Thread: Centre punch size
25/09/2011 18:16:43
OK silly question alert!
 
I want to buy a small centre punch at an online supplier. Thing is they are given in sizes ranging fron below 1/8" to over 1/4".
 
What I want to know is what that measurement is? Is it the tip or what??
Thread: Accurately marking centre line
24/09/2011 23:37:42
Nice one gents, thanks

Hi all, back at the engineering after the summer (devoted to other hobbies) I could do with a pointer on this:
 
How do I accurately mark a centre line down a very narrow piece of metal.
 
I have some 3/16 square bar and I need to drill a couple of holes on a centre line. Now clearly the half way point is 3/32, but its too small for my smallest square??

Hi all.
 
I'd like to advertise the fact that PEEMS are holding a 10th anniversary open weekend showing off many models, engines, traction engines and our railway.
 
To be held at the WRVS Hungate centre on Hungate in Pickering (right by Pickering Beck bridge) on Saturday and Sunday 1st and 2nd October.
 
See you there
Thread: Steam
26/02/2011 19:08:37
Its the smell. I love the smell of steam and oil all mixed up, Its unique.
26/02/2011 12:31:48
OK when I kicked this steam engine project off, I planned to run it on compressed air as I have a compressor handy.
 
However now I'm leaning more towards running it properly on steam. I have absolutely no idea where to start. How do I make a boiler and what do I run it on?
 
Can I get a plan for a boiler?

Whats lapping??
 
I made the piston first as it happens and then made the cylinder bore to the plan as I only had the one reamer (5/8")
 
I may yet make another piston as the rod is a tad short too.

Thread: Some thoughts on Model Engineering
24/02/2011 14:50:10

Hi Wolfie, I'll just add I don't think LBSC's work could be classed as any sort of a snobbery, in fact he challenged established ideas somewhat.
 
Regards Nick.
 
Sorry the last paragraph wasn't meant to apply to the LBSC one above it, rather to the 'snobbery' that many single types of modelling has for others. In the IPMS case, many aircraft modellers are utterly blind to anything else.
 
I am one of the rare ones. Because I build semi professionally I am open to hints and tips from any modelling discipline. For instance although I don't have much of an interest in model railways, I do look occasionally at model railway mags. Why? Cos they are bloody good at groundwork and buildings those lads!
 
I am using my lathe to reproduce diesel tanks in aluminium and a few other odds and sods. I resin cast odd parts too.

And for those of you who may think plastic modelling is easy go and look what happened when I was asked to build this....
 
 
24/02/2011 10:24:35
Others make adaptions to thier workshop machines and tools ect. and still class it as "model engineering"
 
Perhaps then the more accurate term then is "minature engineering". A small engine is as capable of doing work as a large engine.
 
Interesting. So is a model then a non- working static exhibit? Whereas model engineers are "making a working miniature of a full size prototype".
 
Does that then become a machine in its own right and therefore no longer a model??? "LBSC's notes, he didn't regard what he built as models, more over as live steam on a small scale" (Who or what is LBSC?)
 
I reckon its about time that model making snobbery, which we also have within IPMS, aircraft builders are by far the majority (about 80% of all modellers), is knocked on the head. Perhaps a UK Modellers Society. Welcoming model makers of all disciplines?

I was thinking earlier. Most model engineers have skills that are equivalent to full scale engineers, indeed many of you are or were full time engineers.
 
So what denotes a model engineer? Me for instance. I was a truck driver for 22 years then made a career change and nowadays I'm an IT engineer. Not a mechanical rod in sight!

However I did have a granddad who was a keen engineer as was his father (who I never knew) and his son, my uncle, who I also don't see much of for geographical reasons. But I have the bug.
 
Where did it start? Classical model engineers seem to make models of the machines that they or their contemporaries make. But being as machines as we know them haven't been around that long do we assume that model engineers started around 1800?
 
I don't know the answer to this, I am just theorising. Prior to the industrial revolution, there wasn't much in the way of machines, about the only man made thing that was worth modelling was the ship. And of course ship models have been around for many years.Far longer than model engineering.
 
