Line Boring PART2

[@sailorssettlersantiques2114]

Seeing the Excavator Boom coming into the shop shoulda been a seperate video entitled "The Little Shop That Could!!" Great Job. This is the reality of Self Employed Mechanical Repair. You have to get the job done with the tooling you have, not get hurt, and provide Professional Results. You Nailed it on all 3!!! It's great to see Actual Repair Video's rather than Tool Company Infomercials trying to pass themselves off as Repair Video's by Guys who Couldn't Fix Lunch.

What a gem Keith love the old videos. Of all you tube creators you own this type of content - showing the thought process that goes into solving problems and coming up with creatively engineered solutions to bring things back to life again.

[@hydrodiesel]

Keith, you are a great teacher ! It is folks such as yourself, that will transfer down the knowledge about this sort of work to the younger ones who are willing to keep this trade alive. Lucky is a younger person who gets to work, AND learn from you !

[@metusa666]

Great advice i never tire of watching your videos always learn a lot thanks

[@martinwalters1954]

Mind boggling. You are truly amazing. I'm not even a machinist, but your videos express ideas, and tips usable within the context of other trades. Thanks so much. Also..your demeanor is professional yet very humble. Something which is lacking in so many other fabrication videos.

[@ypaulbrown]

Keith, so much fun coming back to a 10 year old video, your style has changed so little, you are still the Master, Cheers from Orlando,FL, Paul

[@fulltrack]

Thanks for taking the time to make this video. I have an excavator job to do myself and your insight and comments are very helpful.

[@mosfet500]

Keith, Some of the most creative work I've seen. Well done! Rob

[@pneumatic00]

I like how your wife helped you getting that thing into your shop! "Honey, I got about 2 and half tons of steel I need your help with". Very cool!

[@gregg4164]

Those are all really great ideas on how to make this tool. Excellent work.

[@MWL4466]

Nice work Keith ! From time to time, we get job's in our shop with 2 or more bore's that need to be in line. Sometimes I've milled datum's onto the piece, so it can be flipped over & indicated to machine the 2nd bore. It's a real hassle sometimes. That's a real nice set-up you made. Sometimes, if you have the time and an idea, you just have to try it & see. Necessity really is the mother of invention sometimes. Thank's & keep those videos coming.

[@KeithFenner]

@oneyaker I aquired those, track machinery rollers, from a used tool man, while I was working back in the yards, in Calif. I'm glad I found them used, they are a little pricey, new. You can find them in MSC or Mc Master Carr catalogs...

[@crocellian2972]

Genius. I love the rollers for moving the arm inside.

[@mrblack61]

I just wanted to thankyou Keith for your time and effort in these videos. Im only playing with the machines as a hobby but ive learnt so much from them. If it could, the shaper vice im trying to true up would also thank you! :D. All the best from the UK.

[@ammagato]

Dear Keith, show your professionalism when you invent the technical means to solve the problems that arise in the course of your work, congratulations! P.S. Merry Christmas.

[@TheKelstr]

Great video's Keith, got me thinking in a different direction to solve a problem I have in my shop. Your videos are just fantastic .

[@joedell71]

Wow another really informative video series. This can have so many applications.Thanks again keith.

[@KeithFenner]

Thanks for the comment and the feed about using a lot of other choices in materials for cutting bits! ;{)---

[@WAVETUBE84]

Wow, that was intense Keith! Man! Crazy complicated. And really big, bulky, and heavy! I bet you were glad when that was over.

[@therealspixycat]

very interesting pictures Keith! You didn't mention but using the drillpress is a very clever solution to make a very effective line boring setup/tooling

[@DionysiosA76]

Another great video! Love what you do with what you have.

[@ophirb25]

Very nice. Got me some ideas. Thanks for sharing.

[@KeithFenner]

If at all possible, turning all surfaces in one set up is spot on, guaranteed! but if you have to do in two set ups, the reach and dialing both surfaces, will be in your control and your workmanship expectations, will be your call. ;{)-----

[@KeithFenner]

Thanks for jumping in and adding the feed on the bits! I use them also, but sometimes I skip over, or forget about things that have been around for ever! ;{)---

[@airedalepete]

Great video Keith! Track machinery rollers may be listed as 'machinery skates', which is what we call them in the UK.

[@KeithFenner]

@joydon1100 Sure: In MSC catalog, Low carbon steel square tool bit sleeves, are the correct term. 1/2" size is # 82432287, should be helpfull Ref's, if not find in with square tool bits...

[@KeithFenner]

They are two different line boring set ups, the self aligning bearing are to guide a bar in the field and the lathe set up had two sleeve bearings just to control the chatter or vibrations in the bar. Keep in mind there are many different ways to do the same type of machine operations as in line boring. ;{)-----

[@watahyahknow]

cool idea it inspired me to make sumtin with those bearings to bore out the 6 cilinderbushes out of an aluminium jaguar engine and bore the alumimium for the new oversize bushings wat im thinking of is making full engine length plates that bolt intoo the headbolts on the top and the carterbolts / mainbearingbolts in the bottom so it will allways align the bearings for the boringbar to the borespacing on this engine specificly i use a regulair cross table with the electric drive to move the block toward the electric motor (drillpress layed on its side driving through a hole the foot of the drillpress ?) driving the bar quite some distance away from the crosstable it prolly take time to reset the bar for every cilinder but it should work

[@hydrator1]

that was some damn fine work I have a little job like that myself coming up you gave me some good ideas thanks for all your hard thinking........

