Project for changing Bondtech QR to VQR


Recommended Posts

Posted (edited) · Project for changing Bondtech QR to VQR

I love my Bondtech QR3.0.   But myself and some others who've become accustomed to the quick and easy release mechanism in Robert's feeder are not completely satisfied with the stock QR3.0 spring-loaded screw adjustment mechanism.  The screw works, but it could be better.   So I started working with ideas on how to make a faster release that provided enough pressure.  

v1.1 has been in use for a few days on both of my UM2s.  So far they've been working well, but some improvements are needed, such as easy tension adjustments and maybe a guide for the cords where they pass around the bowden tube.   Some manipulation is required each time when latching with this version to make sure the cords stay off to the sides, not touching the tube.
