Hayfields 7mm 3D Printed Turnouts

[Hayfield1]

I thought you had a 3D printer!!!!!!!!

I do but I rely on others doing the CAD.. Downloading a 3D Templot file is child's play. However CAD design is another world, far beyond my pay grads

Now if someone else has the skills something about 2.5" tall and 3"/4" wide to hold shorter tools (Jewelers screw drivers) would be useful

I might even buy a third to hold my needle and 6" files

Back to modelling, I found some Lcut 7mm scale slates for the lever frame's roof



Just the ridge tiles to make and painting to finish

As well as putting removable end stops I have started to prepare for adding some ground work opposite the platform. The idea being to show 3D printed track in a scenic setting on half of the board, in the hope fold can not only see it running but also how it blends into the scenery

The view through the lever frame cabin



The weathering is starting on the scenic section

This is the initial stage of adding a bit of extra scenery. Firstly a layer of DAS on top of wet PVA. Next up will be a covering of plaster bandage (hoping it will prevent cracking. Then the top layer of DAS will be added

Ages since I built any scenery and enjoying something other than track and stock building

John,

I cannot understand anyone using plaster bandage. It’s messy, expensive, heavy and fragile.

I’d suggest ripped green paper towels (or newspaper) and diluted PVA (possibly with added brown acrylic paint or powder paint), over woven strips of thin greyboard. Greyboard is what Cornflake packets are made from.

Cheap, robust, lightweight, and easy to change.

you might give it a try?

best
Simon

Thank you for your advice and concern, I have obviously not fully explained that it will be a single layer between 2 layers of DAS.

I am using it to reinforce the DAS, the idea is the mesh/fibers in the towel reinforces the DAS from cracking during transit. No need for any framework as the height is only a few mm. My thought process is that as the baseboard is made from lightweight 5mm ply a length of 2' unsupported clay would crack when moved due to lightweight construction

As for cost, its NIL. The plaster bandage came in a job lot which ended up not costing much and as the bandage was a small part of the lot its basically a freebie, especially as it will be only a few inches of the roll.

I could have used one of those car repair metal meshes (which also came in a lot) but I will use it for something more substantial. Anyway its also a test bed for scenic ideas

Thanks again for your sensible advice which I would usually follow

John

Manilla envelopes (from the taxman!) work well as a newspaper substitute, a little stronger and the right colour.

Not sure about using DAS, it may crack anyway especially if exposed to humidity and cold, at least that's my experiennce.
