Singer 7-33 under restoration

Ha! ..in the very least...you sterilised it!!!

Always gives me the willies punching that much heat into cast iron. But I do like to warm a little to bleed out any oil in cast iron... before finding it later in the painting process.

Good to see the plate bed isn't stuffed

Maria,

Wow, just wow.  I'm amazed at the progress you have made!  When I saw the early pictures I thought "boat anchor".  Oh, me of little faith.

Jim - you are not the only one.  The guys at the Heritage Park are glad they didn't lay bets - today I got the last bolt undone that connected the upper and lower sections, and by the end of the day the top end was freely rotating with presser bar hopping along and needle bar moving as it should.  The lower mechanism is also rotational, but I have a bit of work to do cleaning up the con rods and the bearing rod is a mess...... but it's only been a week today since we pulled her out of the tank so I'm pretty happy.  I forgot my camera but I'll get pics at some point.

I'm amazed that you got it to turn over. Says a lot for the original design and build quality.

it does, doesn't it.  I think everyone here is amazed - I'm still doubtful I'll manage to get her sewing, that partly depends on whether the thread we wrecked can be rebuilt or not......I don't know the names of the parts but its the bearing shaft that holds the oscillating cam that in turn drives the hook.  Looked like it got water inside, so the bearing cap was fused on to the shaft and there was a ton of rust inside where the shaft is machined down for the oil reservoir.  We had to wind the whole thing out as one piece.  Put a lot of stress on the thread.  It is one of the few bits I needed help with, I simply wasn't strong enough.  The other end unwound no troubles!!

Have to admit - I did not expect this result!

Has anyone got thoughts on how to disassemble the hook?  The spring lever that holds the bobbin carrier  in place is stuck down.  I managed to take the carrier out by removing the tapered pin, to give more room to move, but the pin that holds the sprung part doesn't appear to go right through.  I wondered about grinding  in from the back to allow me to punch the pin out....... has anyone ever had to do this?

I managed to get the lower mechanism working yesterday, although it worked better turning the hand wheel the wrong way ..... I think the issue was there are no feed dog plates so the canvas just walks in a circle with the feed dogs when I turn the hand wheel properly down and away.

And today I managed to free up the shuttle retaining spring, so the hook is now complete and in place.
