My sister wants a top with an ink pen on the bottom to trace out it's route. I figure I can make a top and drill for an ink pen, but I need a short insert--about 1". Where can I find an insert like that? If I can't get one that size, is there one I can safely cut?

I think the problem there is going to be ink flow. I used to work for a company that made plotters, and our big problem was getting ink to flow - the faster we made the plotters the bigger the problem got. You might have better luck with an drafting pen point like the ones here:
Even there, when we got to really high speeds we had to remove the little wire from the barrel and depend on capillary action alone - had to experiment with inks to find one that would flow but not drip.
You'd want to remove the wire anyway as it wouldn't spin very well without digging in.
It's not as simple as it looks. But maybe you'll get lucky and prove me wrong - it's been almost 50 years that I was involved in this. But I see the drafting points haven't changed much.
Just for kicks, here's an ad for the high speed plotter we had - the head was on an air cushion with a linear magnetic motor.

I tried threading the pencil. The cedar was so soft all it did was shred the pencil. Just a FYI: pencils don't thread very nicely.
