David,
I don't know about the Tacho being 'Posh', although it seems to give reasonable results. I was given it as it was going to be skipped. I must try to check it sometime.
I agree with your comments about speed. After all, we're not generally in the business of removing the maximum amount of material in the minimum time as Industry is. I generally just dial up something that looks plausible. On my old belt drive lathes I generally leave it where it is unless it's wildly out.
On the subject of home-made Tachos see attached. Once again I captured a few of these on the way to the skip. If I remember rightly they are part of the Plessey 801/802 Shaft Signals System. As you might imagine it's built like the proverbial Brick Outhouse to resist the rest of the heavy machinery associated with the Winder. That really is a chunk of 6" x 4" steel angle in there. However, there is also a nice slotted disc and a couple of sensors on the little PCB, which might assist with your experiments. I believe I have your address here somewhere. Shall I put them in the Post?
