About the Glide Foot accessory for my Sweet 16 (posted last week here). The newer machine models (not sure of exactly when the change came!) come with the newer shaft in place, making the use of the quick-change specialty feet possible. Here is a photo of my machine with this set-up……..And, yes, I had to make the conversion kit purchase.
Note that the foot slides on the shaft and is held in place by a hex-head screw that goes completely through the foot/shaft/foot. If your SS has the old shaft (which would have the ruler or open toe foot as part of the shaft!!!) you must purchase a conversion kit. This kit contains the tools needed for the conversion, the new threaded shaft, a ruler and open-toe feet.
I hope this clarifies what is needed in order to use the Glide Foot a wee bit. Let me know if there are further questions and I’ll do my best to give you direction.
