BORING ON THE BRIDGEPORT MILL part 2 Criterion Head tubalcain

[@davestahl572]

In the machining world there is boring, and then there is boring. None of the videos have managed to put me to sleep, and as a "new" machinist, anything new is always useful in the way of knowledge. Thanks again for your sharing what you know.

[@mrpete222]

Thank you for watching, and I am very pleased that I did not put you to sleep

[@MrDan27611]

@mrpete222 Or adults. I've gone from a curious hobby welder who couldn't sharpen a drill bit to being in danger of actually producing something machined, threaded, etc from my shop. MUCH of what I've learned has been from your videos and now that I have experience, I still bring up your videos on specific tasks to refresh my memory and check my setup. As a self taught student, it's the assumed knowledge that leaves me behind most of the time. Thanks much! I'm really enjoying learning from you.

Mr.Pete, I'am so grateful for your videos, (I bought a new home and it didn't have a workshop, it has a garage but the wife wants It for cars! Go figure!) so I've been busy the last year n built a little 200 sq ft shop. I now can start my Hoglet engine and needed to make a 1" hole(R.50) and only had 3/4" end mill but I have a brand new boring head! (Never used it) so I followed your instructions and I used it on the crank web and it worked great!!!!!!!!!!, Thanks for your videos they are invaluable!!! (Ps I also watched the video on drilling and reaming an accurate hole, and that worked great also)

[@RightOnJonCrane]

Always great to come back and watch some of the old videos. Mr. Pete Re-Runs! 😃

[@mrpete222]

Thanks

[@newstart49]

Thanks for the videos. You have helped a lot of people. For myself and I'm sure a lot of us, you will be a youtube legend.

[@russtuff]

Great boring pun, and very nice video! I hope you are not getting burned out on making these because I look forward to many more.

[@jamesdepaul3410]

Your videos are great, Mr. Pete

[@mrpete222]

Glad you like them!

[@xull1x123]

Rudi Marczi: I think he knows this. He's just demonstrating how to properly bore on a mill. Imagine if you have a 4 cylinder engine block and you're trying to bore out the cylinder bores this technique would be extremely useful there.

[@CoolAirVw]

at 1:14 he says, "it would be easy to chuck it on a lathe ect"

[@centurialinc]

Love your videos! been watching for a while. I linked this video in one of our videos. Keep them coming. and thank you for teaching your skills It has helped me a lot! Best Matt

[@gbowne1]

I love the Criterion DBL202, 203 and 204. They are really nicely made. I have both of those size boring bars. APT is ok, but I prefer insert tooling. I belive that Criterion makes their own bars.

[@mrpete222]

@MrDan27611 Thanks for your support--glad I can help. Good luck on your machining.

[@13young]

Do you have a video about speeds and feeds for the boring head?

[@G1951-w1y]

Boring some holes today. Had to come back and get a refresher course before I started.

[@mrpete222]

👍

[@bufferbrown]

I don't think you mentioned the orientation of the tool in the head. Should the flat face of the tool meet the work at 90 degrees or should you twist the tool slightly to give it a bit of rake angle?Thanks

[@mrpete222]

@psient Thanks for your kind remarks. I have been a shop teacher for 34 years full time and then part time for 11 years. I DO know taht you cannot assume anything when explaining things to kids. The devil is in the details.

[@egx161]

Your indicator read .005" when you moved the boring head .010"? Can you clear this up? You mention that the head is direct reading, so moving the boring head .005" read .005" on the indicator? Thanks. Love your videos.

[@BenPC2013]

Any adjustment of the boring head is a movement radially, but when it cuts it removes material off the diameter.

[@egx161]

Thank you. Yes, that makes sense. Its the difference between measuring a line and a circle. So when you dial in .010" on the Criterion DBL it cuts .005" out of the bore.

[@Icutmetal]

Emilio Gonzalez Aaaand you’ve got that backwards.

[@twodoorcivic8062]

@@Icutmetal so if i dial 5 thou on the dial it actually takes 10 thou?

[@Icutmetal]

@@twodoorcivic8062 Yes.

[@fireblade639]

Hi mr. Pete... your videos are really helpful... can you give me a tip here...i'm making a speed reducer, really small, i bored 4 holes for ball bearings but i need to lock the bearings in place with internal lock rings but i can't imagine how can i do this cut, is there any suitable way to achieve this??? Or i need to make use of a cnc mill??? The stock does not fit on my lathe. Thank you so much, if you can make a video about this it will be really helpful.

[@mrpete222]

That's tough one. I would use Loctite bearing mount.

[@fireblade639]

mrpete222 thank you mr. pete, the locktite worked very well, the bearing stoped walking out, i think my problem is alignment, was out a little bit, i see your shop and looks very clean, how often do you clean your working area???

[@Camerashooter]

Another great video! Thanks for posting.

[@ajwx2007]

thanks for your videos - they are very helpful!

[@stevenparente8978]

Great Concise videos.

[@psient]

Hi: I wonder what happened to your ability to post videos for those of us who revere manual machining. I have referenced you to my students. I have also started taking classes in machining at the Community College where I instruct psychology classes. Having been an instructor for over 10 years I appreciate your methodical, patient, deliberate portrayal of what would otherwise be a complex task. Please respond. Dr. Jon Mettrick

[@phastings246]

Did you make an error in the edge finding video? The center of rotation of the edge finder is .200. Half of that is .100. The centerline of a 5/8 inch bar is 5/16, or .313. Yes. So, wouldn't you have to crank the bit in .313 + .100 or .413?

[@blakerichardson6277]

Yep. If I already had a bore I would sweep the center with a test indicator to find my center too. Edge finders are junk if you need to keep the bore concentric to the od

[@capriracer351]

How Boring!! LOL... Just kidding! I used the same type of boring head you had in your Bridgeport for enlarging and deepening the valve reliefs in the pistons that are in the engine of my race car. It worked much better than a flycutter for that application, in my opinion..

[@mrpete222]

@earnyourkeep101 Sounds like you have a great career ahead of you. Enjoy those BPs.

[@the4thj]

2019! This is still useful, because I have to use my LittleMachineShop Mill to bor a larger hole in a Grizzly saddle to fit on my Central Machinary 12"x36" lathe. Wish I had the real equipment stuff.

[@mrpete222]

Yes thanks

[@JohnDavidDunlap]

MrPete says "cri-te-ri-on" and Kieth Fenner is says "cri-ton". I don't know what to do!!!

[@mrpete222]

Don't do anything

[@jhareng]

Mean while back at the ranch.

[@Trajiq187]

To be honnest, CNC is BORING as fuck... I'm glad i have a manual machining job! A lot more challenging.

[@mindfreak001009]

thanks God that this boring is not boring..lol

[@WojciechP915]

I'm sorry but this was your most boring video yet. Great job as usual.

[@trexinvert]

@earnyourkeep101 Dude, get a hold of solidworks or inventor cad, and you "too" can become an engineer. More importantly make real parts that you need. Not just wait for an engineer to hand you a drawing(with missing dimensions and non-standard drill call-outs). Good luck.

[@jr9950]

Yeah you could probably assume the audience is not a bunch of total morons and move a little faster, but I appreciate your detail non-the-less.

[@Fixinthatupvideos]

T=up

[@rudimarczi9468]

It would have been easier just to chuck that bushing in a lathe to bore the hole out larger!
