Hi max, I have spent the last 3 plus weeks, watching from your very first video to your last. Looking forward to more videos as they appear. Your workmanship is just amazing. From the kiwi.
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.
Nice one Max. Got my Bruce Whitham Gettr Out Gear Pitch Gauge right here in my treasured tool section. That is gonna be the finest lathe of its breed when you are done. If only the factory had shown it so much care and thoughtful work.
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.
Gday Max, interesting how they have used both metric and imperial on the same shaft and you definitely have the same luck as me, buy the cutter to find out it’s the wrong one, I think I’ll look into the inserts for roughing, great video mate, cheers
Hi Max, I generally use 17/4 PH for shafts of unknown origin, Its great quality and tough as a spinsters crack. Looking forward to the rest of the restoration. Best wishes, Mal.
I never paid much attention to the different incerts. Thanks for taking some of the mystery out of thier use. Kimber P S I have a lot to learn about machining
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!
Mixed imperial and metric reminds me of the late 70's in the UK, cable sleeves were measured in imperial for length, but the bore was always metric. Crazy times LOL
@@chrisstephens6673 On the subject of bearings, the automotive industry is notorious for "special" bearings, to ensure you buy spares from their dealers.

Hey , no worries Graham . There was a set of those bloody glove clips in my walkway today on the concrete floor at work , thought of you straight away . 👍
As cool as a cucumber maxy checks revolving centre for heat & run out. Measure twice cut once. Been caught out by that usually at home. Work could mean being shown the door. Great chuck tip.
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.
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 . 👍
@@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

@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.
Great Vid Max, I see your sporting a Mattys Workshop hat. Love his channel too. I haven't seen any new content on his channel for a while now. Do you know if he is doing ok? Thanks, Mike
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...
Max how much metal do you have to dig out of your hands in a week man I love your videos some of these other guys needs to be watching your channel they could learn some things
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?
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 . 👍
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.
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 . 👍
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. Cheers from NC/USA
G'day Max. Excellent job, shaft turned out really well. Wondering what the other meshing gear is like, whether you will have to make another one. Is there a metric equivalent to the 10 pitch ? I have a new small set of metric gear cutters, & same set of Bruce's gear templates, will check it out in the morning. Just never know.

Nothing like a mix ! 👍
A mix of inch and metric on a machine can be confusing, but on the same part it certainly keeps you on your toes!
With Whitworth threads in the mix as well ! 👍
Mixed systems are not that unusual, bearings are frequently metric sizes being cheaper than low volume production imp ones.
@@chrisstephens6673 On the subject of bearings, the automotive industry is notorious for "special" bearings, to ensure you buy spares from their dealers.
@@russelldold4827 true enough, also for things like screws. Douglas motorcycles use unique threads so you had to buy genuine spares.

Hi Max,
What do you think the purpose of the relief section on the small diameter is ?
Oil passage to the bearing maybe ?
Just sits in clearance . Nothing runs near it & i think it would be cheaper to manufacture as it's not a tight tolerance .
I guess not only is it 10DP but it looks like its 14.5deg PA as opposed to the 20deg of the module cutter.
Still investigating that one . 👍
