Thread: Back to Imperial
18/09/2021 06:08:54
Posted by Peter Greene on 17/09/2021 22:16:18:

'Imperial' is not ipso-facto fractions. I have never in my whole (Imperial) Engineering life used fractions, or seen them used seriously on drawings or elsewhere. 37/64 would be 0.578 ±whatever

You were lucky, in the DO where I worked in the 60s all the drawings used fractions such as 37/64" with the occasional decimal one where a tighter tolerance was required, it was only when working for another company in 1971 when the UK changed to decimal currency that the company changed from inch fractions to drawing in millimetres, and both these companies were large Multinationals.

All the photos show up for me with no problems at all, some great work there to take on, I'd just have bought her a new one.

I've just gone to the site and all seems normal to me,

last sale ad is for "Schaublin ES40 collet set" posted yesterday the 4th approved on the 5th at 00.23,

I use mine quite a lot on my Sieg milling machine, mount in either the drill or collet chuck and it's so easy to run the table along and square up a vice or angle plate etc.

Thread: Barbeque Time
18/06/2021 08:38:34
Posted by Lee Rogers on 18/06/2021 07:10:33:

I've just retired from the cheffing game and the thing that has always puzzled me is this. Why does average guy who never cooks decide to give it a go outdoors in the rain using a method invented by a bloke in a cave several millenia ago? Back then the cooking was hit and miss, cave blokes food was lucky to be dead let alone cooked when he ate it so no one was bothered by the results, but we've moved on chaps. So why?

You could put a similar question to the guys on here who spend hours playing around with steam engines etc when there are far more efficient and cleaner methods of obtaining power and propulsion.

Anyway I don't BBQ in the rain but I do think that steaks cooked on BBQs taste much better, more like the flame cooked ones you get in steakhouses.

eBay, is also a great source for Myford parts and accessories. I have found most of what I need there - sometimes it just requires a little patience. Unfortunately, with search set to worldwide, one has to wade through hundreds of listings of cheap and poor quality accessories out of India - dozens of sellers touting the exact same products which really swamp the results - it is a pity that eBay doesn't offer a way of excluding certain locations.Edited By clivel on 14/06/2021 06:27:06

When your eBay search results are listed can't you just scroll down the filters on the left hand side of the eBay listings and set the location? It will default to worldwide on your next search but it's many times quicker than wading through everything, I can set mine to only list items to within 2 miles of my address if I want but normally use UK only.

John

Unfortunately not, as I am in Canada and not the UK. The options I can choose from for location are: Canada only, North America only, or worldwide.

So, if I want to find Myford items which for the most part come from UK based sellers then I have to choose worldwide which unfortunately includes hundreds and hundreds of items out of India, many of these are identical items from different sellers which makes scrolling through the results very difficult.

Clive

That does surprise me, I thought that you would have had better search choices or at least the same as us, there is also a little window at the top right of our search results which by default says 'ending soonest' if I click on this I get various choices to list results such as, nearest, highest price, lowest price, newly listed etc.

I've just done a test search on https://www.ebay.com the USA site, I don't know if this is the one you would use in Canada but there is an different option to ours at the top right of the page which reads 'best match' and clicking on this gives 'distance nearest first', but of course this wouldn't necessarily list UK first, my apologies to you if you have already tried these suggestions without success, as we say, I'm not trying to teach my Grandma how to suck eggs'

Thread: NEW SCAM
05/06/2021 13:15:00
Posted by Rockingdodge on 05/06/2021 10:38:28:

Just received a text from Parcelforce @ 09:37 saying they missed us earlier and to book a redelivery via a link.

The link 'looks' valid but I went straight on to the Parcelforce website and entered the 'tracking number' manually and guess what? It's not a valid number.

I entered the mobile number 077750 99726 into a valid mobile search (there are a number of sites that come up as not tested by Norton) and it is located in Indonesia.

If you're a person expecting a delivery you could be easily taken in by this one.

Roger

You're right, If the scammers are lucky and get the timing right it can make it look very authentic, I renewed my TV licence on line a few weeks ago, about 3 days after renewing I got an email saying that my bank had refused payment for the licence renewal and could I please click the link they kindly sent me, I did click but is was the delete key.

When I used to buy ply for my boat the marine ply standard 'BS 1088' and 'WBP' standing for weather and boil proof were stamped on the sheets.

Thread: Inherited ML7 in need of some love - where to start?
14/05/2021 08:39:06
Posted by Tom Grace on 14/05/2021 07:43:00:

The cover for the drive belt from the motor doesn’t fit due to the clutch. I’m assuming this means the clutch was an aftermarket add on?

