Thread: New Lathe replacement for Myford
10/08/2021 13:51:26
Posted by Trevor Drabble on 09/08/2021 00:25:16:

Also , Lathes UK have a Myford 254S for £3500.

Crikey, I had better get mine advertised for sale then, it will be a lot less than that! laugh

Whatever material you settle on, don't try copper yet, unless you have experience of machining cheddar cheese! laugh

Thread: Strange effect when turning
25/05/2021 11:02:15

Did you use the toolslide to turn it?

If so, very quick check:

Turn it again, using the toolslide, check result.

Then again turn it in the same way, but lock the toolslide, and use the saddle to advance the cut.

Check both results and compare.

As it is happening over such a short length, my guess would be the toolslide gibs.

Perhaps someone could re-purpose a Bridgeport as a candle holder?

A bilgeport is far too flimsy to upcycle into a candle holder.

RIP Sir John!

As soon as that was mentioned I thought of John too! smiley

Thread: Myford spindle rectification or replacement
21/01/2021 10:37:31
Posted by Peter Turvey on 21/01/2021 10:23:15:

There is minimal runout on the taper inside the spindle.

This then suggests to me, as stated in my previous post, a careful check for damage, or foreign objects such as swarf, inside the spindle taper.

There may be no runout on the taper at the spindle nose, but an issue inside the spindle nose taper.

Given that it is hardened, it would be difficult to damage the spindle internal taper, but very easy to get swarf, for example, inside it.

Also, has anything been done to the lathe leading up to the issues you report - has it been moved, dismantled in any way disturbing the spindle, etc?

If the spindle taper is clean and undamaged, and you carry out a bearing check as suggested by Hopper, then I suggest there is no issue as such, other than age of the lathe, and tolerance in chucks etc.

Minimum projection of collet chucks and work beyond the nose/chuck is important, as these will only amplify any runout.

That didn't appear to be a test bar in the chuck, but a piece of mild steel round bar, which could be like a banana.

Have you checked runout on the inside of the spindle? All of your videos check runout with something attached to the spindle. Is the morse taper on the inside of the spindle scrupulously clean, and undamaged?

Have you checked runout with a decent ground MT test bar in the spindle?

Not really interested in re-building an MGB

Peter G. Shaw

Nor me. If I wanted to read articles about rebuilding cars, I would buy 'Practical Classics' or something like that.

As the magazine title is 'Model Engineers' Workshop', I would prefer to read articles more linked to model engineers' workshops wink

When I snuff it, I don't expect my executors to go through all my log-in details and let everyone know I've exchanged metal-pushing for daisy-pushing. I'll just quietly fade away and no one will miss me, either.

Amen to that! laugh

Thread: Fitting Chuck Jaws
27/02/2020 17:05:36

To insert jaws of a self centring chuck, this is an easy way.

All jaws should be removed.

Go to empty jaw slot 1. Turn the key until you see the start of the scroll thread cross the slot.

Back off slightly, push jaw 1 in, lightly hold it in, turn the key and engage the scroll thread in jaw 1. As soon as it engages, stop, go to empty slot 2.

Repeat jaw 1 instructions for jaw 2 and then 3.

Thread: tipped tooling
23/02/2020 09:24:04

Centre height wrong?

Too much tool holder overhang?

Wrong insert tip radius?

Wrong speeds and feeds?

 

EDIT - hopper posted whilst I was typing! wink

If it works and is safe it isn't bad practice wink

If you have the right tool tip for the circumstances there isn't a problem.

It's a time saver too!

Thread: The Workshop Progress Thread 2020
04/02/2020 09:47:11

What am I doing in the workshop at the moment? Not a lot!

I moved house in November, no garage at the new house, my workshop contents (largely, not all of it) are currently sitting in a 20' shipping container on the drive!

Planning application currently in for a garage/carport/workshop (the workshop is 6x6 m internal), if all goes well it should be built and the workshop back up and running by around the end of July.

Very frustrating, particularly when something I want is, of course, at the back of the container, and I can't get to it!

I've had a PM confirming I'm a baddy.

Good grief! Is nothing sacrosanct? I'd put you in the always worth reading category, even if I don't always agree with you. smile

You will almost certainly need a C curve MCB to run it, it will probably trip out a B curve on startup.

That appears to be a Komet boring bar.
