I've been wondering about how I could go about line boring on the lathe and how would a clever fella go about securing the work to the cross slide - nice solution! Colour me very impressed!
G'day Max, You and I both know that in the case of getting a bit of vibration we can wrap our bar with a piece of lead which will deaden any chattering. Just a tip for any of your viewers new to this type of work. Best wishes , Mal.
Max that was a wonderful fix--enjoyed every minute of it--being careful pays enormously and I am into my 70th year and still have not mastered the inside calipers..regards E
Max, Your fixture plat and jacks gave me some ideas. When all someone has is a lathe it can do almost anything if one is clever enough. Having the fixture on hand and two of those to do at one time either made you a good deal more money or saved your customer a bundle of cash.
👍very good machining video.Witness mark is the perfect word to use for the tiny bit that did not clean up, it bears witness the parts strength was not compromise.
Hello Max. I did a similar job like this about 15 years ago, except I had two sets of bores that had to be a precise distance apart. I set up on my cross slide and the plan was to use the travel of the cross slide to accurately space the bores apart. Unfortunately the travel on my cross slide was about 1/2" too short. I ended up mounting a rotary table to my cross slide and then setting the part up on it. After boring one set of holes I rotated the table 180 degrees and was able to bore the second set of holes. It took a while to set up but I had quite a few of them to do so it was worth it. It's those jobs that keep it interesting. Ken
Great fix. Much enjoyed seeing the process of repair/salvage of a part that's probably not available for months if at all, and no doubt saved the owner a bunch of $$$. Thx for the vid.
Gday Max, that’s a brilliant result, I’ve started using inside dividers lately here and getting mixed results, it’s certainly a feel I have to master, I really hope you continue to do more videos like this, This is a good way for me to learn more, thanks mate, cheers
Great to see the springbows in use, big improvement on the friction type, I was amazed being taught how to tap them to open or close to take a comparison. Great method to learn "feel " on the comparison to an external micrometer, for some jobs, we booked plug gauges from the stores, always a hand on the job to assert temperature, especially brasses and copper. Again, great setup, thanks for sharing.
G'day Max, great series, thanks. We don't see spring calipers used very often except for those Pakistan videos, well done. 40 years ago I had a feel for them, just getting the apex right and then the right amount of drag without deflecting the legs, hmm definitely need to practice that again if I had to do it. Cheers Peter
Hello Max, Enjoyable viewing, thank you... I try and use calipers (internal and external) to get myself close to the target measurement and then switch to something a bit more accurate... See you on the next one. Take care. Paul,,
With no doubts, you are a better machinist than me, but I would had never clamp anything placing the clamp on a hollow area, the clamp had to be above a solid area , in your case I would had used two claps , one on each on the same sides, as well the one on the opposite side, as long they would compress on solid without twisting the cast, otherwise as soon you remove the tension it would sprung back to it's original shape and the line bore would be gone, unless the casting could be stress relived in position....I have been around too. Never the less, the machining is superb, Thank you.
In most cases , yes that's right . Clamp on a solid area , but not always possible with out a great deal of fixturing . You have to look at the part & have knowledge of how it is used to determine what you can & can not get away with with out adding unnecessary cost to the job . 👍
Hi from Brisbane. Josh Topper recently put up a clip where he used a shaper/planer gauge to set the height of the boring tool. It sets the height above the boring bar accurately.
I've been wanting to make a fixture for my lathe like this one you have. Curious what size socket heads you used to bolt the cross member's to the carriage. Great video, thanks for taking the time to make it
Gday Max is it worth showing to others how to shape the point on calipers to get a better measurement I learnt that in 1996 when apprentice they are still a good tool no batteries and do imperial or metric no switches thanks for your vids old school still useful
In this case i will use either 4140 or 38mnvs6 & harden them myself . If there was time for them to be sent away for proper furnace controlled heat treatment , i would use EN36A . 👍
I always hated those sorts of jobs. Too much time spent on setups. If I had my own manual shop I would probably turn those jobs away because it would take me hours to set up just for 20 minutes of machining lol!
I look at it as later on down the track , the fixtures will be used again . That is when you re coupe . Swings & Roundabouts ! I did not have to make anything for this job as i had already made it for a previous ! 👍
@@swanvalleymachineshop What about milling a flat on each side of the shaft and using an adjustable parallel on each side? Put a radius on the face that contacts the OD, expand the parallels until you make contact, mic to heart's content.
I’m such a neophyte sometimes. When you first put the tool bit into the bar I wondered how you will control the depth of cut. You then just simply pulled it out enough to hopefully clean up the low spot. Seems reasonable. Then it didn’t clean up. Hmmmm I wondered, how do you carefully add to the depth of cut? It’s not like a boring head on a mill where you just drive the lead screw a few thousands. 🤦♂️🤦♂️🤦♂️. Of course you idiot. Max simply pulls out a indicator on a stand and measures it. 🤦♂️🤦♂️🤦♂️ Thanks Max for opening my eyes to obvious simple measuring solutions. I feel like such an idiot 😂🤣😂
Wow, just amazing. Never seen lineboaring done on a lathe before.
Thanks . 👍

