If it is, they don't normally get on all that well with gas/air. They were designed for coal/town gas rather than natural gas or propane. Gas/oxygen works better. Either that or a redesigned burner* with flame retention features.

If you look at another ad than the one pointed to by Thor, it states it's suitable for use with butane and compressed air, albeit the "plus" version.

Good luck with that. I think I'd get something a little more modern. The clue is in the manufacturer's name!

John

That's very interesting, I worked at Pilkington for 30 years and have visited two Chance factories, Smethwick and St Asaph and seen plenty of gas torches but never knew Chance made them.

Also slightly off-topic

The shop I used to buy hardware fittings from would sell you a 'pair of hinges' if you wanted 2 and 'one and a half pair' if you wanted 3, I don't know if that was a normal ironmongers expression or not.

Thread: Railway station toilet signs

Two signs for toilets on a foreign railway station.

Next one said -- The second class toilet is off the edge of platform 3.

The now closed Platt Bridge railway station in the Wigan area is often referred to locally as 'Platt Waz', supposedly because in the days of old the train driver would stop at the platform and go and relieve himself ' have a waz' by the bridge.

Thread: Electrical calculations

I often see the equation V = I *R, where current is calcuated.

It should be noted that the actual equation that should be used is V = I*R*cos theta

where cos theta is the power factor.

I learned early in my career just how important the cos theta is.

It's a long time since I did electrical calc's at night school but isn't the power factor shown as Cos ϕ or Cos phi not cos theta?

Thread: Learn to use a metal lathe
16/02/2022 11:04:40

Hi Eliza,

You should definitely take someone experienced with you for advice when buying a lathe especially a second hand one, someone with a bit of experience but with no interest in buying it will see a lot more shortcomings than you will (standard advice for buying cars).

For example I first used a lathe at school in 1956 but spent most of my working life in a mechanical engineering drawing office as a design draughtsman so I'd seen many varieties of lathes in the workshops but not used them, about 30 years ago I was looking to buy my first lathe and heard about one for sale, drove to the house and there was a clean looking lathe, can't remember the make but it ran and all seemed OK, plenty of bits and pieces with it, luckily I said I was interested but would confirm later, on the way home something started nagging me, after about 20mins i realised I hadn't seen a tailstock, got home and rang him up and he sheepishly confirmed my thoughts.

It's so easy to get carried way when you want something and take the wrong decision.

I know there is a lot you can do without a tailstock but there's also a lot you can't

Thread: An unpleasant nocturnal experience.
14/01/2022 09:29:45

Thankfully not quite as dramatic as Clive's rat experiences but still on the subject of animal pests, About 20 years ago my wife and I spent a fortnight in a ground floor chalet in Gran Canaria and every evening when we came home and opened the door half a dozen or more cockroaches were scuttling around the floor, to dispatch them I kept the door mat rolled up ready and quickly whacked them all and kicked the bodies out onto the patio, every morning when I went out they were gone so I just assumed I hadn't hit them hard enough and they had recovered, but one morning I got up a bit earlier and went out and saw what was happening, there were two long lines of ants, one led to the cockroach bodies where they were dismantling them, the other line of ants carrying bits of legs, wings and bodies led into the garden area to their nest, nothing was left at all, wish I could have filmed it.

Thread: Bench grinder to polisher
02/01/2022 15:05:20
Posted by mgnbuk on 02/01/2022 11:28:53:

How sucessful this will be will depend upon how powerful your grinder is & how much polishing you wish to do.

For polishing I have a 0.75KW single phase motor with a suitably parallel bored "pigtail" attached. It is clamped in a Workmate by the feet when used. I can't recall the size of the mops I have without a measure-up, but think they may be 8" & I can stop this machine as well if I get too enthusiastic.

Be aware that polishing is a hot & dirty business !

Nigel B.

I use almost exactly the same set up regards motor and mop size and like Nigel I can stall the motor if I press too hard on the mop.

Thread: What do you do about cookies?
02/01/2022 12:34:12

I just accept all the cookies and leave everything on, I did clear them all once and then had to manually log in to all the websites I go to, and in the case of places like Screwfix, B & Q, and Toolstation also enter my address etc to find the local stock situation.

Yes I would say a Ballistic Galvanometer as well and the clamp is to lock the movement.

Thread: To harden or not to harden that is the Question
27/12/2021 19:55:32

About 25 years ago I bought some machined lengths of 'T' strip from Myford Ltd, this was not hardened as you had to both cut it to length and tap to it suit.

Thread: jury service
02/12/2021 19:46:41

It must all come down to the type of case you have to be a juror on, I found it very interesting but the 2 cases I was on were not too serious, the first a criminal case was dismissed by the judge after a couple of days because of prosecution evidence failings and the second was a civil case where we had to reach both a verdict and also decide on damages, however tonight I've just watched the BBC news report of a 6 year old boy who was tortured and murdered, his father being guilty of manslaughter and his partner guilty of murder, both guilty of child cruelty, the case lasted 9 weeks, just watching the TV news reporting details and a few moments of actual footage showing his suffering brought tears to my eyes, but to have to endure 9 weeks of it, it would have to be done and would give great satisfaction to convict the guilty but could leave you traumatised for a long time.

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.

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'
