bunkeru2k -- THANK you, for the terrific compliments, and very kind words! I am always happy to work with any customer who needs a custom shaft, to try and meet whatever needs they might have.
Zofchak -- yes, I could build you a shaft which would allow the coil would twist in line with the screen. I have an idea as to what you are looking for, and how I might be able to meet your needs; let me know if I can be of service.
Thanks!
Steve
