Right now, Harbor Freight is running a special on a "Bare 18 Volt Cordless 3/8" Right Angle Drill".
The reviews looked good (except for the guy that didn't know "Bare" meant that it lacked battery and charger), so I ran out to Glen Burnie to get two. The shelf still says $30, but they each rang up at $17. * http://www.harborfreight.com/power-tools/cordless-drills/18-volt-3-8-eighth-inch-cordless-right-angle-drill-67043.html *<http://www.harborfreight.com/power-tools/cordless-drills/18-volt-3-8-eighth-inch-cordless-right-angle-drill-67043.html> I think they may be too small to drive a Sherman, "But, If I duplicated the Stuart with 1/4 plywood ..." Then I gave my plastic Stuart a good look-over, and noticed that the Stuart's plastic tracks have a single center-guide tooth instead of two outside teeth. The next thing I remember, I was designing jigs to produce Stuart tracks out of aluminum bars ... which led to thoughts of reproducing the Stuart's somewhat-functional VVSS from aluminum stock... The next epiphany/pipedream concerned elevation controls: I don't know much about using switches or controls to establish upper and lower limits, so I imagined a doughnut. I propose that a 2" dia wheel cut from 1/2-3/4 plywood, drilled with a 1" centerhole at a .25cm offset (.25cm is 10% of 2.54cm) should raise and lower the gun +/- 10 degrees. If the motor spins the wheel beyond the gun's limits it just keeps oscillating back through it's range. A friction drive against the outside would spin the wheel, and the verticle slit in the front of the turret should keep the barrel from wobbling side to side. The motor could be controlled by a momentary pushbutton, or set it to reverse every time it is pushed (like a garage door). Then I could use the original Stuart's controller, and save the better TX/RXer for the Sherman. I know, I know... build ONE before dreaming about running THREE. But my build is still limited until we go to settlement on the new workshop, uh, I mean "house". But, other than that, what are your thoughts?
