Well heck. Ignorance is certainly bliss. It would appear there is a certain misunderstanding of "Facts" and "Proof." Alternative facts and alternative proof are of no benefit to anyone.
Every Gunsmith I have ever known has a Dremel. Most use a remote head and foot switch. WE don't Poo Poo Dremel tools. We Poo Poo the amateurs whom use them without any knowledge of what to grind on where. Or how for that matter.
Machines don't mess things up. The people who operate the machines with no knowledge or training use machines to screw things up. Some presumptions presented of Proofs are no more than an expression of stupidity.
So, please be so kind, the next time you jump up on YOUR soapbox, make sure first to peek in and count the machine tools we use. Perhaps we should count the cost of my Mill agains your entire operation?? The Lathe?? 4 different stand alone polishing machines. 3 different bench top strip sanders, Blueing and Plating Tanks, oh, and let us not forget the flexi shaft Dremel that I run with a knee switch (foot switch mounted sideways).
Since the entire argument is actually caused by unskilled operators, I would suggest we quit throwing clods at each other and get back to sharing toys and playing nice.
