Re: Quick Lips
Hi Longball
Just went out to the shed and took a couple of close up's of the slot etc which includes the lower half of the punch "barrell".
As I hope you can see the punch passes past the slot which is where the cut is made. When the punch is raised and the sheet is placed fully into the slot. The punch is then driven down against the sheet, which in turn is forced against the lower edge of the slot (same diameter as punch here), this force causes the sheet to sheer off (in this case a circle). You would be suprised how easy it cuts sheet Brass, Aluminum, Lexan which are all about 5mm thick (not sure in " s). As I am sure you know, this is nothing new, it's just a die punch but instead of complicated shapes for lips I have made it round as it is easy to source and no huge cost in having a die made, I have been down that road with a die I had made for hook hangers. I think she divorced me around then!!
As I think I said in the previous post, if you shape the end of the punch the lips (not Lexan) will be bent to this shape also, it's up to your imagionation I suppose.
Hope this helps, if not, keep asking. See 2 x pics Pete
