I've got a wooden one but I'm not happy with it any more. I built it with measurements off my favourite dummy at the time, but we got some new dummies and I prefer a higher one these days. We also got some arms on springs on one dummy and I really like that.
Now I want to replace the wooden one with a steel one. I've got some ideas and materials together. I want to have removable steel spring arms and leg and the body mounted on rollers with old moped shock absorbers and bearings on tracks controlling the horizontal movement. I want to have dense foam covers on the arms and maybe the leg so I can hit them hard enough (I find bare steel too harsh). Also padding on the body and head because some of the strikes in my dummy form hurt without padding. The springs I've got in mind are very stiff. It was hard to find springs burly enough but I went to an industrial spring supplier and the heaviest ones they've got should do. They seem to work well in prototype arms I rig up. I don't think the project will be easy, but if I can create the dummy I've got in my mind I'll be pretty happy.
