3D printed sleepers - alternatives.

Kelvin White All Messages By This Member #7651 开云体育 Hi John and all. 3D printing is all the rage at the moment, I’m old enough to remember when etched brass was all the rage then laser cut ply etc. Regardless a case can be made for using an appropriate model material to that being modelled.? So sleepers are wood, so why not use wood In the model, especially for spiked track. True spiked track, won’t take the rigours of exhibition use. In the past I have used Distressed and stained sleepers, stuck down in position. Then under the position of the flat bottom rail countersunk in, a small headed countersunk screw head flush with the top of the sleeper. The screw should not be wider than the width of the rail, so accurate positioning is required. A blob of solder on the screw head, and a large hot iron, will solder the rail to the screw head. Mark the the alignment of the second rail using a roller gauge. If you can’t find ?screws of the right diam use a bit of K&S brass rod, tapped into a interference hole through the sleeper and baseboard top. You can then use the protruding rod for electrical connections.? Just add cosmetic spikes ..... best regards Stay safe Stay sane Kelvin toggle quoted message Show quoted text On 22 Oct 2020, at 17:44, john.hjowett@... via groups.io <john.hjowett@...> wrote: ?Hi gang. I have never done this before so I'm just hoping I'm doing things right. ?I am modelling Irish 3ft / 21mm gauge but 3D printing all models either on my own printer or from the source in the Netherlands. The latter is more expensive but does a better job than I can manage so is appropriate for rolling stock. However getting Shapeways to print sleepers I reckon is beyond silly as it actually prototypical to have sleepers with a rough surface so I have been printing small panels, 7 sleepers long, complete with chairs. Once spray painted they met my aspirations and anyway it's crazy expensive. I then had a light bulb moment when I discovered that the County Donegal didn't use chairs so back to SketchUp to remove all the carefully crafted chairs and replace them with pairs of the smallest holes I could print which I then clean out with a 0.6mm drill. I am now working on a point and having a great time.

Several items from Worsley Works inc a Hudswell Clarke NZ diesel with chassis from Mark Clarke, 3D print Southwold Rwy wagons. Alphagraphics used to do card printed 3ft gauge models & Tyrconnel wagons, useful quickies or templates for scratch building.

Is anybody on this list modelling the Irish or IoM in 7mm on 21mm gauge track?? I want advise on available kits etc. thanks best regards Stay safe Stay sane Kelvin
