Looking for grinding jig ideas?

[BryanR]

I've got multiple old files and car springs that I need to surface grind flat the length of the knife. I remember someone using a piece of wood as a press with magnets to help hold the blank to the wood. Is this the standard way it's done, or are there any other ways.

P.S. Cheap ways, not mill machine cost.

The most direct way would be to flatten your work against the platen. I use a magnet to hold the work when doing anything like this, saves skin.

Now there's a DUH moment. Why didn't I think of that? I've got several good, strong magnets.

Thanks for the tip Dave.

I made a magnet block, just for that purpose. I took a piece of scrap wood, and drilled two holes in it, just big enough for a couple of those rare earth cobalt magnets(not the little bitty ones, the ones about the size of a penny) and epoxied the magnets in just below being flush with the surface. Works very well, but if I had to do it again, I think I'd use a piece of micarta instead of the scrap wood.

u can use the magnets of an old hdd. if you are going to buy the magnets, make sure to get the thinnest you can get. the thicker ones might pull your blade towards the platen

I didn't have any magnets so what I did(this is for a blan that is drilled out already) was run dowels through a piece of wood matcking the holes on the handle made for a good one time user or any other time I do that blank. A quicky solution.
