(Which is a provocative title for a post about a sewing machine.)
Just for reference, the needle in the middle is the proper needle for a Model 12. The needle on the right is the one that was in the machine. Yikes. Shorter and with a much fatter base (with a flat shank, when the proper needle has a round shank), it was also about as broad as a tree trunk, and as sharp.
Needless to say, it was a much happier machine with the proper needle in. The horrific skipped stitches vanished pretty much almost immediately.
Several other issues did not. The biggest one is the tension. Model 12s have the
stupidest most primitive shuttle I’ve ever seen. The bobbin thread tension is controlled by poking the thread through a variable number of holes. Unfortunately, even the least number of hole-threading manageable seems to be too many, as the tension appears to be too high for the needle thread. Teeny little loops of thread on the underside. The situation did not improve significantly when I discovered that there was ANOTHER hole on the shuttle, forward of the other three, which was clogged completely with crud. I’m also having trouble winding the bobbin smoothly, so I don’t think that helps, either.
I’m not quite sure how to adjust the top tension, either—although perhaps I need to take the front off the head and see if it can be adjusted from the inside. That scares me, though, because a bunch of stuff is connected to the part that comes off and it shifts alarmingly when you take it off.
The belt is slipping. I shortened it a bit, but it’s still slipping, so I guess more shortening is in order. This, too, is scary.
Possibly related to the slipping belt, but I find the machine hard to treadle smoothly. It tends to klonk and reverse itself after a few treadles, especially as I try to go faster. There doesn’t quite seem to be the kind of easy rocking motion I am used to in other treadles (not that I am a particularly adept treadler, either). I’m not sure if this is just a feature of the more primitive mechanism, or if there’s anything actually wrong. At least it’s not squealing every motion anymore. I have oiled the snot out of it.
And, possibly worst, I can’t find a serial number to date it! It should, apparently, be on the bed at the base of the pillar. Probably right under all that red paint. /sigh.
On the up side, this machine probably hasn’t actually been used in my lifetime, and is almost certainly well over a century old (the Model 12s were produced from the 1860s to 1902). The stitch will be gorgeous if I can just get that damned tension right. I mean, even if I can’t, it’ll be awesome to have it usable for little demos, but wouldn’t it be grand to actually sew, oh, I dunno, my drawers on it?
BUT IT SEWS!
