Hello, my name is Al.
First off I would like to say big thanks to Steve and all members past and present for sharing an amazing wealth of knowledge and experience on this site!
I have read through nearly all the posts here and have learned a lot.
Its great reading through and seeing the development / progression with lathe cuts, experiments with different types of materials, techniques etc..
It took me a while to get my head round the concept of 'embossing', at first I couldn't get it but it eventually became clear.
So here is the 'Vanrock' as shown on the Japanese Lathes thread.
Fantastic portable suitcase lathe, from the 80's I believe.
Might well be the perfect beginners lathe as it is very easy and straightforward to use.
7' only and mono, with a choice between 33 or 45 and with built in RIAA EQ, and compressor if you use the 'auto' input.
The head is stationary and the platter moves from left to right for cutting.
Comes with a 'disk stabilizer' that screws down and holds your disk securely to the platter for cutting.
So here we have the controls.Standing
moves the platter into the cutting position ready to cut.Fast forward
is for your lead in groove.Recording
is for the runout and locked groove.
And then Stop
returns the platter to the beginning position so you can remove your disk and listen!
Here's the head with screw at the top for connecting the heating wire to heat the stylus.
Stylus size is long shank presto size.
You can also see the little brush which works pretty well at keeping the swarf away from the head.
Here's some images from the user manual.
Love the drawings
Stylus changing and troubleshooting tips.
Front page, love the futuristic design - amazing!
I haven't managed to find out any info about the company (Oogi Denshi) who manufactured these, but they also renamed it later as the Atom 101.
Would love to find out more about the history and the reason for the two names as both models are the same apart from the name.
I am pretty certain that the Vanrock
came first as the manual for the Atom
is pretty much the same as the one for the Vanrock but the name has changed to Atom - but interestingly some of the pictures inside still show it as Vanrock!
Here's the specs.
So at the top you can see the frequency response for the head - 60 Hz to 8Khz.
The head itself has quite a big peak in the 1 - 2K region, but EQing the source material to compensate works.
I am able to emboss Polycarb disks, by simply turning the stylus backwards!
I didn't use the heater for this, I heated the blank instead.
Here's a rip of a polycarb cut of a demo from my band 'Otonoarukikata' that I'm working on at the momenthttp://www.divshare.com/download/25822512-ded
And I thought that the Vanrock / Atom was one of the smallest portable lathes until I found this!
The Hara Recording Devices M180
. Even smaller, lighter and more compact than the Vanrock / Atom.
When I got it the idler wheel had a dent causing a dull thud when cutting, which seems to be quite a common problem with these Hara lathes, so I am having it rebuilt at the moment, I'll report back with more pictures and info when I have it!
