The Secret Society of Lathe Trolls

White vinegar is supposed to be good as a bath to remove rust, also making a baking soda paste with water to scrub parts down with a tooth brush. I've seen folks say that boiling water with baking soda is great for removing paint from metal parts, but no mentions for rust.

That isn't the case here. The K10 is a rim drive system where the rubber tire is on the outside of the platter so the size of the tire determines the speed when driven by the motor. The motor is a fixed 1600rpm with a metal capstain that slides over to connect with the tire. The platter already run...

There is no idler involved in this situation, only the capstain on the shaft of the motor and the rubber tire on the outside of the platter. Should I not be calling the "sleeve" on the shaft of the motor the capstain? Example: 2" capstain (motor) at 1600rpm, 36" platter = 88.88rpm 2" capstain (motor...

Thanks! I've seen him referenced before related to the 6n rollers, but from his website it looks like he only does small rubber jobs less than 6". I also didn't realize he's here in Michigan as well. I may give him a call this week and talk shop. I was also looking at buying some square o-ring cord ...

Has anyone replaced the tire on their K8 or K10? If so, where did you secure the belt/tire? I had thought mine was okay flipping it inside out but there is too much vibration from a bad spot where it was packed with the tone arm rest mashed against the tire and a flat spot on the inside so turning i...

These are listing I was watching for historical reference, interesting progression, from oldest to most recent -

Someone snagged a great machine in the working 6N.

Thanks Steve! New thread coming up!

It's just a knurled knob that screws into the mount that the cutting head is on. The head mount on the 75a has a larger flat piece in front of the pivot than on the K8. The K8 doesn't really have much space to mount a dashpot in front of the pivot. I think that's why they eventually went with an adv...

Are you sure it was a K8? I've seen lots of pics of the K8 but never one with a dashpot set up. Do you mean the 75a?

I was watching that one on eBay. You have the basics of a K10 model. Lots of missing pieces including 2 of the 4 worm gears (assuming there was one on the platter with the other under the platter as pictured). Most folks only use 2 of them anyway, the two that control cutting from outside in, the ot...

You can but it would be labor intensive, it's how picture discs are made. Black puck for the core and then clear film on the outside minus the paper "picture disc".

Received my copy yesterday. The printing on this run is darker than what you see in the above pictures so some of the photographs are dark and you lose some of the details.

Thanks for the heads-up, ordered a copy.

It was changed from $2500 BIN to an auction with an opening at $1800, $3000 BIN.

A Presto K-8 in good cosmetic condition ended for less than $300 yesterday.....wild stuff.

I've browsed through about half of it. Some interesting articles on cutting styli both sapphire and steel, introduction of heated cutting, transition from standard to microgroove, and many pics of lathes in action; primarily Prestos and a few Scullys. Will definately download the PDF for better read...

It's a scam every time.

Your best course of action is probably to take it to a machine shop, have them drill out the old screw, and create a new tap on the opposite side of the capstan.

I wondered if there was concern about the release being unnecessary or could harm the fidelity. Great video above. At the end of the video what is the material that gets caught on the stylus? Is that residue from the mold that was stuck in the grooves or something else? Cat hair?

I was reading up on casting and for basic shapes, it is recommended that a release be sprayed in the mold to help with removal once the resin hardens, would this be good or bad in the case of making records?
