Hi all---
I am making nose ribs in my hydraulic press with a thick rubber pad.
They are coming out very nice except the my lightening hole flanges are
not quite turning over (bending) quite enough. I THINK my rubber isnt
quite extruding down into the hole far enough to full bend the flange to
30 degrees. I am thinking I need a slightly softer rubber. I think my current
rubber is some kind of carbon type rubber----- but I have read that a
polyurethane version is the best performing kind for this application.
Can some one advise me what durometer and thickness that is good ?
(Im actualy building a bearhawk--- not an RV---- but dont tell anyone ! )
Bob admits that he "stole" the RV's wing construction style because he
he must have thought it was so sensible....
Thanks ahead of time for any guideance.
