Topic tags/keywords: workbench finishing round-over

I am almost done with my Holtzappfel bench (hooray!). So am thinking about finishing touches. As I milled all the wood carefully, all the edges (except parts of the legs which I already chamfered)are “knife-edge”. The question is what to do with them. I built the bench out of Southern Yellow Pine which is relatively soft. A couple of spots already got dings in them (as I am already using the bench ;-).

So what to do? Options:

  1. leave it
  2. “break” the edges by sanding
  3. roll the edges over with a round-over router bit

I am inclined to #3, round-over. I have 1/8” roundover bit which would be a breeze. Seems like a reasonable way to minimize the inevitable dings. I don’t see a real downside – I think it is mainly an aesthetic question, but thought I would throw it out there.

BTW, there is a variant of this for the chops of the two vices, which are also currently knife-edges, but they are hard maple.

I would use either a round over or a chamfer. I chose a chamfer for my bench works well fro me

I personally like chamfered edges. They look good, even after some dinging. A roundover will “show” the dings a bit more because of the smooth surface tangents with top and sides. By creating a “broken” (chamfered) edge, it will look intentional even after additional dings make their mark (and dings there will be!)

Another good reason to chamfer the edges (besides lessening the pain of hitting yourself off it) is to allow a surface at the corner for your finish to adhere to.
If it were mine I’d rub the edges with sandpaper.

Have your say...