When I fitted a Mk2 clutch to my Mk1 Super7 I just used a 50mm dia hole saw to cut out the guard and fitted a spacer and plate over the protruding clutch shaft.

Thread: Quick release collet chuck clevis
07/05/2021 05:47:59
Posted by Lathe-argic on 06/05/2021 21:58:23:

I should be able to hold a bar of silver steel in the vertical slide, using a milling attachment in the lathe chuck, and mill a recess to form a u-shape or clevis. Then I can drill a hole for the bolt. Apologies, I was suffering from a lack of confidence mainly due to inexperience. I realise this is prohibitive to learning.

There's no need to use silver steel at all, you're just making things difficult for yourself, mild steel is perfecrly satisfactory.

The one I made for my S7 is very much like this one in the link, 3rd photo down with it screwed in the headstock.

When I got a Myford quick release collet chuck for my S7 Mk1 it also came missing the clevis, it's a simple thing to make assuming you have access to a milling machine, if not you could even hacksaw the clevis cutout, no particular accuracy is required, it only works for a few seconds to open or close the collet, the rest of the time it just sits there, for the clevis pin itself I just drop a m6 bolt through the hole.

I've got to go out now but if you want I'll try and put up a photo of it later and list some sizes, but I've no idea what you have exactly with the ML7 attachment so no guarantees that what I have would fit yours.

Thread: Reading glasses - frosted area
04/05/2021 11:55:46

Be careful not to take off too much and change the optical properties, I had a tiny scratch on the car windscreen which I had professionally polished out, it looked excellent afterwards but when a cars image filled the polished area it looked all distorted, I had to replace the screen.

Letting the answering machine screen your calls is pretty effective.

Not if you have someone in the house who cannot not-answer a ringing phone.sad

Seems to be a psychological thing, even if it's a 95% chance of being a spam call they still pick it up

But not picking it up that means there is a 5% chance of missing an important call.

Thread: What odd grease?
29/04/2021 13:28:01

Hi Andrew,

I'm not being picky but the motor / gearbox is almost certainly a Fracmo not Framco, might make searching a little easier, there seems to be quite a lot of info on the web regarding them.

Thread: Electric Smart Meters
01/04/2021 10:43:40
Posted by old mart on 09/11/2020 18:39:16:

We have had smart meters for electricity and gas for a couple of years now. I was not impressed by the kid who fitted them, just the minimum of training to be certified, but not any sort of proper fitter. The silly gadget they give you to monitor the consumption is sitting unused in a drawer. The only possible advantage could be that the meters we had were very old and that we don't have the meter reader needing to be let into the garage periodically.

We had them fitted last week, the chap that did them seemed to do a good job, he replaced all the wiring from the mains in to my consumer unit including a new mains isolator and moved the gas meter further away from the electric meter etc, it took him over 5 hours and he was most apologetic for the time taken and thanked us for patience, like yourself I also don't use the silly monitor gadget, the plus side for me is I don't have to clear out all the stuff under the stairs every month and crawl in with a torch to read the meters.

Well, actually ... I wouldn’t

It’s a parallel clamping action, generated by the tapers and the slots

... the internal profile is trivial

MichaelG.

I'm not saying you're wrong it's just that I'm also having trouble visualising it, say a 12mm collet is being closed on a short length of 12mm shaft by the tapers, once the collet clamps onto the shaft it can't be closed further and everything stays parallel, both the internal 12mm diameter and the tapers, even clamping on to a 12mm ball would prevent further closing of the collet in its taper, I do realise that the longer length that is in the collet the greater the holding power will be for milling cutters etc.

John

I think we may be ‘on different pages’ , John

Tony and Jason have addressed your point nicely ... but my comment was a specific response to ‘old mart’

i.e. The internal shape of the collet’s bore is trivial when understanding the closing action of the collet.

.... the ones with stepped bores obviously ‘get away with it’ when there is sufficient length being gripped in the larger bore, but I wouldn’t trust any collet to reliably grip a 3mm insertion length. [which is, I think, what Bo’sun was contemplating] unless the material was less than about 1mm diameter.

You would think that the parallel clamping feature would mean that the collets always had one diameter right through. I have some er25 collets with only half the length at the nominal size.

Thread: New car - or is it a wheeled computer?
26/03/2021 10:15:09

Glad to see the back of old cars, having done jobs on them like replacing a smashed piston and wet liner on a 1950 Vanguard without even jacking it up, barely able to get under it to remove the sump and big end cap, getting covered in oil and freezing cold, years of jobs like this, Mini's with always damp electrics having to take the distributor cap and leads into the house to dry them out in the oven before I could drive to work, now I've not seen a spark plug for 17 years on my last 2 cars, first time starts every morning, never broken down and no rust, cumfy seats, air con and good safety features, that's how I like them.
