Greetings from Nebraska. I am planning on making new HDPE sleeves to cover the aluminum and UHMW contact surfaces on my PSI pen press. I think the HDPE should reduce the risk of marring the parts because it is softer than the aluminum and UHMW parts.
The UHMW (spring loaded) end of my press has a tapered hole in it. I assume that this was done to accomoadate the tip when pressing; however, some of the pens I have pressed have an obvious ring on the tip that can be seen in reflection after being pressed. I assume this is because a point contact in the tapered hole on the UHMW is deforming the tip or plating on the tip.
So, as of now I am planning on making the sleeve flat on the face, forgoing any kind of hole for the tip unless I am missing something. Does the tapered hole provide some kind of advantage that I am not aware of? It looks like most pen presses and pen pressing devices have this tapered hole on one of their faces.
Regards,
Dave
