tubalcain is amazing! For someone with his experience to take the time like he has to help us all out around the globe is phenomenal use of the internet and youtube. Thanks you from so many of us, that learn from your videos !! Tubalcain, you are the man !
Just trammed my Bridgeport with the same back actuated indicator you used. I got it on eBay, but didn't know how to setup it up in the spindle to tram with the accessories I had. As expected, Tubalcain had the answer, as I used the bent rod trick you demonstrated. I'm 70 and just getting seriously into the hobby, and your videos are both educational and inspirational. Who says you can't teach an old dog new tricks? :)
"After all we're machinist and we're striving for perfection, usually not getting it." The man speaks the truth. Thank you again mrpete222 for sharing your knowledge.
I'm looking to buy a Bridegport down the road. I was originally going to become a machinist but missed one math class to many and ended up logging for 25 years. Even the little I did learn in machine shop served me well through the years. Shop class is essential. Great videos
learned more in a couple of your vids then I did in school I can use your info for my home shop without trying to figure in out and taking hours and wasting time Keep teaching I'll keep watching
i don't know if anyone has told you, but you have a voice for radio. just stumbled upon your videos tonight, subscribed, and will enjoy watching while i'm lapping up the gravy at work. thanks for contributing so much.
I can't tell you how much I have enjoyed watching your videos and learning very useful information from them. I am a beginner machinist and eager to learn how to do things the RIGHT way. I'm sorry to hear that the Tubal Cain in England is no longer with us, but I am so glad, at the same time, to hear that you are still living. I have bought many of the English Tubal Cain's books and have found them quite useful.
hello my name is Beto...and you just dont know how much u help me with ur video thanx for ur time on doing this let me tell you really quick...just got hire at this company and tomorrow i have to zero out the head and i had no idea...but with this.....mannnnn ill b good to good. thanx so much AND GOD BLESS YOU!
Your one of the smartest machinists I've seen on youtube so far. I can't say anything wrong with that. I like how you remember to say "check it again once it's tight" . Most people I see never do that and it's usually likely it could move. People I work with square the head but they don't do it like that with the indicator. I try to tell them they're wrong. You are right that the bigger the sweep of the indicator the more accurate it will be. if you use large diameter cutting tools for instance
You are the man and thanks for all of your videos. I'm a self taught machinest, been looking over the shoulders of a lot of good ones for the past 20 years and have learned a lot. Your videos fill in the blanks and I sincerely appreciate it. BTW, your last statement is so true!
I just wanted to thank you for the video . It is great ! thanks - I have "played"with a mill in the past and never been shown how to use one correctly. This really is helpful. Thanks again!
very educative video,thanks for sharing your know-how with us... now I know how to indicate table on my mill.Only used for hobby,I am not machinist...but spend free time with my mill and lathe in garage...thanks from Croatia--good work,keep going
Dude, this guy is the greatest. This video is awesome. I almost pee'd my pants when he says 'naturally, I went the wrong way' (at 5:52). That's pretty much the story of my life. But anyways, I have to go tram my spindle now...
Great stuff, Professor. I recently got a great deal on a 14” rotary table and have to move my vise for the first time since originally installing and tramming it. This will prove very useful! Thanks for sharing your insights.
Well, ..Thankyou so much for this vid. As a CNC mill operator, I haven't had that much helpful info on knee mills. Actually, we have an Acer in our shop that I've use a little. I think it's like a BP 30 series. It has the taller table. But again Sir, Thank you!
During moving my "J" Head Bridgeport across my shop to its primary location I rotated the head 360 deg. to counter ballance the machine. Now that the machine is where it is supposed to be, can you explain the process of truing the head prerfectly perpendicular to the table. As a beginer mill opperator your videos have been extreamly helpful! Thank you for all you do...it is great
Most don't seem to know what those are for. Do you know what the lug and hole are for on the back of the ram. Most don't and I see it painted all the time.
No cnc or computer can replace good old fashioned experience. I have been a toolmaker for 41 years and have probably forgotton more than a cnc machinist will ever know. Cnc fantastic for volume, but costly for one offs.
Never knew about those lugs either, I lowered my quill & used a machinist square against it. I just built a 2 indicator tramming device and gonna try it out tonight. You ever use one that has the 2 indicators on a bar & if so any tips or opinion on them?
Every time I need help, your'e there. Many, may thanks. It's the starting point that I was looking for in order to change or clean or adjust the brake. And clean everything at the same time. Warm regards from Québec.
Mr. Pete, your description of the tramming process is straight forward and i like your indicator holders. I can't seem to get the axis that you didn't show to come in. It seems like i have dyslexia in that orientation. Can ya help out a stu-nile old man! Mike
I move the Z axis though and not the indicator dial to zero. I don't like to touch the indicator, I find it easier to line up the arrow with the lines that way for me.
You can also put the machine in neutral and turn the spindle with you fingers, but you have the be careful that you don't bump your indicator or the piece holding it. That is what I do because the machine I use is a variable speed model and you can't easily get to the belt.
no thanx to you ...lol the funny part is that today first thing as soon i started my shift...i when and cut me a piece of rod to put my button indicator on. and it did the job more easy! and fast...really thanx so much...i will do the same one day for some kid out there.....thanx and god bless!!!
Great video. Very informative. It's splitting more hairs, but if it's important to anyone, (those in the gage/fixture trade) lowering the quill all the way down will exaggerate your reading. Meaning, if your indicator is showing out of square about .001", with the quill all the way down you'll be showing two or three thousandths out. I notice in the video that he had the quill down, but did not mention it's importance. My trade is all about splitting hairs. Sorry!
@@mrpete222 I have a riser and I didn’t think to scribe a transfer mark. And I don’t want to take it back apart. I thought maybe machinist school taught a procedure if you don’t have a mark or it’s illegible. Thanks you really remind me of the guy who worked for my dad that first taught me to use these machines when I was a kid in grade school.
Dummie All: Clamp something on the table or vise that’s square with the front edge of the table. Loosen and oil the ram so it slides freely forward and backward with the ram lever. Clamp a dial indicator in the chuck. Indicate the squared bar on the table by moving the ram with the lever back and forth until the indicator reads zero. Mark mating surfaces for alignment.
Hey sir, do you know how to wire a drum switch for reversing a single phase 120 volt motor? If so, can U recommend a youtube how-to video? Thanks, take care from TN.
Tubalcain is only half way done tramming in the head, he needs to do the same procedure on the front & back of the table or "Y" axis. He needs to "nod" the head up or down until the dial indicator reads the same 0 as it does in the "X'" axis.
You showed tramming only the X axis. That was easy. Next time show doing Y. If the radius of the indicating arc is about the right size, the front will move about twice as fast as the rear. It is still much harder. If the head isn’t trammed there will always be a step between cuts when facing a workpiece. Also, if the knee is moved, the center of a hole will move sideways either in the X or Y direction. Good teacher.
Hey Boss ive been watching your videos for awhile...We just released some new high perf carbide endmills (one for non-ferrous and one for ferrous) wondering if you had a job anyway if you wouldnt mind working with me and testing some free tools
Howdy. Yes, I would like to receive a bunch of carbide end mills. Send me whatever you want, I will eventually show them in a video, and be using them on a project in the Bridgeport mill. You can find my mailing address, in this TH-cam video. It is called -------winter night school video courses by Tubalcain. Thank you very much
Ok these cutter would be for cnc milling but i will find some others tooling more suitable for bridgeports like hss or cobalt end mills or drills, which by the way, we can definitely save you money on..But this is not a sales pitch, I think your many videos are very informative and certainly your knowledge is helpful to those less experienced or just learning machining. I was looking and could not find your email as i wanted to ask you about doing a short interview. We have a fairly large following of customers weve built over 10 years and many of our new customers seem to be new machine shop owners. We get a lot of calls at tech support from customers like this who would benefit from what you teach. Doing this interview, which would be like 15 minutes or less, would introduce them to you and your videos would give them a great resource for general machining tips and education. I know it would be a good thing for both of us for sure..Our blog is midwestsupplyusa.info. Perhaps you could inbox me there or sales@midwestsupplyusa.com
That's the same failure as you did in the previous video. As soon you will move the table, you will go out off alignment. The alignment which you are doing is only for one point, for drilling holes without moving the table.
I just wonder who the 4 doofuses are that disliked this video. You got to be a doofus to dislike this video. Thank god for old masters willing to show us their secrets and skill for free.
Too much room for error. Instead, put a 1" micrometer standard in the middle of the table. Fit a test indicator on 4" radius arm on the spindle. Move the table to the left, and touch the indicator to the standard, raise table till the indicator zeroes. Set Z axis dial at zero, then lower the table .200" Move table to the right and turn the spindle 180 degrees till the indicator tip is right over the standard. Raise the table .200" and note the indicator difference. Adjust by 1/2 and continue.

