Part 1: Sharpening Blades / Irons

01-13-2014 11:27 PM by OSU55 | 10 comments »

I have been fortunate enough to assemble and use an array of handplanes – Stanley Bailey bench, block, and specific use planes, oriental woodies of various sizes, Lee Valley Veritas bevel up and scraper planes, and some other assorted types. It took a while, as in 4-5 years of using, fettling, trying various methods of things and different plane designs to form up some conclusions from my experiences. I thought I would pass along these experiences, primarily with the lesser experienced in min...

Part 2: Sole Flatness

01-15-2014 05:04 PM by OSU55 | 7 comments »

Why Sole Flatness?Convex (bulging out) and concave (hollowed out) soles will cause uneven cut depths and skipping and chattering. For a convex shape, the plane rocks front to back and/or side to side. A concave shape will cause heavier cuts at the start and end of a surface, and possibly no cut in the middle. Different amounts of downward hand pressure can affect each stroke causing more confusion. Even with a very flat sole varying downward pressure will affect the cut. Reduce the variables ...

Part 3: Chip Breakers & Cap Irons

01-21-2014 05:50 PM by OSU55 | 7 comments »

Cap iron or chip breaker, blade or iron – Some folks write treatises about which term is “correct”. I use the one that comes to mind, they mean the same thing. Chip Breaker Function The chip breaker adds mass to the blade and adds stiffness to the blade, and with the lever cap pushing down, seats breaker & blade flat on the frog, creating more blade stiffness (cap iron). A very important, but lesser known, function of the chip breaker is to create a force down the wood fibers as the...

Part 4: Frog / Lever Cap

02-03-2014 03:46 PM by OSU55 | 2 comments »

The lever cap, chip breaker, blade, frog, and main casting all need to be held together well to act more or less as a single mass. Major sources of chatter are the frog not seated to the bed well, and the blade not seated on the frog well:.. • The blade needs to seat flat against the lower 1/3rd of the frog. • The frog needs to seat well into the main bed. • The chip breaker needs to seat well to the blade. • The lever cap needs to seat well to the top of the chip breaker..Frog.It is not ...

Part 5: Schwarz On Honing - Guides vs Freehand

05-12-2014 11:37 AM by OSU55 | 8 comments »

The Church of ‘Leave me Alone, Please’ By: Christopher Schwarz | May 1, 2014 During the last 17 years that I have been using a honing guide to sharpen, I’ve been approached (sometimes nearly assaulted) by people who want to teach me to sharpen freehand. My response: “I sharpen freehand all the time.” They don’t believe me, and so they spend an hour or so to show me how they hone their edges. Then they want me to try their technique and say: “That’s fantastic! I’m throwing away my ...
