Re: [cw_bugs] too much weight?
- Hello Kate,
It depends on how big the weight is!
Vibroplex used to only have what is NOW called a small weight - they supplied two of them. Vibroplex sells a big weight equal to three small weights. I've loaded a bug with TWO of the big weights - the entire vibrator was covered with weight. I had no problem.
I've seen people who wind solder (lead/tin) around the vibrator, people who tie fishing weights to the vibrator, or unscrew a PL-259 and use the gap between the shell and inside internal edge (usually inside that is - but it is showing when you do this) and screw down on the shell and grip the vibrator.
I've never repaired one that was damaged by anyone doing this - but that doesn't say that if you play rough with your Vibroplex you won't hurt it.
A Vibroplex is like a musical instrument - be gentle with it - but it surely can take a moderate amount of weight - maybe up to an ounce or two - at any rate about six times the small weight if anyone cares to weight the small weight and multiply by six, or the large weight and multiply by two.
I've also seen solid brass rods (1/2 inch stock) filled with lead used as weights.

Is it possible to put too much weight on a bug for its own good? What I'm asking is - can I harm the bearing or whatever, by adding another weight on the outer end of the pendulum? The nonstandard weight was machined by a friend of mine for his bug, to fit right over the end of the bar. The bug is a Vibroplex Original from the 1970's, which I found at a swap meet.
Hopefully this is only a short term issue, until I can do code faster. I'm guessing that the loaded bug sounds good at about 10 - 15 WPM now, so far used by me only in practice because of the "extra dots" that I occasionally still get.
- As a practical matter, none of us is likely to "wear out" a bug by using too much weight. Having said that, it is intuitive that the more weight you add to the pendulum, the more wear you will have on the trunion pin and its socket. The downward force of the added weight (or any weight, including that of the pendulum itself), is exerted at a right angle against the front bearing surface of the "top" trunion pin and its socket and against the rear bearing surface of the "bottom" trunion pin and its socket. Do I think the heavy weight is a recipe for a ruined trunion? No, but instinctively, I try to avoid additional weight on my pendulums.73, Miltk4oso

HI HI ... yes, I work on this every day. It is called code practice!
