RDF East Coast Chain Home 1/144th - Card was created by ross_mcneill
Decided to scratch build Pevensey Chain Home station in 1/144th scale circa July 1940

Used scratch build techniques similar to common N Gauge methods but with card stock, texture papers and foam board scenic bases.

Receiver Building, Standby Set House and Transmitter Building depicted are all "intermediate/final" versions blast and direct hit protected.

Receiver Tower is work in progress. The two wire frame dimension check models will be replaced with card versions similar to the front two. Maintenance access platforms, internal ladders and dipole aerial sets are still to be added from scratch build brass etch frets.

Impressive. Do you plan to incorporate them into a scale base?

I remember my attempts at building things out of brass angle. I soldered the first parts together but trying to add more unsoldered the first lot. Later I found lower melting point solder and better flux but by then I lost heart. The foam board is great to work with but I difficult to keep the cut square.

Space is the limiting factor.

The receiver block and the four towers will be incorporated into a 750mm square tile with the transmitter block and towers a similar but slightly longer linear tile.

Standby set house will remain stand alone but on 750mm tile to incorporate access road.

These three units plus the semidetached wardens house will complete the 1940 layout omitting the grass areas between. For exhibit they could be spaced to scale with grass mats between if room was available.

To show the development of the site into 1941 tiles for the buried reserve and associated towers will be added.

The blast walls are 5mm foamboard and I use these two cutters to get 90 degree cuts and rebate the corners for jointing.

Well worth the investment. I've used them for architect visualisation models for ages and can vouch for the precision and speed.

Final two models for this project will be 5mm/3mm foamboard internal floor plan/wall models of both the receiver and transmitter blocks.

Beauty of card for the 1/144th structures is that I can print off as many as I want at the cost of card stock and glue stick only.

Ross,

Thanks for the links those cutters would have solved all my bad cutting and wastage. I gave up modelling in the early eighties but with retirement approaching at the speed of an express train I might start up again. Will have to ditch the varifocals though as everything looks slightly curved through them!

It's surprising how large a 1/144th scale model actually turns out. I would still love to see a 1/72nd scale model of a full sized WW2 airfield and I'm surprised such an exhibit hasn't been made as it would be a great teaching aid and also a reminder of the layout and buildings used and I am aware that this will be huge to say the least!
