Lathe tachometer

That should obviously read : We have the opportunity to buy them cheaply.

The Machtach allows you to enter the diameter of the work (lathe) or tool (milling machine) and the display will tell you the actual surface speed - pretty handy, no tables or calculators required. Or the rpm if you insist. Nice quick little project if you fancy yourself as an electronics nerd.

I was quite happy as a lad with a selection of fixed speeds - there wasn't much other choice. After a 30-year gap, I realised I was turning much too slowly on my son's mini lathe, and it was likely that I would teach him the same bad habits, so a cheap Chinese tacho was an early addition.

It probably only had a couple of month's use, as neither of us tend to look at it often now we have got the feel for the machine, but it was a useful teaching aid and well worth a tenner (including case) and a few minutes installation. If nothing else, its large red display serves as a reminder that the lathe is still plugged in when the lights are turned out

Price does not come into it when deciding whether a necessity or a luxury. If one wants one on a machine not endowed with one, just pay up and fit it. The facts of of pricing now and 50 years ago are irrelevant.

I’ve fitted one to my variable speed spindle (with constant speed motor) on a lathe that was supplied nearly 60 years ago. It was my choice. I will fit one to my mill (will have a VFD as well as six speeds). Again it is my choice.

That word ‘choice’ - not needed but available, therefore a luxury. A handy extra, but not a necessity, therefore a luxury. End of.

I assume it was: We have the opportunity to buy rheum cheaply.
