Working with inter-century technologies

I threaded this 1897 machine with blue thread and the new electric machine with black so I could work between the two devices. Though my foot kept tapping about for the pedal on the old one.

Winding thread on the bobbin is an exercise in engineering.

I focused so much on winding the bobbin I forgot how to put it back in the machine.

Lucky I had the 105 year old instruction manual handy.

Easy.

While I was at it, I changed needles.
