|First and only test groove made two years ago|
There is nothing square about this plane. Maybe things were square when it was built, but now - not so much. I though a lot about what surfaces should be square and flat and decided on a few. First was the fence. The face of the fence that rides on the workpiece should be flat. And it should be square to the top surface of the fence where the screw arm posts are attached.
|These two surfaces should be flat and square to each other|
|Boxwood wear surface was let into the fence|
|That's a lot of daylight under the square|
|Holy crap, Batman!|
|Arrow is at most fragile point|
|Checking alignment by looking from end|
|And checking with a straight edge|
One more area where flatness and squareness are important is the bottom of the screw arm post. This surface mates with the upper (and now flat) surface of the fence. Not only should this surface be flat, but it should also be parallel to the screw.

|About 1 1/8" here ...|

|Shocking!! As good as I could have hoped for!|
Aside from all these out-of-square issues, there was a small problem (that could be a large problem later) with the depth adjustment. The mechanism works fine, but the mortise that houses the brass plate that is screwed to the plane body is damaged.
|Plate not seated properly in mortise|
|Rear aspect of the area - note the crack at bottom right|
|Front aspect - smaller crack bottom left|
|Locking thumb screw pinches the brass portion below the plate so the adjuster can't be turned|
|It pushes the whole mechanism against the thin wall at left side|
|Adjuster in proper position|
|Can see the hole in the plane body is off-center from the brass hole|
|Cutting some plugs in beech - needed two for each hole to get enough length|
|Shaved them a bit since they are tapered from the plug cutter and I don't want to wedge the plane body apart|
|Two plugs glued into each hole|
When the glue had set, I drilled new holes for the screws, trying to be as accurate as possible. I also tried to get some superglue into the cracks along the thin wall and clamped it in the vise to pull that wall back in.
|Holes drilled and superglue applied in cracks|
|Shavings glued into to open area on left.|
|Looking much better|
|Blurry pic from the other angle|
|Looks pretty good, but lets measure|
|Just shy of 12/32" at top|
|Just shy of 12/32" at bottom - BANG ON!!|
|Before filing - lots of light coming through at front and back|
The next post will be about the irons and wedge.
