Really good demo! And a very nice set up. That balancer is a bonus. For tire install, I butter up the rim & tire just as you did, but then flip the tire over and walk the first bead on by hand (push on left, right, left etc). ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-H_c2ZMIYWdE.html Just did tires on the lads CX5 19" alloy wheels the same way.
Thanks for the nice comment! I enjoyed watching your video! I like your homemade duckbill tool - great idea and looks like it works really well! I like your balancing technique too - pretty cool! Nice to hear from a fellow DIY tire changer!
I used clamping collars to hold the pipe on the side of the duckbill arm. Then the other pipe used as a handle slides into that pipe. To fasten the clamping collars to the duckbill tool, I just drilled a hole in the collars and tapped it to accept a bolt which goes through the duckbill tool arm. Let me know if that isn't clear! Here is a link to the clamping collars: smile.amazon.com/gp/product/B0063L0E9W/
