It's a youtube short fizzy it's designed to be watched on a phone verticalJust because the borer is vertical doesn't mean the video has to be
I guessed as much. Just like tiktok.
Ruins it on a laptop or desktop though.
You should do a longer video looks very interesting!

I use a Chrome extension to block them on my laptop, saves me getting tempted to click a stupid thumbnail.
Brilliant just been having a look. Loads of proper videos
I see you doing work on a js540. Mine will operate one way but then refuses to self feed the other. Turning the lever by hand doesn't work either but sometimes it does if you catch it right. Any ideas?

Either the hydraulic system needs looking at or you've not depressed the knock off pad on the right hand side and the table is going back to park position.Brilliant just been having a look. Loads of proper videos

Or the table has been lifted at some point in its life and bent the hydraulic rams.
I think it's down to that knock off pad. How is it supposed to work? Basically I can initiate the action manually but it won't repeate. Keeps resetting itself.

Never thought I’d get a 5ft Meddings pillar drill column on the little Boxford!
The three jaw chuck kept dropping it in slightly hair-raising fashion, so ended up bolting the base flange to a face plate and clocking in.
Nothing fancy, just a run down with the grinder wire wheel and emery cloth to tidy up. Mainly rust and hardened grease. Finished up with a coat of machine wax, which is less sticky.

That's called walking, the part is walking out of the chuck.
Either you haven't got the part perfectly centred in the steady or the steady is not true with the axis of rotation.

Yes, exactly what was happening. It was trying to be a universal joint, and very hard to set up single-handed. Very little jaw contact.
Thought for a bit, and realised that a perfect custom chuck (base flange) was lying on the bench looking at me.
@Guineafowl nice little boxford!

I found 3 small bearings in a drawer today which I forgot I had (the bearings, not the drawer).
Then I had a bit of a brainwave and decided to use them for ball bearing fingers for the South Bend steady rest.
So I cut of some bits of 12x50 flat bar and milled them square and to size.
Nice sliding fit in the steady and no wiggle.
Tomorrow I will drill some holes, mill some slots and turn some pins.

Something i've not had to do before.
Machine a worn out flange for a taper lock. 1108-28.
Went fine, if working to the fenner document, diameter at the large end should be 38.2-38.28mm.
I made this 38.2 but it still sits somewhat proud of the flange.
Won't matter for this application however but something i'd like to clarify for future use.

I have seen taperlock bushes sit proud in the past, and I always just put it down to tolerance issues.
They still work, so I've never really looked into why.
However, this did remind me of a post by the late John Stevenson, which you might like if you find yourself needing to regularly machine hubs for taper locks - https://bbs.homeshopmachinist.net/forum/general/51004-tapered-bushing