+Rich B Thanks for watching-glad you were amused
Thank You, Sir. Fast and to the point.
@mrpete222 I've worked on Bridgeports for 40 years and I never knew what the notches on the machine head was for!! Pre squaring the head!
Great stuff, Professor. I recently got a great deal on a 14” rotary table and have to move my vise for the first time since originally installing and tramming it. This will prove very useful! Thanks for sharing your insights.
I bet that rotary table weighs a ton
@@mrpete222 Yes, Sir: function aside, it is a serious chunk of metal. Back-breaker.
@Volvo745T THANKS for your encouragement.
Thanks for your interest

I was wondering if you tram the head off of parallels or off the table. Parallels probably?
Side to side is the easy part. It’s indicating the nod that gets me.

What is the best way to straitened the turret perpendicular to the table??
Just use the protractor. It is so large in diameter, that makes it extremely accurate

which model starret do you recommend 649-1 (Graduations: 0.0010" dial 0-100) or 649-5 (Graduations 0.0005" dial 0-1000)

he said he did that off camera.

Jimmy Stewart is a machinist?
Yes! It's a Wonderful Machinists Life!

Are Pro tractors the same as amateur tractors but they do it for money?
Depends on the precision you want.

Adjust by 1/2 and continue.
No--he is from England. And I think dead now.
are you a mason
WHY DIDNT YOU INDICATE YOUR Y AXIS? I THOUGHT YOU WERE "TRAMMING THE HEAD" HELL ALL YOU DID WAS ADJUST THE HEAD TO MAKE X GOOD .
At 1:20, he says he'd already done that.
