no, auger ribbon. I have access to flighting. I want to build a snowblower auger.
I will been doing more research, have not found an app. But I can describe what I am looking for with better terminology. Say I want to make a Helix out of 1 1/2 x 1/4 inch flat bar, that is 12" in diameter and has a pitch of 12" also. What is the diameter of the circle I want to roll the flat bar to, before I stretch it out to a 12" pitch? In theory if I find the length of the od of the finished Helix, that would give me the circumference of the circle I want to roll the flat bar to. But I think I might still be missing something.
These numbers need explaining. Also looks like you forgot the 12" pitch?Lookup surface-flattening algorithm or surface-flattening software.
I came up with 10.4149" diameter for the roll to be stretched out and 35.14" length for each complete wrap (assuming the neutral axis is in the center of the bar when rolled the hard way. Make it longer).
These numbers need explaining. Also looks like you forgot the 12" pitch?
ID of the part should be more like 12.8" and if you add 1 1/2" to get to center of axis it is 14.3" Or OP wants to measure OD then 15.8" or so
