Re: Protofour W iron units

I’ve used this system too, building about two dozen wagons more than 30 years ago using ordinary rubber band strips and MJT W irons. It does seem to work fairly reliably providing the same care is taken to ensure the units are aligned carefuly and secured squarely, as applies to any system. At the t...

Re: best insulation material in loco?

Polyimide film, such as Kapton tape, is widely used for both insulation and thermal protection in PCB production, especially in the aerospace industry. It was even used to plug a hole in the International Space Station! It is available in various widths and although a lot more expensive than PVC ins...

Re: 1970s street scenes in colour - full of modelling detail

An interesting topic! Colour rendering in film emulsions and it's variation is a complex subject, made more difficult by our own colour perception. Kodachrome was a fairly consistent emulsion by the 1970s but even so there was variation between batches - large users for commercial purpose (such as N...

Re: Working with cutting machines

Re: Working with cutting machines

Very encouraging results, Ralph. I took delivery of the Emblaser 2 about a year ago and was quite impressed with my initial experience, using MDF, despite the clunky Laserweb package. I have downloaded Lightburn but due to office space contraints have yet to get very far with it, however it looks to...

Re: Wheels for GWR 68xx Grange locos

Jim,

I think beauty is in eyes of the beholder! I find the Grange well-proportioned and balanced, more so than either a Manor or Hall. I prefer Churchward & Collett tenders to those that followed. And I find Dukes and Dukedogs the essence of graceful perfection... :o

Each to their own!

Re: First dabble in P4

I agree with Andrew - I usually use resistance soldering for these sort of details as well. I usually tin with 145 solder first, seems to hold better on small details because it forms a better fillet, possibly. But you do need to be careful how much power you use - practice with a similar piece of s...

Re: plastic chair systems not holding rails in slide chairs

Try using Loctite 480 - this is supposed to be ideal for use with ABS, and seems to do the job well. Keep it in the fridge as it's a little expensive IIRC, but mine is now three years old and still ok.
