The Secret Society of Lathe Trolls

That pump was originally in a player piano. Alan, Good to hear from you! You are missing out on some fun here in Oregon. So, a player piano? Interesting. I also got a second one. The one I fixed is in front in the photo. The second one runs the other direction (clockwise) and has a 1725 motor on it...

Hey guys, Thought you might get a kick out of this. The motor died on my vacuum pump and it was an odd RPM (950). The replacement motor I found on Craigslist rotated in the wrong direction (CW not CCW) and was 1725 RPM. I discovered it was possible to reverse direction of the motor by swapping 2 wir...

Hi Rolandjays,
I think you have mentioned you have a machine shop. I wonder if you had played with making new springs for those? They do look interesting.

Insanely inspired, and off the charts cool. Damn.

Great update Todd! Too bad about the Orange version. It would have been awesome to have that one running for Halloween. I do like the 1.8 black one with the orange highlights though. Nice touch with the 66 insert. Great quality print as well. Looking forward to your next update. My project is on hol...

That seems like a big hunk of metal! 1 gram is quite a bit of extra mass to sling around. Wow, what a set of discoveries and failures this last week+. I had planned to do an update this weekend but all hell broke loose. Before I share failures, here is an update on the stylus holder shown in the ot...

Todd, that is the most crazy thing I have seen since the laser etched Split Enz LP back in 1980! I would love to try that out! Can I?

Zero time left tonight, but expect a big update this weekend. Replacement of the ABS plastic / Nylon stylus holder was the key. Check out that bitching stylus holder! I made that from a chunk of 1/2" x 1/2" bar stock! It only added 1 gram compared to the plastic version. IMG_2997.JPG It took several...

I ran across this crazy ad, and all the sudden I need one. I guess I need a 16" turntable to go with it. Has anyone ever seen one, or have one for sale?

All in all, you seem to be on the way to a good result. Mark, like usual you have really great technical comments and I hope to address them after this next round of tests. I have several game changer mods to apply and I need to take new data I think. I thought it would be easier to explain and sho...

I forgot to attach the noise input file... This has the RIAA curve applied to the noise source. Notice the high frequency is about 20db hotter than 1K, and the low frequency is about 20 db lower than 1Khz just as it should be. noise input.JPG Also attached is the full frequency response in tabular f...

I should also note that I made changes to the discs that glue to the drivers. This reduced the moving mass. But I still have a steel 3mm screw holding the stylus since my nylon screws have not yet arrived. Here is an updated internal view: IMG_2979.JPG Also, I took Todd's advice and used super glue ...

OK, here is what you really wanted to see.... This is the response of a single frequency test tone of 1khz, referenced at digital 0. This is the one and only frequency input and the resulting output. Before you dive into this too much, let me make sure you understand that I have not totally resolved...

The geometry of your head as mounted in the photo looks really bad. Yes, you guys were right. I started looking into all the turn table tracking error stuff (which applies to this swing arm) and decided it could be partially corrected for with an angled mounting block but decided to mount the head ...

IMG_2966.JPG Calling all trolls: I made the adapter made to mount the No Feedback version on my K11 for the first round of testing. I'm running out of time tonight but I have files ready to do a test cut. Before I do, I want to list what I'm planning to cut and see if any of you guys think I am mis...

Here's a trick that might work if it is the magnet. Just please check the polarity first. That write up won't work for the 5C head (which is what he has I think). It's constructed a bit different, so the magnets can't be placed at the bottom as shown in the 1D thread. They need to be near the botto...

I spent a very frustrating weekend messing with the Nylon Bridge product. I had about an hour long chat with Tom from Taulman 3d about the product and we went over all my settings and hardware last Thursday. As a result I dried the product for 36 hours over Thursday and Friday. Over the weekend I tr...

For a reasonable price I can order parts.... Hey, if you are already ordering parts for your 2 boards (I have 2 boards on order as well) could you order a second set of components for me too? What would be the cost? I have a power supply, chassis, and bare boards (soon) - but none of the components...

Thanks for your reply, the only problem I see is that doesn't look anything like the one shown on the vinylike site so will it work ok?........... Yes, it will work. There are a bunch of the 200ma units on E-bay right now at a good price. Go with the DB15-20. Again, stay away from from ones with -2...

Blade Runner actually works for me. I guess you could give homage by calling it something like Kunststoff V1.0.
German for plastic or some variation.
