Wheel Replacement by: Kevin
Last year I had a Boardman & Wells wooden works clock rebuilt. I used a gentleman by the name of Donald Bruno at Torrington Clock Company. He did an excellent job repairing the escapement wheel and one other gear. Just thought you would like his contact info to replace your wheel. Hope this helps!!www.torringtonclockco.com
Wooden Strike Wheel by: Bill
I, personally do not know where to send you for this wheel. There are many different sizes and since I do not have too many occasions to repair these, when I do, I repair the old wheel by cutting new teeth where necessary, and gluing them in place.
I will leave this post here in case someone who works on wooden works more than I do can help you out.
