Mini-Lathe woes
Twinsquirrel:
Disaster, well maybe not a disaster but certainly very annoying!!
I've managed to strip 3 teeth from the main gears on my mini lathe.
You'll notice the lack of any kind of grease inside the headstock, I know that a lot of people may say that those GRP gears are self lubricating but I have my doubts about having no form of grease in a high torque environment like this?
I wasn't even doing any heavy work, just a light facing cut on some 50mm aluminium roundbar, no 2mm interupted cuts on stainless or anything like that :(
To be honest, I never really wanted to see inside the headstock on this lathe as I'm not at all confident that I can regain any accuracy when I reassemble it.
The problem I have now is sourcing a new gear, I havent spoken to my supplier yet though.... Also the spindle seems to be "locitited" into the bearings and I have no idea how to remove the spindle from the casting without damaging either the bearings or the spindle.....Has anyone here ever done this on a mini?
:( :(
Still, it's all good fun,
David

David,
I did that to mine very early on, I was parting 20mm brass at the time.
Don't panic, I have a pulling kit for this very lathe that i had to import from the US. You are welcome to borrow it.
Just get a couple of metal gears, they are not expensive. You might want to change the bearings to tapers at the same time as they have to come out anyway. Well at least one does.
I have the part No's if you have a local bearing supplier, might be cheaper that way.
It's not that difficult a job....don't panic..... :thumbup:

David,
What part of the country are you from?
If you are within striking distance from me, and you get the parts and puller together. I don't mind doing it for you while you wait. I can't do it as a leave it job because my workspace now is getting very small and haven't got the necessary storage space any more. I could then reset the head for you after the job is done.

I'm in darkest Wiltshire so about a 4 hour drive from you. Shame it's just that little bit too far, although I am coming up to Harrogate for the show on the friday (I have been informed that we have a wedding to go to on the Saturday :( ) so if I haven't got it sorted by then I may take you up on you very kind offer, thank you again.

Again I'm overwhelmed, do you have a pic of the puller? I have a number of different pullers available to me which could possibly be adapted to suit, If not a loan of your puller would be very greatly apprieciated. It would be sensible to change the bearings as well while I'm at it so if you do have the part numbers to hand that would be great too.

Thanks for that Jason, I hadn't realised that it was so common for these to shear but I am glad to see that it's not an expensive fix.... Just a bit of a B*ll-ache..
Thanks again all,
David
