Featherweight Guy: Gear mesh update! HD 720p

Following up on the discussion about gear mesh in the Prepping for Paint video, Featherweight Guy demonstrates the pattern with which the gear teeth meet and explains why we don't need to worry about returning to the exact same tooth-to-tooth configuration.

In automobile rear ends you have to worry about lash which is the "slop" or looseness between the gears - I believe this is all that needs to be done to these gears- Being an old guy I've lapped a lot of valves in old engines which should be about the same for these sewing machines. You are doing a great service for all the vintage sewing machine addicts. Thanks

Thanks, Bill. Like you, I’ve had auto rear ends and trannies and engines apart. Lots of clocks, too. Gear trains all work pretty much the same way.

Lovely diagnostics here, Bill - and thank you for the update! For a little while I was thinking 'Surely Sharpie don't make 20-odd different coloured markers!' This has got me to thinking, though, since you did find those two convenient 'not for matching purposes' marks on the gears in your last video whether, before disassembly, there would be an easy way to add one's own. Because it really is quite a good idea... Just a wee dot of paint, perhaps, applied with the end of a matchstick or toothpick if there's not a very fine brush handy? I'm interested to hear what your 'final findings' are after you put these machines back together and test them! :-)

Thank you, Megan. Yes, paint would work for marking. If I were going to mark the gears (I don’t believe it’s needed at this point) I would use the pointer tool you see in the video to make scratch marks. It has a hardened tip that should be able to scratch the hard alloy used for the gears.
