Azul from California writes,
I was excited to discovery your motor rewiring series, but I receive got a model 99, which does non receive got the potted motor together with does involve a lite switch. The motor is mounted on the side, every bit seen below.
What I receive got is a Singer 99-13 (according to the Sandman Singer identifying page) from 1937 which I picked upwards off the street. It’s inward first-class cosmetic shape, but the wiring is inward bad cast together with downward to bare metallic inward parts (mostly due to my immature human pulling away the corroded/melted bits).
I create know how to solder, together with receive got access to the necessary tools together with materials (although non yet, alas, the Chapman screwdrivers). My immature human knows how to repair electrical stuff inward general, but does non receive got Singer-specific knowledge, although he’s enthusiastic and unworried almost this (“it’s a light” together with “it’s a motor,” he says). I did accept the machine to a local repair place, where they seemed to intend the wiring work non every bit good bad, they doubted that at that spot was internal harm within the motor, but of course of pedagogy would receive got to accept it apart to know for certain.
My enquiry is this: Do y'all intend your tutorial, along amongst full general principles of electrical repair, would move sufficient to move on this motor, although it’s non precisely the same type every bit the i inward your tutorial? Or are at that spot Singer specific issues that would brand y'all recommend instead taking it to a professional, to for illustration avoid electrocution :o), or messing upwards the machine further? I’m non certainly if you’re able to response that, but idea I’d ask.
First off, congratulations on the gratis 99! That's an awesome find.
Secondly, skilful on your immature human for pulling off the rotted wiring insulation. I’ve seen sellers completely ignore that, every bit if hoping it volition become away. As y'all tin see, the wiring tin easily come upwards into contact amongst the trunk of the machine, which is all metal. That’s bad intelligence if left untended.
To response your question: While electricity is evidently unsafe if non handled properly, at that spot is no Singer-specific number I tin intend of that would foreclose someone amongst cognition of “general principles of electrical repair” from correctly re-wiring your motor.
Because nosotros alive inward a province where people dear to sue each other, I intend I cannot just tell y'all to become ahead together with create it. But the "sideboard-mounted" motor on your 99 (I pose that inward quotes because “sideboard-mounted” is non an official term, it’s just what I telephone outcry upwards it) is a unproblematic together with basic universal motor, the same you'd respect on a 66, a 206, a 15-90, or a 201-3. The Featherweight 221 would also receive got a similar motor, amongst slightly less power. Bottom line: The principles of re-wiring yours would move the same every bit inward the potted motor tutorial, together with at the real to the lowest degree y'all would non receive got to bargain amongst the worm removal shown inward the potted motor tutorial (though y'all would all the same receive got to bargain amongst brushes, grease wicks, the washer on the armature shaft, et cetera). Your motor merely turns the pulley sticking out of it, which inward plow drives the belt, simplifying things a bit.
As long every bit y'all competently re-wire the machine inward the exact same configuration inward which it originally was, together with using the proper materials, I would intend you'd receive got no problem; but of course of pedagogy I create non receive got first-hand cognition of y'all together with your boyfriend's exact science levels.
Also move aware that if worse comes to worst, y'all tin purchase unproblematic replacement motors together with install those on your machine, should y'all non experience similar tackling the job. The argue I wrote the tutorial specifically for the potted motors is because those cannot move replaced amongst novel motors due to their odd blueprint (i.e. the agency that they jibe onto the machine).
If y'all create create upwards one's hear to purchase a novel motor, I recommend Sew-Classic sewing machine supplies. While I've never bought a replacement motor from them (I ever re-wire mine myself, to relieve coin together with because I respect it satisfying), I've bought many other parts from Sew-Classic. Jenny, the adult woman who runs the company, is knowledgeable, responsive via email inward illustration y'all don't know precisely what y'all need, together with has a (well-deserved) peachy reputation. She’s my go-to somebody when I demand parts.
If y'all create create upwards one's hear to tackle it yourself, retrieve to accept lots of photos every bit y'all disassemble the motor, together with so y'all receive got a reference for re-assembly. And a replacement motor is less than $25, which should accept around of the pressure level off.
Good luck amongst it,
