CUTTING SERRATIONS ON BRIDGEPORT MILL 668 tubalcain 

You bet!

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

That was exactly what I thought when the little tab thingy popped up, He's Tilted the head !!!! Many thanks lyle. The finish looks beautiful if that's possible for metal?? Thanks from lancashire UK.

@@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.

@@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.

I have planned a long time ago, a two Part video. Part 1 will be the poor man's method, and part 2 will be the rich man's method

Glad you enjoyed it

Thank you very much josh. You made my day

I hope you realized that you just cracked me up

Why? Well if I tilt the head then I will have to tram the bed.

Tilting the head is a no-no, but if it must be done here's a tool for getting the table back to perfect alignment without removing the heavy vise. photos.app.goo.gl/zKpdEDgdrLbNwTps5

I thought you would "rather take a beating"

You beat me to it!!!!!!!! Lol! I think he said “I rather be dead than tram the head”! Lol

They are realy expensive

@@yak-machining Many machinists don't know how to make their own files but it's about the same process.

I am planning a to part video On trimming. Part 1 will be the poor man's method. Part 2 will be the rich man's method

Thanks

I put this video Off for over a year because of that

That was not a nod, it was a rotate. Nodding is front to back which a Bridgeport will also do.

Good lord, man. Can't she blow down between batches!? 🍪🥛🍪

I thought the same thing!

😄😄

Nice job on removing those Broken off bolts. Always a tough chore

Broken hardware happens more often than I would like! Thanks for watching me do the tiny jobs. 😎

I know, I have a severe beating coming

@@mrpete222 sometime I could do it in 5 mins and other times it took 2 hrs. Its just how your luck goes. Best of luck and stay safe.

That is great, never heard of that

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.

@@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.

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.

this is tilt, not nod, no?

@@derschwartzadder True. but the same.

Exactly, It will be a double header. For man's method and rich man's method

Hi Buddy. Nice to see you here.

Look up a 90 deg carbide mill drill. That should do it without having to tilt the head.

Nothing is tastier than a Bridgeport vid with Bacon!

Go to RU-vid channel Tom’s Techniques he has an example of how to do it there.

I would like to see Mr. Pete's take on it. But we have to wait for his fairweather foundry to open for the season.

Code 3 Response Videos thanks for the info I checked it out and a couple others thanks!

You are 1 in a 1,000,000

@@mrpete222 maybe? Or I'm just crazy. But then aren't we all?

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.

You could use a 90 degree head like this - ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-VZHn36LcKmE.html

Thanks

30 lashes And then salt water. There will be 1⁄4 coming Video Ion straightening it back up

Many times it is just the belt at fault. JIM

Looks like he made a simple mistake and did not feed out the saddle far enough before moving the table over.

Carbide

You would need to use carbide to face off the old serrations first.

Grinding stone would be the best. Carbide or CBN might do the job, depending on the jaws.

Surface grinder on a mag table? About 5 minutes total setup and grinding time total. Easy, peasy.

@@stanervin6108 the jaws are not removable

In my mind, A knurl is round

No. The depth controls the width.

@@RambozoClown thank you
