|Thread: Picador Grinding Wheel Flanges|
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!
|Thread: Bench block for small parts - ice hockey puck|
I wonder whether, with a suitable slot, they would be heavy enough to make a stand for a mobile phone?
|Thread: Stuck oil filter|
If really stuck it may be possible to drive through a long cold chisel from the side and use it as a lever.
|Thread: Quorn Mk3|
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".
|Thread: Any one used a digital microscope for micro turning on a lathe|
Dan Gelbart of YouTube does: see his video about his "granite" lathe.
|Thread: Parting Off|
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.
|Thread: Die filers for beginners?|
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.
|Thread: Parting Off|
You clearly got the link to work but I'm blessed if I can! Would you mind posting the appropriate search string?
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.
|Thread: Thread Gauges|
Thanks for the useful recap!
|Thread: Meddings Driltru Handwheel (Star Wheel) Stiff|
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.
|Thread: Call for Classified Ads for MEW 285|
Thank you. That seems sensible.
Is it a maximum of 35, 36 or 40? Or just the editorial discretion?
Not sure what the tilde (~) means in this context.
|Thread: Torx head variant or faulty batch?|
Or perhaps more appropriately Alec Guinness' hot box from Bridge on the River Kwai!
|Thread: Pet peeves!|
But, so far as I know, M&W didn't!
|Thread: Holbrook Lathe Information Please|
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" ".

|Thread: Closing down sale ,1930's tool catalogue|
Fascinating stuff! For some reason it reminds me that Gamages had an establishment there, too.
|Thread: Lathe Identifier|
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".
|Thread: Slot drills in a woodworking router?|
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!
