Re: 3D Software

Teebee should probably chime in on this, as I believe he has tried printing at home. In general, though, the more expensive a printer you buy, the higher quality the print, although there are other issues and exceptions to any rule. If you are looking to mass print relatively chunky parts where accu...

Re: 3D Software

I have used OnShape for a few models. When I was using it you could only have five parts active without open-sourcing them, so you either had to create a monolithic model or open-source the parts. It is also missing many advanced functions, so composite shapes (curves and so on) are difficult to mod...

Minimum Gauge Ore Bin Railway

Looking through the British Columbia Photo Archives I found an interesting Minimum Gauge tramway in the Queen Charlotte Islands (today known as the Haida Gwaii archipelago). The tramway was attached to the ore bunkers of the Ikeda Mine, supplied by a horse-drawn 36" gauge tramway. The Queen Cha...

Re: need help to ID this Hunslet

I am pretty certain the vendor is NEMALCO (Nelson Machinery Company) in Savona, BC, Canada. Just down the road from a city I used to live in.

Hi Simon. The crane comes in two pieces (base with pillar and crane boom/winch). The wheels are standard wheelsets gently snapped into place. Flush axle wheelsets would be best but you could cut, grind or file pointed axle wheelsets into flush wheelsets. The crane could be "disassembled" i...

As I have mentioned in the past, I have started using 3D printing for my personal Minimum Gauge models. I recently purchased a fully licenced copy of Solidworks 2016 for my design engineering contracting business and I am using this to generate new 3D models for printing on Shapeways as well. My pri...

Re: V-tipper wagons

The Blakesley Miniature Railway had some. Two photos can be seen on this page:

They look like they are built to their original gauge and don't have "pushed-in" wheels.

Re: New Shapeways Maker Material Report

I agree that there is a high expectation that is not yet matched by the reality. The reality is getting better all the time, however.

Re: Staining help

You can also try adding a very small amount of silver oil paint to the mix. This (in the correct proportions) can give you that silver effect often found on weathered driftwood. Play around with the proportions to get the color you want.

I think it varies quite a bit by the usage of the intended car and the locale where it was made. Heywood's wagon tops were 1.5" thick (1.5" x 15" material). Here in North America 5/4" ("Five-Quarter") stock (1.25" thick) was common for some types of cars while 2&qu...
