1-3 For routing long vertical rails it may be necessary to build
a jig stand to mount securely on your bench. Make the stand and
bench height combination sufficient to accept the board length
you have in mind. The jig stand should be bolted securely to the bench.
Make up a stable platform as shown here to stand on. Do not use
a collapsible step stool, these are unstable and unsafe.
