Perfectly round cowl opening
It you carve your own engine cowl for a radial engine, and want the front intake perfectly
round, find a wine or pop bottle and glue sandpaper around the tapered part of the bottle
in the shape of a cone. Insert this into the opening and turn gently around and around until
you get the size correct.
They wont take the bottle at the recycle depot, so you might as well save it for your next project!