I have this sneaky feeling that Max knows what he,s doing !.
Shhhh !!! 👍
Experience can save us alot of money in replacement parts. Beautiful work Max!
Thanks 👍
Max, Not “boring” at all. Very nice to know how it’s done. Thank you for sharing your many years of experience. Cheers, Will
Thanks 👍
This is one of the least boring boring vids ever!
Cheers 👍
The time spent to make the fixture in the past really paid off this time around. Hope the weather is being kind for a little work on the new shop.
The weather should be ok , giving a bit of rain . 👍
I liked this one, I’ve never done a line bore before. Very helpful. Thanks much 😅
No worries 👍
Great result Max, tailstock chuck performed well. "The witness" = signature of a skilled and well trained machinist! Well done. Cheers, Jon
Thanks Jon . That chuck see's a fair bit of use now . 👍
G'day Max, You and I both know that in the case of getting a bit of vibration we can wrap our bar with a piece of lead which will deaden any chattering. Just a tip for any of your viewers new to this type of work. Best wishes , Mal.

Thanks 👍
You mean liquid sunshine.
Max that was a wonderful fix--enjoyed every minute of it--being careful pays enormously and I am into my 70th year and still have not mastered the inside calipers..regards E
Thanks . Yes , there is a bit of a knack to using them . 👍
Nice work Max, always appreciated when you can save a part from the scrap heap, enjoyed, cheers mate!
Thanks 👍
Good one Max! 👍😁👍 Love that line bore fixturing!
Cheers Chris 👍

Thanks . I try to make fixtures like that to fit multiple jobs . 👍
That was really interesting, Max. Thanks for showing the technique. You have given me some other ideas.
Cheers Rob . 👍

Very cool project max, I've done a excavator knuckle on my sebastian lathe, the setup takes forever, great video, keep'um coming.
Cheers 👍
Such a long shaft and no chatter. That's quite amazing.
Thanks . When it was wanting too , that's when i had my hand on the bar to prevent it . That's why we don't wear rings in the shop ! 👍

Cheers Matty . The spring callipers are not too bad , the non spring type are on another level ! I should do a video on how to use them ! 👍

Yes , you have to learn the feel ! The fixed ones are a bit harder to learn . 👍
Enjoyed watching Max, this made a change from the usual machining methods practiced on the lathe. Tony

Nice work Max. I bet you are itching to get the HBM up and running. I can't wait for my knee to heal so I can get back into the shop.
You are not wrong there Graham ! 👍
A simple job to you with your skills an experience, thanks for sharing.
Cheers 👍
Hi Max. Another good job done. I wonder how many of your viewers know where Porirua is? Ian Langley New Zealand
That would be interesting ! 👍
very very good job max,,the old school forever
Thanks . 👍
that is a good result max !
cheers, ben.
Thanks . 👍
Bloody youtube, only just caught this mate, time a cuppa and a catch up
Better late than never !!! 👍👍👍
Hi Max really great work on boring the part, do you have any video on making the fixture plate and the bar? Thanks again Cheers
Thanks . No , the bar & plates i made before my you tube days . 👍
Hi from Brisbane. Josh Topper recently put up a clip where he used a shaper/planer gauge to set the height of the boring tool. It sets the height above the boring bar accurately.
Yes ,that would work if you have the room . I have only ever used the indicator onto the tool & find it's quick & accurate .👍
Crafty. Very crafty. 👍
Thanks 👍
Great results max ,good presentasi
Thanks . 👍
Thanks Max! Very useful info.
Cheers Sam . 👍
Nice one! Once you have the new shop up and running, I imagine the HBM will replace the lathe line boring.
The HBM and the big Stanko mill will . How's the bionic joint going ! 👍
@@swanvalleymachineshop Shoulder is doing great 😊. Going to send you an email in a bit.

The only shape difference i know is to slightly flatten out the curves on the end , to give better access around a boring bar . 👍
Nice job Max, enjoy the long weekend.
Thanks . Gunfire breakfast after the Dawn Service tomorrow . 👍
Gosh I need to make a Tailstock Chuck.
Do it ! Using it can make setting a steady rest a 2 second piece of piss with long material ! 👍
Thanks for showiing what you can do if you wount to thanks
Cheers 👍
Max, do you plan to insert bushings to bring the bores back to nominal shaft diameter?
Yes , they will be over size hardened bushes . 👍
Enjoyed your video, what sort of material do you use for the o/s bushings?
In this case i will use either 4140 or 38mnvs6 & harden them myself . If there was time for them to be sent away for proper furnace controlled heat treatment , i would use EN36A . 👍
What are those rollers by the ram spares down on the floor???? Look like massive rollers out of a roller bearing????
Lol , they are 740 Cat brake accumulators that i was going to use for rollers for something , but came up with a better plan ! 👍
Pretty sweet . Is there a video on the making of the bar ?
No , that was before my You Tube days ! The square tool holes were broached in the Bridgeport . 👍

Maybe you could make something akin to an ID mic that could go into one of the other positions for a cutter?
They are already out there . The tool holes in the bar have to be on centre with the bar for them to work . My ones are off set . 👍
@@swanvalleymachineshop What about milling a flat on each side of the shaft and using an adjustable parallel on each side? Put a radius on the face that contacts the OD, expand the parallels until you make contact, mic to heart's content.
