I can’t believe your shop is getting full! This is the best machinist channel on KZfaq.

Gday Max, the new pinion gear worked out absolutely spot on, the further jobs look very interesting, that tractor is pretty sophisticated by the sounds of it mate🤔🤣, cheers

Always an absolute delight watching your working methods Max, working with that old machinery, getting Stefan like precision, just amazing. The next project looks interesting too, tractor eh?😊 cheers from the UK, Dave

You make it look easy Max. Well done once again. 👍🏻 Those are some interesting looking tractor parts my friend 😊

Thanks for the vid Max. Camera work nice, clear and good focus control. Keep it up pls!

The shaft turned out really well. I did a similar hardening technique when trying to make a small gauge for an aerospace company. They were warping like crazy until I held it in my drill press and rotated it slowly while heating it. I even got so fancy as to have the cup of quenching oil on the table and dunked it in by feeding the quill down while still rotating. I was amazed at how much it reduced the distortion. By the way, I liked the subtle swipe. (You don't need $10,000 worth of Starrett granite but I do think you need to level it to within .00025"/mile). Ken

Thx for a Great vid Max.

Nice clean heat treatment, even presence of mind to reposition the camera, great idea of vertical rotating part, i did see your R8 arbour videos, old fire extinguisher makes a great quench tank. Great job again Max.

Max, with regards to the “Tractor parts” I didn’t know you were a subcontractor for The Australian Armour & Artillery Museum. 😉👍🏴󠁧󠁢󠁳󠁣󠁴󠁿

Thanks Max, I learn more from every video. I have 2 questions: 1) How did you suspend the shaft from the Mag Drill? Did you tap the center hole? 2) Found your answer to #2. Why no drive dog when grinding the shaft. I've done a couple of small heat treat jobs in my hobby shop; a one off metric transfer punch, and a threaded stem for a lantern toolpost. I also used my toaster oven to temper them. Ken

Wow another great video, thanks Max, From kiwi land.

Love that toolpost grinder work...beauty!

Looking good! Another project checked off the list. 👍

Awesome stuff as always!! Like the proper (CAT ) bolt securing the grinder too ! Best regards Paul

Love the work, Max. Cheers.

Great vid dude congrats on the good finished gear with all those steps done right. Flame spray build up will be cool to see I've never heard of that before.

very good job max..thanks for your time my friend

great video series mate, you make grinding look easy, bet you cant wait to have the cylindrical grinder up and running !

Great work again Max. now time to finish the JFMT lathe and make first chips on it to see how it performs. The spray welding project looks interesting as well. Cheers

Thanks Max. Have a good one 👍🇦🇺

Great Job Max. I enjoyed learning about every step required to achieve these impeccable results. Cheers 👍👍😎👍👍

Nice job. ...and look at that shop !!

The least amount of Pig into the part…….uh can you translate into North American for a Yank learning Aussie? It’s a process to understand y’all sometimes 😂. Appreciate your generosity in sharing your knowledge of the “ old school “ way of building machine tool parts. Thanks Mate!

Thank you for sharing, Max.

Enjoyed…nice build

Nice work Max, reminded me of my first acquaintance with a lathe and grinder. An older mechanic used to put the grinder at an angle and dress the wheel to be parallel, Anyhow, it turned out nice and thanks for awakening some ancient memories.

Thx Max always good to see what your working on. Hope we get to see the tractor turret assembly in action

another good video max ! thanks for sharing. cheers ben.

Superb workmanship Max Cheers Chris

As near as I can tell, the mathematicians got really stuck years ago and came up with imaginary numbers to help them out with some problem solving. Now I can see no objection to using imaginary letters and words to solve crossword puzzles, or you, as a excellent machinist and artist to having an imaginary Starrrett inspection bench underneath that cloth. Easy-peasy. Just be careful to not drop anything heavy on it. Cheers and another great video, thanks Max.

Excellent video, incredible results. I'm very interested to check out the tool post grinder videos you mentioned. I liked the trick of angling the tool post so that it would advance at only a fraction of the normal infeed.

Excellent result Max It’s great to see a master at work 👍👍

Well done Max

Good work!

Great video max, came out great..

Looking forward to seeing the apron on the JFMT back in action. Is that the last of the refurbishments for the JFMT lathe, or are there others? Those unobtainium 'tractor' parts look interesting 🤣🤣🤣🤣

Really nice !

