Well this is the difference between using a hand tool as opposed to
a bench mounted tool.
A Dremel, whilst a good tool, requires you to use one hand on your
work, the other holding the tool. Basically two hands is a firmer
grip then one hand.
If you invest in a polishing lathe, or a bench grinder with tapered
spindles you will find polishing to be much faster, and you’ll be
able to get a better polish.
The main considerations for a bench mounted polishing tool are dust
extraction, eye protection, and attention. The bench lathe will have
a lot more power and revs per minute (depending on the brand) than a
Dremel, this means that if your work catches, 1) you may find your
work rocketed into the back of the lathe, 2) you may find you hand
being polished, or 3) if you are polishing chain, you may get a few
really nasty whacks (or worse). Like any tool you need to be careful
Initially when I was polishing 3 foot lengths of steel to a mirror
polish, I was using a drill, and this was fine in that I had to
secure the job in a vice and was able to use two hands on the tool. I
bought a bench grinder, some tapered spindles, and a series of
polishing mops. The job was much easier, and much faster.
