Thread: This came with Myford ML7 - anyone tell me about it?
26/04/2017 09:14:59

Paul Gander:

I will scan the two articles and email them to you. It looks from Ady 1's post and yours that at least two of these were made.

I had forgotten that LHS edited The Model Mechanic and wonder what, if any, was the relationship with other like publications of the 1950s.

Robbo:

I have just turned up the two issues of The Model Mechanic in which Sparey described his gearbox.

Paul is welcome to contact me if he is interested in seeing these.

Thread: Ticket Clippers??

For the record, a proper ticket punch makes a hole, not a notch.

They were invented by the Victorians for a job creation scheme, giving employment to street urchins who would sweep the chads off the floor of coaches etc. at the end of the day.

Neil

I suppose they didn't want the chads hanging around?

These seem very similar:

Thread: What Did You Do Today (2017)
23/04/2017 18:53:17

I was inspired by Darren Conway's setup for balancing a pulley in MEW 254 to check the balance of my CBN wheel. I was surprised when I bought it described as balanced to see how many holes had been drilled to achieve this. Here's a picture of my own setup showing the wheel actually settled at the point of the drillings:

And here's the result of adding 5 gms of Blutack to the opposite side:

Now to calculate the size of hole apparently needed!

Thread: Lathe chuck removal

Mike Poole:

Points taken; the link on lathes.co.uk relates to a South Bend lathe where the tool grips the spindle rather than anything keyed to it.

If Chuck is really stuck this helps

**LINK**

There are to many broken back gears out there.

Thanks for this link to a useful-looking tool.

I don't recall Tony Griffiths' website article on this subject being mentioned here - I only chanced on it myself just now - but it is well worth reading and contains a link to a similar tool.

Tony doesn't mention Sparey but he does sell his book!

Graham Long:

Not the answer to your question but, given the premium asked for the steadies, why not make your own?

Thread: Lathe Chuck Attachment Methods.
19/04/2017 10:26:44

There is a useful discussion of this topic in Cliff Bower's Book of the Lathe and his conclusion is worth quoting:

"The possibility of making special attachments for the spindle nose should be borne in mind by the lathe purchaser. If it is expected that many of these will be required, the screwed or flanged types are preferable. If standard work-holders are to be used, which is highly probable, and it is expected that these will have to be changed frequently, the tapered type of spindle nose offers advantages because of speed with which attachments can be mounted and removed."

This is an old book from 1955 and I understand the Camlock came into use after this date.

There is another video here:

The presenter suggests that the Superfly "could even be used on a Bridgeport" but how many amateur shops have one of those?

It's a shame my name was spelt incorrectly though. At least my name was correct on the front cover

Yes, I see they gave you an E for effort! I think it was right in the contents section so two out of three...

John Rudd:

I would say your stable pretty much covers the field with the exception of the (I think) obsolescent long taper spindle nose L0, etc.

My Willson slantbed has this feature and, apart from the extra weight of the much heavier chucks, the need to clean the taper and lock ring and tighten the latter with a large C spanner makes for much longer changeover times.

Andrew Johnston:

I have no experience of Camlock which, however, I associate with larger, more expensive, modern lathes. For many, I think the real comparison will be with the flanged spigot which I understand is used by some modern popular machines (again, I have no experience of these).

Thanks for your article in MEW 254.

SillyOldDuffer:

By way of comment on some of your bullet points:

  • The lathe certainly can be reversed; eg, I regularly do so on the Myford to wind a tap or die off the work. I agree that care is needed
  • Normally there will be a register behind the thread which is what provides the truth; the thread doesn't need to be a very good fit
  • Shock load, etc - agreed

To Michael Gilligan's suggestion of economy I would add the factor of tradition.

An advantage of the threaded mandrel is the ease of changing chucks.

Thread: This is worth a look

Thanks to herbert punter and peak4.

I watched this in some awe of the manual skills involved. Interesting that they also supply handles with these rasps - and beautiful ones at that.

No 21 WPS is from 1991.

I think that the author, David Lammas, also wrote an article in MEW.

PS There is some information on the Arc website.

Won't square tube distort when one of its sides is cut off?

Nick Hulme:

Thanks for reminding me of this thread. The reason for my resorting to PM now was that I envisaged sharing with the OP an article submitted for publication in the magazine and wanted to avoid any question of conflict with MTM's house rules.
