So, after producing 15 or so poles on my x winder I was wondering what everyone has been using for their mandrels? So far it looks like cardboard is popular, but I imagine this would be too inconsistent for my parts. I have read that mandrels should have a slight taper, to help with removal, so was thinking about 3d printing some mandrels and then giving them a wrap on the filament winder (to add sufficient strength) and I would then use these as the future removable mandrels for my projects. Has anyone found better sources of mandrels?
I am very keen to develop some better mandrels as the tube stock I have been purchasing has been very difficult to remove from the finished part unless I use many layers of cash register tape (which causes it’s own problems). Has anyone developed a good way of releasing their finished parts?
