I've measured a bunch of clips and washers to come to the following conclusion
the original washers are .020" thick, the washers I'm supplying are 0.015 to 0.020" thick. i believe the .005" (max) difference to be negligible. I am going to test how much weight it takes to pull the bell tight against the spring clip with the hypothesis that the props make that much thrust or more at idle thus negating the gap in flight.
the original spring clips are .015" thick and the spring clips I'm providing with my bearing tool are identical in design and thickness.
i've actually had trouble with the original washers where they were a tad too thick and made installing the spring clip difficult. in fact, i suspect it was an improperly installed spring clip (back when I used to reuse the washers) that allowed a bell to fly off of one of my helicopters causing a minor crash.
more on this to come. thanks for the early orders, I appreciate it.
I forgot to mention in the ads that the aluminum tool parts will be anodized yellow. :triumphant:
