Thanks UWE and NIGEL, will follow your advice, I can see now the frames are getting better and better, if i get bored with making the frames or start having problems I will shift to just cutting out parts not putting them on the model, have to do some work room adjustments to make more room for the building slip to dry fit the frames. Don PS can UWE or NIGEL tell me where on the plans can i find some thickness of parts, probally my fault but can not find them in another post i listed parts that i had to assume thickness dimensions are they correct. THANKS FOR ALL THE HELP
