Something of a Freudian statement of social status at that time, methinks! CJI.

....... and since no-one can prove it's wrong - a rare chance to please yourself! CJI.

Not how I read it - it said that orders were coming in so fast that the overall number outstanding had hardly changed. Not the same thing at all! Patience is a virtue! CJI.

Nu Cast 2021 Pannier - Construction
John Isherwood replied to Erudhalion's topic in Kitbuilding & Scratchbuilding
You may well find it easier to remove the bulk of the whitemetal from the individual components BEFORE soldering them together; then finish off with a coarse file after soldering. CJI. -
Using Mobile phone only to log in to Doctor
John Isherwood replied to melmerby's topic in Wheeltappers
Fine - if you have half an hour plus to listen to "We do value your call; you are number 99 in the queue", followed by inane electro-music. CJI. -
New tooling - BR Standard 2MT 2-6-0 2MT 78xxx
John Isherwood replied to Graham_Muz's topic in Hornby
The 'tender side supports' are, in fact, ventilators for the water tank. CJI. -
Railmatch paint for MK1 BR coach roof
John Isherwood replied to j_fixer's topic in Weathering, Painting & Transfers
Whatever colour a coach roof was painted, it soon became a mucky shade of grey - and that shade varied greatly between individual coaches. So - if the coach had been recently painted, the roof would have been a relatively light shade; it would get darker as time progressed. So - it matters very little what shade of grey you use. CJI. -
Given the currents that are being talked about with DCC, I would have thought that a direct electrical connection between plunger and lead - ie. bypassing the spring - would be essential. Better still, for future models, avoid plunger pickups altogether. CJI.

Modelling mojo and state of mind
John Isherwood replied to Coldgunner's topic in Modelling musings & miscellany
Originally 2/- (10p). CJI. -
That's OK - I don't expect that you will be buying it! CJI.

At my mid-70s, that is a spring chicken. As to keeping up with the times, I trust the mechanical strength of a machine screw against magnetism every time! CJI.

Drill a hole the diameter of the distance across the flats of the nut in the false ceiling. Press the nut into the hole with a vice. Drill a clearance holes for the screw thread in two squares of plastic card, and stick one on each side of the ceiling nut. The nut is now trapped and can't rotate; furthermore, the lower clearance hole is ideal for locating the end of the screw into the nut - not easy when peering through a coach window. .... speaking of which - how close do you observe your coaches for you to be able to see the screws? At normal viewing distance, if visible at all, they might resemble a standing passenger. CJI.

Sealing Water Slide Transfers
John Isherwood replied to chipbury's topic in Weathering, Painting & Transfers
If transfers are sealed with Johnsons floor lacquer; (Klear, or whatever their current marketing brand is); Testors Dullcote - if you have it - should have no ill-effects. CJI. -
Indeed it does - I was quite happy to copy Tri-ang when Kirk kits came along. I adapted the method for my Kitmaster Blue Pullman, wherby the roof is detachable from separate body / chassis and interior assemblies. The false ceiling greatly stabilised the flimsy, flexible roof moulding, and created a ledge which supported the equally flexible sides. In both cases, the assembled bodies are remarkably rigid and robust. CJI.

I have found it quite easy to arrange my kitbuilt coaches such that the body is detachable from the chassis. Three long screws up through the floor into a false ceiling, as Tri-ang did many moons ago. CJI.

Current steam loco kit construction
John Isherwood replied to Jeff Smith's topic in Modelling musings & miscellany
My (secondhand) experience of 3D printing is that the technology IS capable of producing no-prep models. That said, the sophistication of the printer and, critically, the skill and experience of the operator, are the major determinants of the standard of the finished model. This is to be expected; after all, one would not expect a beginner to produce a perfect etched kit model. 3D printing is merely a new means of producing a model; albeit one with great potential, given practice and patience.

Current steam loco kit construction
John Isherwood replied to Jeff Smith's topic in Modelling musings & miscellany
If you wish to see the potential of 3D printing, look at IronMink's free-to-download design files on Thingiverse. When printed, just fit the buffers, wheels and couplings and place on the track; weighting and painting are optional but desirable additions. Note - zero prep. (sanding), beyond removal of supports, is required. CJI. -
Neil's SDJR 3D Prints
John Isherwood replied to neilkirby's topic in 3D Printing, Laser Cutting, CAD & CNC
Neil, So - to recap - is the Hornby 88DS chassis a goer for the S&DJR version and, if so, is that version of the body available to buy from you? John Isherwood. -
Spot on - with the removable section cast in / machined from the densest metal commercially viable. John Isherwood.

I attempted to assemble frames with separate hornguides, and I would describe myself as having more limited skills. The chassis is still incomplete, and will be replaced by a rigid version. I cannot, for the life of me, see why a person with limited skills would try and assemble equalised or sprung frames. CJI.
-
If 'cheating' produces a loco that runs as freely as the prototype, so be it! Of course, if track-laying is suspect, some may find it necessary to have wobbly wheels ...... ? CJI.

That is the precise point that I was making! I do not regard verifying the accuracy of a set of rods as a necessary function of a frame jig; that can be done with some drill shanks. If you can't get the rod holes to line up, don't even bother to get the frame jig out of the drawer. To my mind, the purpose of a frame jig is to get all of the axles perpendicular to the frames, and in the same plane. The Poppy jig does this to perfection, time after time - and it's MUCH cheaper than the more complex, metal jigs. CJI.