I suspect I'm trying to reconcile modelling as I knew it up until a couple of years back with other disciplines. I started, along with many others of my generation with Airfix kits. On looking back I know that was because they were cheap and available and I didn't need anything more than a tube of glue, a handy kitchen table and a copy of the Yorkshire Post to keep mam off my back.

And so it went on. Today, 35 years later I command fees of up to £1000 to build models that are still based on plastic kits, and I can do this twice every 3 months, work it out. I am a member of the International Plastic Modellers Society (IPMS) and have been for years.
 
Last year at the worlds biggest IPMS model show, Scale Model World which fills three halls of the International Centre at Telford, the ship class was won by a wooden model. I had no problem with that, but quite a few did, note that the P in IPMS = Plastic!
 
And then I visited Sandown last December and expected to see nowt but steam engines. Now while I did see a lot, I was also impressed by the stand that had a whole load of coaches on. All wooden models, beautifully made.
 
So where does 'modelling' as I call what I do, and 'model engineering' meet or diverge.
 
I was at a model show on Sunday. In Huddersfield. A regional show but (and I hate to say this here) it made Sandown look like a garden party. The annual IPMS show is 20 times bigger than that. And we as plastic modellers are worried about the lack of youngsters in the hobby. You guys must be at your wits end.
 
I'm wondering whether we should drop the X in X modelling. Shouldn't we just all be model makers that make small versions of the machines that take our fancy whether working models or static models.
 
What do you reckon, in Roman times was the guy that made a minature chariot carved from wood any better than the lad that made one from clay?
 
OK I'm rambling now, over to you lot. Discuss

Hi chaps, now that North Yorkshires winter has finally let me back into the workshop, I've done a bit more. And I'm dead chuffed with this even if it is small stuff to you lot, so be gentle.
 
I was worried about tackling the cylinder casting as I really wasn't sure how to hold it to begin with, but after talking to someone at PEEMS (http://www.nrmodeltruck.co.uk/peems.html) at the Feb meeting I bit the bullet and went for it.
 
Using lathe tools and a reamer I reckon this is a success! The piston fits beautifully (although there doesn't seem to be much in the way of compression) and it moves up and down spot on even with the covers attached. It does bind slightly when I tighten the gland up, but I can open up the hole in the top of the gland a dab as there will be an O ring in the bottom.
 
I have to tell you its great when things like this come off, I have new confidence and all sorts!
 
Be gentle

Thread: Lathe and tap and dies for begiiner to purchase
23/02/2011 21:40:34
I bought a micro lathe sold under various different names by Axminster, Chester etc etc, for two reasons. One I'm not very rich and two I'm pushed for room.
 
So far I'm managing although adapting a vertical slide for milling has been a challenge.
 
I would like to upgrade though. At the moment my horizons aren't very broad so I don't feel the need to upgrade very far. Mind you I didn't think I'd need anything bigger than the one I had now year ago.

My problem with these things (as another beginner) that I can't find one that even remotely fits my minature lathe
Thread: Square peg in a square hole
04/02/2011 08:03:56
I need to make something to wind a clock thats lost its key, so quite small.
 
Actually on reflection I don't suppose it has to be blind... Mind you I don't have any files that small.

Ok heres one. How the hell do I drill a square hole??
 
A blind one too. OK I could see the method of putting a file through a round hole and filing it square but that ain't gonna work for a blind hole.

ME seems very railway engine orientated plan wise, and I'm not really interested in those so where do I find plans of other things.
 
I'm not sure what yet, just to be able to browse and see what takes my fancy. I have a couple of sets of stationary engine plans but theres got to be summat else?
Thread: Tram article
23/01/2011 19:32:40
From the point of view of a model maker rather than model engineer I'm really enjoying the tram article thats ongoing at the moment.
 
Superb build and very informative with lots of 'work in progress' photos. Its a complaint of mine in some of the modelling press that they spend too much space on photos of finished items rather than WIP photos. While I do like to see what my peers have been up to, more importantly I want to see how they did it.
 
A very inspirational article, it wouldn't really be my choice of subject but its certainly making my fingers itch!

"We have the same DIY supermarket feature as Richard - an OBI store opened in Arad two years ago, and on the shelves was one 7x12 chinese mini lathe (same as Clarke CM300) - its still there!."

Err how much are they asking for said lathe?
