Thanks for the response.
I am ready to go but cutting the plate is a bit of a pain. I have just wasted a plate with a poor guillotine. I am going to try the stanley knife option on the wated plate as well just to see if I can get it right. I know that some people use hand tin shears but I guess that would only work for small plates. I am looking around for a decent weight guillotine or workshop metal shears. You can get them on ebay. Good luck with the experiments. The UV unit I am using in my print workshop also has a vacuum frame built in so it is easy to use.
