Unkel Kunkel Posted May 7, 2019 Report Share Posted May 7, 2019 I can’t remember when I got this device - and it was ancient then. Just used it successfully and mention it here as a curio It does work surprisingly well I wish I had one in other than BSF which I don’t encounter too much these days. Can you get them in UNF / Metric or is it from a by- gone age ? Link to comment Share on other sites More sharing options...
steveweblin Posted May 7, 2019 Report Share Posted May 7, 2019 There is UNF version one on eBay now: https://www.ebay.co.uk/itm/Edwards-Unf-Bolt-Saver-Tool/192889430933?hash=item2ce91b2395:g:MQEAAOSwOz5csy~H Link to comment Share on other sites More sharing options...
Unkel Kunkel Posted May 8, 2019 Author Report Share Posted May 8, 2019 Yes, they do seem to be around sometimes on EBay as you noted ,Steve. Useful yesterday recovering a 1/4” BSF bolt on something very old. They aren’t as ancient as I thought. Lawrence Edward Lamude got his patent in 1953. -Younger than me.

Colin Lindsay Posted May 8, 2019 Report Share Posted May 8, 2019 Interesting! I thought it was akin to a die but it says the threads are recovered by a 'squeezing action'; is this just another term for sharpening / redefining the thread and means exactly the same thing? The one in that link has now sold. Link to comment Share on other sites More sharing options...
68vitesse Posted May 8, 2019 Report Share Posted May 8, 2019 Always liked old tools, main reason I go to car boot sales. On eBay but think it is marked WHIT so Whitworth https://www.ebay.co.uk/itm/VINTAGE-EDWARDS-BOLT-SAVER-ONE-OTHER/163642327379?hash=item2619d7c153:g:7msAAOSwysVcrTiq Regards Paul Link to comment Share on other sites More sharing options...

I was at a great show on Monday, my first of the year so far, and being a lorry / tractor-based show there were loads of boxes of old tools and sockets in the autojumble. As a contrast, some of the stalls were selling modern spanners and pliers, and they were already rusting just sitting on the display... Link to comment Share on other sites More sharing options...
Pete Lewis Posted May 8, 2019 Report Share Posted May 8, 2019 the difference being these cold roll the thread back into some shape where as a die nut cuts a thread and removes damage Pete Link to comment Share on other sites More sharing options...
JohnD Posted May 8, 2019 Report Share Posted May 8, 2019 Hmmmmmmmm! Patented 1952, in the height of post WW2 rationing, "Export or Die" and austerity. When the UK couldn't afford a new bolt, even when an old one had knackered, corroded threads. Has it's miraculous reapperance at this time signalled a re-ride on the "You never had it so good" boom that followwed , or the inflation that fuelled it?

Unkel Kunkel Posted May 8, 2019 Author Report Share Posted May 8, 2019 If you like fascinating odd patents and inventions - (and If you have’t heard of him) I suggest looking up the inventions of Granville Bradshaw. The (flawed ) genius of aero engine, ABC cars and motorbikes. toroidal engines designs also 3 D television and security devices andeven lots of patents for slot machines.

John I think it's reappeared given the price of new bolts.... some suppliers have one heck of a mark-up on the things as opposed to local hardware stores (if you can find UNF in your local).

Badwolf Posted May 10, 2019 Report Share Posted May 10, 2019 Was the quality of steel any better in the old bolts. I have noticed the tendancy for some of the new stuff to strip threads more easily, or maybe it just me overtightening! Link to comment Share on other sites More sharing options...

Hello I think un marked heads are likely to be EN8 But most of our Classic Car bolts would be R or S quality (marked on the head) Nuts were marked differently ooo on the flat or circle with letter on one face Thinking about it ooo,s maybe just UNF! Roger ps there is a lot of rubbish stuff out there now! but good ones will still be marked! (I suppose the they could be fakes!) Link to comment Share on other sites More sharing options...
Badwolf Posted May 10, 2019 Report Share Posted May 10, 2019 My Dad worked in the steel industry all his life and in the 70s was horrified at all the rubbish steel that was being shipped to the far east and coming back as Datsuns!! Link to comment Share on other sites More sharing options...

Colin Lindsay Posted May 10, 2019 Report Share Posted May 10, 2019 In a few years time all the classics will be plastic anyway, so no more worry about metal.

JohnD Posted May 12, 2019 Report Share Posted May 12, 2019 Just happens that I came across this today, the Real Thing: https://www.ebay.co.uk/itm/Blue-Point-External-U-S-Small-Tool-Thread-Chaser-Set-TR-20-C/163457589313?hash=item260ed4e041:g:n-EAAOSw55FcJ8bn Made by Mr.BluePoint Mr.Sealey does one similar in the UK, but it looks a little cheap: https://www.ebay.co.uk/p/Sealey-AK315-Universal-External-Thread-Repairer-Chaser/23011726308?iid=153182552067 These have a hard insert shaped to match the threads you wnat to restore, that attaches in the jaws, and you wind the bolt against.
