Lovely work opcode66.

Just out of interest, how much does your head weigh?

Both good and bad news, but an amazing recovery story for that cutter head.

This is absolutely amazing so far. Well done. Keep at it, I'll keep reading! Thank you, I really appreciate the feedback! :D I've recently rewired the controller to use a A4988 instead of the DRV8825, since that has serious accuracy issues. Not sure if I've posted it before, but this guy did some a...

Nine work. Interested to see how you progress on this one, especially the 50Hz difference.

for the jumpiness of the head, you'll want to search for a dashpot some folks have made new ones, I think they'll called Air pots, or something? But the originals are oil filled, for dampening sudden vibrations to the cutting head. Yeah, thanks for the suggestions. I have an airpot attached to the ...

Hi Stoneley, Sorry for the delay; been out of town for some time. Anyway, in answer to your questions: 1. The dashpot came from airpot.com. They will sell you a dashpot, but they also offer free samples. 2. The arduino: it's a fairly simple build using a DRV8825 library (from github), and the wiring...

I'm using a small 4040 corner bracket, with a 2020 pivot joint. I've replaced the M5 bolt/nut with an M4 bolt and butterfly nut so that the angle can be adjusted.

We finally got a 3d printer.. man these things are handy for prototyping parts! Anyway, the last two days have been about getting suction designed and built. I spent some time designing a mount for the suction tube... I think revision 8 was the final version. Here a sampling of some of the revisions...

Lovely work..

I notice the dashpot in your video; is this a pull or push-pull dashpot?

Well, now that I had a decent platter and torque, I decided it was time to rebuild the overhead to be as sturdy as possible. In this process I discovered 4040 extruded aluminium profile, and a local supplier, so that made life easy. The new overhead is now built mostly from 4040 extrusion, with a fe...

It's been a while since the last update. Life goes on and hobbies get pushed to the back of the queue behind house renovations :cry: Anyway, it quickly became clear that the 301 really wasn't up to the embossing task (Soulbear, you were completely right :wink: ). So, I set about making something tha...

1. 78s - "The literature does not disclose why 78 rpm was chosen for the phonograph industry, apparently this just happened to be the speed created by one of the early machines and, for no other reason continued to be used" from https://en.wikipedia.org/wiki/Phonograph_record#78_rpm_disc_development...

Static is evil, killed my 10 blanks! :twisted: :twisted: :twisted: Nice work so far... in terms of the blanks: I know that feeling. I'm just working through something similar myself. :cry: Just out of interest, what angle are you cutting at and with how much weight? I should probably do an update o...

Managed to miss that somehow.

Thank you.

Hi, I'm just about finished rebuilding v2 of my system, however this time I'd like to do some cutting rather than embossing. Looking at the options available on myshank, I see they typically offer three options per stylus type: S, P and Synthetic. Can someone explain the difference to me? In particu...

How fascinating, I found the Garrard 401, which shares the 301's Motor to be well "Under-Nourished" in the very subjective, non-objective "Stalling the Platter with a Finger" Test Well, that is interesting; it is my understanding that the 401 has a slightly improved motor over the 301. I recently s...

Just as an afterthought, it's worth noting that the Garrard 301 seems to have plenty of torque for embossing.

Looking good!

Makes my plain old wood and metal job look a bit simplistic!

Hi, Time for a quick update. So many things have happened since the last posting. I managed to obtain an old RCA mono cutter head, and have outfitted it with an embossing needle. The lathe is now running (mostly) and today I managed to emboss my first record onto "record shaped" sheets of acetate. M...

Beautiful work... shame my own build isn't progressing this fast!
