My experience is with the very nice MachTach unit, sadly no longer available. I'd agree that installing the strong, rare-earth magnets is helpful, and make sure they are close to the sensor when they

I had the same problem on a similar unit I purchased from Amazon. I tried al types of adjustments, checking wiring, etc. My fix was to use a better magnet. The magnet that come with mine seemed fine

Thanks for the replies. I used cat5 cable for the VFD controls. The magnet will only work in one direction. I get nothing when it is reversed. The power supply is from an old PC peripheral

Some of these are sensitive to whether the "NORTH or "SOUTH" pole of the magnet points towards the sensor. Have you tried reversing the magnet? Use a compass to figure which

Probably a bad unit. Best to send it back. Harry

Not what your're looking for, but be aware that most, if not all VFDs, can provide a tach readout. All that's needed is the gear ratio for your lathe. The only down side is if you change pulley

While I don’t have that tachometer on my SB 9, I do have one on my SB 13 and Millrite mill. They are usually rock steady, but once in a while the rpm will jump for 1 second and then go right back to

You might see if the power supply is regulated . All the un-regulated wall warts Ive seen had incredibly dirty power animal On 6/22/2022 8:10 PM, Mike Poore wrote:

Thanks for the offer Ron. I've asked around but not had any positive feedback. I have a friend in Waltham with a used tool store. Maybe you know him. If that's an option, he's Andy at Tool Shed. I

Let me know if you want to come and see it. Ron

I'm real close, in Woburn. Wow. I paid $600 for my 10K in the early 80s. I'm asking a few friends. Payson.

This lathe looks a little beefier then the workshop model A lathe. Is it from heavy 10 and heavy 9 linage? On Sunday,

Thank you….I am from Chicago so it is a little far…..a few weeks ago my daughter just had her grad ceremony from Smith college….that could of worked out…

Well best of luck yo . I worry about my batteries in a fire also . Hopefully I won't ever have to experience that , though we had 3 cars fully packed for a month or so last year due to

I was having a problem with that, too, but I think he missed the photo of the MT3 taper in the spindle adapter. Just sent the link to him a moment ago. We're using text & photos that have no way of

Beautiful lathe. I wish I were closer (Utah). $1000 is too little, I think. Someone is going to be delighted!

Then you must have missed the last photo I posted, which had the MT3 taper in the the factory spindle
