Default Laguna REVO 12/16 - any information out there?

I am looking at getting the new Laguna REVO 12/16 and I am having a hard time finding any information. I found a video about making the candy dish about it on YouTube, but not really finding anything else. Has anyone purchased this yet? Does anyone else know anything about this? I stopped by my local Woodcraft and they have some on order but don’t know when they’ll be coming in. Thanks for any info.

I guess I missed a couple on YouTube, thanks for responding! I am really excited to see this one, it looks really great! Still hoping someone here got their hands on one!

Been looking at it myself. My speed controller seems to be on the way out in my Delta 46-460. So I was looking at this one as a possible replacement. Got to eyeball it back before Christmas at my local Rockler ‘s store.

As opposed to using a Vary resistor pot as most DC lathes do this uses a different way to control speeds. Not sure of any other lathes that use this technology. So this could be one of those test subjects. But here is some reading on it for those interested. Pulse Width Modulation.


It is up there in price though.

Thanks John for the update on the pwm... Reading got deep on there but basic explanation broke it down in simple terms.

Thanks John, So If I'm correct, they're using a 555 timer to oscillate the resisted output voltage and now it's more of a digital timing voltage moreso than a analog on/off? Am I understanding that correctly? Isn't this kind of inline with what Dyson and Tesla have been doing for a while? If it is, that's really kinda cool. I'm surprised we haven't seen it before now. With that said, the pulse could be varied and would allow the full torque of the rotor to be envisioned and full potential throughout the full range of the motor. I don't know, maybe I'm seeing this wrong. But, this could be a new step in lathe tech.

I've also been waiting for this to come out. I missed the part about the speed control using PWM, but I'm kind of surprised that nobody's used it before in a lathe. Definitely the way to go.

David I believe you are correct. This technology has been used in other fields such as LED lighting and large light banks. Why has it not been used in motors such as used on a lathe I have no idea but could be a wave of the future and we can see prices fall if more companies use it. Seems like a better way to control speeds torque and keep everything clean. Have to wait and see as more people get these and try them out but for now the old DC motor with its resistive pots work too.

I hope so, this could rid us of variable pots(at least in this field) and let the voltage flow. This would be a good thing.

Edit: I'll take that back, it would rid us of variable resistors, variable pots would still give us variable speeds, that's the good thing.
