Conversion of White 77 to Treadle
I have commented on the list a number of times about how much I like and respect
the White Family Rotary machine design. This design continued in production
in one form or another from about 1895 through the late 1950’s, when white
moved their operation to Japan and began importing typical Japanese clones of
the Singer 15.
The final version of the White FR was the Model 77, a real tank of a sewing
machine, and the only one I have encountered that had separate stitch length
controls for forward and reverse. It is a marvelous machine, and not only the
last development of the FR, but also, I believe the last of the friction drive
machines. As much as I love the FR mechanism, I have never been a fan of the
friction drive, which is quite smooth, but lacks the power of belt drive.
I have had several 77’s and always lamented that they were not readily
convertible to treadle operation. Well, Rick and Susie down south do some very
imaginative things (see their hand crank Featherweight!). Rick sent me this
material on converting a 77 to treadle:
Hi Captain,
Bet you can't guess what I've been up to this after noon. After you made a post
on the 77 I remembered we have one of those. Went to the SM recycle center and
retrieved it.
Here's what I did. Took the wheel cap off, & drilled it in center for a
3/8" NC bolt.(slightly larger hole). The bolt is a round head with the
square base, I call them carriage bolts. Put the bolt in the hole & gently
tapped it through the hole until the square base seated itself nicely in the
cap. then I took a pulley from an old WW & reversed it so I could get the
clearance for the belt. Then I put a 3/8" self locking nut on it. It looks
odd but it works well.
Neat reverse on this machine. Hope this helps.
Rick & Suzie

Rick did a nice job, and shows how to put a really great old machine back into service as a people powered unit. I have had several but let them get away. Now I will be on the lookout for another so I can do this too!
