Capital Window-Matic (Brother 1950s)

The team at Brother way back then must have been quite something. Like any product manufacturing company on the rise they had a mission and by the 60s had become a premier maker of machines.

Finally we get some styling and the beginnings of some more considered HMI added to the machine. HMI is Human Machine Interface and in this case the super vague 15-91 style froward - reverse lever in replaced with the classic Brother window gauge.

Another outstanding 15-91 machine could sum it up because that is all it is. Manufacturing guys really like making what they made yesterday and so the incremental changes we see in the Japanese imports are minuscule and usually very well executed.

Another "all metal parts off" restore that went pretty smooth but the stamped, masked, and painted logo did not go into the SuperClean, the paint that is used in these masking operations is vary thin and comes off with a single dip into a high level cleaner. I use Pine-Sol and a tooth brush.

A close up of the window system, not easy at all to reassemble, don't do it if you are not competent in repairs. The dial does what you think; it moves the needle and changes the stitch length BUT it only pushes the 15-9 style lever up and cannot push it down (you'll see when you try it) again, its a very early attempt at improving the system.

I'll say here that "all metal parts off" restore is NOT for the newbie, you will end up with a pile of parts that a machine you can't use. If you have no experience with machine repair then I suggest you start out very slow and do not willy-nilly disassemble anything.

The reason that I do "all metal parts off" is because I really get annoyed at the little edge of oil grime between the metal parts and the painted casting; this is so difficult to get at that the only way is to remove parts, though you don't have to. Removal also makes the cleanup of those parts easy, the trade-off is the reassembly know-how and lots of time.
