Hello all!
I bought a 1951 square dial machine with an elsr. It unfortunately did not come with a tach. I searched around a bit for one on eBay, craigslist, and even called monarch about one but no luck. So I have been toying around with the idea of doing something sacreligious to the monarch and making a digital tach that displaced the RPMs in large numbers. I even thought about expanding on that idea by creating a heat map on the tach to represent the motor load. Even further.. adding a hour meter to assist in doing maintenance intervals. I wanted to get the communities takes on it.
1. What is the max RPMs on this lathe? I've seen 4000 or 5000 RPMs but nothing definitive.
2. How did these tachs work? Were they connected to the gearing in the head stock or were they driven from voltage generated from some other source?
2. I think I see a small hole on the bottom tach cavity where the lead wires used to be.. is that correct?
3. Is this a bad idea? Good idea? Concerns? Alternative sources for tachs?
