Wonderful, old fashioned, quality education. Old videos are always amazingly good at that.
You should check out
Periscopefilm on RUclips they have about 7000 films
This guy needs to learn the basics again himself.
I know you have experience, but I think is always better to use something else to point the parts instead your fingers .
seriously! he keeps getting so close to the fly cutter.
Very instructional videos! Thank you so much for sharing!
Please keep your fingers away from moving parts. :)
It is downloading and you have to understand that is the best compliment!
thank you for uploading these videos
This guy doesn't use lubricant ??
I wouldn't mill anything unless the tram is perfect.
Thanks mate for this video
Thanks much
15:10 personal note
Creeped me out watching him stick his booger hooks in close to the fly cutter. Good video, just a bad safety demo.
You also indicate your vice so that it is parallel and perpendicular to your machine head. When you know your vice is square to your machine, there is no need to use this method.You can rest your raw material on parallels.Rotating your part 180% after each cut,this will square your part.
Never put your hand near a spinning fly cutter.If this guy would speed up the spindle he would get a better finish.
the step of tapping the part to be level with a parallel is stupid. You rest the part on the parallel that is sitting in the kurt Angle loc vice.
+David Ramey Vise.
+David Ramey The point is that the part needs to be made flat and parallel, but is currently a rough cut. If you rest an uneven surface on the parallels, then you're going to be cutting the top surface at some random angle that might be far from optimal. Conceivably, if you had cut it close enough, you might even go below the final part size at one corner.
After he surfaces the first face (and files the burrs), he re-uses the convex backstop piece against the now-flat surface. Shouldn't the convex piece be set aside, or placed against the front side of the vise? When using that convex backstop, we're not really aligning parallel to the back of the vise.
Watch it again. He turned the freshly machined surface forward and used that against the back jaw of the vise. The face against the bar stock is presumably still rough, but as long as the piece is oriented square to the spindle before clamping, and there is still enough contact on the movable jaw from the bar stock spacer, he's good to go.
I don't need none of that fancy machinery shit. I just use a cutting torch and a file. Works great for boat anchors and paper weights.
Putting his hand near a moving part? NO ,no, no! A file is not made to be used in a back and forth direction. Forward only is the cutting action. My, and this guy has an M.S. and Sc.D. in mechanical engineering with a minor in electrical engineering from M.I.T.?
He lifted the file on the backstroke. Lightly dragging the file across the work isn't going to hurt anything. Get a life.
Curious what this guy's credentials are?
John Dozier "Dr. Vaaler received his B.S. in mechanical engineering from the University of California Berkeley, and an M.S. and Sc.D. in mechanical engineering with a minor in electrical engineering from the Massachusetts Institute of Technology, where he was a faculty member for two years teaching graduate and undergraduate machine design. He holds 21 patents and has 4 pending."

Took 2 minutes to find with google
Ronan Rogers, Nice, and he still finds time to make videos to teach the undergrads to use the machine shop. John, what are your credentials?
