Kilting and Minishing

"Up and down to adjust the firmly screw, you will find the different deepness of kilted." Is it poetry or philosophy? It's a ruffler.

A marks the firmly screw

Unfirmly the screw and adjust the arm up and down to deeply or undeeply kilt. On the left, there is a section of arm up kilting and on the right, arm down kilting.

In case the picture isn't clear, here's a drawing of what's what.

Arm up, Arm down

"Acording to this direction to adust, You will increase the pull of the blade, Contrarily the pull will be minished." It's been a long time since I was in iaido, but dig it.

B the minish

This must be to adjust the strength with which the blade falls, for lighter or heavier fabrics I suppose.

And some industrial strength kilting action...
