The Secret Society of Lathe Trolls

Hi Sameal, For testing for run-out and if things are running true engineers often use a Dial Test Indicator similar to this :- 25mm-Digital-Indicator.jpg I got mine from digitalmicrometer.co.uk for around £40/$60 The scale is switchable between imperial and metric measurements with an accuracy to 1/...

Hey Bryan, When you work out your deal with the "Bone Yard" guy, on the other Russco's could I prevail upon you to see if you could source for me an Auxililary Counterweight, the one that fits on Mini-stem just beyond the main Pivot, and that runs parallel with the main Tonearm Stem? Mine's also a P...

Hi Bryan, Yep, when my Sparta GT12 arrived from the U.S. it too had a Crappy Warp and Flatspot on the Idler Wheel, what's wrong with people parking them in neutral eh? After quite a few attempts over a couple of months I eventually managed to contact a Mr Skeeter Nash, who has acquired the Russco br...

Hi Bryan, I hope you have better luck sourcing one of these than I did, a task made more difficult for me by virtue of me being the other side of the pond. I've got a terrific Russco Turntable too (a Sparta GT12) which I have thoughts of using as a Lathe drive, and have had the devils own job in try...

Hi Stevie, Both motors look to be set to drive the Lathe Platter Rim, I figure speed selection is/was done via the first lever on the top-plate which selects drive from either the left-hand motor or the right-hand by a Huge (About 12in Diameter) cam arrangement under the Platter, which engages left ...

Hi Trolls, Included here are some of the Photos of my very recently acquired MSS Recording Lathe MSS Disc Lathe Photos2.pdf This Lathe is a Perfect basis for a restoration project, which was my intention when buying it for around £800. It is however much too large for my very modest home and I must ...

Here's a few photos of a Compact & Beautiful Lathe designed and built by A R Sugden, that was recently for sale in the U.K. on the ubiqutous Bay, enjoy :- Soulbear

Hi There,
Did you check out flo's production database at http://www.floka.com/cutters.html ? There's some data sheets posted on there which you might find useful. Hope this helps Soulbear

Hi Michaela, The trials and tribulations of getting a good vacuum set-up eh? I'm currently mulling over some similar design issues and what I can tell you for sure, is that if you double your pipe diameter, as a rule of thumb, you would quadruple its volume and ergo reduce the flow velocity by a fac...

Hi sakuszi.
Well done you Soulbear

Hi There,
AHEM!!!

Hi sakuszi, The points you make about loudspeaker efficiency are really quite interesting, they're about as efficient as a Steam Engine so not the best in terms of converting inputs to outputs eh? A quick Sneaky Beaky on Wiki for a brief synopsis on Loudspeakers reveals Typical home loudspeakers hav...

Hi Fellow Trolls and before I begin, Festive Seasonal Greetings to each and everyone. My Recording Lathe adventure continues a pace, and I have just purchased a Trio of Ancient Mono Cutterheads with which I'm having enormous fun bringing back to life. I have however given some more thought to the me...

Hi There,
I'm pretty sure the best person for you to speak to/contact would be Trolls member Stevie342000, I think Stevie is well clued up on all things Sugden so send him a PM, I hope this helps Soulbear

Hi Trolls, I would like to pass on this little tip which I have found most useful, for those Trolls who are maybe Hobbyists cutters, or who are like myself new to cutting and are or may be complete novices, and who would have serious reservations about spending a fortune on state-of-the-art microsco...

Hi Alfred, If you use the Two wires which are delivering the Audio to, and driving the Cutterhead, and connect these Two wires instead to a Loudspeaker, If the Loudspeaker works OK, then you will have eliminated the Audio Signal Path as a potential source of the troubles you are experiencing, that i...

Hi Alfred, Silly me, I thought about and then forgot to mention it in the above, but the simple expedient of substituting a decent wattage 8 Ohm loudspeaker in place of the Cutterhead ensures that the amplifier is delivering the goods and thereby eliminates the amplifier/audio chain as a source of t...

Hi Alfred, If the coil resistance is sound, it could indicate there may be mechanical issues to resolve. Remove completely the centering tube assembly from the base of the Cutterhead. Next CHECK that the Armature has the free gaps/space to vibrate and CHECK that it moves freely and is not binding or...
