Thanks Paul. I was only able to like your last video but unable to comment on that lovely precision drill. Been having difficulties recently. Bet you'll have it running to perfection very soon. Cheers Neil
Glad to see your mind blowing presentation…...….it is my pleasure to stay beside you as your permanent follower……..always be creative and keep posting such fantastic stuff……..have a prosperous future ahead…….
Gday Neil, this information will definitely help someone, my first lathe had bronze bearings and they worked well considering the age of the lathe, I could never part off even after adjusting them but I put that down to the ways being absolutely rooted, thanks for sharing mate and take care in the heat, Cheers
Danny! I had to share this. What a great design, bearings with integrated threads . I guess this was conceived just before precision roller bearings became readily available. Thanks so much for watching and commenting. Cheers Neil
Thanks. Nicely done. That will be helpful. My Harrison manual has an interesting spindle preload setting using a string and a fish scale. I imagine an old engineer decided simple is good enough. You are likely right, the spindle may have taken a set. Could shift again for the better and maybe need a tweak. If you have one, an infrared temp meter may be handy to qualify the preload over time.
All things being equal, the simplest solution is usually the best. My definition of Occam's Razor. I don't have an infrared temp meter so I'll continue with the usual temperature monitoring. Touch until you burn and them spit and sizzle method 🤣🤣🤣🤣🤣
Hello, new to your channel and brilliant find for me as I recently purchased the exact same lathe as my first one. Needs a bit of work to get it back to a good state but looking forward to it.
Hi Jo !! If you are stuck with anything, give me a shout. Always glad to help out where I can. I will make a video showing the spindle removal soon. Cheers Neil
Nice video mate -- as usual, and I'm sure it will be of interest to lots of people, not just those fortunate enough to own a similar lathe. Rather than remake all the buggered collars, why not do a refurb on them? Take them off and re-drill the holes and make a spanner to fit? Just a suggestion. I will be glad when this fine weather breaks and we can resume our morning chats, I'm missing you 😀 😀 😀
Hi mate! I was considering plugging and re-drilling them, but as you are so well aware, I have very little confidence in the abilities of the lathe. She's old and should be retired by right but I'll keep her going. Even though the collars are unsightly, they still work and once I get the lathe operational I will have a better idea if I should invest money into it that i dont currently have🤣🤣 To rainy days and long phone calls. Cheers Twato....
Hi Bradley. No, I'm afraid I dont know the bearing numbers. It was 1942 and details are very limited. When I'm well enough, I'll take a trip to the workshop and pop a bearing out. I will look for numbers or identifying Mark's and post my findings. Cheers Neil
@@NellsMechanicalManCave Thanks Neil, I hope you feel better soon. If all goes well I'll be picking one of these beasts up tomorrow for about 150 pounds, seller says it just has to go and the headstock is a little wobbly, not sure about the bedways though. Is there anything you can tell me to look out for / test before I buy it? Thanks once again.
@NellsMechanicalManCave Hi Niel, sorry for the second message but do you know where those axis wheels you have came from? I can see they're quite nice and have obvious divisions for somewhat accurate tool movement but the one I'm looking at has generic handles and no divisions? Thanks once again
Hi Ben. This hopefully has adjusted the bearings to some degree. I will have to wait until its run for a while and then re-adjust before realizing its effectiveness. Did comment on your tig welder video but it wouldn't post. Scratch start welders are a pain. Cheers Neil
Hi Neil. Looks like you've got that as tight as you would want to go. Is there enough meat in the casting to fit taper roller bearings? It would make a big difference if you could fit some.
Hi Olly. The casting is too narrow and I dont think I'd gain much by doing it. It only goes to 550rpm so TRBs would be wasted on it. The best I could do is swap the entire headstock for one from the 1950s that way they are fitted and would do 850rpm. Good thought though.
Neil, An interesting video on adjusting these bronze bearings. Is it in your plans at some point to remake all of the buggered up collars? If they were in my lathe it would drive me nuts. 👍
Hi Jim, great to hear from you! At this moment in time I don't think I have the skill set to remake the collars. Even though I spent a great deal of time in engineering, it was in heavy maintenance and I'm still learning precision machining. I've only ever cut one single point thread which was external and never tried internal cutting due to the lathes limitations. As I learn more from watching people like you and others like Joe Pie, I gain a better understanding of lathe work. That's why I've undertaken the task of making this lathe more usable. To me it used to be a tool that turns round things into smaller round things, but I now see it has so much greater potential. At some point I'll take the Spindle out and then rework or renew the collars, but for now I want to see if I've improved things or caused more problems. Thanks so much for watching and commenting, cheers Neil
Thank you Paul 😊 I try my best to keep videos short and entertaining whilst sharing an idea. Glad you liked it and thank you for the sub ! Cheers Neil 👍🏻
Hi Neil, I'm a little embarrassed that it's taken a day for this to happen, but a very considered and insightful comment about this video has popped into my head..... THAT VIDEO WAS PANTS! hehe, just kidding 😜
Thanks Rick ! This video might be out there for years, but one day it might help someone. That's why I do this 😁 Thanks for watching and commenting Rick, really appreciated. Cheers Neil.
Thank you Neil for an interesting look at how your lathe bearings are set up. It will be interesting to see a follow up. 👏👏👍😎 Andrew (Melting in his workshop 🥵)
Thanks Andrew. I hope it will help someone one day. Yes hot in the workshop. Got to have a good supply of surplus redundant clean underwear to mop the brow 🤣🤣🤣
