Adcock & Shipley Mill Leadscrew Repair

[@andrewdolinskiatcarpathian]

Well done Clive for the intelligent solution to what must have been such annoying problem. In doing so we get to see your side project making the slitting saw arbor. Excellent all round. 👏👏👍😀

[@Workshopfriend]

Thank you, Andrew. I wasn't sure whether to include the making of the abour in this video - but then it would have been too short on its own.

[@constantinehatzis2807]

Very satisfying solution to the problem. I can imagine the person who took out the lead screw years ago discarded the split collar thinking it was broken. I recently made a couple of low profile slitting saw arbours. Very handy items.

[@Workshopfriend]

Yes, it could look broken. I think you are right - it had been left like this for a long time. I need to make more arbours of different sizes.

I always enjoy your videos with your careful and calm approach to problems. Thanks

[@Workshopfriend]

Thanks for the feedback, Richard. So long as careful and calm doesn't morph into slow and boring!

[@thomasstover6272]

Thanks for sharing! That is a beautiful old machine!

[@Workshopfriend]

Thanks, Thomas.

[@jeffbarrett1787]

Always interesting enjoyed watching thanks for sharing Clive.

[@Workshopfriend]

Glad you enjoyed it, Jeff.

Very nice work mister. Good fix.

[@Workshopfriend]

Thanks, RustyInventions! Satisfying to complete jobs like this.

Another superb video, Thanks Clive. The surplus to requirements component you removed from the lead screw looked like a hydraulic bonded seal.

[@Workshopfriend]

Thanks, Carl. I didn't know that is what it was - just that it was plated.

[@carlwilson1772]

@Workshopfriend Not sure either but it looked like it had an elastomeric part around the periphery of the id.

[@Workshopfriend]

I had a closer look. There is one on the inner dia.

[@carlwilson1772]

@Workshopfriend Possibly someone thought the elastomer would provide some friction to somehow grip the dial.

[@philhermetic]

Excellent solution!

[@Workshopfriend]

Thanks, Phil!

Easy fix Clive, pity about the eccentric hole in the slitting saw, the rear tool post is an ideal mounting point for the Mag base.

[@Workshopfriend]

Thanks, Willem. Yes, getting my money's worth from the rear parting tool!

[@paulbyerlee2529]

It surprised me when I first came across Jacobs chucks that use a ring which is deliberately broken into two halves. I know this is a little bit of a different scenario but could definitely understand the part being discarded because of a lack of understanding for it's function.

[@Workshopfriend]

Yes, could be left out of a rebuild! I suspect this had been missing for years.

[@waikanaebeach]

I have exactly the same on my ES2 A&S mill. I don’t have a slitting saw so I marked it off with a centre finder and used the thinnest hacksaw blade to cut the ring.. bit clean up, all good.

[@Workshopfriend]

Yours, was a much more sensible approach! To justify mine, however, I wanted to make an arbour anyway.

[@stevewilliams2498]

My Adcock and shipley mill keeps slackening off by itself. Or as Joe would say it "unloosens" I will take advantage of your groundwork and see if I can work out the problem. The other 2 dials Knee and Y are fine. Strange, we both have a problem with the same dial. My machine is considerably larger .. ISO 40 spindle but externally the dials look identical.

[@Workshopfriend]

I would like to add an X axis table lock but haven't seriously looked into that yet. Mine also has an ISO 40 spindle.
