Hello everyone, I tried building my first two comfort pens today with bad results. The bushing that were supplied with the kits were from PSI and were not the correct size. Has anyone had this happen to them? The instructions said there are 3 bushing put the samll one on the writting end and the other two which are larger in the middle and top of the pen. The one of the top is way too large for the hardware that comes with the pen kit. Did I do things correct or wrong. Thanks in advance - Malcolm
