With no doubt, this video is exactly why I love this channel. It pisses me off that your channel has such a small subscriber base. I subscribed before you had 3 thousand. I have been watching for almost 3 years.,,,, I see you bending over backward to give us great camera angles & the minute details. I want youtube to get off their ass & put your channel up front. No matter what Max, I want to say thank you. I have learned so much watching you. I really wish I could stand around a camp fire & drink a cold beer with you. 👍 Cheers my friend.

Gotta love machine builders, very rare operator and instructions manuals are updated during manufacture, I know, I write manuals , no system in place to update engineering revisions. I purchased a DBNR tool based on your recommendation a while back, great roughing tool, and using unused corners on the CNMG inserts. Nice job Max, thanks for sharing.

[@dermotkelly2289]

Nice job mate. When I was in the industry I worked as a maintenance fitter but sometimes I would not use a lathe or milling machine for some time and one day they wanted a new pinion shaft made and I hadn't cut a gear since I was an apprentice and I completely forgot about how to do it ! It took me about 3 hours to machine the shaft and around 10 hours to cut the gears lol. I spent most of the time reading books about it.

[@radardoug]

I have a Precision Matthews lathe that looks remarkably similar to yours (probably the same Chinese foundry) and I have adopted your technique of parting off in reverse with the parting tool upside down in the tool holder with great success. Gravity seems to drop the chip curl out of the cut rather than having it curl up on top of the cutter and weld into the cut. There's no problems with the part trying to climb up over the cutter too. Great trip!

Hi Max, I have the 24 edition Machinery's Handbook, copyright 1992. Yours I am guessing is 1977 The rapid travel on the saddle will put a lot more wear on the rack and pinion which are prone to dirt and chips. Wondering if a Bronze sacrificial pinion might be the way to go, hate to have to replace the rack.

[@swanvalleymachineshop]

Not sure what year that edition was printed . It was my Late Fathers . I wonder if the new ones are all metric , if so i might get a newer one . I also think the rapids would create a bit of extra wear , mixed with the crap that gets in there . The one on the DSG seems to be cast iron & with almost no wear . 👍

[@hmw-ms3tx]

@@swanvalleymachineshop I've got the 25th edition (large print edition, which is a lot handier now than when I got it) and it has both imperial and metric. I would assume later editions are both systems as well. Ken

I have the 33rd. It’s both. I imagine they will be for some decades yet.

[@TheAyrCaveShop]

G'day Max, Great video...thanks for the information and knowledge shared prior to diving into the turning...really pulls it all together. Cutter preference and info is very helpful as well...I and probably other home gamers really need help wading through all the cutter options. I've certainly picked up several that just don't work on home sized machines. That was some interesting material, was it a ball screw or some type of jacking screw ? Enjoyed... ATB...Cheers...

[@swanvalleymachineshop]

Thanks Dean . As far as i know , the shaft was a puller rod . It's really good high tensile material , i think similar to an EN25. 👍

[@JW-qd4ig]

@swanvalleymachineshop Good day Max, did you happen to mention what steel/material you chose as replacement? I have watched a couple gear shaft machining videos you created. However, i do not believe i caught the type of material (maybe you said it and i missed it). Thanks fella for your skills and very easy to listen to and watch videos.

[@swanvalleymachineshop]

The material has high tensile steel that i did a hardening test on . Cheers 👍

[@stevewilliams2498]

Hi Max, What do you think the purpose of the relief section on the small diameter is ? Oil passage to the bearing maybe ?

[@swanvalleymachineshop]

Just sits in clearance . Nothing runs near it & i think it would be cheaper to manufacture as it's not a tight tolerance .

[@jasonhull5712]

My Clausing Metosa has that special blend (metric and imperial) makes for a more interesting experience. 😊

[@swanvalleymachineshop]

It sure does ! 👍

[@MyLilMule]

I have seen you in the past grind parts that you have heat treated to get them to the correct size. I am curious how you handle the gear teeth. I ask because I hope to be getting a gear made for my horizontal mill's vertical head, but it won't be heat treated. If it was heat treated, would it have to be ground to shape or what's the typical process?

