Skill Means Everything
My gunsmith says they are the greatest firearm tool ever invented and they result in about half his yearly business! He says a dremmel would have turned even John Browning into a BUBBA!
IMHO, the skill level required to make the Dremel come into its own while being used in the gunsmithing trade is high and therefore not achieved by a lot of users. And from those who fail to achieve that skill level comes the bad reputation that the use of Dremel Tools in gunsmithing gets from some.
I have developed a saying, "There are three things that if didn't exist, I wouldn't have bothered in becoming a practicing gunsmith; compressed air, Q-Tips and Dremel Tools." I have both a Dremel and a Foredom Tool. The Foredom hangs in a permanent place over my workbench accessible to use around the vise. The Dremel is put away until it is needed for a job the Foredom Tool won't reach.
I agree that almost everything that can be done with the Dremel/Foredom can be done by hand. But, that takes time. I feel that after the tools and books are bought, the gunsmithing skills acquired, the workbench built....a gunsmith is in the business of selling time. Any tool that uses less time to give the same job results that hand work will should be used. Obviously, it takes some real judgement as to when it is appropriate to use the Dremel/Foredom vs. hand work.
IMHO, for any Gunsmith to condemn any use of a Dremel or Foredom out of hand is pure arrogance. And, I will bet $ to doughnuts that the gunsmith saying that has a Dremel or its equivalent stashed someplace in his/her shop.
Dremel/Foredom uses are limited only by imagination and skill.
"Bubba" has certainly created multiple gunsmithing repair jobs by misuse and lack of skill. I had a customer that imagined himself as a budding pistolsmith. The third time he brought a bubba job to me for correction. I told him that I would do the job for one consideration....that he bring his Dremel to me and to never purchase another. Darned, if that wasn't exactly what he did. I still have that Dremel today. It is my backup to my main Dremel. .......
