Thread: What are you reading?
20/03/2020 12:14:49

A lot of earnest stuff so far, and nothing wrong with that, but for something a bit lighter I'm re-reading some of George MacDonald Fraser's Flashman books . . . also available as audiobooks on YouTube. One of the most enjoyable ways to learn some 19th century history smile

Thread: Holding End Mill on small lathe
16/03/2020 20:31:17

Having done a limited amount of milling on my C4 lathe, using MT2 collets in the headstock, I am genuinely puzzled as to why anyone would deliberately introduce extra flexibility into an even more lightweight machine than mine by putting a secondary collet chuck in the morse taper, moving the cutting point further from the headstock bearings for a job where rigidity would seem to be one of the most important factors.

I have also achieved quite good results with a MT2 mounted fly-cutter. Again, the rigidity is better close to the bearing.

There must be a serious 'down side' to morse tapers that I haven't yet discovered if so many people dismiss them so easily . . . dont know

Thread: New computer possibly required
01/02/2020 10:47:33

I have had two PCs and a laptop over recent years from It might be worth looking at their web site where you can 'customize' your own machine. They will also supply without an operating system installed. The only drawback is that, being built to order, you might have to wait a week or so for delivery.

No connection except as a customer.


Thread: Why does everyone disagree with you
30/01/2020 17:18:52

Well, I don't know much about angels but this thread certainly seems to have grown wings and ascended to a higher plane. Such erudition and eloquence is rare on the interweb; long may it continue . . . well, at least until the weather improves and the sheds warm up a bit.

As a 'farm boy' my knowledge and abilities are wide-ranging but generally lacking in depth so I do enjoy being prompted by such as MichaelG to investigate topics of which I was aware only as a few names and phrases.


Thread: Desoldering how to?
24/01/2020 12:54:51

If they are normally open switches you could leave them in place and just solder the leads for the remote switches to the pins. Hard to be sure but they appear to only use two pins of each switch so it should be fairly simple.

Thread: Havenít done this for a looooong time!
27/09/2019 20:12:35

One of my first lathe bodges was filing two parallel flats on the head of a cup square head coach bolt to make a passable tee bolt. It needed a little refining of the square shoulder to fit the tee slot without binding. Often it is irrelevant whether the nut is on top or bottom, although clearly not always the case.

Thread: Havenít done this for a looooong time!
27/09/2019 10:25:21

My admittedly limited experience with a Unimat SL taught me that one of the most important things was to use really sharp HSS tools. I never tried carbide but my subsequent experience would suggest it is not really rigid or powerful enough to make good use of them, although someone will probably come along who uses them all the time.

It was a sweet little lathe and I still have some regrets about selling mine a few years ago but it was far too small for some of the jobs I wanted to do.

Thread: Blown Fuse
13/08/2019 22:57:28

Finally found a reference here to prove my memory still hasn't completely failed regarding aluminium burning.

It clearly requires a particular set of circumstances, but I would suggest it is a possibility.

I would be really interested to find out exactly what did happen.

Just a further thought, pursuing the lightning theory: is the workshop supplied by an overhead power cable? Or is there anything else that might act as a lightning conductor in the vicinity of the lathe? Having asked that I'm thinking you should have felt something if it was a bolt of lightning while you were hand feeding!

Reading the original post again, and some of the answers, I'm more incliined to wonder if there might have been some sort of inclusion in the aluminium which caused a spark. I seem to remember reading that fine aluminium swarf/dust can ignite violently when suspended in air, although I have no experience of it. I still can't think of a connection between either event and the fuse blowing though . . .

12/08/2019 23:13:40

As Phil says, it should be almost impossible for there to be a potential difference between tool and work . . . unless there was, say, a plastic sleeve protecting the workpiece from damage in the chuck jaws dont know Even then the tool should conduct any charge away from the workpiece while it is cutting.