[@swanvalleymachineshop]

The gear will be made to size before heat treatment . Only the bearing journals will be machined after & fingers crossed it will stay reasonably straight after heat treatment . The gear can be cleaned up with a wire buff & scotch bright . 👍

[@ThePottingShedWorkshop]

I guess not only is it 10DP but it looks like its 14.5deg PA as opposed to the 20deg of the module cutter.

[@swanvalleymachineshop]

Still investigating that one . 👍

[@swanvalleymachineshop]

Thanks . I think he must have had enough of making video's . 👍

[@melgross]

It’s interesting that on a lot of British stuff, you find metric and inch (being I’m from the USA I don’t say Imperial) mixed on parts all the time. I’ve found shafts that are metric with inch screws, as well as a lot of other equipment and parts. I find it annoying. I’d much rather have it one way or the other. I wonder why that, Chinese I think, lathe would have these parts in inch. Possibly for a mainly inch oriented market? As far as that shaft. It looks like a ball screw. I would expect that to be hardened, at least the surface, yet it didn’t look that way when you were working it. I also like that circular gear gauge. I’ve got the usual sets. This is nice.

[@swanvalleymachineshop]

Thanks . I think the shaft was a type of puller rod from a concrete yard , something to do with pre stressed concrete & concrete moulds . I suspected they would be good material . 👍

[@hmw-ms3tx]

Hello Max. "It's imperial on the lengths and metric on the diameters". Sounds very, very Canadian. I'm looking forward to seeing you cut the gear teeth. Not many videos around of that. Ken

@@hmw-ms3tx I think it's just the way things go . I have a few like that as well . The way to get the most views is to have no clue what you are doing , make some sort of fuk'd up centre punch or similar but take a really good thumbnail shot !!! There are quite a few that cheat the system & use view generators . Try & tell me channels like Inheritance machining does not do that !!! 👍

@@swanvalleymachineshop I'd never heard of Inheritance Machining before. I went and had a look and yes he does get a lot of views for someone who started 18 months ago. He must trigger the algorithm somehow. I think I did that once. I had one video "Roughing on my large lathe" that had been on youtube for about a year and had around 1,000 views. All of a sudden in about a week it got 250,000 views. My next closest video has about 23,000 views and most of my videos barely break 1,000. That video must have got picked up by the algorithm and recommended to alot of people. Some guys seem to have the touch. Having said that I much prefer videos where the content is good and at the level that I work at. That's why I like your videos as I always seem to learn a new trick from you with each one. Ken

[@HaxbyShed]

I learned a lot Max. Highlighted some big gaps in my knowledge (being just a late-coming hobbyist). Probably your method to identify the gear pitch was the most interesting for me. It's a whole area I need to research. For DP there is then pressure angle - did you just go for the middle ? (20PA?) Cheers

[@swanvalleymachineshop]

And there is adjusted profile ! That is what i am dealing with . Forget pressure angle , that gets complicated with a non standard gear . I will go through it in another video soon . Hey , how is your solar going . We had our system installed a while back on the shop . Cheers . 👍

[@HaxbyShed]

@@swanvalleymachineshop Hi Max, right I will be watching for the gear form lesson, that will be very useful. Up to now it was on my long range radar (general awareness) but not so relevant, but since I've got the mill now it's only a matter of time before I want to cut a gear or two. I'm going to do an update on the solar late/end August. I'm very pleased with it but it's really taken until July (3 months) for it to settle down with one event or another affecting output. I've just about got to a point where I can get some confidence in the payback calculation. With a battery there are just so many variables in play, it's hard to model theoretically on a spreadsheet.

When repairing machine tools, check very carefully the threads and gears used. For instance, my Taiwanese milling machine is metric.... except for the British Standard Whitworth fasteners used in several places. My Taiwanese lathe is all metric.... except for the Unified National threads used on all the control levers. Be wary of old machines, especially pre-WW2. Metric fasteners weren't standardized universally. Germany, France, and England each had their own standards. There are plenty of odd ball imperial threads to keep an eye out for, especially pre-WW1.
