... lot over the years so it could be that the Barry slips existed at one time, to be replaced by "proper" slips at a later date. I'll also dig out my 1963 Constructors which has a series on the I.o.W railways. Jim.

One does show the throat tandem but the slips( if indeed they are ... ) are rather indistinct. The pictures are quite early with wagons lettered as 'I W R' in some pictures. Rob P.S.

... the measurement so that a readily available measure was available. The actual size should have been 0.17" or 0.44mm. I've attached the first page of the article to show the authors' arguments. Also, if I remember at the time, modellers in other scales would not accept the MRSG dimensions for the scales which had been extrapolated from the P4 compromises. I know that was the case for S scale and Scale7. You can gather the flavour of the time from the heading to the article Jim.

... It is many years now since the tinned steel rivets were available from Studiolith Ltd. The rivets from the EMGS or Scalefour Society are copper or brass. Measuring some 20-year-old Vero pins, the head thickness is 0.6mm. The required thickness would be 0.58mm to represent the base of chair castings in 4mm/ft scale (1.3/4" thick). The head diameter is 1.8mm. This is less than the 2mm Brook-Smith rivets, so makes fitting half-chairs a bit easier. F6319596-01.jpg I have ordered some new Vero pins to measure current production. I can see that using bits of scrap kit fret or 0.5mm copper clad is cheaper, and doesn't require the drilling of holes. But it is surely difficult to cut them small enough and locate them accurately below the rail centre? Fitting of cosmetic half-chairs is dead easy if the rivets are in the right place -- just cut the chair in half, push it against the rail, flood with solvent*. And a real pain if they ...

... Templot can print a drilling template for that: 2_220711_090000000.png The rivets are tubular, and clenched over underneath to fix them. Ideally with a proper press tool, but many folks simply bash them with a small hammer, supporting the head in a washer to prevent crushing it into the plywood. You may see this method described as the Brook-Smith process, after the late Joe Brook Smith who invented it about 60 years ago. An alternative, also requiring 1mm holes, is to use electronics Vero pins: 2_020948_350000000.jpg F6319596-01.jpg These are a push fit, having ribs under the head, so need trimming underneath rather than clenching. They work great in copper-clad, but may not hold very firm in plywood. However, if you then fit cosmetic half-chairs round them with Loctite, that would provide sufficient strength. The advantage of Vero pins over rivets is that the head is smaller (1.6mm dia.), so making the positioning of them less critical when fitting the half-chairs over them. They are also ready tinned ...
