Thread: Identifying the grade of silver solder.
15/07/2020 11:51:29

When I was gifted some solder of unknown provenance I used Archimedes Principle to work out the proportion of silver to lead. Fine for the more basic plumbers type solder but maybe not refined enough for a more sophisticated silver solders containing more than two types of metal.

Thread: Spark plug lead
07/07/2020 05:17:58

In the motorcycle trade if we had a bike with a damaged HT lead that was bonded into the ignition coil we would use an in-line suppressor to connect the new cable to the old. (example below) This has an added benefit if not using a suppressed spark plug cap.



Thread: Ultrasonics and citric acid

I've got some concentrated derusting fluid for my ultrasonic cleaner that I'm sure contains citric acid.

I usually use it at about 50C


I run my ultrasonic tank at 65C, so in the same ball park as Neil. As a side note, if you've put fresh liquid in your tank and are waiting for it to come up to temperature, its worth running the bath empty to degas it while it warms. This will increase the effectiveness of the bath.

I've used these people recently to buy online and had a quick turnaround. They supply Imperial and Metric sizes and will cut lengths to order.

Thread: Ultrasonic toothbrushes

So US should be a good way to clean Fido's teeth, as long as not overdone. Possibly, water would be an effective conveyor of the US pulse, since this basically the main constituent of some US cleaning baths.

Give a product a fancy name and you can sell it for a vastly inflated price.

Or am I a cynic?


My company used to sell Ultrasonic baths - I'm not an expert in this area though. From what I can remember, plain old water worked just fine. Some additives would compliment the the cleaning through chemical action acting alongside the cavitation while others would reduce the cavitation. Can't remember which now as its around 25 years ago.

With regards the damage ultrasonics can do, a simple test to ensure the bath was working was to dip a piece of aluminium baking foil in the bath for a couple of minutes. If the bath was working there would be pin holes punched in the foil by the cavitation.

I tried this on my ML7 as well. Not as easy as I expected but a good learning experience. Here's a form thread about it. LINK

Thread: Storage of files

Used a bit of left over Ikea shelving support to make a spacer for the files.

If you send goods by Hermes you probably don't want to watch this investigation by Joe Lycett on Chanel 4 a few weeks back...


Thread: DIY drip feed oiler for cutting fluid
07/06/2020 06:19:42

The bit I liked the best was the idea of using the tool holders behind the lathe to mount the oiler. That's an idea I'm stealing for future use

I'm a died in the wool lover of assembly language, just because...

Back in the dim and distant past when I was doing my Computing degree, one of the things we dabbled with was VAX assembly language. I remember students commenting on how friendly it was compared to some other languages. Where they would refuse to compile due to the smallest of errors 'String and string' being a good example the assembler would really try to execute your code however mangled it was. smiley

Thread: The story behind my forum image
03/06/2020 11:15:02

I had amnesia for a while following a motorcycle accident. My first recollection afterwards was being sat on the curbside in a large puddle of blood. Cautiously checking myself for injury I couldn't find anything amiss. I then realised it was the red TQF oil that had spilled out from a broken fork leg.

Later in the afternoon I was found wandering the streets in a daze pushing a broken motorcycle and taken in by a friend. While sat in her flat I was hallucinating watching a picture over her fireplace sliding from side to side across the wall. The next morning when I got home I was dragged of to A&E by my mum for X rays and such like.

It was only when I was contacted a few days later by the driver of the car I'd hit that I found out another vehicle was involved; the police and ambulance had been in attendance; and that I had refused to get in the ambulance or press charges against the driver that had pulled out on me.

Thread: Workshop Insulation Problem
08/05/2020 06:54:17

I can't comment on the structural side of things, but like Bazyle, I run a dehumidifier in my brick built double garage with an insulated flat(ish) roof. I have it set to 40% humidity and I'm collecting a couple of litres of water every two or three days to once a week depending on outside humidity.

I haven't seen any damp issues in the garage but I run the dehumidifier to help keep my motorcycles and metalworking equipment rust free rather than to deal with structural issues.

I have to confess that it was the accountant in me talking. Slot Drill £7 slitting saw and arbour £21... nerd

You might also be able to use a very small slot drill in your mill. Such as these sold by RDG Metric Slot Drills

Nigel B,

I mostly work with BMW (that's why I took the bait on the GS smiley) but also Triumph and Ducatis now and then. I don't find pushing the big bikes around a problem as I'm a big lad and if you're doing it 8 hours a day your technique gets pretty good. When I was full time I was riding about 4,000 bikes a year. Now I'm retired I just help out running in bikes ready for the press fleets. I know, a tough job but someone's gotta do it!

A lot of talk about the weight of various bikes with the BMW R 1200 GS being described as grossly overweight. As sure as heck it is no light weight at 580lb curb weight. The RE 650 Enfield weighs in at 455lb making the BMW 27% heavier.

However, if you look at their power outputs the BMW knocks out 125bhp and the Enfield a more modest 47bhp. This gives the BMW a power to weight ratio of .21hp/lb twice that of the Enfield at .103hp/lb.

I'm not saying this makes the BMW the better bike, I'm just saying weight is just part of the story. I test ride bikes for a living and can have as much fun on an electric scooter as a 6 cylinder 1.6 litre bike (electric bikes are a hoot by the way).

Give me a bike, any bike, rather than a car any day!

Graham, EPDM rubber (if that's what you meant, but your fingers thought otherwise) is not compatible with hydrocarbons. Nitrile rubber is OK. So your bit left over lives for another day...

Thanks for the warning. I even checked the name of the rubber before typing and still got it wrong!
