A jig for planing super thin parts


Article Image

Small planer. The rails of this jig are
spaced to be simply wider than the blade of a No. four smoother.
They’re only a hair thicker than three/16 in., in order that boards
planed with the jig find yourself three/16 in. thick. A cleat is clamped
in a vise to carry the jig nonetheless throughout use.

I make small packing containers with sides which are three/16 in. thick.
Making ready inventory this skinny is an issue, as a result of my planer
begins to chew up boards when I attempt to go below 1/four in. thick.
At finest, I get boards that don’t have any tearout however aren’t a
constant thickness. I’m lucky that there’s a drum sander
within the store right here at Superb Woodworking, nevertheless it’s not all the time
convenienent to make use of (I reside about 35 minutes from work). So,
earlier than I made some current packing containers, I sat down to consider how
I might mill small items of inventory to three/16 in. thick. That’s
once I remembered an article by John Reed Fox in FWW #226 that
explains how he makes kumiko, a sort of Japanese lattice that
requires exactly milled skinny items of inventory. He tacks a
strip of wooden to the only of his Japanese aircraft on both facet
of the blade. These strips are depth stops and permit him to
repeatedly aircraft inventory to the identical, constant thickness. I
have steel planes, so couldn’t tack something to them. As a substitute,
I made a planing cease and tacked the skinny strips to it. They’re
spaced to be simply wider than the blade of my No. four smoother.
There’s a information on every of the strips that hold the aircraft
transferring in a straight line. The entire rig clamps into my bench
vise and works nice. I get superbly planed inventory that’s
lifeless on three/16 in. thick. Check out the photographs above to see
the way it works.
