This clock stands over 10 inches tall and should make a nice presentation.
Warning I have not made a prototype of this clock yet. The pattern is free as is. I am waiting for the clock insert to go into the workshop and cut the pattern. I will make a video of the cut and assembly as soon I get the clock.
The link to the free scroll saw pattern follows.
Visit Clockparts.com to purchase the clock insert. You need the 3 1/2 inch insert.
