Gill, ALf,
Thanks for the links and advice-much appreciated!
Typically, I found a great article in a Fine Woodworking book at home, the bench tools one.
Had a play with it on the weekend, it's somewhat different to the planes I am used to. You pull the plane toward you, as with Japanese saws, and this is a little strange. Got the hang of it quite quickly though. You set the iron by hitting the body with a hammer-at the back to decrease the cut and the front to increase. Interesting! (you won't see me hitting my Cliftons and L-N's with a hammer!) Didn't take long to suss it out though. The plane body needs a little work to fit the iron-only dissapointment I found was that the mouth of the plane was cut quite generously. I wanted to use this for final smoothing, not a lot of chance with a wide mouth. Took some pretty fine shavings though (although not with Purpleheart and its twisty grain!!). I'm thinking of making a Krenov style wooden plane, and the iron from this Japanese one would be perfect-it is Huge!
I'll post some photo's shortly.
Thanks again,
Philly
