Try asking The SMEE?

JasonB,

What's a Weldon shank? Guessing it's plain with a large flat for a locking screw?

John

What an interesting thread, learned a few things here, even with several years milling experience. Never thought about drilling blind holes at the ends of a trough - slot. Also not thought about using a tube to blow swarf out. I have used a magnet to pick up swarf from slots. Never too old or too late to learn, even @70+!

Simon,

Very, very well done, fabulous looking model. Worthy of a prize at an ME exhibition, pity The Model Engineer Exhibition no longer exists as I think that it would have achieved a major prize. Congratulations

John

Just seen on news @ 1, views of world famous clocks 4 faces. I think that they look absolutely fabulous. Goodness knows how long it will be before my next sightseeing trip to the 'smoke' but will try to include BB in my itinerary.

Hi John,

Happy New Year

Time flies, could easily be 10 years ago that I bought the VFD and 3pfase motor kit from Newton Tesla, already wired up, just plug n go, as upgrade for my Myford S7. Straight forward fitting apart from the difficult access as lathe against shed walls. Wonderful piece of kit, wouldn't hesitate to get another if the need arise. Can thoroughly recommend it.

Brought to mind adverts in ME in I think, late 60s, of a small burner device with twin metal tubes for a small heating job. Think it was called "Valtock" or something like that.

Long, long time ago, my Father made up a small meths burner but can't now remember what he used it for. Base was circular (3" dia.??) thin brass sheet with a rising taper towards the middle where there was a round, vertical sided cup, about 1" dia?? X 1/2"?? high, which served as the meths receptical. No idea what that started life as, could possibly have been a light fitting. A large hex brass nut dropped over the top with it's shoulder at the top. A piece of tinplate cut from a can was soft soldered under the shoulder and a wick hole punched in the middle. Meths in the small 'tank' and a length of asbestos string threaded through the punched hole. What he used it for is a mystery after all these years, especially as he made up his own electric soldering iron. He didn't do model making in any shape or form - his hobby was rod and line sea fishing. Point I'm making is, how easy to make useful devices just looking at items and a bit of imagination.

Martin,

Material, given age of item, asbestos string???

John

One more; if you like small flat tins of oily fish for lunch, mackerel fillets, pilchards, sardines, save and wash the peel - lids and cut them up to size with an old pair of scissors. I also save the tins for small item storage.

Newspapers have Reporters, BBC has "News Correspondents."

Humph!

I think that they are biased, but that's MY opinion!

Remember a schoolteacher in a current affairs lesson saying that if you really want an idea of what actually happened, buy and read a minimum of 3 papers on the same subject.

Peter, are you talking about the firebox end of the superheater? My commercially supplied stainless one has a large ish rad on both tubes which appear to have been welded to a spear point.

1. Didn't realise that they take it in turn to provide the QS.

2. I have got a licence but object to the need for one.

My favourite method is to thread the stud about one pitch less than the thickness of the nut, grip plain shank in bench vice, wrench up tight, add drop loctite.

Quite agree with JasonB, should never use excessive force, no need. If in doubt about possible movement of the work, ensure, to start with, that table surface clean of any oil which could lubricate and if necessary, interpose a sheet of clean dry paper between the work and the table. Maybe also not attempt such hefty cuts that could induce movement.

Hi Michael

If you won't whinge about those horrors (the BBC), I will. They couldn't even do the Queen's speech, it was left to ITV Productions. Adding insult to injury, we get stung with a tax to watch it. "Licence" as far as I'm concerned is just a euphemism for tax and should be stopped immediately.

Must be my worst Christmas ever, seeing the Queen looking as if she was fighting back the tears, the phoned my desperately I'll pal back in hospital this afternoon for the umpteenth time. Never known anyone to have a 4th fight with cancer. Says he's had enough, don't want to fight anymore, wished today hadn't come, etc. So very difficult to find words of comfort under such circumstances.

Let's hope for a better New Year.

John

As a matter of interest, when I was in a fellow club members workshop in his house, spare double bedroom, I saw a model aircraft fuselage, nose down on floor and tail near ceiling, it was that big. I asked him how he got such a wonderful paint finish on it, dead smooth, looked like it was plastic. He said he warms the tin of paint and applies it hot so it runs, eliminating brush marks and leaves an even coating.

BSF and 2 BA used all over MLS7s until near the end when they were probably finding new supplies were getting expensive and Nottingham started using some metric almost certainly to keep costs down.

My own is an early 1970s model with no metric.

Quite agree with all that's been said above. Very well wrapped up including a stick of wood for stiffening. Joe is my go-to metal supplier.

Very well done, Joe and happy Xmas.

John

Nick,

I don't think so unless I'm missing something.

The rule appears to touch the corner of the cube at the 1" mark, and the 5" mark touches the caliper point. 5 - 1 = 4. ??????

John

By the time that the plastic sleepers are buggered by sunlight, my head will no longer ache, nor many of the other members!

Blimey, Andrew, is that the 'swing a cat' workshop?

Seriously, the "rags" of half melted plastic needn't really be removed, since there are just 3 slots about 1/4" wide and deep, so not much plastic to remove and even less to hang out of the ends of the slots. The sleepers in question are primarily cosmetic, since there are steel sleepers welded to the rails, safeguarding the gauge width. I don't think that there would be much rags to worry about and it's dark chocolate coloured plastic. Most people won't notice odd bits of plastic rags sticking out one end.

Many thanks to you all for your thoughts and opinions.

John

With the first diagram, I didn't actually try maths but thought "ball-park" - the height of a vertical radius above the flat top is approximately 2/3 of the total radius. Total radius is 1/2", (16/32) so 2/3 is about 10, or 5/16, so it seems my guess was quite close!
