Thread: wind up torch
30/01/2012 15:07:11
The Baylis one I got has an NiMh battery and a "three phase" contactless power winder using neodymium magnets
 
That Baylis chap was the guy who invented the clockwork radio in the 1980s
 
So on paper it seems to be pretty good, first impressions were very good.
 
...will see how it goes...

Modern LEDs seem to be very versatile.
I had some useless-for-my-camera "heavy duty" hyundai batteries and some poundland bits.
 
So I broke an LED from a 7-LED $1 headlamp array and wired it up manually, then deliberately wired it the wrong way round to see if it survived.
 
If you need a low level light source then one LED is fine.
The 7-LED array would have made a very good source for a lathe light, it's knackered now though, I presume they were wired in series/parallel...whatever
 

If you have any clever ideas, modern LEDs from those poundland shops appear to be a real doddle to work with

The masterplan is to use is as a permanent "nightlight" in the hallway, on one LED
 
A couple of minutes winding should cover the entire evening, just leave it on.
It's supposed to last for 5 days on a full charge...uh-huh, okay, we shall see.
 
I'm always wandering about in the pitch dark as I move from the bedroom to the kitchen etc and I just KNOW that one day I'm going to fall over the damn dog or something daft
 
At the very least it will be getting a thorough testing

More a gadgets thread I suppose
 
I've had a few wind up torches which have been...kinda ok but nothing impressive but tonight i was at a friends when I had to go and find the dogs in the garden
 
So I got handed this dogchewed windup torch which was a nice solid rubber/plastic QVC unit which was dead, and spent a few seconds winding some power into it
 
When I went outside it lit up the whole damn garden, it was a gadgeteers dream unit, lasted for ages too
It doesn't matter if your electricity gets cut off for a week or you're away camping or scrabbling about in some dark corner of the garage or garden or the car breaks down in the middle of the highlands at midnight.
You've got a really good bright light "forever", they really do have these things sorted out now.

When I got home I bought one instantly
 

 
 
A few manufacturers sell them, Baylis and TCL to name two
it has 5 LEDs
self winding maxi pro torch
Prices are highly variable so search about
 
You could quite happily go and live in the jungle or the Sahara for a year with this kinda gear, torch batteries are finally truly obsolete

It's called getting some skills Wolfie
Welcome to the club
 
An interesting video here for those sturmey archer bike hubs, about the production processes and the workshop area which made those little gear hubs for the middle of the back wheel on a bike
 
This gives you some idea of the huge amount of effort required just to make one little bit of kit accurate and reliable for selling to the public
It's quite a big file, 85 odd megs if memory serves, great viewing though, a real eye opener
Some of their machines were as big as a bungalow.

Thread: think tank
27/01/2012 14:43:43
Probbly used too much bandwidth as well, too many $s
Google can be used to search a site
 
Put this kinda thing into the Googlie bar
 
site:model-engineer.co.uk "digital cross slide"
27/01/2012 11:13:04
Resources would be better spent on a better search function
At the moment you can only search the thread title
There should be a thread content option
 
Then nothing could ever get lost and original threads could be brought back into play when needed

Thread: Double thread T- nuts
26/01/2012 14:52:20
I don't have the family braincell this week...
 
Looks like a neat idea
26/01/2012 12:40:35
With my own t-nut slots there wouldn't be enough room for 2 threads, and it would strip.

Specially hardened metal might work...but then the nut would probbly strip...
 
To me. T-slots only look wide enough for a single threaded nut.

If there are software related issues it might be worthwhile asking on the Yahoo sites
 
BBC basic, DOS etc there's quite a few retro language places around
26/01/2012 00:39:15
Is this it?
 
 
 
Thread: Another broken tap thread

Yup.
Go carbide.

I just drop my castings into a bucket of guiness
 
Al stress is relieved within 24 hours
Thread: Shesto cadet lathe
24/01/2012 09:39:04
I have a lot of old cnc piccies, obsolete denfords and emcos, but none of mine ride on circular ways
 
Is there a tailstock and is it on circular ways?
 
Would be interesting to see a piccy
 
The Emco compact 3 is the closest I can find
 

23/01/2012 19:11:16
Is that a CNC unit
 
Like the Denfords?

Hi Terry
Rarity value.
It takes time to make so value is added.
regards David
 
 
But it doesn't really go up in value, it's a bit like gold.
 
Sold around 1970 for 2000
Which would buy 3-4 big houses
 
Sold recently for 200,000
Which would buy 2 scroggy flats
 
So it's only an inflation buster, not a growth investment.
 
...and it's a nice watch too...
22/01/2012 22:28:44
It's not really a watch.
It's a unique piece of artwork made by the hands of a master craftsman, and it happens to tell the time too
 
A bit like the Mona Lisa vs a nice poster of the Mona Lisa
 
edit:
(now go and eat your fish fingers you working class oik)
 
Most of these things are "eye of the beholder" things
 
My favourite watch, can't part with it, uniquely thin, 4mm, lovely bit of engineering
It's a Timex about 1980
 
Probbly worth $50 tops, but a lot rarer than a George Daniels watch

Thread: New 'retro' lathe by Warco
22/01/2012 22:16:22
With Myford gone this is the perfect time to bring out a "proper" lathe
 
Modern stuff isn't too keen on low torque work, particularly if you're doing it for hours.
 
I wanted to knock an approx 12mm x 12mm hole in a bit of square steel with my 12mm endmill last night and at high speed (300rpm!) there was miles too much vibration.
 
Engage backgear...munch munch munch...job sorted in 60 seconds with no hysterics whatsoever.
 
Saved me progressing to a 10mm drill then messing about and setting up a boring bar for making a 12mm hole.
 
Sometimes backgear can make what seem to be impossible tasks easy peasy lemon squeezy. Having experienced backgear for a year or two now, I would never look at a lathe which didn't have it.
Mine was broken when I got the unit and fixing it transformed the unit into a far more versatile and professional machine

He's still got to get paid.
 
If it gets relisted in the next few weeks then the buyer will have got cold feet or come up with an excuse to not pay.

Thread: vertical slide or x1 mill attachment
20/01/2012 03:12:19
I've mentioned this somewhere else before.
 
I've found 2 flute slot drills the best, you can resharpen them with an ordinary grinder.
 
4mm or 6mm size and light cuts.
 
Asking too much from a milling slide usually leads to disaster, I also bolt a "backstop" at the side of my slide to increase the resistance to side forces as you mill.
 
gl
 
edit: I recently renewed my main leadscrew nut, having burned through two in two years.
No backlash has made a huge difference.
With milling, every tiny improvement you make makes things better.
Locking the saddle for instance, when possible.
