800w spindle - noise & controlling remotely

[Jonathan]

As you probably guessed, the reason I spoke in the youtube video you linked to was so that you could set the volume so that I'm speaking at a normal volume, and judge the noise from the spindle accordingly.

I doubt the spindle from amazon will be quiet as it has a fan on the end, so there will be noise created by the airflow. This is unnecessary when you can quietly water cool it. Don't be afraid of the water cooling - it can be simple and easy.

If you go for one of the better quality (and much more expensive) water cooled spindles, I'm pretty confident you'll find it's a lot quieter than the standard 2.2kW ones. The one I used here is that type, and I recently obtained a 3kW one on eBay for the right price which is even quieter:



Admittely it's a bit on the large size for your machine, but I expect the 0.8kW one isn't going to be worse. Also you'll get much lower runout (a few micrometers) with these spindles, which could be an advantage if you're cutting a particularly detailed PCB. I can post a video with them both switched on one at a time if you want to compare?

Edit: Unfortunately I don't have a new enough phone to measure sound level.

P.S. Where about is 'on the move'? Clearly the best way is for you to actually listen to one - you're welcome to pop round...
