Starting the Linkspan winding machine house building tonight. This will take more than an evening to complete. My styrene I beam arrived today so could get on with it. Firstly I started with the housing base structure which will eventually stand on legs above the Linkspan bridges. 

(first stage - styrene beam structure) 

Once I had finished with this I started on the housing itself made from Wills corrugated plastic sheet. 

(progress on the upper housing) 

Next will be a removable roof. I'd like to fixing Led lighting to the Linkspan structure and the housing will be a good place to hide wiring but will need access every now and again. Following the roof I will construct a walkway around the outside of the housing out of thin balsa. Something for the weekend. 

(where the structure will sit or be it on angled stilts once the winding house is complete) 

That's it for today - thanks for reading
