Thread: Picador Grinding Wheel Flanges
15/09/2019 15:04:16

Extract from the relevant HSE advice

Safety in the use of abrasive wheels Page 18 of 53 Health and Safety Executive

Material for flanges

Flanges should be made from good-quality mild steel such as that specified in BS 970: Part 1: 19966 or another material with sufficient strength and rigidity to resist undue deflection when the flanges are tightened on the wheel. In view of its low tensile strength and the risks of cracks developing in service, grey cast iron cannot be regarded as safe for the flanges of abrasive wheels. For small abrasive wheels (for example straight wheels on small bench grinders) flanges of non-ferrous alloys have been used successfully.

Sorry about the mess of fonts!

I wonder whether, with a suitable slot, they would be heavy enough to make a stand for a mobile phone?

If really stuck it may be possible to drive through a long cold chisel from the side and use it as a lever.

As a long term user I was interested in this.

The motor seems new ie not the Parvalux which used to be supplied. I couldn't see anything about speed control which seems a shame.

I would like to see more information on the website before buying the £61 "card".

Many thanks. I can now see the video and will watch it later.

In the meantime, where I went wrong it seems is that having spotted the redundant period between "youtu" and "be" I tried to search just on the tail of the URL. However, I now find that Firefox and Duck Duck Go between them find the video despite the typos.

Did you mean the Hemingway Sawing and Filing Attachment (I couldn't see a die filer on their website)?

Sorry I can't help directly but Hemingways will surely tell you if the attachment will fit your lathe.

Thanks for that link Martin - it clearly shows how a tool in a rear tool post or upside down in the normal one 'springs' away from work as against 'jamming' when set up in the normal way better than just using the words as I did. A picture says a thousand words and a youtube video can often be even clearer!!

It is a shame that the computer simulation shows a tool so far above the centre though, as that makes the problem bigger than in real life.

Boiled engine fittings...surprise devil ? What gas mark ?

George.

Oh, come on, has everybody lost their sense of humour, I for one thought it was funny but perhaps that says more about me!

Doug

When I read the OP from a relative newcomer I was tempted to ask "boiled or steamed?" but refrained for fear of causing offence. He seems, from the commentary on his video - nice lathes! - to be from the US, and is a welcome visitor.

As always, communication would be easier and friendlier if there were a profile to refer to.

The comments about nylon remind me that some time ago I helped a sailing friend to overhaul a cutlass bearing. I don't remember the details of this but note a suggestion elsewhere that the bearing surface of the plastic material involved is fluted.

Is it a maximum of 35, 36 or 40? Or just the editorial discretion?

Not sure what the tilde (~) means in this context.

I’m sure we all have one and mine regards to my favourite Mitutoyo micrometer. It only fits in the box when the anvils are nearly touching. And it’s one of those old Mitutoyo’s with the mechanical numerical wheels so every time I have to store it I worry about the wear and tear to that rather intricate bit of kit.

Why didn’t they design the box so that the thing would fit with the thimble “extended”?

Mark

They did:

But, so far as I know, M&W didn't!

Holbrook precision lathes seem to have been eclipsed by their chunky brethren over the decades

Universities and cinemas appear to have been major customers

Holbrook article

Thanks for this interesting article. It was a relief to learn that the toddler shown as part of the staff in 1872 was apparently not actually employed in the works!

This was from a series of article and I wonder whether the Willson ("We make nowt but lathes" concern was covered?

Thread: Myford ML7 - Size of Mandrel Through Drilling?

My 1964(?) S7 SK 66266 will just pass 0.620" from the tail for most of its length.

This is the major diameter of my J A Radford stop bar. His was 0.621" and was "perfectly free in the mandrel except for the end nearest the chuck which was reduced to 0.580" ".

Fascinating stuff! For some reason it reminds me that Gamages had an establishment there, too.

Thread: Lathe Identifier

Liam Hutson:

I think that this sort of upgrade is usually a shop-made effort calling for some straight forward turning and dividing. GHT's MEs Workshop Manual may give you some ideas about how to go about it. You would need to identify the leadscrew pitch of course and decide whether to go for radial or diametral marking ie whether a given depth of cut is off the radius or diameter of the work. From your photos it looks as though one problem would be the location of a witness mark.

I see from the link to Tony's website that on some of these lathes "cross and top slide were fitted with, for the time, generously dimensioned micrometer dials" and it would be helpful to know how the manufacturers approached the problem. He can be very helpful but does say that his email load is very heavy.

I can't suggest a specific source of an existing item and, apart from the cost of such things bought as spares, there might be some reluctance to sell them for use on a "foreigner".

Thanks - although it looks as though they "went bust" some time ago.

I think my own modest set of BMKs was bought about the same time ago; rather like spindle hole size one never has enough!
