Re: fine (entomological or insect) pins

I think the problem is that the original formed head has been replaced with an epoxy bead head on all entomological pins.

Re: N7 Chassis Question

I think the point is that the spacing of the "Prototype" frame is immaterial. The model frame/chassis has to work as a 1ft to 304.8mm mechanism in its own right. Its representation to something 1:76.2 bigger is coincidental. In order to operate as a mechanism it must have appropriate toler...

Re: Track cleaning

I find these to be ideal as they are square and therefore rub along the top of the rail better.

Re: laser welding

A quick web search turned up one LW unit from China for £150. However, you need to wear an Arc Welding helmet when using it, which may reduce its usefulness for our needs.

Re: Bridge arch question

Actually it is NOT an ellipse it is either a 3 point arch or a 5 point arch.

Any decent practical geometry book will tell you haw to set it out.

The reason it's not an ellipse is because it would be a nightmare for the carpenters to make the false work.
