Paper tuning frame

Beschreibung

This model creates a paper tuning frame for arrow/bow tuning. Two axles allow paper to be wound from one axle to the other whilst allowing tension to be maintained on the paper. A ratchet-type mechanism prevents the paper unrolling. Designed to hold a 12" wide paper. Overall paper width between rollers approximately 250mm The design requires a length of 20mm round conduit pipe to form the axles. I've designed the spigot to fit inside a 22mm pipe and a mount to fit the frame in a mobile phone holder. 20mm clips attach the paper roll to the tube axles.
