Has anyone attached tin to cubboard doors??

You can use wood glue, check it out http://www.gardenmyths.com/growing-clematis-from-seed/

Wood glue is made for porous materials which does not describe tin. Like many other solutions it will likely hold for a while but not likely to be permanent solution. Liquid Nails far better. Unless you have a shear tin snips are likely your best cutting tool. Use a straight edge of some kind to score a line with a sharp object. I would probably use a utility knife. If tin is thin enough multiple passes with that knife might be enough. More likely carefully follow your line with the snips. It may be a little difficult at first but with some practice it should turn out well.

Some finishing nails in the corners could also help secure the tin to the doors.

You might look at some antique pie safes for inspiration. Draw a line around the area, driil a hole in the corner of the hole in the door big enough to get a jig saw blade in there. Cut out the the rectangle. Sand and finish edge to match rest of cabinent. To make look like a pie safe, get a sheet of tin, draw design on tin, place on a piece of wood and use a nail and hammer to poke evenly spaced holes on the design line. Now you mount the tin on the inside of the cabinent either using little screws, or use thin wood trim to hold in place. We would age the tin with some type of acid wash. The cabinent would be painted with milk paint, and distressed. I would make a template for the hole size and the design for the tin to speed it up. You could also maybe try a drill to make the design holes. You can backlight the cabinent to make the design show at night. https://www.google.com/search?q=pictures+of+pie+safes&client=opera&hs=Ols&tbm=isch&tbo=u&source=univ&sa=X&ved=0ahUKEwi5z4Se19XTAhUW3GMKHW3WB_gQ7AkIwgE&biw=1366&bih=660

I used copper nails to attach the tin to the wood. You can also add a thin wood strip as a picture frame over the tin. If you have a dremel there is a bit for cutting metal that works good. Here are several videos and notice the tim is mounted on the backside of the doors so liquid nails would be fine. This method makes the cut less important. https://www.youtube.com/results?search_query=pie+safe+tin+patterns
