Project 12i #8
Ok, moving right along! The last few steps took a bit of doing, but seems I may be closer to a test drive. I know the resistor looks a bit off, but I took a chance and twisted the angle of the barrel. (blasphemy you may say...I know I had to look at it for a day or two to get over the different look.) For now I have the mount secured to the radio tray with a single AE 8-32 alum screw.
At this angle the barrel changed little in weight distribution. The wiper arm is stock and flat. The wiper buttom has optimal travel across the resistor surface in the middle of the bands. The resistor sits higher up with the parma mount but not by much, so I made an offset spacer that served two functions. Height change and added strength.
First, the wiper does not have to be tweaked much to get a the right angle and pressure at the button and secondly the servo disc/horn will not suffer from repeated loosening or tigthening of screws into the disc itself. I have though bolted the disc to the spacer, use only 2 holes, to preserve flatness and strength of the disc. On the top side I have 2 more holes for the wiper itself with ample surface area to hold the wiper down. Amazingly, the Novak servo disc with 21 splines...for the nesa-1a/kraft 33N on this car was and is the hardest part to obtain. For anyone using the classic novak servos, the servo horns and discs seem to be elusive. Novakpleasemakesomemore
I have been using a rx battery up to this point to test/tune the radio/servos. I set up the pinion and spur, turned on the radio, and ran the thottle up and down. She's back to life again! Next up, radio plug and diode, body, paint...
