Tramming back to 90° is a royal pain. Usually takes me at least an hour, sometimes two!

@@stanervin6108 I can tram my mill head in both directions in less then 10 mins. Since I got my starrett back plunge dial indicator it’s made this task much easier.

[@stevewhite6252]

@@mrpete222 I've seen a rapid tram product that consists of 2 dial indicators mounted on a horizontal shaft which then mounts in the quill. Supposedly this greatly speeds up tramming. Do you have any experience with these? I too am reluctant to tilt my head.

[@ProfessorMAG]

Mr Pete, many people, even those that have one, forget the strength of a Bridgeport mill is it's ability to tilt and nod. Some will not use this feature due to a perceived difficulty in tramming the head back square. With the proper (easy to make) tool this is simple. Maybe you could show others how one can use these features more creatively. I have formed bowled shapes, rounded troughs, diamond facets and many others besides simple flat/square/round shapes. Remember, we are not simple highschool students anymore.

Mr Pete i discovered you on here back in 2009 or 10 i believe and i just have to say that you sir, are amazing! The content you share is so valuable for the people who love this as a hobby or career, and I just want to tip my hat and commend you for your mind blowing number of years spent sharing your knowledge with us all. My equipment is mediocre at best and ive tried to get myself the best tools i can rarely afford, but thanks to you i was able to make my own graduated dials, and they were even featured on Mr. Winkys 25k subscriber episode. To some it may be a rookie project but for me it was an accomplishment to make them. If not for your instructional video, it never would have been possible. Thank you so much for all you do.

[@waynespyker5731]

My second job after graduation had 20 Bridgeports, 15 journey men tool and die makers with 5 apprentices. You appreciated the pain of traming the vise then the head knowing your finished product would be to print! My first job was 18 months in a machine shop of salvaged machines. Our horizontal slab milling machine had a vertical head adapted to one sliding column all aligned with a single hand scribe mark. Taking a second person from the rear to hold/rotate the off balance vertical head during traming with a brass hammer the operator would bump into the scribed lines. If a loud thud would be heard the head had gotten away from the team wacking the table. That was pain!

@mrpete222 with the head at 45° the serration is the shape of an isosceles triangle. Thanks to some geometry trickery, that means the width of the serration is always twice the depth, so spacing of the serrations can be calculated pretty easily.

[@howardosborne8647]

Just thinking about the case hardening with Kaseinit powder reminds me of watching the local blacksmith when I was a youngster. He would use pieces of horse hoof trimmings and small strips of leather placed in a tin with the steel pieces to be hardened. The tins were sealed up with clay and then placed into the forge until bright orange hot. The tins were opened and the orange hot steel parts quenched in brine or oil. The hoof trimmings were gathered and saved every time he shod a horse and trimmed the hooves.

[@mrpete222]

That is great, never heard of that

[@garthbutton699]

I too had a neighbor that was a blacksmith but he would close up his shop when I would show up or shoo me away saying no children allowed that was in the 60's.

[@howardosborne8647]

@@garthbutton699 my experiences of the smithy were also mid 1960s. I was fascinated by the processes and alchemy of fire and metal and how pieces of steel and wrought iron were transformed into tools and implements. The old boy was only too happy to explain the processes he was using to make a thing so long as I obeyed his rules to stay a safe distance from danger. The coal merchants yard was right next door,so a constant supply of oven coke for the forge was never far away. It was the same blacksmith who would help us kids out when we were building modified pushbikes or soap box go-carts. It was a very valuable early education in matters of engineering techniques and manufacturing methods. What does make me smile sometimes is when I hear a youngster fresh from university with a paper qualification being described as M.A. Master of Arts. By any real world definition the old blacksmith and his kind are truly deserving of the title claim of Master of the Arts.

[@rogerralston2648]

Kasenit was taken off the market 3 or 4 years ago. There is a substitute “Cherry Red” or something like that. It is a different chemical but advertised to do the job. I have not tried it. There are also DIY combinations of powdered coal, charcoal, bone, leather and sugar that are used to add carbon to harden the surface. Probably better to start with a higher carbon steel that can be heated, quenched and drawn.

[@TheRadioShop]

Great video Mr Pete. Would be interesting to see other ways to do this. As I do not have a shaper and my little milling machine does not have a tilting head. Guess I could set the part up at 45 degrees.

Hi Lyle, excellent demonstration, I was planning to do just this setup shortly on my next project which is a custom putter, although I will be using a rotary table instead of the swivel vice (only as I don't have one). Cheers, Jon

[@marknahabedian1803]

For a pointy pyramid: Assuming the base of the cutter is perpendicular to it's axis and the axis is 45° to the work, then the slope of the pyramid forms the hypotanuse of a right isosceles triangle whose right angle is at the center of the base of the pyramid. The depth of cut should equal half the spacing between cuts. Of course the ability to form a point depends on the accuracy of the cutter position and depth.

Hi Lyle, The pattern looks good. Could you use a 90° end mill and leave the mill head vertical and achieve the same result, asks someone without a mill. You and the family stay safe.

[@larryschweitzer4904]

The problem with a 90° is they don't have any cutting action in the center. Grind a small flat on the end and things get somewhat better. But you won't get a true V, I don't think that would matter for this use. I'm not a fan of having to re-tram the head either. Nice project though.

[@mikepoore1653]

Which is faster between the mill & shaper considering setup time and restoring the head to vertical? More of a physics topic, but do serrations actually increase grip? I don't think they do unless you distort the surface of the work. It is a common misconception that surface area affects friction. This fact affects the design of your tool in that it would require hardening. Perhaps a toe on the end would work better to keep the tool or part from squirting out the side of the vise?