The metal-to-metal contact between component parts of the machine, including the bearings, should equalise any static charge build up. I'm not sure any sort of static charge would blow the mains fuse anyway as there should be no connection between that and the machine chassis. The fuse 'blows' when it passes excessive current in the live supply lead.

Very strange . . . can we asume you don't have a modern consumer unit with MCBs etc? If you did, surely this would have tripped out if there was a short-circuit anywhere in the power supply.

Just some random thoughts to throw in the mix . . .

Thread: Floor Paint
02/08/2019 11:15:07

I may be getting over-cautious in my old age, but I would never use just paint or varnish on stairs since slipping on someone else's varnished stairs a couple of years ago, wearing socks without shoes. Still feeling the result of a very nasty sprained knee even now. Her grandson did the exact same thing the following day, but they bounce better at that age wink 2

I always make sure not to use those stairs without rubber soled shoes on now.

There are proper non-slip floor paints but I don't know of any in colours I'd want indoors sarcastic


Thread: A little rant about Emojis and their kin
18/07/2019 10:12:31

Anyone know what they're for ? dont know

I can see the point of a little smiley face, winking smiley face, etc. to indicate the perhaps humourous intent of the sender and avoid some of the bad feeling generated in recent threads on here, but I'm not sure what any of the new issue would indicate to the reader . . .

Thread: Electricity Supply
14/06/2019 09:57:16
More good news if you're Australian; not only does the continent have generous reserves of fossils fuels, there's also plenty of sun! It may be necessary for 60,000,000 winging poms to move in...

But if we all move there, surely the World will tilt on its axis and Australia will end up at the south pole dont know

To answer my own earlier question I looked up the energy equivalent of petroleum (crude oil) which the International Energy Agency defines as 11.63 MWh/tonne.

1 million tonnes of oil per week (total used for all transport) = 5,952 tonnes/hour = about 69 GWh.

Current UK demand on the National Grid seems to average around 35GW, so switching all transport from petroleum fuels to electric traction would seem to require an increase of almost 200% in generation capacity, although potential efficiency savings might reduce this figure. However, roughly half current generation appears to be from fossil fuels so we will need to increase generation by at least 400% from 'other sources' if we are to stop using petroleum fuels altogether.

I can't begin to imagine the changes my grandchildren will see, but our current systems will certainly need upgrading pretty soon if they are to have any hope of a decent life, even if my figures are inaccurate . . . which will no doubt be pointed out shortly teeth 2


09/06/2019 10:45:46

However you juggle the figures around, the UK apparently uses about 1 million tonnes of petroleum per week for all transport. plus almost another half million for other uses (according to Gov't figures)

Someone will no doubt be able to work out the electrical equivalent, but that sounds like a lot of gigawatts to me dont know

Think I might start breeding horses teeth 2

Thread: Cutting a concave radius on the end of a round bar
18/03/2019 22:54:32

I think I would make a jig similar to what you suggest, but to fit on the lathe topslide and hold the 3/16" pieces horizontally at centre height at the 45 degree angle, then put a 1/4" milling cutter in a collet in the headstock to cut the concave. I'd be worried, like you, about the drill wandering in your proposed setup.


Thread: Trends in Radio Ads

What I want to see is on TV is a film crew turning up at a tidy persons home with an 'expert' who announces that tidiness is a mental illness, and a team who 'help' by filling the entire house with junk from a skip..

I'd definitely watch that. I could even be that 'expert' embarrassed

If you are not averse to buying one rather than making, it might be worth looking at this site:


I don't get on with normal ladders these day but I found these very stable and infinitely adjustable for uneven ground as well. I have the 'Junior' size which should reach the gutters on a bungalow. They aren't lightweight but they do fold flat easily for storage.

Someone better qualified than me will no doubt advise on your actual question wink 2


Thread: It's not rocket science
12/12/2018 22:25:51

I seem to remember they 3D printed a spanner on the space station a while ago. Not sure if it was for a special job or just an experiment.

I bet those fancy gloves make working with fiddly things interesting, but at least if you drop something it just floats around. Not so good when you're working outside though.
