Noering Meccano
20-note Punching Machine Built With Meccano
by Christofer Noering (080622 MMDigest)

Hello all MMD-ers!  Using Meccano parts I built a "Perforator Simplex," or punching machine for 20-note music rolls.  Of course, some parts were to be machined from brass as the holes in the organ's tracker bar are not spaced at quarter-inch intervals.  (In fact, the spacing is a curious fraction of millimeters -- perhaps based on old French lines?) I couldn't even use my 'X'-parts!

But most important of all, it makes _holes: good ones on ordinary paper as used in printing calculators, and very good ones using plastic-coated paper (which sadly doesn't come in rolls).  Is there any independent source for 20-note music roll paper and perhaps empty spools?  Otherwise I'll have to build them from Meccano as well. ;-)

Cheers from Sweden and happy Midsummer!
