Thanks Julia. It was a fun project. Although I messed up the wiring at first. I should have looked at the two previous ones I made. Got there in the end though. All working fine now. Have ordered a 9 volt adapter to complete the job. Cheers Nobby
Thanks Paul. Probably less important on the Myford lathe as the speeds are pretty much present. But absolutely invaluable on the mini mill. Cheers Nobby
Those little tachometer kits are handy. I put one on my big lathe just because the selector handles can be a pain to decipher what speed the lathe is in. So the tach really helps.
That's right Tom. Although these Tachos only cost a few dollars, they are incredibly accurate. They give a clear check of the rpm, without having to think about it. Cheers Nobby
Nice neat job nobby i always save my unused power supplies, sometimes when i check the output of them with a volt meter, i find them to be wrong to the actual value they should be. Just a thought. see you next time atb Kev
I do the same thing Kev. The only one I had was this one from the drill. Obviously not suitable. The only other one I had was only 3 volts. I'll pick one up from eBay. Cheers Nobby
Hi Nobby. I have a similar tacho. The power supply is 12 Volt 0.8 amp. It also runs a digital motor temperature gauge, so it must be a common voltage. Cheers Rob
Thanks Rob. I was thinking of buying a temperature gauge with a sensor to keep a check on the lathe motor. It's an old capacitor type, which I'm sure does run warm, especially as my workshop does get very hot in the summer 🌞 well some times! Cheers Nobby
@@nobbysworkshop Hi Nobby. My lathe motor is also a capacitor type. The safe upper limit on those is 55C. I tucked the sensor in next to the capacitor under the metal cover and it works well. It's handy in hot weather when the lathe has been running a few hours. Quite cheap to buy. Cheers Rob
Nobby the sensor really should be used on its end for the magnet as you did on the milling machine. I know that you have got it working but the Hall effect device is designed for end use I know that there would be a centrifugal outward force but try the magnet on the center section of the bull gear and use the end of the sensor. Regards from Australia.
Hi David I would have done this, but on the left hand side of the bull gear the gap is only 1/8" wide. On the right hand side there's the mechanism that disengages the bull gear, for back gear operation, and this would clash with the hall sensor. I copied this set up from someone else, who obviously found the same problem. It's all working fine, but it's critical you get the hall sensor adjusted correctly. It was no problem on the mill or Chinese lathe as the sensor and magnet were square to one and other. Some times it has to be a compromise. Cheers Nobby
@@nobbysworkshop Upon further reflection, it would have been better at the other end of the spindle. Attach the magnet to the rear spindle locking collar and drill a mounting hole in the gear change cover. Sensor would have then been end on, no need to worry about cable getting trapped as it would have all been away from moving parts. Regards from Australia.
@@daveticehurst4191Hi David, as I mentioned in my video, that was an option. In my research I'd seen others do it this way. However I just couldn't bring myself to drill holes in my beautiful lathe. All the best. Cheers Nobby
Hi Mark. I haven't checked all the speeds yet, although I know they are slightly different to the Myford ones. When I've done it I'll let you know. Cheers Nobby

Very nice work mr Nobby. Interesting.
Thanks Rusty glad you could join me on the journey. Cheers Nobby
Thanks for making this video Nobby I keep thinking about adding one to my Myford. Having the inverter drive it’s quite easy to lose track of speed 😀

Hello Nobby,
A good job done there... Thanks for sharing... I would like one on my BCA jig borer.
Take care.

@@nobbysworkshop Sorry Nobby, missed that comment, that will teach me to skip through your videos 😊Regards.
@@daveticehurst4191No worries. I think a lot of people do that with my videos 😂 Nobby
Nice video Nobby, It would be interesting to see how it compares with Myfords plaque for the belt position speeds!

good video nobby
Thanks much obliged. All the best. Nobby
