Hi Lisa, I’ve managed to find which magazine I saw the article in - it was the June 2013 Engineering in Miniature. Would anyone happen to have a copy would be willing to scan, before I contact EIM about back issues? Kind regards, Tom Hi, Tom I may be able to help, subject to a successful scan and being able to attach it to a PM/email/or even snail mail. You may recall that the author, Nigel Thompson, prefaced his article with references to Simon Bowditch's articles June - November 2009. I don't think I will have those but I do have Nigel's of 2013, two and a bit pages with colour photos. Give me a while to revive my old scanner (connected to an old PC!) and I'll let you know how it goes. With luck though you may get other offers. I'll come back to you. Bob

Roger - the video isn't being found. Hello Steve, Roger It doesn't work for me either but that's no great surprise because I often find that highlighted links within a text do not work by simply clicking on them. Sometimes though, holding down the right mouse button and Ctrl C/Ctrl V will put the link in the address bar, as it does in this case - there is the image but it does not come 'alive'. (There is however a short set of reduced images along the bottom). I thought it was just me but experience has taught me that such odd things do happen occasionally Bob

The Bristol Club need a certain minimum number of petitioners so the matter can be debated by the full Bristol Council rather than be determined by officers of the Council. So this is why signing the petition is important. Julian Thanks, Julian I've signed too, Bob (Somerset)

Sorry all. I somehow managed to miss the date of the original question. I remember the Colin Usher list but don't know if the itech.net.au list is the same.

I have bought a glanze 8mm parting off tool, replaceable tip type, for use on my Unimat 3. Rodger: A couple of thoughts from another Unimat user: 1. Chronos are currently offering a set of quickchange toolholders, quite expensive but you do get eight toolholders enabling you to have one each for different tools, and the toolholder holder(!) is height adjustable. The QCT height adjustment does not affect the tip angle. 2. Axminster have a rocker type toolpost, their catalogue code 600823 - but I imagine using the rocker for tool height adjustment will affect the cutter angle. You may care to check the recent discussion on the Yahoo Unimat 3 group. Bob

Some years ago I reported here that I have a stock of 2" x 2" slide glass left over from the days when I mounted my own 35mm colour film for projection. There were no takers and it is still available if anyone wants some. I'll dig it out and measure the thickness if that is critical. Bob I'd certainly be interested in knowing how thick they are please Bob.....i'd like to use scale glass for 4472, as close as possible to the prototype cheers Pete Hi Pete Sometimes I amaze myself, found them straightaway. My first measurement came out at 1.82mm. Closer examination revealed that I had two pieces clinging together (as they will) so call it 0.9mm/piece. I have one opened packet which measures 67.18mm so, say, 74 or 75 pieces. There are also two unopened packets so I guess 100 in each. Have as many as you like. No charge and I'll take care of the postage. Regards, Bob

People use microscope slide glass but a lot of that seems to be around 0.2mm and perhaps 1mm would be better.

not a bad idea, but I have no idea of the location of any professional honers, most of the engineering here in the S/W as long gone You might take a look at hamlinsengineering.co.uk/Their web page suggests a very competent organisation but I have no first hand knowledge of them. They are in Bridgwater, near the junction of the Bath and Bristol main roads. Bob

There is a book by Brian Hollingsworth, which I am told can be useful to those learning about driving trains. Not sure of the title, but something like "How to drive a steam locomotive", or similar. Spot on! First published 1979, reprinted 1987, 1988, Guild Publishing by arrangement with the Architectural Press Limited. Cannot see an ISBN number bp

Hi All - My marking out blue has over the months appeared to have lost its adhesive powers... Any thoughts and views on the matter would be most welcomed. - Reg A little bit of history: The "One and Only" - from www.clevedon-civic-society.org.uk/Spring2013.pdfAlthough Henry invented Engineers’ Blue it was his sons Les and Ken that started to market it in the 1920s. Ken was the one who did all the production work, manufacturing and distributing. The family lived at various addresses in the town including Hallam Road, Herbert Road and Madeira Road where Henry died. Production always took place in sheds of back gardens where they were living at the time. Bob

I had a root around B&Q I couldn't find any paraffin, nor BBQ lighting fluid. They had gel but I had misgivings about it Still listed on B&Q web page, 4 litre cans. Recently seen in the outdoor section with greenhouse equipment, heaters etc bp

(re Rolls Royce now produce jet engine parts this way - alan stepney.) I work for a company that deals very closely with said company and the biggest 3D printed jet engine assembly in the world. I need to be careful what i say about it (obviously its secret IP) but needless to say it is an amazing part made from Titanium. tolerances are Areospace so um's. as for what 3D printing can do for us well lots and lots... Some recent info at 3dprintingindustry.com/2015/02/19/rolls-royce-to-fly-largest-3d-printed-part-ever-flown/(I was looking for a report I thought was in a recent Telegraph newspaper or supplement but cannot now find it) bp

Gents, thanks for all your words of encouragement. Its the fct that NONE of these programmes will run on the laptop. Just a quick comment if I may, in my very limited experience I've found an ordinary laptop screen is rather too small. Not quite the same thing but I used to do a lot of desktop publishing and always found a big screen invaluable for layout work. bp

One piece of trivia is that at least two lathes were made in WW2 prison camps, one in Germany and one in... There is a long article about a lathe built in a prison camp in Guy Lautard's Machinist's Bedside Reader headed: "A SMALL LATHE BUILT IN A JAPANESE PRISON CAMP by R Bradley, A.M.I.C.E, ENGINEERING MAGAZINE, January 7, 1949 (Reprinted with permission)". This is in Guy's first (of three) Bedside Reader, pp 156-162 bp

Joan: you wrote "...where I get lost is when someone makes a reference of a particular part design by just citing its author". You won't find much detail like that in Hollingsworth. In passing, the WIKI article (cited earlier) and particularly the last reference therein (Station Road Steam) will give you just about as much. It's perhaps also worth mentioning that several of LBSC's designs have been reissued as books or booklets and, as well as Model Engineer, he also wrote for several other magazines. You could easily end up drowning in a sea of paper!
Regards, Bob

Julian, you often make references of designs or ways to do things according to "LBSC", "Don Young", "Martin Evans" and others. LBSC is an easy one, Joan, if you can find a copy of Brian Hollingsworth's 'LBSC' His Life and Locomotives. His creations are listed in a four page Appendix. The book is more of an historical survey than a technical description but the Appendix does include references to the dates and sources of the original sources. Bob

I think it is in Salisbury, New Brunswick, Canada as that is what is in the title of the clip lol trains up to 20,000+ tons are not uncommon in Canada Agreed. Google Earth/Maps shows the likely site: www.google.com/maps/@46.0324195,-65.0419908,218m/data=!3m1!1e3 No train! Or snow!! But the crossing lights are there if you check 'street view' - BP
