Re: Troubleshooting Dead unit
I want to thank everyone for their suggestions, which seemed particularly good.? I was able to print out the schematic, thanks. I started trying to measure voltage on the control board.? Nothing.?

LMS also has a good troubleshooting guide: < https://littlemachineshop.com/images/gallery/PDF/drivetroubleshooting.pdf > Having? said that, a close visual inspection is always a good first step.

Had a similar problem with my 7x11 and track it down to the connection to the carbon brush. Good luck

Re: Troubleshooting Dead unit
How far did you check power?? As in, is the control board even getting power (past the fuse, mag switch, e-switch)?? A VOM is certainly your friend here and even beyond that a scope isn't

Re: Troubleshooting Dead unit
And this site has more detailed info on the (probable) controller board, but honestly, unless you’re adept at repairing complex electronics, if it’s the board, getting a new one is the easiest

LMS has wiring diagrams; one will probably match your lathe. https://littlemachineshop.com/reference/wiringdiagrams.php?srsltid=AfmBOoomtz5VTCGGi7-i5pLeaC6KYiHvsVAkwc4sbB0ZL3nuyrhti7ln? Wiring

Troubleshooting Dead unit
My 7x12 Northern Mini-lathe has suddenly quit working.? Previously, when I flipped the switch from forward to reverse I heard relays click.? Now nothing.? The fuse tested good.? I did not see any

Lots of interesting ideas.? I'm particularly interested in working with heating the PVC for future projects.?? In this case, using the PVC coupling, once it was mounted and centered it literally

Once again an e-mail string has fallen off its original subject and is wandering around aimlessly. Can we please get back to the original subject of mounting a plastic elbow on a lathe or just stop

HCL? Reads article… yup, HCL. Yeah, don’t heat up PVC so much where it goes past being all gooey, it releases chlorine (nasty stuff) that combines with water in the air to create hydrochloric

An anecdote? Wow ! At least READ what you post. exposure to fumes from an overheated (362 degrees C) PVC extruding machine. Fear mongering, pure and simple. [email protected]> wrote:

Not bull... we've had workers that had to be hospitalized due to heating PVC. Do what you want.? Not fear mongering.

Re: Mounting PVC Fitting for Boring
Bull.... Overheating / burning it is a problem you want to avoid for more and bigger reasons than some fumes. Heat it by immersion in boiling water. Ventilation is also welcome, always, for many

Re: Mounting PVC Fitting for Boring
I can confirm that Mario's method is an excellent one. In addition, if you want to restrain the diameter, use a glass jar into you push the elbow in after hot air heating it. Don't use

Re: Mounting PVC Fitting for Boring
In the coupling I bored the diameter out about 0.08" at the opening and tapered it about 1/2 degree as the bore extended into the fitting.? The vacuum fitting and the saw fitting required slightly

Re: Mounting PVC Fitting for Boring
Visit a local auto parts store; they'll probably loan you an exhaust pipe expanding tool that'll do the job. <

Re: Mounting PVC Fitting for Boring
Better still. Turn a wood dowel to the desired ID and use it to expand the PVC after slightly heating it
