Watching this makes me feel I’m the new lad in the shop. a kindly old hand is showing me how to do the job the way it needs to be done. He is not above reminding me I have a lot to learn. Thanks for taking the time to share the accumulated wisdom.
Love your channel Max. You not only tell us what needs to be done, but you also take us step by step on the set up, then checking, then rechecking. Even the tooling needed. Great channel.
Shrinkage on a cold day - yeah we can all suffer from that. 😆 Still - nice tools, even shorty. 👍 Quite the task getting that undercut in there - that was really great. Cheers!
Good one Max, they came out well. A good operator always makes difficult things look easy. Nice when a bandsaw balls up works. That sort of thing doesn’t happen often enough.
G'day Max. Now that is a Stupendous bit of tool making & machining to get the tolerance & fitment required. Most of all it went into position & fitted like a Glove, not a sock 😮😅😊 Well Done. Keep up the Excellent Machining Tutorials
Hi Max, Many moons ago I made a set of what we in the UK called cow mouth toolbars, ( just a piece of bar with a slot cut in the face), for jobs just like the undercut here. The beauty of that, was that all you had to make was a series of small undercutting tools ( for internal O ring grooves). I still have them in my toolbox. These days Sandvik, Iscar et al, have a range with tips to suit any internal work like this. But it gladdens my heart to see skills like yours doing it the old fashioned way, after all in a jobbing shop, its hard to justify going to the big tool suppliers and laying out a small fortune for something that you wont use all that often. Keep up the good work mate, Best wishes, Mal.
Rell done Max, nice to see that you are willing to make anything necessary , it is too easy just to buy this stuff if you have tons of cash available. Cheers mate!
Really enjoy your Channel and it's people like you that gave me the confidence to go back into a profession I truly love. Thank you for producing the videos you do! When boring jaws, I always touch on the inside of the chuck bore and as I know the size, I put that into my readout or on my dials and then bore the chuck jaws to exactly the size I want. I know you don't use a DRO, but could be done on the dials.
Hi Max, Olga will be happy to be fed with extra tooling without swapping pull studs. My machinery supplier south of the river said I was working in the dark ages without a DRO, fitted an Accurite DRO to my BP clone back in 95, it was like someone switched on the light.
Well done Max, you'll never look back, no more fiddling with backlash, reading dials and setting up dial gauges. Our eyes are not getting any younger, with a DRO display less prone to make a mistake.
Great video Max. I know that machining the bayonet undercuts in the lathe is probably the most efficient way of doing the job but it occurs to me that it would have been a great opportunity to try out the new boring and facing head.
Nice bit of tool making/grinding Max. Cool Mist 77 is my go to coolant fluid for the mist sprayer. (I suppose you could use any coolant, I never have) I like the Noga Mini cool sprayer unit better than the Cool Mist brand sprayer. It sure makes a difference in tool life when using HSS end mills. Poor old Bridgey could use a DRO when you get some spare change eh? As always.... you never disappoint.👍
Happy days Max, 6.00am here, and as usual I'm watching as I prepare for my day ahead. One thing I didn't understand was how the feeler gauge helped setup the part square? Here's to a great one buddy, thanks for sharing 🎉
I am a no expert - am a self taught machinist but this had me thinking too. I think how it works goes as follows. For the first machined part Max used a finger indicator to get the slot parallel to the bed. The chamfer cutter is set up in the centre of the slot, width wise and length wise. For the 2nd part, Max moves the table horizontally so that the cutter is nearer the end of the slot. Max has first determined the width of the slot, then subtracts the thickness of the shaft of the cutter, then the remaining measurement is divided by two. That remaining dimension is the thickness that Max selects with his feeler gauges. The theory is that if the slot in the job is parallel to the bed, when the cutter is further down the slot (ie away from the mid point of the length of the slot), then the feeler gauge should fit equally down both sides of the cutter. If the slot is not parallel to the bed, then the gap from the edge of the slot to the cutter varies side to side. Max then rotates the part til the feeler gauge slides smoothly down both sides. Took me some time to work out what/how Max was doing it. Max might have a much simpler way of explaining it. Max also might be gracious enough to show us all, in a future video, a better explanation of how this works. Overall, Max is a very smart bloke. He had me stumped as to how he was going to relive the interior of the parts. I have learnt heaps from him.
Cheers Bob . It's a never ending learning curve in this game , no matter how long you have been at it ! But yes , just equalise the gap to the cutter at the end of the slot with feeler gauges . It is accurate enough for a guide in chamfer . 👍
4140 pre hard TGP . I thought about a chip breaker or grinding a back rake , but then i thought i would save that in case the tool was struggling . Cheers 👍
I’m not surprised at the difference. I’ve had odd results too. Cutting up one side and down the other resulting in a lopsided slot or center shoulder. Thinking about it makes sense. Conventional cuts tend to dig in while climb tends to push away. Also sometimes climb gives a better finish and sometimes conventional does. Coolent usually gives a better finish and sometimes not. I’m sure some company has figured out the math for all of this.
Max, you ought to mark the lugs/slots with a paint marker or similar to avoid the (slight?) aggravation when you try to insert the arbors (new & old) 180° out of "proper" alignment.
Thanks for sharing your knowledge with us. As a newcomer to machining as a hobby, I find that things take so long to complete especially setting up a job, checking clearances, work holding, etc. How long did it take to make these? Thanks again for sharing your thought process's.
An interesting and informative video, as always. Thanks. What kind of oil are you using in your mist coolant? Normal oil for flood coolant or a special one for mist coolant ?
The tool is unable to face the whole width of the rear inner face if the bore is not relieved . It just saves a lot of dicking around that would not achieve anything . 👍
Awesome video, as usual. I like how you show us how to work without a DRO, I'd like one, but reality it will probably never happen, and watching you get round not having one, inspires me not to buy one
a total underrated channel. very nice

