I know, lesson learned!

The 8 day main spring broke. It’s in a brass chamber with gears on the bottom part. It has a number #20 at the top. On the time piece it says.”Made in West Germany for Self-Thomas”…. How can I get this main spring? I have a mantel self-Thomas clock. The 8 day main spring broke. It’s in a brass chamber with gears on the bottom part. It has a number #20 at the top.

Use 0.0165 inch thick springs as discussed in the postings in this topic. Suppliers are given there, also see the "Clock Parts Links" in the right sidebar for clock parts suppliers. Hi Dan,

This is indeed the quarter strike movement. Both springs appear to be the same length. Thanks for the reply. This is indeed the quarter strike movement. Both springs appear to be the same length.

The 89L movement might have had a longer strike spring, if this is the quarter strike movement. You did the correct thing by keeping the longer thinner springs. Hi Dave,

I disassembled cleaned and reassembled the non-working one (has an 89L movement in it, bim-bam rods) and now it works great. When I bought the supplies (book, oil, mainspring letdown tool) I also bought a pair of mainsprings just in case. They were 3/4" x 0.0175" x 96" from Timesavers. I didn't use them because the originals (they're stamped ST on the loop) appeared okay when removed and cleaned. The originals measured 0.0155" thick though and when coiled next to the replacement, seems to have almost half again the number of turns. A lot of what I've read is that 3/4" x 0.018" x 96" is common for 8 day American clocks but thinner should be used. What about longer springs? What do you think I have in this clock? Did Seth Thomas put longer than 96" springs in their 89 movements? TIA, Dave (just getting into this as a hobby) Hi Bill,
