  • Jer, very nice!. I have one safety concern. Wire colors are coded on purpose. Please wrap the green wire from the switch with some red electrical tape or heat shrink to indicate that it is a hot wire. Green should never be used for anything except for grounding. The white wire should be wrapped with black for the same reason.

    • Agreed, very nice work. Additional considerations for future builds: When painting the enclosure, do a small paint mask for the head of the contactor mounting screw where all the ground wires tie together. You might have done this and I missed it. Commercially made metal enclosures often have an inward facing 10-24 stud or similar with no surface finish surrounding the stud for ~1/4” radius for tying grounds together and bonding the enclosure ATST. Ideally, avoid use of a momentary switch for the stop circuit. It's going to be more mechanically complex to realize with your hip bar switch operation scheme, but not impossible. When you smash the bar in, it should open the stop circuit and that circuit should remain open and not rely on the contactor successfully dropping out to keep it open. When you pull the bar forward it could close the stop circuit and then momentarily close the start circuit. These are just typical machine control schemes.

  • A few thoughts, it would be a lot safer if the contactor coil was 12, or 24 volts, then you wouldn't have the potential for a short in the micro switch wiring causing a fire, as well, remove the risk of a hot wire energizing the metal push bar ! Other option, you can add a ground jumper from push car to lathe base pan (don't rely on pivot bolts for ground, you'll be lubricating them, an oil isn't a good conductor;) 3D print a plastic cover, and add fuses for power legs going to micro switches. Two last items Add a ground wire to switched outlet, the two screws holding it in are not a code approved grounding method And use a star washer under head bolt that's holding contactor to box, and a nylock nut, so you're guaranteed a solid ground years from now

  • The easy access to the power switch is a very good idea for convenience and safety. The control scheme, with two switches, one normally open and one normally closed is a good basic control idea. I remember doing the same to control a turntable in a small broadcast booth in 1969 or 1970. The biggest criticism I can offer is that you should be consistent with wire color codes. Using the green (normally a ground) as your common wire to the switches is generally a no-no - but if you wrapped some black electrical tape around a short portion of it, you'd be indicating it is not a ground wire. Same thing when using a white wire for hot or a black wire for neutral. You'd use white tape in that last situation. Your videos are always entertaining, you present your topics very well, and I very much enjoy watching them. Thanks, Jer!

  • I can see a whole lot of this build is to allow for oil to flow into the pan. Cables are being routed over the table to avoid holes in the pan. This is a 9" lathe built around 1950, which doesn’t hit speeds you’d require coolant or make so many chips you’d have tons of oil. But it’s beautiful and who cares!

  • I love your videos Jer. Because you are not an electrician, here is an electrical tip for your consideration. Placing the ground wire on the contactor nut / bolt is not recommended, as it could be loosened over time, or during fault-finding etc. Better to relocate it to a unique place. A stud is always the preferred fixing for earthing purposes. This simple modification could be carried out when you modify the contactor enclosure for reversing the motor or when you modify it for variable speed etc in the future. I already see comments about the choice of wire colours, those issues can also be easily addressed in the future updates with coloured sleeves or tape. You know what these wires are today, but in decades you or the next owner will find it much safer and much easier to conduct fault-finding with the correct colour coding on wiring. Keep up the great content Jer.

  • Would you consider adding a secondary start-switch in series with the microswitch at 12:18 so that you cannot inadvertently switch-on the lathe (say - if your apron gets caught on the switch-rail, or if you have pesky visitors). The secondary (momentary) switch would be placed far away from the rail, of course, and switching on would become a two-handed affair.

    • This could be accomplished with a simple ON/OFF switch on the power cord to disconnect power to the whole thing without unplugging. The switch/outlet combo device might actually be able to be rewired to do this, or more simply, a handy box with a single switch could be added beside the micro-switch box in front.

  • Like the emergency stop feature and the NVR feature. I'd personally be tempted to add a lock-off switch (even just an SPST switch in the 'Stop' line) as I can see if being possible to knock it on as you're leaning over it. It shouldn't but all that's got to happen is your belt catches on the switch and it could be pulled - especially with such a short throw. Paranoid? Perhaps, but cheap insurance. Interesting way of doing it though; I'd never have thought microswitches for that problem...and that's not a criticism in case it comes across that way!

Then to use the chuck key you have to remove the power key, hence cutting power and preventing any restart (as the micro switches would be disabled) and vice versa.

I think the only violations were related to using green insulation wire for something other than ground, and using white for something other than neutral. Overall I feel like it was a pretty good installation. Way better than most DIYers. Maybe some of the wire termination and combining schemes are not technically allowed either (I'm not sure).

  • Might I recommend installing a locking stop station in series with your NC (stop) microswitch and placing it in a visible location. I'm only worried about accidental starting of the motor. Say you're leaning over the lathe and your belt gets caught on the paddle, you could easily start the machine and put yourself in harms way. A locking stop station would allow you to have a way to lock out the motor quickly without unplugging the unit. It would also allow for a layperson to stop the machine in an emergency without needing to be taught where the stop mechanism is.

It does seem that if you are, say, changing tools or in the process of mounting a workpiece in the chuck, and reach down into a drawer to grab a wrench or chuck key or shim, that you run the risk of clipping the horizontal switch on the upstroke from the drawer, and accidentally powering things up in an unsafe configuration. Just imagining; you will have a better feel for how it will work in practice. Cheers, John
