My wife has some older mechanical sewing machines that she uses mainly for just the straight stitch they do. That and they are fast too, when she wants to hit the full go pedal [1200 stitches per minute].
The machines have a thread holder on them that allows the thread to come off the spool and not have an preload on it. It is held up by a collapsible rod similar to an antenna on a car. The piece that attaches the thread guide to the pole is plastic and with age it has hardened and broke.
I tried a zip tie but it ain't cuttin' it.
So I decided I needed to come up with another way of fixing it.
Settled on using some coupler nuts drilled out to slip onto the pole.
Drilled out on the drill press leaving a short amount at the end for the thread guide rod hole to go thru. I'll be able to get some short set screws to help hold that in as the coupler threads are still good to go.
All that's left is breaking the rest of the plastic off the thread guide rod. The only forseeable problem might be if the thread guide swivels too much now on the pole.
