Auragami Update #2

May 17, 2013

Hi Everyone

Today the top was flattened and I found a nice slab of 16″ wide 10/4 Ash I will use for the base.







If you would like to see more frequent updates and photos, follow the link and like my Facebook page. I tend to post there a few times a week:

Last night during a weekly woodworking get together called Woodchat we discussed hand planes. We talked a bit about Japanese planes in the discussion but I didn’t have a chance to explain their construction in much detail so I decided to make this quick post to clear up a misconception.

Many woodworkers who see a Japanese plane think the blade is secured in place by a wedge and pin. This is not the case. What appears to be a wedge is actually the chip breaker or as I call it sub-blade. The steel pin holds the sub blade against the main blade. The main blade is held in place via a wedge fit to the body ( dai ). Not only is the main blade a wedge shape, it is also slightly curved along its width and length. The combination of this blade & dai geometry securely holds the main blade in place, no pins or wedges needed. Many Japanese planes are in fact a single blade set into the dai. I don’t have time to go into much more detail today so hopefully these photos will help clear up this misconception.

Take Care
