Dremels are Hard

That little gyroscope writhes like a snake in your hands.  Even knowing best practices and the safest techniques learned from long experience, it is a difficult device to master

EVERYONE knows the conventional wisdom that the Dremel is where amatuer gunsmiths go wrong and really mess up their gun.  Best not use it. 

But there are things you use it on that there really no better tool you can use!  You can't just swap it out for a file or something. 

Where do you HAVE to use it?

The lugs under the barrel.  The barrel ramp.  The frame to barrel ramp transition. 

"But wait!  Why use that dremel tool for the bottom lugs? Just use a barrel lug cutter."  That was a comment in a previous post.

Thing is... I did. We do. We use a barrel lug cutter.  They are vital.  But they don't take you all the way. 

The first cutter hogs off a bunch.  You better turn the cutter the correct direction or you will round over the cutting teeth.  Always use plenty of oil.  Man does it cut away little slivers of metal.  That cutter measures 0.185" or 0.186".  After that cut, you switch to the bigger cutter for the 'finish' cut.  0.195" or 0.196" depending on who you get it from.

But this isn't really the finish cut.  This section contacts the slide release.  What is the diameter of the slide pin?  0.20 inches, give or take a tough or two.  More than 0.196 inches at any rate.  A cutter that measures 0.2 or even 0.198 won't fit in the slide release pin hole in the frame.  0.185, then 0.196, then....  nothing available.  So you gotta use your Sharpie smoke-lamp and fit the lugs to the slide release.  To get at most 0.005 inches of metal removed in the right places.  And the only real tool for this is a Dremel with a carbide bit.  I WISH there was a way to so this with a hand tool 

This, is hard.  It's hard for the gunsmith, and he has done thousands of these.  Even he messes up and has to start over on occasion.