[@operator41001]

Great video's, Lots of information keep em coming

[@manuelmonroy3267]

Keith I finally found the round tool bit sleeve at MSC The tech there did not know what I was talking about. Wonder if he is family ??? Thanks for sharing By the way I am boring some cast iron for a dividing head kit I baught from a UK outfit. You are probably familiar with it. Thanks again I really enjoy all your videos and keep saying that you do some settups that really blow my mind Manny

[@KeithFenner]

Ya, about a .0005 to .0015 clearance, those flange bearings amost allways slip on cold roll materials...

[@sammorgan31]

Could also use round hss tool blanks and grind your own tools to fit round hole. Old broken tap and endmill shanks work too. or just O-1 Drill rod that you heat with a torch and harden yourself.

[@troaduk2]

Hello Kieth, I have bored and faced both ends of casting for a vertical head. I plan to bore a bearing seat one side, turn the casing upside down and do the other. I am using opposing tapper rollers so I need the seats dead square. Question is... what is the likelihood the bearing seats will be square. Or does the whole job have to be done in one hit? Thanks Dave :)

[@donaldkiefer9718]

HI KEITH can you tell me where you got boring bar tool holder insert i liked your design would love to get specs so i could make my own thanks Don

[@firstmoonboots]

Git'R'done with what you got! Done a fair bit myself. I call the star drive "geneva movement". Google "tsc carbide tool bit" - these are square shank bits meant for boring with the hole in the bar center. Take a look at the weird angles (they work like no other brazed carbide bit can for the purpose). Also available in tsa (square, 0 degree lead), trc, tre (round bit, 30 & 45 lead). These are also superior for lathe & boring head work. Good luck!

[@erichope1103]

WOW ! You really drag some big bugs into your shop from time to time.

[@DavidParker-cf2km]

Keith, please tell us where you get the round/square inserts that hold the cutting tool. I don't have a broach, so this is a very necessary part for me to make a boring bar. Sincerely, David Parker

[@1ginner1]

David, with all due respect to Keith, you don't actually need the square insert. If you are using round tools, just mill a flat on the top of the tool and you tightening stud will line it up square.

[@kenschubert4697]

I found them in the MSC catalog, you can probably find them from other sources

[@aweldingservices666]

brilliant work mate thank you for the help!

[@Bookerb2004]

This was very interesting Keith 👍

[@DL5FS]

hi keith I apologize for disturbing you with my questions! but i dont understand the thing with the line boring bearings, you show us a video with a long pipe that you runing thru the lathe and it should be to nearly 99% in angle from side to side how does this work with the flexibel bearing ?? thank you for the answer i stll like all of you videos !!!

[@benclancy8005]

Where do you get this adjustable inserts?

[@kmcwhq]

Keith, Didn't see in the comments if anyone asked.......what do you call those "round to square" sleeves, and where did you get them?? thanks

[@josephnovakjr8198]

Great job!!

[@luked237]

Great video 🙏

[@9traktor]

Fine equipment - keep on!

[@briangoetz65]

Very nice, good job

[@firstmoonboots]

After finding pt1 & viewing I should add I have never had any problems with the ts & tr style geometries self feeding so I've never used a bar pre-load (spring thing). For the CAD thing in pt1... I used to say "crayon" LOL!

[@Kalkaekie]

Very cool !

[@gregg4164]

Ha, I love it. Put her to work.

[@PATSICK]

If you look at the you tube video, "line boring a large excavator bucket"; you can pause the vid. and see a square tool running in an ordinary drilled round hole; this is completely satisfactory.

[@ponkkaa]

Nothing boring about this video. :)

[@tedsykora1858]

that had to be one of the most difficult things to try and explain. didn't do too bad

[@marceloramone1]

muito bom ,belo trabalho.

[@mrdrivermechanictv4213]

Awesome

[@donaldkiefer9718]

lol didn't read question before mine

[@kmcwhq]

Oh wait.....I found it down below!

[@PATSICK]

The square hole insert thing is just a waste of time; I've made several boring bars; a 3/8th. Chinese brazed carbide lathe tool fits in a 1/2 drilled round hole. the Set screws coming in a ninety degrees to the tool keep it located. It never even occured to me to mess around trying to made a square hole, it's obviously a waste of time. I have also tapped the reverse end of the hole to obtain calibrate drive depth for the bit; this is also obvious.

[@TSKseattle]

Wow, John, glad everything's so obvious to you. Sorry it such a waste of your time. Where's your hundreds of videos showing your decades of experience. These videos are enjoyed by thousands of people who have never seen this stuff done before.
