Twl, They have standard ranges of musical boxes with 100, 64, 32 and 16 notes. Some play one tune, others several. I have several,including a couple that are very old (perhaps 100 years old) and have been passed down to me. Whilst I wouldn't want to make one, I believe there was an article in ME showing how to do it, back in the late 40's-early 50's.

Now for something completely different. Today I called in on my old mate Dick, who's not long back from his jaunt around Blighty & Euro. Showed me a music box he'd picked up in Austria & from the few clues we can gather from it, it appears to have originated in thar country. Very old, but working well. But here's the thing - the drum, which is about 1" dia by 2 3/4" long, carries literally hundreds of pins which hit the keys? - these tiny pins are no more than probably 0.005" in diameter & maybe 1/32" long. The drum cams along to play four different tunes in succession. Now the question - just how on earth were them that pins put in the drum and, for that matter, what are they made of? They appear to be steel of some description, mounted in a brass (bronze?) drum. Oh, instead of the usual 16 or so keys, this thing has about a hundred or so. Absolutely exquiste workmanship, bit I'd sure like to know how that drum was made. MODEL ENGINEERING DISCUSSION LIST.
