CUTTING SERRATIONS ON BRIDGEPORT MILL 668 tubalcain

This is an absolutely wonderful video, thank you so very, very much for posting. WOW!

well done , thank you for making videos.

This is awesome that you are doing this video. Perfect timing because I still have vise jaws that I need to resurface for my Columbian

Would it make a smaller slot using a smaller end mill?

The grooves are certainly straighter in the mill han the shaper provided.

This is a good technic to improvise... Surely I'll give it a try. You can also try to use a single cutting edge, V-shaped endmill.

I saw the thumbnail and thought, a 90 degree vee bit would have saved you a beating. Thanks for going all out for us.

Can't wait to see the finished project Mr Pete, what a clever idea

Awesome . Going to make me several sets ! Love it !

Thank you Mr Pete. It looks great.
Its funny how when you look at it, one time the pattern looks concave and sometimes convex.

Even though I've been a machinist for many years I just love watching your videos. I know a lot of what you teach but there is always more to learn! I can't wait to see you angled vise jaw project!! 💪

It makes me appreciate my Bridgeport Rigid-Ram CNC mill from about 1980. A few lines of G-code and watch it go.

I must be the only one who doesn't hate tramming the head. I actually enjoy the challenge.

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. Josh, Ontario Canada.

Great job sir, today I learned something new and useful. thank you very much for your dedication to teaching

Finally! I don't have to buy a Shaper! Thanks, Lyle!!!!!

👀🇦🇺🦘👍

First thing I thought was 30 lashings and salt water beaten at the stake. A few others beat me to it Mr Pete. Thank you

“I would rather take a lashing than tilt the head”. Hmmm

Hi Mr. Pete! Have you ever done a video on Bridgeport head rebuild? H&W Machine Repair out of Ft. Wayne, Indiana has rebuild kits including belts, bearings, etc. No offense intended but your step pulley head Bridgeport is very, very loud. A step pulley head should be whisper quiet. Mark

Did this many years back before I owned a mill with the table saw! It was aluminum not steel, but came out very nice. Thanks for the video and looking forward to further videos on this project.

I've always enjoy your videos, but what do you think of a ball bearing instead of a round pin? And using a ball end mill for the round pocket in both half's of the plates, there would also have to be angles on the long edges?, So Grateful for all the videos it's such a wealth knowledge that people for years to come can use and benefit from

I have never seen a Bridgeport (or any other mill) mill in person. I am quite impressed with this machine. Wonder if I could use it in my woodworking shop, probably not!!

was that a screw-up at the begining but still looks great

Thanks again Mr. Pete.

As a tool maker for the last 35 plus years I’ve retired happily but I do miss running the Bridgeport the Reid grinder and the Clausing lathe I love your vids they take me back to simpler days/nites your a good man

@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.

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

Thanks kind sir rather hypnotic and inspiring.

I was hoping to see this on a curved surface, like an extra deep knurl.

awesome

Nice!

You make a job that would seem a faff and time consuming, seem very strait forward and easy.

I will be making that pivot jaw very soon. Wish I had seen that design 35 years ago. Very handy indeed. I have just used vertical round scrap similar to the pivot point on yours so I only get a small tangent point of contact. I will soon have another specialty tool in my Arsenal. Thanks for the idea !

Good to see ya back at it, Mr. Pete

is there any difference between a serration and a knurl? Stupid question I know

Wow. You tilted the head! Thought you hated doing that?

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.

Great lesson, thanks! Yes that's me. 73 years ago!

It just gags me to tilt the head on my mill

I have never moved the head of my Bridgeport from 90 degrees. This is a good project to make me experiment. Thanks for sharing!

You got a shot of both of my unfavorite things to do, tilting the head and cleaning up the chips, I don’t like either one. Great job!

👍NICE work!

Very fun to watch, thanks pete!

Sir, you are an absolute pleasure to watch work.

Thank you sir 🫡

Very good video !! Tilting the head grrrr lol great work

Thank you Mr Pete

Hi Mr Pete I've been searching through your 5 year old or so videos for the Quill light you have on the Bridgeport can you tell me what video it was and brand of light . Thanks JM
