New Batch of Merritt’s Clock Mainsprings
August 27, 2007 . by BillMerritt’s Antiques has the P1496 mainspring in the red, orange and yellow box again! Last week I received 12 of them. I took two springs, measured them to be .0158 inches thick, cleaned and lubricated them, and installed them in a Seth Thomas 89C movement in an Adamantine mantel clock (my job no. 4396). These springs are perfect for this type of clock. The pendulum motion is good but not excessive.
