Thanks - i did open up the mainspring casing, and although I did not remove it yet, it appears to be intact. It is hook onto the outer edge of the casing, but the arbor (the peg on the center shaft) does not seem to be catching on the inner spring hole (which appears to be intact as well, no breaks). Could the peg/arbor on the center shaft be too worn to catch? Is there anything I can do about that? Or do I just replace the spring - or the entire unit (casing and spring)? I feel like I should be able to figure this out, I can see all the components, just don't know why it won't engage the spring! If you can remove the MS arbor from the barrel & spring, you should be able to see if the arbor hook is still there. If it is, you can bend the end of the MS with a pair of needle nose pliers so it will reengage with the arbor hook. You may have to undercut the arbor hook with a file so the MS will catch. BillF

On my Standard A the arbor hook on the spindle was very worn from a broken spring, so even the new spring did not catch. Looking through old catalogs I found that the arbor hook is not part of the spindle, but more like a thick pin that goes all the way through. I was successful carefully pushing it a bit out with a hammer and pin driver. After that the spring caught not problem and has been working ever since. Not sure if it's the same in your machine, but worth a try. Good luck. Andreas

When you guys refer to "thumping," is this a continual thumping noise? My D after a few min of playing and out of no where (scares me every time) is making a loud knocking sound. It's brief ...but really loud. Is this what your referring too?
