The Secret Society of Lathe Trolls

Yes, I had found a cheap snubber on Amazon, but as you said it wasn't right for this application so I returned it.

Thanks for the info, I'll go on their website and see if I can find something that will fit my homebrew lathe.

I'm actually looking for a good dashpot replacement. May I ask what model you're currently using, Sillitoe?

Cope Plastics in Minnesota carries it.. but it's not cheap. I've bought from them before.

Wow, thanks a lot! Very interesting info.

On the topic of feedback Grampians, would a 60W-ish LM3886 amp be sufficient for driving one of these heads?

Thanks Mark! Could you share your summing amp schematic if available?

I have some black, 10" blanks that were CNC cut that I could sell.

I've been searching the forum for info about Grampian feedback heads, and found that the feedback in them is actually not like traditional feedback, but more just to linearize the low-end on the heads. Does this mean that you could run a grampian feedback head without using feedback?

Were you able to print the Neumann cone shape hole for the stylus?

Very cool, I think I'm going to do that.. Did you just use steel for the side pieces?

In your picture, where are the magnets? Are they on the top, and the sides are just pieces of steel or something stacked up?

Is there any reason you couldn't just replace the horseshoe magnet with a couple of neodymium magnets..?

One thing that always bothered me about the whole blank/stylus heating thing, especially in regards to cutting plastic.... I thought when you're engraving/cutting/whatever using some sort of tool, isn't the goal to REDUCE heat? I've heard that heat kills diamond tooling... why is cutting records any...

Hi, I'm trying to collect as many pictures as possible of DIY-type heads for ideas ... I was wondering if anyone could post (or PM if you don't want it public) a couple pictures of the underside of the Vinylrecorder head. It seems pictures of that head are pretty hard to come by, at least from the s...

That's insane. You could buy a NEW, stereo Caruso for that price.

This old thread kind of sums it up:

It's just regular old black acrylic. I've used it before with a sapphire, pretty much cut the same as clear acrylic.

Actually, when I first got the ST.150, I had to send it in for repair because the platter it came with had an awful wobble.. I don't really have any problems with it, my main problem is when the blanks aren't perfectly flat (since I don't have a vacuum system). With flat blanks, it works fairly well...

I use a Stanton ST.150, which I believe is the same thing except with the curved tonearm. I cut polycarbonate with a diamond, grooves around 2-3mil (50-80 micron). The turntable seems to barely keep up, and if the disc is warped, you can sometimes hear the playback get a little wobbly.

then i removed the vaccum by holow shaft through turntable bearing.. so i dont need a center piece. Do you have a picture of below the platter? I'm having a hard time visualizing what you mean.. and the pictures I saw on your website don't really show that. And what did you use for a turntable bear...

Yah I actually did some searching and found some posts from the past... but like you, I only found the Alan Graves method.
