In order to polish my skill, I bought a bunch of Fancy Slimline kits from CSUSA. I'm only few month new to the pen turning. I've successfully turned several blanks. However when I try to assemble cap and clip, the cap stuck at the clip hole and wouldn't go though easily. Do you think it might be defected parts or It is normal for cheap kits like slimline? If anyone had similar problem, how do you solve it?
