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
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
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.
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
A 6mm tapped hole in the end of the shaft & a cup hook in the drill . I have a few rods with different threads that have a ring in the ends for the cup hook . 👍
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.
Really looking forward to getting the Churchill grinder running , but that will be some time yet . Cheers 👍 Lol , ah it's Glen . Did not catch on at first !
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
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!
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.
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.
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.
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...
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.
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 🤣🤣🤣🤣
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
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'.
This time , it was a quick clean with emery . Sometimes a centre drill or grinding stone is used . Most grinding machines are graduated in tenths & smaller or the metric equivalent . 1 thou on a grinder is a country mile . 👍
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.
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
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
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?
I did not have enough clearance with the drive dog . Stalling is no problem as the tool post grinder can only remove small amounts . The down side is that with extra tailstock pressure , tail stock adjustments may be required . As was the case . 👍
I was too restricted for room , so pressure between centres was the best way . It does not take much to drive when grinding with a tool post grinder . 👍
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? 😉
Thanks . Lol , the thing on the rafters is a 1957 farm implement ! Can not remember the wheel rpm , something around 4000 rpm . The wheels are rated for 5000 & i know it's well under that . Lol , the tractor has 2 wheels & a sticky out thing ! 👍
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
I have one . But from memory , it goes off the boil too quick and requires frequent dressing & results in slight wheel hop type marks on the finish . There are only 3 types available that are not a special order . The one i used in the video , the 9A60 & a silicon carbide one from Abrasiflex . Other suppliers do not keep bugger all in stock here so i have learned to get by with the limited options . Need to get the Churchill cylindrical grinder up & running ! 👍
Hi again. With the 9A wheel or most white wheels for this application dress the wheel face so that only 1/4 to 1/3 of the width touches the work. With too many grains touching there is a lot of puch back. BC
@@swanvalleymachineshop My grandfather was a blacksmith on plows buggies wooden wagons etc and he never either but I have seen knife makers argue about it ... Your heavy steels shouldn't suffer crystalization shocks or warping.
I know you have done this hardening thing a few times. Does this process end up with just a case harden or through hardened? Does the oven temper it or just stress relieve ? Do the gear teeth need grinding or not? Cheers Mate.
Pretty well through hardened . The low temperature temper helps prevent embittlement cracking but the part can not fall below 100 C from quenching to tempering . No need to grind the teeth , they were good . I can not do that process anyway . Cheers 👍
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.
Lol , i watch them as well ! I bet they have a list of back & foot injuries a mile long ! I often wonder , how many You Tube machinist's could survive in those environments with no mod con's ! 👍
I refuse to watch their videos. I figure if they have to sit barefoot on a dirt floor cross legged to work on machine parts, because they are too stupid to build a bench to work at and a stool to sit on them there’s little likelihood I’m going to learn anything worth knowing from watching the videos. 🙄🤷♂️😜😂
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
I can’t believe your shop is getting full! This is the best machinist channel on CZcams.
It's full alright , just ally ways ! Thanks 👍
For sure.
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
Quenching has always fascinated me. But the use of the faceplate in background was super cool. It's dangerous but fun with Max.
Thanks Matty . Lol , the tractor is very basic . I will try & get a picture ! 👍
The face plate was to act as a driving plate , but was too cramped for room . It also protects the cam lock spindle nose . 👍
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

I would never do it with heat treated parts , you could start a crack . 👍
@@swanvalleymachineshopadditionally you damage the heat treatment.
Doing that to a hardened carbon steel part is a recipe for disaster.
