Thread: Allchin 11/2" scale
03/01/2012 20:16:21

 
 
 
At a recent exhibition I watched a fellow visitor purchase the book and took the opportunity to mention what a task he was letting himself in for......I am sure that he didn't believe me when I said the I had spent 6 years on my model...he might not take that long, but it may well take him two or three years, depending on his other commitments.

Thread: vertical slide or x1 mill attachment
02/01/2012 12:43:54
Two machine tools are always better than one, more flexibility.
 
So
 
"worst scenario" is the milling slide
 
second best is the milling attachment
 
Bestest would be an independent mill which could be attached to the lathe if required.

Thread: Warco WM-180 or MIni Lathe
30/12/2011 23:50:32
If anyone has a suggestion on a different lathe I should look at then please let me know
 
Some good drummonds with a bunch of gear come up from time to time, with a bunch of bits, costing a few hundred quid.
Accuracy can be improved with DRO bits on all the older lathes
 
 

Have you given up on your Grayson unit?

Thread: Lard Oil or it's modern day equvalent?
28/12/2011 11:56:34
I think it was Sparey who recommended whale oil.
Apparently it's a very good lubricant.
 
There may be a Japanese or Norwegian supplier who can help...
Thread: iPad in the workshop, something to bear in mind!

While we're on an offish topic subject I have a contribution about a "Ten year rule" which aspiring model engineers may find reassuring.
The original article is bigger.
 
Teach yourself programming in 10 years. By Perter Norvig
 
Walk into any bookstore, and you'll see how to Teach Yourself Java in 7 Days alongside endless variations offering to teach Visual Basic, Windows, the Internet, and so on in a few days or hours. I did the following power search at Amazon.com: 
     pubdate: after 1992 and title: days and
      (title: learn or title: teach yourself)
and got back 248 hits. The first 78 were computer books (number 79 was Learn Bengali in 30 days). I replaced "days" with "hours" and got remarkably similar results: 253 more books, with 77 computer books followed by Teach Yourself Grammar and Style in 24 Hours at number 78. Out of the top 200 total, 96% were computer books.

The conclusion is that either people are in a big rush to learn about computers, or that computers are somehow fabulously easier to learn than anything else. There are no books on how to learn Beethoven, or Quantum Physics, or even Dog Grooming in a few days. Felleisen et al. give a nod to this trend in their book How to Design Programs, when they say "Bad programming is easy. Idiots can learn it in 21 days, even if they are dummies.....

.........Researchers (Bloom (1985), Bryan & Harter (1899), Hayes (1989), Simmon & Chase (1973)) have shown it takes about ten years to develop expertise in any of a wide variety of areas, including chess playing, music composition, telegraph operation, painting, piano playing, swimming, tennis, and research in neuropsychology and topology. The key is deliberative practice: not just doing it again and again, but challenging yourself with a task that is just beyond your current ability, trying it, analyzing your performance while and after doing it, and correcting any mistakes. Then repeat. And repeat again. There appear to be no real shortcuts: Even Mozart, who was a musical prodigy at age 4, took 13 more years before he began to produce world-class music.
 
 
 
 
Thread: What use is a washer
27/12/2011 04:41:35
with the obvious exception of spreading the load of a smaller headed fastener
 
That's the main use.
 
Either make a bolt out of a solid 20mm bar
 
Or make a bolt out of 14mm bar and add a one penny 20mm washer
 
...and multiply the money/resources saved....by one billion...per week
 
....which soon adds up to a serious chunk of change

Mr Meek returns...I had a second take as I saw the name there.
 
Welcome back sir, and a merry xmas.

Thread: Blackgates power hacksaw drawings
25/12/2011 21:22:34
I like the old Drummond Ady, I've got to sort out the wiring and a toolpost for mine before I get it going.

You are a lucky man
You have one of the best 3.5 inch lathes ever made.
25/12/2011 12:18:17
That Kennedy Hacksaw looks like a pretty cool wee machine
 
The use of hex bar is very clever, you can see it in action in the utube clip

Spareys "The amateurs lathe" has a few bits 'n bobs if you don't have it, including basic drawings.
 
Get a cheapo green fronted paperback version, you'll be glued to it.
I got a first edition then realised I was going to wreck it with the amount of use it was getting in my early lathe days.

Spareys book is pretty much the holy grail for a lathe newbie.

But I would use the 9" angle grinder for your job.
 
And it would take 5 minutes tops with a decent cutting disc setup.
ding ding ding ding ding...job sorted
The problemo is these things cant be done if you're in a flat at 9pm after being at work all day and you want to stay on good terms with your neighbours.

Gawd knows what my neighbours would think if they knew, the local council clergy are another problem too.

Thank you Mr Stub.
 
Tsk tsk tsk.
I suppose Frank Whittle had the same problems, genius and simplicity ridiculed by unbelievers...
 
Here's five feet of 45mm rebar (which is tough stuff) and a knobbly bit which I cut off tonight.
 
 
The blade had no broken teeth at the end of its work, the back gear works at about 50 beats a minute so the downside is it's no faster than a human, it just never tires out.
This job took about 3 hours.
 
The sneaky bit is the blade...it's the wrong way round...the handle end was the only bit with enough metal to set up a fast simple mechanism.
 
 
So the blade is actually being PULLED through the workpiece, and the far end is now the handle, which you use just like a normal hacksaw, except now the machine is doing all the sweaty work.
 
You simply push down on the cutting stroke as the machine works, you soon get into the rhythm.
 
At the end of the cut you stop the machine as the cut opens.
 
simples.
Thread: Here we go - parting off
24/12/2011 14:56:29
Try it with the backgear, then work your way up to higher speeds as your experience and confidence increases.
 
Us newbies can rarely just bolt and go where parting off is concerned.
 
I always part off from the rear side.
 
I also angle the tool slightly "uphill" to help with swarf clearance.
 
unless you have a machine with lots of power and stiffness parting off is yet another skill to be acquired.
 
With anything big I tend to put it on the hacksaw, less hassle.

I made a simple chopper upper out of a standard hacksaw which can be used with my backgear.
 
The Piccies are in my album.
 
Handy for chopping up big long bits, I keep my hand on the top of the hacksaw to stabilise it.
 
The 3jaw opens out to tighten on the hole in the "flywheel"
 
The bar has a couple of bearings and orange polyprop shims to adjust for a straighter cut.
 
Heath robinson stuff but it's chopped a load of 45mm rebar into manageable lengths with a single hacksaw blade.
