That looks one big sheet of brass!! Is it cz120 and what thickness? - just out of interest.

Hi Dave
                 Thanks for the tip, will give it a try.

                                                                   Cheers David

 Hi Chris
               The 1/8" brass sheet is not CZ120. It is a semi hard brass of unknown spec, which has proved to be satisfactory in the past. The book suggests 3/16" for the plates to ensure stiffness of the frame. I have plans to modify the clocks design should my plates and frame need extra stiffness.

                                                              Cheers David

  Hi Guys
               When using the jigsaw to cut out the clock plates, the upward action of the blade lifted the paper template in places making it difficult to follow the line. I had to stop several times and make quick drying adhesive repairs, so I would not recommend the use of wallpaper paste.
 
                                                              Cheers David

Hi David,

I've used Pritt Stick for similar jobs. The paper (and Pritt Stick residue) comes off easily when soaked in water.

Cheers.

Phil.
