Singer Schematics Similarities?

Thanks Darren...I'm sure you're right but can't resist trying just to see if it'll work.

To avoid the wear problems caused by bonded threads High Tenacity Polyester is an excellent alternative.

Where can I find more info about the high tenacity polyester...I'll be googling it but sometimes someone will have sources or links that can be difficult to find solely by using google. Thanks.

Amann Serafil is HT Polyester.

I was the one who mentioned "boat anchor" status.

The two potential issues with such an old machine are presser foot feed adjustment - which determines stitch length - and wear in the shuttle drive gears.

I'm not able to check for Bell Crank wear because I'm waiting for a replacement stitch adjustment screw with the gib and small square mounting bracket...but as soon as I get it I'll be able to run the machine and then check the presser foot for wear in the Bell Crank Lever by placing the presser foot lifter bar in the up (raised) position and checking to see if there is any movement in the foot...is that right? As far as checking for wear in the shuttle drive gears, those are located in the arm carrying the bobbin shuttle assembly, right ? Is there a way to check this for wear or is it just a matter of removing the plate covering the rack and pinion gears and visually examining them? What exactly will I be looking for? Will the wear be obvious or is there a way to check how badly worn the part in question is? (and what part am I looking at/for?) I understand that its important to invert the machine and note the position of the gears because by removing the plate covering the pinion and gears, they will fall out and the timing will be affected if the gears aren't put back exactly the way they came out.Thanks.
