00:08 A few thoughts before making pen holder.
00:50 Cutting and de-burring pipe.
01:06 Assembling the components, and padding out pen to fit within inner diameter of pipe.
03:33 Error with original components.
3:49 I used a pipe which I drilled to the same diameter at the pen to clear the spindle and weight the nib when drawing.
4:36 Test drawing.
