The tedious part of making your own ladder line is to keep the
spacing uniform. Spacing is very critical for closely spaced wires
like for 450 ohm or so; whereas, wider spacing like 6 inches
for 600 ohm using #12 wire is quite a bit more forgiving. Some
good information about open wire is at:

For spacers, consider using lexan strips 1 inch wide by 6.5
inches long. Place the wire on center at one end and heat
it with a soldering gun until the wire melts 1/4 inch into the
lexan. Messy but maybe quicker than drilling 1000 holes.
