This Part Should Be a Test For all Machinists........

I'm the last guy to back down from a challenge, but machining this part checked all the boxes for THINK AHEAD or fail miserably. Its the feed link for the PM Research mini milling machine. Take a Look !!!

Sooooo, the next machinist challenge for the BarZ get together? I have learned so much from watching your videos, and for that I am truly grateful

[@courier11sec]

As you were discussing setting up the angle in minutes and second, my brain screamed, jumped out of my head, and ran out the door never to be seen again. I guess I'll have to get into management..

[@sumduma55]

Look up sexagesimal math. It's a bsse 60 mathematics system used by the Samaritans and babylonians. Anyways, the easiest way to relate to it is with a clock that has a hour and minute hand and a seconds hand and reading the time. Navigation coordinates are based similar too. Since the gearing of the rotary table takes it to a full circle, following these concepts makes sense and reading the scale starts to make sense too. It allows you to position the piece any place in a circle reletive to the center.

Grinding Vises in sizes from 1 1/2" up to 3 " are super handy and cost almost nothing. i bought two RÖHM grinding vises New for less than 150 Bucks. i know they are import vises but they are accurate to almost a tenth in terms of squarness and paralellism and flatness . i highly recommend a tiny one and one 3 vise. the options u can do with them are so versatile !

[@tims6870]

Old stock? Rohm is one of the best brands around for tooling. Toolroom quality from Germany. I just looked on their site and a genuine 34mm (1 3/8ths?) Vise is €157 on its own, buying that and a 75mm one for $150 is an absolute bargain!

The process here is amazing. This video is full of gems. Also - the early stages where the key set up moments are shown quickly at higher speed both saves time and provides a full view of the important aspects of the set up - that's excellent presentation. I wonder if you would mind making the short refresher on using the rotary table dials its very own video to make it easy to find in the future? I know you have other videos on it but that was the best summary and presentation on how the dials work that I have seen. Cheers Joe - making a complex little part like this by the numbers - inspirational.

WOW Joe! This was some impressive work on a milling machine. My initial take was that this part would have been done on a watch makers lathe like a Lorch. Damn this was good! This part would be easy if it was several inches long. But the small size and requisite precision was impressive.

[@colfergusson4242]

I'm not an engineer/ machinist but watching this is truly inspiring, the skills, knowledge and how you present you have Sir is nothing short of amazing, I do hope there are apprentices learning off you at the shop, it also has to be said that the KZbin videos you present to all of us are highly educational and helpful at whatever skill level and knowledge base we have.

LOL I was forced to move. I just moved my crates containing my wood and metal shop to a storage yard. As much as I would love making steam engine parts on my monarch EE lathe, I am having to build a new shop. All old world timber frame as I have more logs than cash. So this metal head engineer was dragged into serious woodworking to allow me to run metal machines. Joe had been a god send in entertainment until I get up and running again. His experience makes the complex look easy. And the best question to ask in complex wood or metal is this: How the heck am I going to make this without cocking it up! Likely Joes greatest contribution to us.

Great presentation, great camera work, and your techniques are excellent.

Keep up the great work!

As usual Joe another awesome video masterclass. Your methodology and thought processes regarding workholding are truly mind boggling to me as a hobbyist. Right now my mind is well and truly boggled 😮 your shop gem of using a vice in a vice for holding parts is something I used while following your tutorial on the pm research #1 engine, cylinder oblique ports. Such a simple idea yet it gets you past so many workholding problems. Also your mini fixture plate is a must have item. Finally Joe I would recommend your mill skill maze to all budding hobby machinists this teaching aid is superb for honing ones skills on the mill. I will leave you with one of my own "shop gems" if you mount the mill skill maze on a rotary table on your mill, then you have an almost infinite variety of maze/puzzles to traverse. Never get bored doing that. Thanks for all that you do for us mere mortals. 🏴󠁧󠁢󠁷󠁬󠁳󠁿 Regards allan.

[@tabaks]

Actually, Vernier markings are an equivalent of (1'-10") apart. But, as you hinted, that is rockets science for some people.

