Please keep making these short little snippets for us. Nothing elaborate so you don’t have to spend a lot of time. Your knowledge and teaching methods are so good! I know you want to sell your courses but some of us can’t justify the expense. Thank you.

Bob, that was terrific. Thank you for taking the time to walk us through. Please ALWAYS assume we are dying to see EVERYTHING you're up to. Toolmakers are a special class of machinist, that means even great machinists have something to learn here....hooo yeah. Thanks again !!! I'm pretty versed in Solidworks, but when you started talking about the PRE-CAD days, my head whipped AROUND. If you have an old project laying around with drawings and wanted to show us how clever you are

This is 100% best advice; what you'd expect from a solid journeyman. I've been doing it like this for over 40 years like this, so does everybody in toolrooms everywhere. Sometimes I first put the big face against the solid jaw and take a cleanup on one side first. Then I flip the block, and with the milled side against the jaw, take a cut on the biggest face so it cleans up faster. The rest, exactly like Phil says. Then side mill one or both ends. A trick I've used forever - have a precisely ground vertical 1/4" slot in the back jaw for a 1/4" tool bit or key, and butt the block up to it for squaring up the ends. I'm so old that, as a test, we apprentices had to cube-up a shot-put ball in a shaper. Our squarehead boss timed us and checked our work with verniers and a square. Those days are gone and people are learning machining via KZread. Keep it up Tool and Die Guy!

Thanks for your comment!

That's exactly the wat I was taught and i still do it that way after 50 years.

Thanks!

I was taught this way in trade school many years ago, and it has never failed me. Good lesson Phil

I was taught this trick many years ago as well, and use it often. One thing I would add. It may not be a factor on CNC mills, but on Bridgeport style mills with adjustable heads, you need to make sure the head is trammed in square with the table. It doesn't make any difference what technique you use, if the head isn't square, you CAN NOT square your part.

Applies equally to CNC mill, method of control doesn't matter...

Thanks for that sir! Quick and dirty and very informative!

Great job, I feel like I just took a thirty five year blast in the past. I learned this in high school. And validated this process in trade school.

Phil, forgive me for calling you Bob. Multitasking.

nice...brief & to the point. solid video my man 👍

yup....I learned this years ago...love yr videos man...

Thank you! Im hoping to start this job soon, Today had an interview and goofed up because i didnt know how to answer this in words really. it was a bit awkward interview. I like yourself LOVE Milling, I like Turning too, but Milling is fun. I tried to explain that its a very similar world based on practically the same machine moves

Excellent video , thanks

The toolmaker who taught me cool tool room tricks, he had two 1.0" ball bearings for odd shaped parts he would use. Same principle as the round stock.

I actually prefer copper wire in two places, high and low on moveable jaw. Did some time in a shipyard and a lot of our material was CNC flame cut steel sometimes 4-5 inches think and only needed one face cut with a step in it or a hole or something. Copper wire was the only real option when you needed to hog a little and do another operation like that with it without machining the flame cut faces.

I was taught that instead of a round bar to use a ball with a flat. I would be curious to see what worked better.

@@TheToolandDieGuy Who is Vince? My instruction stressed the 123 rule of clamping. So in this example the fixed jaw will supply an effective 3 points pf contact, the base iv the vise will give 2 effective points of contact, so the movable jaw then ves 1 point of contact, with the resulting machined surface being square to the face of the block adjacent to the fixed jaw. Hence, my curiosity about the effective difference between the two techniques. Not trying to pick a fight, either technique may get to the point of "good enough" but are they equal or is one measurably better?

The mill should get you within better than a thou. if done right.

If you need better than .001 on a raw block, then grind it. ?

Wow !!!!!

No rings , watches, jewelry, LONG SLEEVEES,APRONS on a lathe (let it get caught in leed screw!)

i was convinced at the start this is going to be flawless. dont use that rod. outdated from the civil war days. take a piece of aluminum stick and mill it off leaving a pad. stick it in from side like a handle placing the pad about 3/4s down. dust off next surface. Rod is not used--especially by experienced machinists. the side that is against the rod-moveable jaw has to be very good. list is endless why not to use rod. using the pad method it can be .050 out of square sawed bizzarely makes no difference. you cannot use a rod as shown unless you get lucky. if I were to use the old rod thing and forced to do it I would stick it in about halfway and crush down on it. rod method is not used--it dates back to old books from the civil war here is how to get away from the rod method: take an aluminum rod such as shown. now turn down clearance leaving only 1/2 inch or so. use that and crush down on it. once you reach that point "the light will come on". what you will end up with is simply taking a strip of aluminum 6 inches long and milliing off one side .020 deep and you will never vary from it untill you retire

I actually have and use a plastic screwdriver handle with a pad on it.

I take a rod with a flat on it, Dead soft material and put the flat side on the work piece and the round to the moveable jaw. Instead of line to line contact between the moving jaw and the stock the flat displaces any deformation
