Re: Adventures in the third dimension

At this level would the quality be sufficient to print something like a 4mm wagon buffer for example? Yes. The buffers on my recent SECR stock were printed on a Mars Pro. The surface finish is slightly better than I can get at Shapeways --- less residual texture --- but the holes for the buffer ram...

Re: Socially-distanced challenge: SER 27' close-coupled stock

27ft-handbrake.png The handbrake wheel was high on the end wall of the coach, driving a vertical shaft through bevel gears.

Re: Socially-distanced challenge: SER 27' close-coupled stock

The brake arrangements have been sorted out. The brake coaches have this:

All the other coaches have this:

I have products for both arrangements on Shapeways and will modify my model when the test-print for the new one comes back.

Larger-scale soldering


An example of soldering larger objects, outside the scope of model making. I thought it might bear on the soldering of boilers.

Re: LMS D1735 Brake Third

The overly thick side frames have been a problem for ages. I wish there were 3D printed ones that would glue to Bills excellent frames. What would the spec be here? Would people want a complete, printed side, or just the fittings to attach to a brass side? In my experience, a print can incorporate ...

Re: Coach Seating

Thanks Guy. I've spent the afternoon butchering the Ratio ones. First thing to do was reduce the height of them and then slim them down. If you say the Slater ones are fatter in the back cushion's they might not be any good. I'll slog away with the Ratio ones for this coach and get a pack of Slater...

Re: Coach Seating

Slaters do some described as "MR/GWR Coach Seats for non-corridor stock". I have a Slaters' pack stored away from way back and that is possibly this product. The seat backs are much flatter than the ratio mouldings and might actually fit into 3rd-class compartments. But the profile is so b...

Re: Socially-distanced challenge: SER 27' close-coupled stock

This project is now stalled by my inability to line coaches well and easily. SECR livery, with goldish lining on the edges of the mouldings, is not easy to do well. So far I have tried the following methods. Bow pen with dilute paint. It failed to draw a neat and thin line. Probably the pen I have, ...

Securing plastic roofs

In the past, I've had problems with plastic arc roofs on coaches and vans, specifically those provided pre-shaped in kits. The given curvature is rarely exactly right, and the spring in the plastic makes it hard to fix to the etched body. Bad attachment at the cantrails gives a wavy edge to the roof...

Re: Working sprung axleboxes...

As for the remaining challenges, I suspect it is correctly working door catches. (Working brakes and opening doors have been done.)[/quote]
Indeed. I would very much like to make a working cameo of a shipping coal-hoist, but there's not much point unless the wagon doors open at the right moment.

Re: Green screen background

Cycloramas in theatre are a potent source of headaches.

Re: Green screen background

If one were to do this successfully, two problems must be overcome. First, the movement in the background should not call attention to the fact that the foreground is frozen apart from the moving trains. One might enhance an empty, static scene --- perhaps the fells around the S&C or Dungeness m...