[@devmeistersuperprecision4155]

I managed to scarf up a Moore rotary table from the old Rocky Flats Atomic Bomb facility. Many of my tools came out of atomic energy facilities. The level of rotational precision is insane. One might consider at first using a rotary mill accessory such as a volstro head or KT 2D rotary mill. But the intersection between rotary motion and linear motion at the projected angle is tough to meet. Here, using a toolmakers vise on a rotary table is more straight forward. But you will definitely need a jewelers loop here!!! Great idea putting the toolmakers vise onboard the rotary table.

[@chrismoule1]

So its just like an analogue watch to change the angle

[@sumduma55]

Yes. It's a base 60 math originating with the ancient Sumerians and babylonians called sexagesimal math. It's an easy way to divide a circle up that has stuck around. It's usage in time has to do with navigation (sexton) and why latitude and longitude uses the same degrees, hours, minutes, and seconds. It's one area the eurotrash hasn't manage to screw up because they can only divide by 10 for the most part.

Very nice video. I find myself using round stock in a collet chuck more and more for parts like these. I like making the same part on different ends of the bar so I have an extra to mess up. And I can part them off to finish length in the lathe. And my Prototrak mill. Its conversational programming is really great for stuff like this. I haven’t used the rotary in probably 2 years.

[@Stefan_Boerjesson]

As aleways, an amazing work, so well presented. I've got 3 such vises, from 1.5" to 4"... and a 5" rotating table. What an ugly little piece to make..... My little 6" chain saw needs something like that...

[@Dagonius.]

Nice! Not for beginners lol (parts flying everywhere)

[@SpruceSculptures]

It is the most 'difficult' part I have made. It took me about 3 tries too, not just one one.

[@PaulSteMarie]

Kind of surprised you didn't cut the t-nut profile first, then flip it vertical, drill the two holes and then whittle out the stem with a woodruff cutter, such that everything remains fully supported until the surfaces are formed. The mounting plate would be formed last, and then parted from the piece with the sliding saw. BTW, MSC's Interstate (aka Value Collection) little grinding vises are actually decently made and a fraction of the price of Suburban or (god help you) Moore.

[@KerseyKyle]

I did not know that Moore ever made a small grinding vise, the only vise I have seen in their old catalogs is a jig boring vise with two round rods. Herman Schmidt is famous for making the most luxurious grinding vises, but I think they are not worth what they cost when the cheap $150 import grind vises are difficult to find a flaw with, I got one from HHIP and was getting almost no deviation with a .0001 indicator while checking every surface using a squareness comparator. But the non-critical surfaces they show poor craftsmanship such as how they chamfer the edges very roughly, but on my Herman Schmidt vise every chamfer looks perfect like it was a faceted gemstone.

[@PaulSteMarie]

@@KerseyKyle Oh, that's right. I was probably thinking of Herman Schmidt. I think i paid about $60 for my 2" vise, but that was pre-Trump tariffs. As you say, non-working surfaces aren't finished well. I also had to replace the screw at one point, and I'd like to redesign the t piece and make one that won't twist out of position. Still, it works well.

[@joepie221]

@PaulSteMarie Greetings Paul. Over the course of building the PM Research machine tool line, I promised myself I'd make every effort to fabricate the parts from the material provided. I do often disagree with the material they supply for the intended part, but its a personal challenge to give it a try. I agree, this part would have been easier done from a longer blank, but there was only 1/16" of extra material on the blank. I've used your technique with much success in other projects, but for a .063 cross section coming out of an extruded blank, I would expect distortion once the arm got longer. Thanks for the comment.

Reading degrees and minutes on a rotary table is not difficult. It's the same as reading the numbers on callipers. And indeed, this is a nice example of a "delicate part".

[@sumduma55]

I think the hangup for most is understanding what degrees and minutes represent. It's not something you realize you use every day and is lot like going from metric to decimal English measurements. Even English to decimal English can be difficult for some. An example might be 1/4 inch =.250 inch = 6.35mm. To some, each version of the same thing could resemble a foreign language they do not understand.

[@mattfordsgoatfarmingtips1646]

I live in Arkansas, and from what I've seen a machinist of this quality will make $21-$29 per hour. I feel like this trade is under paid, because I worked as a tool room machinist for a few years and didn't see much opportunity with companies in Arkansas that wanted to pay well for this skill. I wound up going to college for engineering, but I would not trade the skills that I learned in the tool and die shop I worked in.
