I have a Union Gradute Lathe,with a controlled Speed Inverter,but,no Digital Readout.I would like to know what speed my lathe is turning,is there any reasonably priced tools on the market,that can do this for me?Something that involves ,not to much wiring up ,to get it going,or,preferably ,a piece of kit ,that can give you a digital readout,with no connecting to do,if that is possible?.
Yours kindly Paul.
