Router Plane Upgrades

The photos above show the first of two simple modifications I've made to a couple of router planes I own. It allows more accurate control of the height of the cutter in a Record #722, in much the same way that you can adjust the cutter height on a Veritas large router plane or a Stanley #71. It's not an original idea: it was based on something I saw on a woodworking forum and decided to copy. Unfortunately, I can't find the original post now, so I can't credit the originator.

The Record #722 had two 6 mm holes for the cutter, spaced 20 mm apart. The clamping screw is shared between the two holes:

I drilled a hole in between the two cutter holes and tapped it M5, not letting the tap go all the way through so that I could tighten a bit of threaded rod into the hole:

M5 has a 0.8 mm pitch, which is fairly close to the pitch of the (inch-sized) screw that is fitted to the Veritas router plane.

This photo shows the two pieces that form the height adjuster.

While I was at it, I also made this:

It's a depth stop for the Stanley #71 based on the excellent one for the Veritas router plane:

I am a hobbyist metalworker and woodworker. I work as an electronic design engineer and spend most of my working days in front of a computer so I enjoy having the opportunity to use my hands and make things in my spare time. I particularly enjoy making tools as I can then use them on other projects. This website showcases some of the things I've made.
