Belt Sander Grinding Table

I have been wanting to move my hand tool grinding to a belt sander.  My hand grinder works, but is really tough to get an accurate angle.  Also despite the slow speed I have still managed to burn blades on it.  Belt sanders remove material more slowly, but don’t get nearly as hot.  The build is hard to explain, so I will start with the finished product.

It is essentially a small flat surface that sits on the same plane as the moving sanding belt.  Because the table isn’t moving you can use your favorite honing guide jig to keep a really accurate angle.

The table is held in place with an “L” shaped piece of wood.  I cut the groove on the table saw wide enough to catch the top of the sander surface, but not so wide it interferes with the moving belt.

I attached a piece of plywood to the inside of that L so that the top of the plywood would be co-planar with the top of the sander.

I took the table surface to the belt sander to cut that angled shape.  It needs to conform as closely as possible to the flat top of the sander so you don’t end up grinding on the rounded section of the belt sander.  I had issues with the pine sliding on the painted sander sides so I threw a few pieces of PSA backed sand paper on it to prevent the jig from sliding around.  Finally a clamp keeps it all in place and very stable.

I reground a plane blade and a few chisels that needed resetting or bevel changes.  The little table worked like a charm.  I can go from the belt grinder to my honing stones without even taking the tool out of the honing guide!
