Before starting on the arms I wanted to address something I was not thrilled about. The screw that sticks up from the Susan for the arms to attach to. This was going to be permanently in place. Thing is I could see it getting damaged in shipping or storage. Also things like hanks of precious silk yarn could get snagged on it by accident.
Here’s a mock arm (I will call it mini-arm, BTW, I HATED that movie so much I turned it off after 5 mins and the 50th Ya Baby) screwed down with the thumb screw. It works. But again I’m not thrilled about the screw sticking up after the swift comes apart for storage. Time to come up with something better!
Enter the all mighty “Blind Nut”. AKA “T-Nut”. These are used profusely in model airplanes for things like engine mounts and hatches. I did a Wikipedia search on “Blind Nut” but nothing came up. So bare down for a play by play on how a blind is installed and used.
BTW there is no entries for “Yawn Swift” on Wikipedia yet. Get working on that Shells!
1st thing I need to do is make the center hole in the top circle slightly larger to accommodate the blind nut.
Now the blind nut is inserted from the bottom and the “barbs” hold it in place temporarily.
Then a screw is put in from the top. This pulls the barbs of the blind nut into the wood as it tightens.
Now the blind nut is secured permanently in place. Note how the barbs sunk into the wood.
This allows for an improvised thumbscrew (a screw and wing nut joined together) to be screwed in while the nut stays put.
I guess the term blind nut comes from the fact that you don’t have to mess around with a standard nut on the other side of the wood. Perfect in this case since the bottom will be “sealed off” with the anti-skid material. And it will allow Shells to assemble the swift with nothing more than her fingers… ( *aside from Shells: …which is good, since I am the type that can assemble a vacuum cleaner backwards!* )
Here’s Mini-Arm all snugged down. Time to start the real arms!!!!!
