Kanna maintenance
16 August 2011 Filed in: Tools
It’s a bit quiet at the moment, so an ideal chance to do some serious maintenance on my kanna. All the dai need a bit of work, and a couple of the 70 mm blades need to be tapped out.
This is what happens to the tsutsumi as the sole of the kanna is conditioned numerous times.
The tsutsumi is a small extension from the bed, and serves no real purpose. It does, though, indicate quality in that the dai has been made by hand and not by machine. Over time, these remains of the tsutsumi will gradually disappear with each round of sole conditioning.
This is one of the blades that needs tapping out. This is the blade I tapped out in my blog entry here at the end of April, and this will be the second time I’ve tapped it out since then. My other 70 mm plane blades have also been tapped out a few times since then as well. I sharpen my blades often, so tapping out is a regular occurrence.
I had to work on this blade a bit, so you’ll notice that the flat is very thin, and in one place, virtually gone altogether. When the flat disappears, this is called uragire.

New screen for products page - asa-no-ha band
08 August 2011 Filed in: Work Projects
I’m in the process of making up a new standard screen for the products page. This one contains an asa-no-ha band. This is quite fiddly, as many of the vertical kumiko require different cuts, so it’s a matter of constant removal and replacement of the kumiko from the jig as I make the cuts. Also, the second (and fourth) panel is a mirror image of the first and third, so care is essential here that the kumiko are assembled in the correct order.
These are the kumiko in their appropriate panel groups.
So far, so good. The shortened horizontal kumiko are chamfered on the ends on three sides.
Safely completed with no dramas.
Tomorrow, I start on the frames.
The timber is Victorian Ash.
