. that it would "push back." Is this possible with a free-standing dummy? I'd like to be able to manuever freely around the dummy, which is something not possible with a wall mount or certain floor mounts.
Another idea that I enjoy uses a double-end bag. Fix a string onto a tennis ball and hung it from the same point as the double-end bag. The string should be just long enough to let the tennis ball rest on the middle of the double-end bag. As you hit the double-end bag, the tennis ball bounces and flies around randomly. Focus on keeping your timing on the double-end bag (remember to move your feet) while slipping and/or blocking the tennis ball.
Great suggestion! I think I'll try it!
I would also suggest, going to a tire store and getting some old tires (they give them away). Bolt them together and shove a long stick or two in between the tires as arms. Make sure the tires don't have any of the steel belt showing.
This seems like a good outdoor alternative, if my fiance would be open to it. I know she would absolutely veto the tire-dummy for an indoor space.
All that stuff is interesting, but for my money, I am content with a thai bag (with as small diameter as possible). I also like the BOB (Body Opponent Bag), but unless I had a school, I would not buy it just for myself.
I'm curious... Why the smallest possible diameter thai bag? I wonder if it's feasible to easily attach arms/leg to a thai bag or a Wavemaster XXL.
I kinda like the BOB, but wish it had arms (for trapping, etc.) and more lower body (for leg attacks and checks). Here's a variation on the BOB that intrigues me: http://www.dynamiccombat.com/images/academy/acadDummy.jpg
