Yes, I have built one of Clayton Boyer's clocks. Just this spring he had the plans for a wooden gear clock in the issue of "Scroll Saw" magazine that I built. And I am planning on making another one this winter I hope.
Don't be afraid of the wheels (gears) they are not too bad to cut.
Do read ALL of the instructions and follow them using the proper woods and parts. Short cuts don't help. DAMHIK
The hardest part for me was rounding up all the extra (non wooden) parts and pieces. (Especially getting the weigh and cord as indicated.)
I spent about a day cutting all the wooden parts, three days shopping and buying the non wooden pieces, two days on assembly, two weeks getting everything to work all together at once and two months timing it.
It was fun though. And it is setting in my shop ticking away as I type this. Remembering to wind it everyday sometime slips my mind though.
Mine has given me some trouble as far as breaking but, not too bad. I just recently had to re build the winding mechanism due to a plywood delamination. (re-gluing didn't work)
Don't be afraid of it. Just take your time and have fun . It is very rewarding when you get it running and hear that "TICK TICK TICK".
