We're making a new winch drum. The flanges on our drum bent out a little when moving from steel to Spectra line.

I'd like to know the dimensions and structure of any drums/flanges that have failed, or shown signs of failing, and with what length and type of line. Please pass this on to anyone who has details on that.