Another really cool video. The undercutting operation was very interesting and the parts came out great.
Thanks Rob . I am getting a lot of use from those tool steel blanks ! Cheers 👍
Nice to see you're closer to getting Olga horizontal 🤣 And the runt of the litter became 'Top Dog'. All-in-all, I'd call that a perfect win.

No worries 👍
Awesome work Max. The Runt proved its worth in the end!! Cheers
Thanks Randy . 👍
Well done Max, excellent outcome. That should reduce the complaints when it’s time to slip Olga a new tool. 😅

I was a bit restricted for room for that style of tool . But , i agree . The special tools for that purpose are expensive . Cheers 👍
G'day Max, from Lincolnshire UK 🇬🇧,
Cheers 👍
Nice work and a good demo of the tooling issue and solution. I always learn something from your videos. Thanks.
No worries 👍
Liked it ! and what a nice job in your really nice shop !!
Thanks 👍
Very enjoyable series of videos Max.
Thanks 👍
Gidday Max. Love the chat the other day.
No worries Graham . Cheers 👍
Nice builds !!!!

Keep these great videos coming I actually watched this one twice...
Thanks 👍
That was a lot of work, but now it's done and a relief.
Big relief ! 👍

Haven't had any issues with my cheap spray mist unit but it doesn't have to work for a living like Keiths. Hope it stays that way.
We shall see how it goes ! 👍
Thx for the vid. Nice work.
Cheers 👍
I was wondering how you would handle the undercut. Well done!
Cheers 👍
Very good, forgot what material you used but looks soft enough. Think I would have ground a light chip breaker in the tool but yours did the job well.
4140 pre hard TGP . I thought about a chip breaker or grinding a back rake , but then i thought i would save that in case the tool was struggling . Cheers 👍
@@swanvalleymachineshop We use a lot of en grade this was EN19 and M45 thread for scale.
th-cam.com/users/shorts5H60thNUEmk?feature=share
Lovely job again Max. Are you going to harden, temper and blue them as well?
No , they have enough hardness to them with the 4140 pre hard material i used . I would like to see them blackened though . 👍
Nice 👍🍻
Cheers 👍

It varies with material as well . This was 4140 pre hard , so it was just a case of try it & see how it reacted due to the cut depth . Cheers 👍
@@swanvalleymachineshop I just bought a 13” by 3.5” round chunk of 4140 HT (RC45). I can’t wait to start on that.
Max, you ought to mark the lugs/slots with a paint marker or similar to avoid the (slight?) aggravation when you try to insert the arbors (new & old) 180° out of "proper" alignment.

I did not keep track of time due to filming . I would allow about 2 hrs each for a quantity of 10 if i was not filming . 👍
An interesting and informative video, as always. Thanks.
What kind of oil are you using in your mist coolant? Normal oil for flood coolant or a special one for mist coolant ?
Just flood coolant . 👍
Hi Max, on the last operation, been trying to imagine but unable to come up with any purpose of the center hole relief, now I'm curious.
The tool is unable to face the whole width of the rear inner face if the bore is not relieved . It just saves a lot of dicking around that would not achieve anything . 👍
My favorite kind of projects, the ones done by others.. 😅
Lol , Cheers 👍
Will Olga like being turned into a cnc. May have issues.
Lol , she already has semi auto functions ! 👍
Suprised at the difference in width of the slot between the climb cut and conventional milling.
Just the way the cutters deflect from one direction to the other . Cheers 👍
Send them out for nitriding possibly
That would be the go . Cheers 👍
Had to dash off to the loo at 5.40
Lol , Cheers 👍
How can I know the master jaw I have a Chinese grizzly 10x40 much like the one u are using
Is your chuck or jaws marked? #1 is usually referred to as the master jaw.
If it's not marked , just use the most accurate & repeatable pinion when checked with something round in the chuck . 👍
Awesome video, as usual. I like how you show us how to work without a DRO, I'd like one, but reality it will probably never happen, and watching you get round not having one, inspires me not to buy one
Thanks . 👍
Good morning

Excellent work! Thanks for the look "easy" Max.
No worries 👍
