You removed the hardness of the taper and the bearing races...they were hardened for a reason...simply spinning it on the lathe and sanding/scuffing/cleaning with scotch-brite would have been ample for cleanup...now it will not last as the bearings will chew up the races...
Unfortunately for me it didn't fit my lathe. I had to turn the tail to change from Morse MT4 as it was from the factory, to MT3 to fit. The bearings were removed and did not suffer during warm up and the tail is still extremely hard for my little hobby lathe. Thank you for your comment!
@@JIMMY916 I missed the part about having to change the MT4 to a MT3...I guess then if you had to make it fit and the hardened shank was too hard to cut even with carbide tooling then it was a good mod and you saved the live center from the scrap bin...so I retract my previous statement and change to a thumbs up...(forgive us armchair machinists...we jump to conclusions too easily) subbed...waiting to see more
I know that the audience that looks at this kind of content is a very demanding audience ( most are former machinists ) or they are good connoisseurs. The fact that you fast-forwarded the video is my fault because I didn't manage to make you watch the whole video. I would be lying if I said that I don't want to receive positive comments, but the ”negative” ones also make me understand some things. And anyway, I consider all of you my friends and you are no exception. Even more so after the last comment.
Jimmy never mind the assholes you did a good job with what you have. Not everyone understands things aren't perfect when they have a room full of tools and nothing has been bodged before. Those are the ones that throw away things like that center
I know I can't please everyone with my videos. Some like it, some don't. My goal is to present the things I was doing anyway, even if I wasn't filming myself. The fantastic thing I got thanks to UA-cam is the nice feeling I get when I get comments like this from people like you. Thats makes me happy and I thank you for that.
Great modification from MT4 to a 3 Jimmy! You might consider making yourself a toolpost grinder with both stone and diamond bits. You could then regrind that live centre to a new undamaged point.
True what you say. Unfortunately, we are sometimes a bit wasteful and easily give up objects that can still be used, which is definitely not good. Thank you for watching and for your comment sir !
Did you re harden the taper off camera? I'm not sure the process of case hardening but if you were able to anneal it you should have the right equipment for it.
The reason why I had to heat it in the fire was to be able to turn it. From MT4 made by the factory to MT3 as my lathe uses. After being heated and cooled slowly, it's hardness remained very high ( I barely managed to turn it ). So re harden is not necessary for me. My hobby and small lathe has no way of ever failing this live center. Thank you very much for your comment ! P.S. My camera is never off :))
They wew already butchered and I don't think I could open them with a pin spanner because of the rust. I will definitely not need to go there again and if I still have to, I will rectify those holes and use a pin spanner to make everyone happy. Thank your for watching
So often one sees assemblies which need a C spanner or a pin spanner being chiselled round with a steel drift, usually by Pakistani machinists. If you are too lazy to make the correct tool, it is but the work of a few minutes to make an aluminium drift to do the job. This will cause no damage whatever. You are but an amateur bodger rather than an engineer if you don't have soft jaws for your vice and aluminium drifts to use for jobs for which you don't have the correct tools.
If the two holes were intact I would have built a C spanner. But are you sure he could undo it being so rusty stuck ? If I didn't succed, what alternative did I have? I didn't film how long it took until it started spinning. Anyway the guy who repaired before me long time ago used the same method as me for the opening, so the holes were broken anyway and useful. Soft jaws for what? I use a textile glove to protect the vice jaws not the live center extremely hard. And anyway it was going to be turned and converted from MT4 to MT3. Where did I go wrong? Thank you for your comment !
Kind of harsh on a hobbyist aren't you? Why are people like you even in existence. Even with my bad eyesight I could tell the holes for the spanner were buggered up. This holier than thou crap should stay in your little mind. He is not a full time machinist and you are an ass.
Love the video and the effort to give an old tool a new life … away from the trash heap.
Thank you very much sir !

You gave me a good idea. Coming soon :))
Very nice work sir
Thank you Mr. Rusty !
Nice project❤
Thank you very much! I'm happy that you liked it.
Nice rebuild. Any time you can rebuild and save something from the trash is a good project...

Love all process
Thank you very much !
Make a pin spanner instead of butchering up the holes. So many things wrong here.
