here starts a series about sharpening.
First, I'll show my jig for jointer blade sharpening for my wet grinder.
This is a serious one, it works like a charm and was really worth doing it, because the Tormek equivalent is quite expensive.
This design, I'm proud to say, is from me.
As I already said, the Tormek style grinder (this yelow one is a Schepach one, but the idea is from Tormek) uses a round bar as a tool rest that goes transversely in front off the wheel. You can easily setup the distance between the bar and the wheel.
The round bar is rarely used as is, it is mainly intended to be used with all sorts of jigs, depending on what you want to sharpen.
So I made this jig out of red wood (mahogany like) and aluminium. There is a bed that is gripped on the tool rest bar. As it can turn around the bar, I added a little leg to act as an angle stop (this piece of turned beech, with threaded rod and a wing nut).
Here is a rear view to show how the bed is clamped to the bar.
Inlaid in the bed, acting as a slide, there is this long aluminium rod, of square section.
And sliding along this guide, there is the mobile part that supports the blade to be sharpened.
The blade is inserted in the slot and hold in position thanks to four big screws with hex head, that can be tightened by hand. (can be better seen on the first picture above)
Here is the jig, upside down
And last but not least, I have a video showing how it is used :
Sorry for the bad quality of the image...
Note the two little red clamps I put at each end of the rod as stops to avoid the blade dropping down from the wheel.
(Did you notice how it's always when you're filming something serious that the pen cap takes the opportunity to drop on the floor ...)
