It's interesting that this discussion of the Link Trainer has been going, as yesterday I had a call from someone wanting me to rebuild his trainer's "bellows", which are actually two wind motors, somewhat "front to front", geared to a center shaft. These are the pictures Gary Guilliat sent me, and I thought y'all would like to take a look. They appear to be built very robustly, and I will be going to look at them within the next two weeks. I'll let you know what I find. Oh, the trainer apparently uses at least three of these units.
