Do you have the black 66 or the grey 100 model.
Assuming the grey one, insert roll and put the leader thru the hole and over the winding counter. Replace the cover and rotate it so the film slit closes.
Pull out three inches of film and attach to the spool using tape all the way around the spool and attaching to the film on both sides. Put the spool in the can and add the end cap and place in winding area. Close cover and set counter to 37. Open film slit by rotating the film cover to open. Door must be shut and lever down to make this happen. Wind on as many exposures as you desire plus 3.
The 3 become the leader. Close slit and open cover. Cut off film near film sprocket counter. Force 3 more inched thru closed trap and attach it to next spool. Repeat above.
Watch the film counter on the camera so you do not exceed the number of frames you put on the roll, otherwise the last two or three will be on the exposed tail with the tape.
The black 66 model has issues and is what I started with. Made a lot nicer, but doesn`t work as well as the doop will pop open when winding up the film. I modified the inside of the flat cover after 40 years to look like in inside of the cheaply made grey one. Now I have the best of both and there is a roll of film in each right now.
