Hi Dave
Cheers for that. Something therapeutic about filing aluminium! And yes I do like to keep the lathe clean.

Mike
I uploaded everything the same as usual. Same format etc. Does it work if you go to youtube direct instead of via the forum?

Glad it's working today - computers eh!?

Glad you are enjoying the videos although I've got a thumbs down on the latest one already. I guess you can't please everyone. It would be good to know why so I can improve things where possible but I don't think YouTube ask users for a reason?

Yes but it might have been clicked by mistake, easy to do

Don't beat yourself up over it- probably someone that does not even know what it is. The videos are perfect - detailed, informative, light-hearted where needed and very clear.

I didn't want to say anything as you are doing a cracking job on your build, however if i had to bore a pulley i would have set it up in a 4 Jaw with 4 short pieces of silver steel inserted into the belt slots and clocked on the OD of the pins then it's spot on with the newly bored hole. however if you don't have a 4 Jaw this isn't an option.

Hi Mike
I welcome suggestions on other ways to do things so please do mention them. I've only had the lathe a year or so and still lots to learn. I do have a 4 jaw chuck and it takes a bit of time to swap over (retaining nuts are a bit fiddly to access) but I like your idea. Pity I've just bored out the ones for the X axis so they are all done! Next time though . . .

Episode 13 is now ready - machining the ball screws and installing them on the bed.

I spotted the "this old tony" bit with the 4 jaw

nice as always.

Does the grubscrew for your pulley locate on the actual ballscrew ?
Looked like it might be fixing into your extension.
Regards
Mike.
Thanks for the update
