zorki 4 take-up spool

[Mauro]

Does the Zorki 4 need a take up spool with 2 pegs?
I got a Zorki 4 with its spool (without pegs), and it seems that the spool slips when winding the film.
What should I do? any help and tip will be greatly appreciated.

The replacement spools are often 'loose'. A spool loose on its spindle in a Zorki-4 (and its contemporaries like the Zorki-5, Zenit, etc) does not automatically mean its non-functional. Have you tried using the spool which came with your Zorki-4? Its not the tightness or fit of the spool on the spindle which usually determines the efficiency of the spool, but rather how the sprocket teeth is able to space frames properly. The spool in my Zork-4 is very loose but film advance and frame spacing is perfect. What is important to observe is that the spool should be able to reel film in as it's being moved by the sprocket teeth.

Dear Jay,
thanks for your reply. I tried to use the spool I got with the Zorki, but I damaged the film: the sprocket teeth advanced the film, but the spool was slipping so the film was not rolled up on it.
I discovered that the spool has two holes: I put a small piece of a wooden stick in it, it engages the wind fork and now the spool roll up the film
