Attaching Props on the ArctiBaby
Here's how I finally put my props on the ArctiBaby. Start out by balancing the props. They're too small for any kind of normal prop balancer, but hanging them on a paper clip worked fine. Plain transparent tape worked well for the balancing.
Then I reamed out the hole just a tiny amount, enough to start the prop on the motor shaft. If I reamed out enough so that the reamer came through the top, it was too much and the blades would slip.
I then put the prop on the motor shaft and centered it. I tried pressing it on by hand, but the props are pretty light and I worried I was giving too much stress on the blades themselves.
I put the bolts on a firm surface and lightly tapped them in with my smallest ball peen hammer. I was worried I was going to bend the thin prop shafts, but it worked well with just a couple of taps.
