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

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

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.

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'.
@swanvalleymachineshop7 ай бұрын
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 . 👍

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

@RicktheRecorder7 ай бұрын
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?
@swanvalleymachineshop7 ай бұрын
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 . 👍

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 ! 👍

Hi Max. On the harder work try a 9A 60 wheel. White alox will perform better. BC
@swanvalleymachineshop7 ай бұрын
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 ! 👍
