Spinman1949,I can do a how to. What I am thinking is a how to based on common hardware everyone can find.
When I designed my Axworthy I actually had never seen one. This dates back about 7 years. I never thought about using bike wheels. So from the very beginning I knew I had to use high tension to keep the line on the sliding glass door rollers I wanted to use. The sliding glass door rollers can handle a very heavy load and are well suited for this application. I use a bungee cord to pull the line very tight. It is attached to a swing arm that one roller is attached to. 40 lb line is not strong enough to deal with the tension placed on this line. I currently use 200 lb dacron line. It resists stretching as well.Spinman1949,
That would be great if you could do a How-To. I had an Axworthy Ghost running this year. In fact, it received the most compliments.
I used a Dayton motor, bike wheels, and 40 lb. fishing line. Some how, it work all night on Halloween but broke several times when I first tested it. My rig was also very noisy. I'm looking for ways to improve for next year. Any advice would be appreciated.
I will be working on the how to re the small pulley axworthy in the next few weeks. I have quite a bit on my plate. I am also working on a new and improved 3 axis design, and I am playing with my 2 axis eye design to remove all geometric error.Now I gotta find some more details on this prop... I really look forward to your To Do.
I'm guessing it's possible to have multiple points/pulleys as long as tension can be maintained.
I also saw your 3 axis head prop (and 2 eyes)... Just floored, that is probably the best implementation I have seen. I'm not a big fan of talking heads, since they just don't seems especially fluid but this made me reconsider.
