I'd thought of doing some neat things with actuators, but like I said, my focus is on (in order):
1. Comfort (I spend hours in front of this damn machine)
2. Asthetics (its has to stand out and say, "I'm beautiful!")
3. Integrity (it has to be dis-/re-assembled without getting weak)
4. Portability (it has to be light, modular)
With all that in mind, I'm shying away from motors and actuators. Once I'm in a house that I own, I may replace some of the modules with actuated or motorized versions.
Of course, I am thinking of doing some small-scale actuator work in the seat itself. I was actually thinking of scouring a few junkyards for an abandoned power bucket seat from a european car. The biggest issue there is, again, weight. But if I make it fully detatchable, it shouldn't be too much of a problem.
BTW, RobbieRob, I'm down here in Columbia, SC, at least for a little while longer. Though I may not yet be your man. Remember, I have only a few months experience. I'm picking it up pretty fast, and think I have a talent for it, but I'm not sure how much I'd let someone else trust my solo work at this point. I'll be calling in a lot of favors and getting a lot of help on my little project; and ultimately, I'll be the only one who has to live with the consequences should I make a mistake.
As for the cost, I've set aside about $700, which should cover the cost of the lumber and the plastic and fiberglass trimmings and coverings, paint, polyurehtane, and other assorted materials. Fortunately, between myself and my co-workers, there's not a tool we don't have (or have access to) amongst us.