Nicely done my friend

Fascinating and instructive - as always. When you said " just clean up the centres", is this just a polish with a bit of emery cloth, or is it more involved?. I'm curious as the grinding world seems to be in the realms of 'tenths'.

Very outstanding job all around. Couldn't ask for any better. . Good Job.

Beatifull job !!

Beautiful results Max, I've really enjoyed and learned from your TP grinding episodes 👍I need to venture down that path fairly soon. Practice parts first... Thanks for bringing us along... Cheers....ATB...

Once again very nice and accurate work......Thanks for sharing

Very informative. Thanks & Good onya

Hi Max, Top slide angle 5.8 degs, every thou on top slide dia is a tenths in feed cut. Steve

It’s important to get the piece into the tempering oven immediately after removing it from the hardening process. Sometimes people wait a couple of minutes, and that’s too much.

Hi Max, you can remove warpage in a shaft with an oxy acetylene torch and no hammering or forcing. heating quickly very small spots to red and quench and mist with water. this is done between v-blocks and using a dial indicator. there are videos out there to show the process. Rich

Love this video as of all

Great grinding work! Really enjoyed the process. Thanks!

Nice job Max. I thought you have a cylindrical grinder, when is that seeing the light of day.

hey mate, feel free to hit me up next time you have any heat treating to do. I've got a Paragon heat treating oven. more than welcome to pop one street over and use it if I'm around. I got it to heat treat some W302 as no shop would take there gear to the temp i needed.

G'day Max. Excellent video with the Hardened gear. Did you use engine oil to quench the Hot Gear, or water. The machining turned out really well. Should run well when you do a refit

Very nice I love your videos. I do t get to comment much because I watch you on tv on roku but I have watched every video. What steel did you use for that? I’m not sure if you mentioned that. I wanna play with some heat treating. I haven’t done it yet. I’d love to see more of that insanely monstrous mill you have! Thanks for the videos

Max, you started off shewing the component driven by a dog to the catchplate, but the actual grinding was done without any visible means of rotation other than axial pressure on the live centre. Don't you need to be careful about stalling the rotation and getting an uneven grind, and/or overloading the live centre?

Is that a knucklehead up in the rafters in your intro? That's a hella nice surface finish for what looks like quite a coarse wheel? What rpm is it spinning? Don't know why exactly but I'm really pleased it came out so well. (even though your 12,000 miles away and outcome doesn't affect me, must be getting soft in my old age 😁) Is the 'tractor' kinda 'tracked vehicle' restoration with a large 'sticky out thing' on turntable? 😉

Nice vid Max. Where can you get one of the pointers that was snapped onto your micrometer barrel? Thanks

Interesting video. Thanks. I didn’t see any drive dogs on the shaft while turning. Is the pressure from the tail stock enough from when grinding ?

👍

Great video, the grinding wheel GW2160 A46MV ?

That sounds like a rather unique tractor someone is restoring there! Can I assume if you had a surface grinder you would have used that with the part spinning between centres on the surface grinder table? Just curious how the results or time taken for the job would fire (a question from a person without access currently to any metal lathe.milling machines). Thanks again Max Mark

Grant what way oil do you use for your lathes. Do you run that same oil for your cross slide. Another great production like always.

Hi Max. On the harder work try a 9A 60 wheel. White alox will perform better. BC

With all the trickling coolant, i wonder how many times machinists use the urinal in a day, hahaha.

Do you have to do anything to the teeth? Nice job!

Hi Max, nice job, when are you going to profile grind the gear teeth? Joking of course! Watched the Pakistanis molest a large DSG lathe the other day, felt sorry for the old girl. Interestingly they had 2 Webster & Bennet vertical borers same as the ones we had at the refinery.

I suppose if you want to attractor you need smoothly running rollers. The old ones look far too knarly.

I think it's time for me to find a toolpost grinder...

Max, do you preheat your quenching fluid before you start the heat of the part?

Hi Max, Was just wondering if the teeth were still running true as the shaft deformed. I have a nasty picture of you trying to re-mill those teeth at 50+ rockwell. lol

It looks as if you are in big trouble, it is nearing December 25 and you do not have your wife’s Christmas gift ready for wrapping and delivery.
