[GrizHFMinimill] Re: $50 mini-mill power feed

1) It may be a couple of minutes stop to stop. But most machining requires many passes. I have used milling machines with power feeds and, as in so much machining, you want to keep things running as continuously as possible. So the risk is high.

2) If part of the design must focus on the need to smell smoke and react with a fire extinguisher, perhaps the design is a bit lacking and needs to be reconsidered (which is what I suggest).

3) For myself, I would prefer a design with a high confidence of not fizzling or sizzling as I am trying to make a part.

If you try to put a square peg in a round hole, there can be consequences.

The problem of applying anything designed for intermittent use to a continuous or nearly continuous application is hardly non-existent. And it is certainly not one that I needed to invent. It already exists.
