Hi Glen, The Delrin rod I used was relitively tight in the feed lips and would not allow for a label to be attached. The 3/8" aluminum rod had adaquate room and is relatively easy to machine. But, the real fly in the Delrin ointment was expense, it cost a lot for a piece of plastic!
Still it is amazing stuff, and I use it when ever the needs arise.Best to you, til.....lat'r....GT...
