Winder Types
    A simple motorized winder might employ a motor driving the bobbin directly. More complex machines might incorporate gearing, variable speed, tailstock clamping, a 'limiter' assembly, tensioning devices, auto traversing, auto shut-off, etc.
The would-be builder/designer is confronted with two main types of pickup winder -     The 'Open-faced Winder' setup is where the bobbin is screwed to a faceplate or mounting (secure double-sided adhesive tape can provide an alternative to screw-fixing). The outermost face of the pickup bobbin is otherwise unsupported, save for the addition of an optional reinforcing plate (or 'spacer' plate), acting like a 'washer' to spread the screw pressure.


An 'Open-faced' Winder made from an extensively modified
medical flask shaker.
note: the speed control knob, on/off switch on the front panel,
and my 'trademark' limiters and handrest.

     The 'Tailstock Winder' has a tailstock incorporating a 'live centre'* which is adjusted up to the outermost face of the pickup for added support and centring*. Spacer plates can be added to further brace the bobbin.

    The above unit was made from 'trashed' castings, a newly-made bed, and rebushed bearings. The castings, in their original 'ex factory application', were set vertically, somewhat like a small drill press. My new bed re-positioned them, and a large wooden knob (at left) was turned to fit the existing flange. The tailstock is rack activated either by the large wooden knob, or a knurled aluminium knob frontside. Locking is via black screw on top. The 'live centre' was home engineered with integral bearing, and a 125mm.(5") wooden pulley is driven by an 'O' ring (as is the counter).
Counter and adjustable motor box located lower right. Handrest and limiters - at top. Limiters are 'pillar' (not bed) mounted.
My experience with 'tailstock' winders suggests that they offer the possibility for smoother and more consistent winding.

* U.S. readers please read 'centre' as 'center', and later 'centring' to read 'centering' - due to differing spelling conventions.
