Wow, almost tempted to go back modelling LNWR lines! The Prestatyn station buildings are still extant, but are replicas becasue of the condition of the original wooden buildings.

However good the laser is, sometimes its better to use the right process for the application. So while I can cut fine details like 4mm windows, for strength and easier painting I've decide to etch the windows for a 4mm GWR Goods Shed commission I am working on.

0.4mm NS etch.

The 'letter box' under the windows is for the window sill and makes sure the windows are correctly aligned with the outer layers.

Flipping from one job to another while packing orders. I had a go with a different method of doing bricks on another commission. This time Shrewsbury signal box.

I think once painted properly this will be near perfect capture of the real building. One hopes anyway.

The walkways around the leaver room are very prominent so pushing my boundaries I made a little etch for this and the one of the box windows too.

The finial I've drawn and is ready to be 3d printed.

This build will truly be multi media. Not sure if I will make it a kit or not.

I'm always being asked if I could convert one of my most popular 7mm kits, the coal office in to 4mm. I've finally gotten around to it as someone waved some money my way :)

The little test build today.
Yup. I want one please in 4mm. Have you a price for the 4mm small Barmouth signalbox?
 
3d printing

I got a 3d printer sometime ago and recently I got it out of the box..

Having a little dabble in 3d software, I've settled with onshape. Its free, its full featured and its easy to use. So ticking all my boxes I've started designing odd bits. Gutting, Finials, fencing , door handles. Already I've a few bits and some of these will be available to buy via my website and some items are listed on Modelu3d as well.

I find tutorials a bit hard to stick with and find I learn best when I'm interested in what I'm trying to do. So in that tradition, I wanted to get to grips with the software, and I found a turntable drawing that had some interesting features that would keep me interested.

I chose the wheel first.

I had all the key dimensions and nothing was left for me to guess. So I drew the above drawing flat in my favourite 2d cad package Qcad. I really recommend this to anyone starting out in CAD. Its cheap (free) and fully featured and easy to use.

Once I had my DXF file drawn to full size. I imported this to onshape. Simply using the extrude tools, I made this in about five minutes.

Feeling that it was going in the right direction, I did the whole assembley for this section of the turntable.

So this represents about 30-45 minutes work at my novice level so I'm sure those of you who are expert can knock up this sort of thing much faster.

I've exported to a 3d printable file and I'll print these wheels out this evening.

So what is a "dead-eye" and why that name? See prototype drawing, RH edge. How is the axle/wheel interface lubricated?

I shall not be surprised if Tony (@Osgood) has the answers.

From the drawing a dead eye appears to be a bearing for the axle, probably lubricated with oil/grease. Dead eye because its only open on one side?
Looks just like the fixture that attaches the wheel to my wheelbarrow.
