  1. I found I had to do that when assembling the wagon wheel sets I made using 3D printed centres and parallel journal axles. The main axle ends were square and sharp and could quite happily cut their own seat when press fitting them. Jim.
  2. I think I remember from a discussion on wheel tyre metals many years ago that mild steel gives the best adhesion. But I doubt that we should worry too much about adhesion in S scale with the shortish train lengths we tend to have. There could also have been a preference for suppliers to use mild steel since it is an easier material to machine than stainless steel. Jim. PS. I think the longest train I saw in S scale was a train of wagons behind a MET tank on a continuous layout I had at my previous house in Yate. The MET tank was a scratchbuilt insurance replacement (by Vic Green IIRC) for Alan Cruikshank's original which had been stolen off a stand at an exhibition. Les and Carole emptied their stock boxes to provide the load and I think there was in excess of thirty vehicles behind the loco.
  3. Same here. I emailed an order for sleepers over a week ago to be paid for by Paypal. I received an email acknowledging receipt and stating that my order would be processed, but since then, nothing. I've tried emailing with no response and I resent the order today to see what happens. Jim.
  4. You might have a problem with their minimum order quantities. I remember the SSMRS ordering a supply of Code 87 bullhead rail from Wintwire some years ago. We wanted 1000 yards of rail to match the order we had put out for injection moulded chairs, but had to accept nearly 2000 yards. The final amount that we had to take depended on the quantity of undrawn source material used and that was a fixed quantity. Jim.
  5. The non-professional one I use (Emblaser 1) uses GCode - the standard CNC code. Jim.
  6. The Glasgow show started in 1967. I remember because I had promised a layout for the first show, then had to disappear on a long training course in England during 1966 and assumed that organisers would accept that I could no longer supply the layout. Came back at the end of 1966 to find that the layout was still required and had to build it from scratch in about three months. :-) The first show was held in part of the McClellan Galleries in Sauchiehall Street and was crammed on the Saturday such that the Fire Brigade almost closed it down on safety grounds. Subsquent shows took a much larger area of the Galleries and still were extremely busy. I think I remember total attendancies of 20,000 plus. Jim.
  7. I dug out my copy of the manual as well and had a read through it. What jogged my memory was your mention of belt tensions and I had a read through the belt setup again and found that both X carriage bodies were not touching the frame at the bottom of their travel, with the right hand one being about 1.5mm away from touching. That would have put the X carriage at about the angle which would have given me the out of square error. So it was a bit of a fiddle to get the bottom belt re-tensioned to get the carriage ends both touching. Another test cut gave me a corner which was pretty well spot on. I'm not sure how long it might have been like this - whether I originally set it up wrongly or the belts have stretched a bit after seven years - probably the latter since I'm sure I would have set the belt tensions up properly when I built it. Jim.
  8. I've just set up my Emblaser 1 to do some cutting - it hasn't been used for over a year. :-) I'm doing some double sided etching and cutting and I'm setting up a guide to ensure accurate registration when I flip the MDF over. In setting up the guide, I used the Emblaser to cut a right angle corner based on (0,0) on a bit of MDF and I noticed that the cut right angle was not at 90 degrees, with the angle probably nearer 91 - 92 degrees. I can't remember if this is a problem that can be adjusted and whether that is mechanical or by programming the control board. Anyone remember what the adjustment procedure might be. I have a faint memory that I might have done this before. :-) I went looking for the Darkly Labs forum but that seems to have disappeared with only a list of old topics remaining. Jim.
  9. Basically, at the top of Buchanan Street, and quite close to Queen Street station. It was a short walk between the two stations. https://maps.nls.uk/geo/explore/#zoom=15.9&lat=55.86566&lon=-4.25100&layers=168&b=1 Jim.
