This scroll saw pattern is very easy to cut. There are very few interior cuts. Give this one a try.
Clockparts.com still has the insert shown in the picture for $3. These are decent inserts for the price. Click the link below to visit Clock Parts.
I also noticed that the bezel of the clock is easily removable. This allows it to be painted a different color with plastic paint. I'm going to give this a try tomorrow. I'll let you know how it goes.
