Re: Variable speed motor for lpi?
@Ciuens yes - that seems to be a viable solutions for smaller overheads. But maybe not enough torque to drive bigger rigs. I was wondering, how low 3 phase BLDC motors can be throttled? I was looking at some motors, they are rated something like 24V 3000rpm - could those be throttled down to .. say ...

Re: Variable speed motor for lpi?
Hmm .. thanks for the in-depth info @soulbear . My motors are 12V and I am running them at 12V with a PWM controller. The have no torque at all below 20% duty cycle. If I understand you correctly, you "over" powered your motors?

Re: vms 80 Neumann Joana Polinska Replica Clone
That's sad. I wouldn't have expected this. I honestly thought that he burned himself with his purchase and was too chicken to admit it. But - well - an IP from Poland is pretty convincing evidence. I seems I might be too gullible. And no - I don't want to buy the Brooklyn bridge.

Re: Complete novice, looking at this rek-o-kut on ebay - any
Well - I never had one of those heads. Can't say much about it. My first head was an old Presto mounted vertically, blew the coil (with the Sony amp) learned to wind my own coil - and much more important - learned why it makes sense to have an inline fuse :) The seller won't accept returns and didn'...

Re: Complete novice, looking at this rek-o-rut on ebay - any
Jesse - my take on amplifiers - don't bother with vintage tube stuff. You'll always chase hums, don't have enough power or all the other little bugs in old electronic gear. I am using a 'normal" consumer grade Sony amp and it works like a charm to drive my Grampian. As to the overhead on Ebay - well...

Re: Variable speed motor for lpi?
The other way to go .. and I haven't investigated this yet, would be a stepper motor. Lots of torque, very good accuracy and highly flexible in terms of different speeds. Disadvantages are: More complicated to set up and to run - most likely need a computer (Arduino?), those things are noisy, you'll...

Re: vms 80 Neumann Joana Polinska Replica Clone
No. I don't believe that one can get a viable basis to build a lathe for 500 Bucks. However - sakuszi says that what he bought is ok. So - I am officially dumbfounded now.

Re: Variable speed motor for lpi?
I did a lot of math on this question. The adjustable PWM range doesn't give you enough torque to cover all necessary revolutions for 33 1/3, 45 and 78rpm. Even if you concentrate on 33 and 45, you would need to be able to manually "rewind" the cutter head because the motor doesn't give you enough sp...

Re: Poltz Freres Lathe Photos
I was interested in this lathe and made the seller an offer, but he never responded. Given the fact that this unit is in Europe I decided to not pursue it anymore. Did you buy it?

Re: vms 80 Neumann Joana Polinska Replica Clone
Well - I started a thread about that a few weeks ago and decided, not to buy this "system". Even before I didn't expect the system to work, I didn't expect the cutting head to be useful. All I wanted was some basis I could use to build upon. The situation is difficult from my perspective: While ther...

Cutting 33 1/3 RPM
Ladies And Gents: I had a hard time getting an acceptable 33 1/3 rpm cut on my Rek-O-Kut / Grampian. It was rumbling, the highs were pretty much absent and I was almost willing to give up on the idea of being able to cut 33 1/3. But than again - I don't give up easily. So I took everything apart - t...
