|Thread: wind up torch|
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
|Thread: Milling - difficult to gauge exact cut|
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|
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"
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|
I don't have the family braincell this week...
Looks like a neat idea
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.
|Thread: Shesto cadet lathe|
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
Is this it?
|Thread: Another broken tap thread|
|Thread: Stress relieve in castings.|
I just drop my castings into a bucket of guiness
Al stress is relieved within 24 hours
|Thread: Shesto cadet lathe|
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
Is that a CNC unit
Like the Denfords?
|Thread: Books for model engineers|
It takes time to make so value is added.
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...
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
(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|
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
|Thread: Myford Rodney|
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|
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.
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.
