Thread: Failed to get this digital clock kit working :(

Michael, Not commenting on faulting this circuit, but I do note you saying that your scope is in storage.

If you have a variac, it might be worth powering up your scope slowly to give a bit of time for the capacitors to re-form.

David, This brief article is worth a read
http://www.racingvincent.co.uk/14%20Norton%20Site/Manx-Norton-28.htm

PM me your real email address and I'll send you a couple of documents over tomorrow.
I can't remember where I found some of them, so I'll not reproduce them here.

Thread: Alfred Herbert high speed bench drill
03/05/2021 13:19:09
Posted by Mike Poole on 06/03/2021 15:12:31:

The Meddings high speed drill has additional pulleys to implement more speeds, the pulleys are quickly released with a thumbscrew and the pulleys are a light push fit on the shafts. Could the Herbert have a similar arrangement?

Mike

Mike, do you have one of these, with the original extra pulleys?
If so, would you mind measuring them for me please.
Thanks

W10 has hidden all my file extensions, creating chaos in my astro image store where I often have a 16 bit tiff, 8 bit PNG and 8 bit JPG of my finished images, not to mention FITS, TIFFs and other versions of un or partially proccessed files.

Grrr...

In the top banner of the "View" tab in Windows Explorer, there should be a tick radio box to show/hide file extensions.

Thread: Interesting old chisels
02/05/2021 20:42:40

Dave, Reynolds the razor maker were a Sheffield company making razors themselves; I actually used to live on a road off Gell St in the late '70s, though I suspect Providence Works (Variously, No.60 or 116/8, depending on the source) may have been demolished by then.
https://www.hawleysheffieldknives.com/n-fulldetails.php?val=rE&kel=1045

Note that on the blades of the razor(s) the logo of the boat and Oxford Wins appears to be etched, or engraved, rather than stamped. Also it seems that, rather than three rowers, it's actually a pair plus cox.
This was obviously done post grinding, so it seems unlikely that it was a logo on the steel blanks.

I like the Oxford Works connection from 1877 but the logo and slogan are associated with 3 different makers, Hearnshaw, Wilson and Chapman.

.............................

Dave

Dave, where did you find the references to Wilson and Chapman as also using the logo of 3 men in a boat, and what dates?
Everything I've found, and linked to in my previous post on Page 1 of this thread, suggests Hearnshaw were a maker of Edge Tools, amongst other things. There's at least 4 individuals involved, all with the same surname.

They don't appear to be listed in the 1879 Whites Directory as advertisers, but are shown at 50 Sorby St (Dorking St) on P 375 (of the pdf, P 360 of the directory itself)  as Edge Tool Manufacturers.
http://specialcollections.le.ac.uk/digital/collection/p16445coll4/id/218326/

By 1911 in the Whites Directory, they only had John Bull listed as their trade mark. See P 21

I've still not come up with anything about "T.CHAPMAN" & "SONS" that I mentioned earlier.
However on the Hearnshaw name, I stared to look last night, but it was getting late; Like Michael, I'd also spotted a few tools via Google image search.

It's often worth having a look at the various on-line stuff in the Ken Hawley collection; he was a tool dealer and collector of repute in Sheffield before his retirement.
http://www.hawleytoolcollection.com/index.php?sheffield-tool=the-collection

Part of the collection is Name on a Knife Blade
https://www.hawleysheffieldknives.com/index.php?val=h&kel=1490
where it's interesting to look at both Hearnshaw and Rogers Brothers (Note there are several different entries for various Rogers).
https://www.hawleysheffieldknives.com/n-fulldetails.php?val=r&kel=1064

See also a fairly eclectic site on Billhooks https://www.billhooks.co.uk
I only mention this, as somewhere on their site, and I know not where, there is a direct download link to a pdf of Sheffield edge tool manufacturers
For the nervous amongst you this is a direct link, and doesn't open in a web page.
https://www.google.co.uk/url?sa=t&rct=j&q=&esrc=s&source=web&cd=&cad=rja&uact=8&ved=2ahUKEwiD7cyygavwAhXnQEEAHRKcAEUQFjAEegQIBhAD&url=https%3A%2F%2Fwww.billhooks.co.uk%2Fapp%2Fdownload%2F5783009499%2FSheffield%2BEdge%2BTool%2Bmakers.pdf&usg=AOvVaw33OJ3xqOJRFoz0bXRVKJG4

From that document P16;
Hearnshaw, George (Edge Tool Manufacturer). Residing at 45 Nottingham Street, in 1871. Recorded in: Whites Shefffield & District Directory - 1871.
Hearnshaw Bros. (Manuftrs. Of light & heavy edge tools, etc.). Residing at 50-52 Sorby Street, Sheffield in 1905. Recorded in: Whites Directory of Sheffield & Rotherham.

I've never been able to find an on-line copy of Whites, though there were other subsequent directories as well, some of which are listed here, but again without on-line access.
http://www.sheffieldindexers.com/DirectoriesIndex.html

Here we have another plane with the Three men In a Boat logo, rather than the more familiar John Bull one, which they seem to have acquired in 1889
https://www.worthpoint.com/worthopedia/beech-steel-badger-plane-samuel-162019485

Note that the court case was against different Hearnshaw Brothers, Frank and William, as mentioned in the earlier Rogers Brothers reference.

