[modeleng] Re: Pins-striping tool

I saw this also, the moment they appeared on the market, and I wondered how 
they could be successful.  I too spent many years pushing technical drafting 
pens (such as Rapidograph, K&E LeRoi, Staedtler) around sheets of vellum and 
although they were a godsend when compared to bow pens (which I am also old 
enough to have used) they were not without their problems, principally caused 
by contaminated or dried ink.  Relative humidity and barometric pressure could 
adversely affect their operation and in any case at least a couple of hours a 
week needed to be spent in maintenance to produce consistent and trouble-free 
performance.

Drafting ink and paint are dramatically different animals so far as density and 
viscosity and it's always been my thought that "paint" simply wouldn't work in 
a technical pen unless the paint was thinned to the point of being ineffective, 
or some substantial alteration had been made to the pen to allow it to function 
with the much heavier liquid.  Since apparently the Moore pens do work (or they 
continue to sell without public complaint) I have to assume they have been 
altered in some way from their ink pen cousins.  Whether or not any of the 
above mfgs still produce drafting pens I don't know.  I still have a box-full 
of pens and replacement nibs . . . maybe someday I'll give them a try with 
lining paints, but franbkly I am more likely to go back to the bow pen for this 
as I know that will work.

Harry Wade
