in world wide manufacturing co. it is common place, when the major plant stops producing a item or part. to send the die to make this to a lesser plant and star over. targeting sales in that area of the world. Then the new plant ( user) would combine pieces to make a newer style machine,

as with Volkswagen and there VW Buses made in Brazil. look at the very last VW made which was last year.. it's 2015 model year. but it's a combination of a 60's model and a 70's model, same thing took place with there south africain models

So, if it were in the modern "dog world" it would be a "designer breed." Now babies may be composed of three parent's DNA, so your machine must be a special breed!

I wonder if Singer sourced their modern 15s from the same plant making the Sewmaster machines. That would help explain how this issue got as confused as it is. Half or more of the parts on your Sewmaster may have made with the exact same machines and tooling as the parts found on a machine that was actually authorized by Singer.

To me your Sewmaster is like a 15 clone with the top tension moved to the front. The bottom half of the machine and the stitch regulator are certainly based on a model 15.

rodney did you notice the take up lever. I'll post a photo of what behind the face plate

on parts interchanging. on this machine there was a problem of it changing stitch length, and the lever not moving, plus ever once in a while it would bind. I found that in the column at the stitch length lever/rod. and at the slider, the square pivot ( bearing ? ) would try to walk out of the channel it slides in. at that point the bearing ( ?) would get very sloppy. did some adjusting which make thing not so great.


I have an old 15 clone, so I took all those parts from that machine and they now live in this one. There a direct fit, The difference was, a better quality steel, larger wear surfaces and a longer pivot post for that bearing.

the japanese clone was all heat treated fasteners , the Ph machine is all mild steel fasteners

The donor is a occupied japan machine ( 1947 to 54) this one is made in Philippines (?) and made after 1959

I just wanted to say that I love that faceplate! And while I've seen a a machine before with the sew master emblem on it, never really paid much attention to it.but this machine looks pretty clean and all.

Sewmaster named machines have been built all over the globe. I have one that is a carbon copy of the Singer 834 and it was made in Poland. My local SMG told me it was made in the old Singer plant there. Most Singer parts will interchange in it. I have seen other machines made there that have different names on them.

Very much different from a 15 or a 66 on that end. The arm casting is a different shape along with the faceplate. The bottom half looks to be straight up 15 or 15 clone though. Still, I wouldn't rule out the idea that at least part of yours came out of the same molds as the authorized Singers. Mrs.SewnSew's machine is just as confusing. It appears to be an authorized Singer machine but shares many of the same features as yours.

you right that take up arm and links are not from a 66

I thought the tensioner was from a 201, but it's from a 237 style I didn't check the take up arm as a match to the 237 . The only difference between a 201 / 237 tension system was the location of the mount screw for the take up spring stop.
I have the machine working well again , I knew it must have worked good, it has seen a lot of use, it wasn't a closet queen
when I test sew, again this is a treadle. I use old bed sheets, so that 7 feet long, yes the in strips. using these 10 or 12 inch piece doesn't really tell you much. doing this I've used over 300 yds of thread it sews as good as any.

so two nights ago what the hay, I get out the hoop and a hopping foot ? the spring thingy that attaches to then needle bar. another full spool of thread 300 yds, ( 30 yr old thread)

This is about the 2nd time I've tried this and first ever using the spring deal..

I have to say it's kinda fun, I stopped and rewaxed the table top,(in hopes the hoop would slide around smoother ) and now am doing this using a 15 clone ( treadle)
butt what the hay..

I'm still working on it's cabinet, building inner shelves that were mostly gone, and rebuilding it's lid, which is now soaking in water, thats to get the thing apart to reglue, the entire lid

Rodney

Nice. Better than a lot of my attempts at free hand embroidery or darning. Maybe I should start using a hoop too when I can.
