KXPD1

[Jeremiah McCarthy]

I have built about 10 KX1's and the retaining screw for the paddle DOES protrude through the anchor nut and in some cases strikes the circuit board, preventing the paddle from being pulled up tight...Not everyone who buys a KX1 also buys the paddle, so it might not be encountered a lot, but I have had 2 of them so far where this was a problem...

There are 3 ways to fix it...(1) file the notch in the circuit board deeper, but this is hairy because it is very close to a circuit trace, (2) make up a thin plastic shim and place it between the paddle body and the KX1 case, or, (3) grind off the end of the knurled screw about 1/32"...IMHO, number 3 is the best option, but it must be done carefully because it will burr the end of the threads making it difficult to start the screw into the anchor nut...To overcome that, CAREFULLY grind or file a 45 degree bevel all the way around on the end of the screw, as if you were going to bring it to a point, but stopping far short of that...It will start threading into the anchor nut easily now...

too much..<

>Should I have screwed the knerled nut on the key jack? The jack on my kx-1
is flush with the upper conver so the nut wont screw on.
Suggestions to solve the case of the wiggling KXBD1<

Also....if you have a nut that you can thread onto the
screw before filing, when you back it off after the filing
is done it will help restore the threads on the screw.