  10. Continuing on this thread, I purchased some of the 2mm steel rod from M-Machine and got it yesterday. I've had a chance to check it over and it is actually 1.95mm diameter measured with my micrometer. It's also not dead straight, probably been unwound from a coil and roughly straightened. But would probably be OK for short lengths like wagon axles, especially if you machine a wheel seat at the same time as the parallel journal. It machines very well with an HSS tool in the Cowells. Ordering from M-machine is a bit old style - you email them an order, they email you back to say the order is OK and can you phone them with you bank card details., A very pleasant lady took my details on the phone call and my order arrived the next day. One of the reasonably priced sources of 2mm (exactly) straight shaft is from the Far East via Ebay from an advert such as this https://www.ebay.co.uk/itm/325232156039?var=514121653272&hash=item4bb958dd87:g:TdoAAOSw3qhiquGl&amdata=enc%3AAQAIAAAA8HoO0HiN495fjbrdE6RXTwyGwolNnO7Zw%2FjYSRPpZKRPM%2BsO2W7hEaUzwux2ZTucPVtLEvNy1z4kcaZCJ83i8GGjoQEKzivLyPpERH1RS4r54ZFF0y%2F2wrWGQS4F7kHVAgV0bsbTD3a4wlTenAujPUPevCCnMW7AWQxM93RwYZ04SaO06u8mjRGzb9%2FC%2BESYrB33o5e68unWHxrryeq4DXS5ZHjda%2BBSHuDRXZbBkvgiti77hxkErZrgXn5shHtDyeCwNc8Xf%2FxAtGOTnpb7H0f4Qqr1CYNaNgwxo8o6hJCZ%2B8h1I1pEHOu9S2OVTxl0RA%3D%3D|tkp%3ABk9SR9Sl1PqrYg The material I've received doesn't machine as well as the EN1A material from M-Machine or MK Metals. I wondered where the 1.95mm rod (M-Machine) of the 1.9mm rod (MK Metals) could have come from since there is no equivalent SWG size, but 5/64ths Imperial is fairly close to both. Jim.
  11. Just picked this up on Western Thunder https://www.westernthunder.co.uk/threads/new-4mm-kits.11874/post-279493 Jim.
  12. The British film industry relied on Red Star to get film negative (rushes) to London for processing. All the major negative processing laboratories were in London - Ranks, Technicolor, Metrocolor, etc. When going on location for filming, one of the first jobs of a camera crew was to establsh the nearest Red Star office. There was also the return service from London to the various regional centres of the BBC and ITV stations. All the laboratories had small fleets of vans continually attending all the major terminii in London from early evening till early morning. The beauty of the system was that it worked from all over the UK wherever there was a railway station with Red Star handling - even from Wick or Thurso although packages might take more than a day from there. It actually worked very well and there were only occasional problems. Jim.
  13. Just to continue the wagon axle topic of a week or two ago, I was pointed to another supplier on the Model Engineer forum... http://www.m-machine-metals.co.uk/downloads/Metals catalogue.pdf ...and on Page 66 of their catalogue is 2mm diameter EN1A steel rod. I haven't bought any of this product but the supplier has a good reputation on the ME forum so hopefully it is actually 2mm diameter and not 1.9mm diameter as is the rod from MK Metals. Jim.
  14. I use a hand reamer to finish off the axle bores in driving wheels. The hand reamer has a slow taper on the end and I only enter the reamer from the rear of the wheels until the full diameter is only cut for about 1mm and the rest of the bore toward the front of the wheel is still the taper of the reamer. This means that axles can be fitted into the 1mm parallel section then the wheels can have a gentle press for the axle to start catching the taper. You can now tweek the quartering until all is running well then the wheels can be fully pressed onto the taper. It's also an easy way to get a nice press fit. Before I did wheels this way it used to be real fiddle to get a nice push fit in a wheel bore that didn't need a four inch vice and a pipe extension on the handle. :-) Jim
  15. He has just started a two week holiday, so I wouldn't expect him to be back until about 10th July. Jim.
