    Solution found! One brass strip at the corner hobby shop $1.49, three holes one screw two washers and a nut out of the garage add one existing weight and a swingarm is made!

    Silly suggestion I know, but have you tried Vibroplex itsownself? I got my larger weight for my Champion right there.

    Donnie used to make square weights. I have one on my Lightning bug.

    I use a wooden clothes line clip that has a metal spring that I can clip on to the weight screw for low speeds or down the pendulum for medium speed, and for real slow sending, I clamped the clip in a vice and drilled a slot into the inside of the wide end to accomodate a long wood screw that extends it even more.

    I prefer adding length rather than weight to the pendulum. I believe too much extra wight would eventually wear out or deform the bearings. Lengthening a pendulum will increase the time period of the swing.

    Me too. The clothes pin is also what I use.

    I find that adding length also forms the dits better.

    It's a shame to slow down the Champ, it really sounds good at 20 WPM+, but so many of the people on CW are new and I want to slow down to keep them going too.

    Also found a bug zapper on Ebay. Love it!
