Re: The Station Building

As Tim has mentioned the Peco 2mm sheet I hope he won't mind my reproducing one of his pictures of Burnham, showing the box on a platform faced with this material, and edged with individual bricks (individually picked out in varying shades, oh my!) I recommend this material.

Pushed the boat out with 1st class tickets @ £4 supplement each way and saved over £63 - perhaps not so good as my £5.15 fare So'ton -> Highbridge after the Eastleigh show but not too dusty all the same. <edit> Perhaps we shoul...

Hello Steve - yes, planning to get to Expo, and had already hoped we might meet up. Which day are you going? Saturday is better for me as I can't get a Bracknell arrival earlier than 11.44 on Sunday (also Saturday gives me a convenient through train from Highbridge to Reading). Subject to that, I ca...

Re: How do you cut sections of hypodermic needle?

In my recollection -- I wish I'd had the prescience to photograph such things fifty years ago! -- NBR and CR arrangements had the stretcher bar / tiebar extended through the stock rails on each side (I think two stretchers, one extended on each side). I don't recall seeing a heel plate. But I suspe...

Many thanks for your replies so far, from which it seems that nobody has experience they can report of home concoctions of wood stain.

Any experience with home made wood stain?

I've been trying to find an acceptable finish for my stock of ply sleepers, but have been deeply unimpressed by the results obtained from wood dyes. I've tried Blackfriars Dark Jacobean dye (which is the closest to a black dye as I have been able to find in my part of Somerset), but I end up with an...

Re: How do you cut sections of hypodermic needle?

I can see such an arrangement might be acceptable if the Exactoscale cast fishplate pair is used, but I fear that the thinness of the Colin Waite etched plates might well give trouble in the long run. Another reason I have for proposing a wire pivot for the switch is that it provides an attachment p...

Re: How do you cut sections of hypodermic needle?

When referring to cutting slices of tube, I was thinking in terms of stainless steel hypodermic tubing. For a short production run of thin-walled brass slices I would be happy to adopt the 'rolling under a knife' technique. But would this work with stainless? For bigger production runs and with thic...

Re: How do you cut sections of hypodermic needle?

Many thanks for all your contributions. Within reason, the tube wall can be as thick as is necessary to obtain the necessary stiffness since it will be out of sight below ground level. If need be I could bore and turn suitable tubes, but was aiming to save time and work by buying in tube of suitable...

Re: Drilling holes in round rod/wire?

I think you stand a good chance of success with the drill press you describe. I used the word 'sensitive' with the intention of excluding some of the devices I have seen that are intended to convert a power drill into a vertical drilling machine - sensitive they are not! Ready cut strip is exactly t...

I am contemplating the construction of a batch of turnout operating units having some similarities to the Studiolith design. The stretchers will be driven by an escapement mechanism beneath the baseboard, and I plan to connect the switch tongues to the stretchers by means of wire 'droppers' attached...

Re: Drilling holes in round rod/wire?

I would think in terms of constructing a drilling jig for this, particularly if you need to repeat the operation. I've attached a cross-section of such a jig that should be straightforward to fabricate from strip material. Drilling Jig X-section.jpg The advantage of this is that you don't need to fi...

The Mossie can lay claim to being the first multi-role combat aircraft too. The Canberra was developed to a spec for a Mosquito replacement, and the search for a Canberra replacement led to TSR-2 and thence the Tornado.

Re: Gluing wood

Terry's memories of using scotch glue are much the same as my own, also in 1950's school woodworking classes - our headmaster taught the subject as an 'extra', though I don't think he would treat my subsequent efforts as much of a testimonial to his teaching skills. I think we had a thermostat-contr...

Lindsay, I see you're the proud possessor of an original Unimat 3 rather than one of the Taiwanese clones, and I also see a bolt protruding from the mounting point of the vertical milling/drilling column. This suggests that you may have such a column and milling/drilling head - if you haven't I can'...

Re: Society CCU dimensions

I have a 9' WB example which I have measured to be 22.9mm (+0/-.1mm) between outer frames, and 24mm (+.1/-0mm) over frames. The outside measurement has possibly been affected by the remains of a layer of adhesive for securing cosmetic sides, but not by much.

Just to demonstrate that there were exceptions that would prove pretty well any rule, the layout at Burnham-on-Sea had some fairly bizarre interlocking arrangements.

Re: FPL interlocking

To my very limited knowledge it is customary for the FPL lever to be interlocked in the frame with the lever for the points that it bolts. In the majority of cases the lock plunger stands out when its related lever stands normal in the frame, so the usual sequence is to work the points and then the ...
