Presto K8 Dashpot, damper
hello does anyone know of a dashpot that would work for the Presto K8. Or a alternative that could fit on it?
i saw a picture somewhere on the forum of the original damper that fits on the side of the cutting head.
The reason i need it is because i seem to be getting oscillations and i noticed the cutting head sort of bounces when cutting a record.
Also when i look at the grooves on the record there is some sort of pattern where it goes from dark to light.
Any suggestions will help me out

Take a look at the VMS Solenoid thread I posted a link to an alternative there

Re: Presto K8 Dashpot, damper
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?
Re: Presto K8 Dashpot, damper
Hello, it couldve been for the 75a. The 75a looks to have the same cutting arm as the k8. the only difference i see is that there seems to be a screw behind the cutting head to where the damper connects to.
I just need to know how the damper that is mounted 75a works so i can probably fabricate one myself.

Re: Presto K8 Dashpot, damper
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 advance ball on the K10. I started working on a 75a about a year ago and have made very little progress. Thread here: http://www.lathetrolls.com/viewtopic.php?f=1&t=4090&hilit=75a&sid=e040e1507e73672a033a5bc19972dda7
I can take some pictures of the 75a mount this week if you are interested.

Thanks for the pictures and links to the other topic you started.
I am curious to what kind of material they used for the dashpot for the 75a.