Lots more to be found I'm sure;

Thread: Kennedy Hacksaw Dashpot Oil
01/05/2021 13:14:22

Chris, you will find links to the manual HERE, where on the 4th one there is a recommendation of Wakefield Cresta V
Wakefield is, I think, the forerunner of Castrol.
I think it equates to an old style 500, which is close to a modern 140 monograde gear oil which is what's in mine and seems to function OK.

I've used them for travel insurance, and had no issues with their documentation.
I'm using a desktop PC on Windows and prefer Foxit reader as well.

I've sometimes found pdfs can be problematic on mobiles and tablets.

Thread: Finding a penknife
28/04/2021 22:49:51
Posted by old mart on 28/04/2021 20:46:20:

I had a look at the bottom with the endoscope through the gap where the rising main goes up alongside the 110 waste. There are too many frame members on the way, the knife wasn't visible from the top either. I am just too arthritic to spend time in awkward positions.

It might be worth while looking on etsy
https://www.etsy.com/uk/search?q=sheffield+pocket+knife&ref=pagination

My own interest is in Sheffield made knives, so The Famous Sheffield Shop is worth a look; lots of variety at mostly decent priced.
https://www.sheffield-made.com/acatalog/Pocket_Knives-p1.html

See also this website, which is quite disorganised, but has lots of good stuff available when you eventually find it
https://www.sheffield-gb.com/

Obviously in the links I've provided, I've added Sheffield as a search term, which can be removed for further products.

Thread: Problems trying to sell-on a 'Swiss' Army knife
28/04/2021 21:57:08
Posted by Speedy Builder5 on 28/04/2021 16:12:58:

I have the same problem with WW1 bayonets - I may take the cutting disc to them and then dispose into the scrap metal bin. I certainly wouldn't want them to get into irresponsible ownership.

Etsy is one possible choice, or if you have a Facebook account, then there are genuine knife/bayonet collectors groups. Mostly they are private to prevent idiots. Like ebay UK, don't try listing openly on Facebook as the posts will likely be removed.

Re. ebay, as far as I'm aware, the issue is buying items in the UK or Eire. It used to be OK to list knives etc, provided that they were only available to overseas buyers, so there didn't used to be a problem listing on ebay.com, provided there was no dispatch to the UK or Eire.

It would be a shame to scrap items of genuine historic interest, and if sold responsibly will likely fetch reasonable money. Selling at a fair price, also has the effect that they are unlikely to get into the wrong hands.

There are also specialist militaria auctions and sites.

Thread: Soldering Electrical Connections to NASA standard

..................

Sorry to go off topic but I feel strongly that the EU regulations were excessively overprotective and detrimental to electrical product life. Dave W

I'd suggest that the lead problem being addressed by the EU legislation is not about the use of lead in the production and use of the item, but more about the mining/processing of the lead ore, and the recycling of the product at the end of its life.
The EU might have been one of the first to introduce relevant legislation, but it has been followed by a number of other countries now.

This link has some useful info; note particularly the bit about the Basel convention, which is a UN, rather than EU creation

Hi Bill, had a look for you on FB but can't find you there, sent you a PM with my name so maybe you could send me a friend request.

............

Cheers Dek.

Dek, not sure which of the folks with a similar name is your account, but the Friends Request restriction on my FB page should now be lifted.

All the best

Gerd, I was one of the folk who bought some of John's kit in his great workshop clearance.
He moved house shortly afterwards, and thus lost his BT email address, so I unfortunately lost contact with him.

I did join Home Model Engine Machinist a while ago, specifically to contact him, but he was last seen there in Oct 2020.

Dek, Thanks for that info, I hadn't realised John was still with us.
If you are still in contact with him and Wyn, please pass on my regards to both of them; he might remember me as as "Bill from Buxton". (White van, White Disco, and the Marlin in my avatar)

Amongst many other things I bought his high speed drill press and 5C collet setup.

Persevere with Facebook, there is some good stuff there if you're selective enough.

Regards
Bill (on FB as peak4, the same as here.)

Can the cross slide take a re- grind as well as the bed?

Yes, the firm I mentioned above certainly do them, so I've no doubt others will too.

Bill

16/04/2021 12:14:08

We don't know where you live, or even which country, but if you're in driving distance of Halifax Yorkshire, then these folk may also be worth contacting re. a bed and saddle re-grind.

I've never used them, and the service doesn't show on their web site, but they do come recommended on other groups.

Thread: LED Tubes in the workshop
09/04/2021 02:31:05

When I had the new garage/workshop built I chose to light it with some 48W 600mm x 600mm flat panel LED lights of the sort that you see in suspended ceilings.
I picked natural light simulation, rather than cool or warm; it's not harsh on the eyes and gives an excellent bright light over the whole place.

6 panels used to cover the 5.5x6.5m area, in 3 separate circuits of 2.

Just for interest, the UK company importing them from India went bust a few years ago
https://www.thegazette.co.uk/notice/2936066

The web address used to be correct, according to the Internet Archive.
https://web.archive.org/web/20161028211527/http://www.teamuki.com/index.php?route=common/home

And you can still import them yourself if you wish, direct from India, but I guess only by the pallet load, and I'm not sure about electrical certification.
https://www.indiamart.com/proddetail/micro-iron-4590020473.html

None of which helps you obtain a replacement lead of course.

Bill.
