I've got the Makita trim router as my spindle. It is loud and the cooling air blown out of the bottom sends wood dust everywhere. Still...I like it. I had a deflector at the bottom that discharges air off the side. I need to put that back on. I also need to design a dust shoe too. I have hearing protection on while the machine is working, so the noise isn't so bad.
The issue in my shop is I don't have 220v available and the 115v options for spindles aren't so good.
