Line Boring PART 1

[@martinwalters1954]

I like your demeanor as well as the way you explain things Keith. Lot's of guys try to be "entertaining", which makes them look like buffoons. You stay professional and focused on the details while still taking time to point out tricks of the trade as well as the point of things. I'm no machinist, but you earned my respect. Thanks for the videos.

[@mickking9622]

I often perform line boring and ID welding. I think you would more understood by people who have little experience if you were to demonstrate the procedure while performing no a real life job. I appreciate your effort in sharing your knowledge.

[@joshuapruden6497]

Im a Machinist from Manchester Connecticut. Your videos are awesome!

[@successfulcatastrophe3480]

Great video. Keith is clearly a master of his craft.

[@billdlv]

Great video, always good to watch someone who really knows their trade.

[@S10Electric]

I made a similar setup but used a self feeding mag drill. works great for feild work. Liked your Cartoon assisted drawing! Thanks for posting

[@KeithFenner]

@submarineboat Your welcome, I know its a while down the road, before that stage of the game but open eyes work better if they have a hint, on to what to be looking for along your way getting there. Keep it simple and I'd be glad to help if you need! Keith

[@AtelierDBurgoyne]

Keith, web search landed me on this nice two-part series. Quick overview and very useful! Daniel

[@JimmysTractor]

I saw a video on a line boring kit. He showed the setup and used cones- only problem is that the cones were centering themselves on holes that were no longer round or centered on the original hole. I'm thinking I'll make 1in thick pillowblock plates. I have truck axles that I can turn between centers for nice boring bars.

"CAD"...lol ~ classic Keith comedy...Keith, really enjoy your videos I always learn something, thanks for sharing your expertise bro...

[@petermoale2116]

Hi Keith, you are a real professional in your trade ! May I ask your opinion of the holes going through the boring bars ? Do they absolutely need to be square, or may a round hole, with a side hold that is drilled and taped for a set screw be just as good ? I know that the end of the set screw must have the cup or similar end ground flat. Thank you for your opinion. Regards, Pete.

[@nealk6387]

Will you please grind a carbide tool bit! I can't seem to get it right.

[@passenger6735]

Keith, what is the name of the adjustable tool holders that you use in your boring bars please. I've rewatched a load of your past videos and I can't find it. Im certain that you bought them from MSC. Thanks bob

@@KeithFenner Thanks Keith.

[@dzljon]

thanks! Keep on repairing America one project at a time.

[@martinwalters1954]

Another astonishing project.

[@erikgrahn3363]

a vertical turret lathe(specifically bullards either spiral drives or cutmasters dont matter no difference) is my favorite machine to run. secondly is the horizontal boring mill (give me a good lucas and im damn happy. GREAT MACHINES for great machinists

[@stanleyrodgers3375]

This is a perfect example of how powerful sharing on KZbin is! Looking at Harry's (FactoryDragon87) vids and the nature of the work he is currently doing on his horizontal boring machine, getting set up to be capable of line boring would be huge for him! Plus, he already has a really big angle plate he could mount a flange bearing on.

[@aryesegal1988]

killed me with the CAD remark - cartoon assisted drawing, brilliant..! ;)

[@FactoryDragon87]

Nice video, Keith! Lot of practical information! Keith, please say me one: from what kind of steel are made the boring bar? Does it is special alloy steel and does it is chilled? Thanks a lot!

[@FactoryDragon87]

Oh, thaks! I have the question for U.S.A. mild steel: how much C (carbon) it to contain? Does they to contain any/ other alloys? I ask for this because I want to compare view.

[@JimmysTractor]

What do you think of a large timing belt on a 10:1 reduction from a 1hp 1720rpm motor?

[@FactoryDragon87]

In my land mild steel is from SAE 1003 up to SAE 1030 (1035) carbon from 0,03 to 0,3 (0,35)%. Thank You for explain!

[@KeithFenner]

When bars are made up for production and or for one use, they may be made up and hardened and some other tricks done to them, but I for the most part just use mild steel or leaded stock, because I may modify the bar for the next use and like the freedoms, that allows me. ;{)---

[@clintonmanchesterjr3523]

What LPD were you on

[@dzljon]

who makes your drill press with the 20" faceplate?

[@stanleyrodgers3375]

Mild steel is a plain carbon steel, no other element is specified in its composition except carbon; for mild steel carbon content ranges from 0.16% to 0.29%. An example is SAE 1018, plain carbon steel with a carbon content of 0.18%, commonly used to manufacture cold-rolled steel bar and plate here in the USA.

[@tcauto256]

just recieved the MSC tool holders thanx for the tip:)

[@KeithFenner]

.15 / .20 C .6 / .9 M .04 P and .05 S those are at least 30 year old numbers from one sorce, you can reserch new info from the new manufactures of today. all I know is if we ship it out, to have something made, it don't come back way! LOL ;{)---

[@kingabdulaziz646]

What type of bearing ? Answer me please , fr my final project

[@gripWIN]

What would be your objection to: No More Line Boring Boswell

[@KeithFenner]

I would have no objection if the machine had started with this system and changed them out, in a scheduled manor. They still need a true straight bore to work properly. ;{)-----

[@127069]

looks usefull for use after line boring and not having to sleeve out but they never wear round!

[@KeithFenner]

Sibley, they stopped production back in the mid 1990's ;{)-----

[@laurentcnc6662]

Really laugh with the Cartoon Assisted Drawing, guess the license soft is free :-)

[@byrysh]

That is a boring bar, ya should add an exciting paint job... O.o lol

[@SupraSmart68]

Great video Keith! A bit boring through, I mean though. Sorry, I was errrr, bored? Holy smoke, my yokes are so worn out I bored myself! :-p

[@ROCKNTV1]

keep the vids comin Keith, ;)

[@FactoryDragon87]

Thanks a lot!

[@GnosisMan50]

Wow...hard to believe that this video is only 6 years old and Keith looks so much younger and slender. Of course, I got 6 years older too.

[@KeithFenner]

I bought my PlasmaCAM...

[@KeithFenner]

we made it on location. ;{)---

[@IB-1963]

Hey mate - you keep saying "Morris Taper" - it is actually "Morse Taper" - Glad to help you poor Yanks learn to speak English - no worries from Australia - Glad to help you Yank Tanks - Go Trump 2020

[@JimmysTractor]

We need more mates like you in the USA. I hope you haven't been effected by the energy initiatives of your great country. Seems china is the only one making money on the windmills and solar cells. Wish they'd just build a bunch of nuke plants and be done with it.
