Hey Fellow Lumberjocks,
I thought I’d take a minute and share my latest shop-project. I know that there are many ways to sharpen an edge, so I’m not attempting to weigh in on the discussion of which is best, etc. I had researched a bunch of them before deciding on the method I wanted to invest in. A friend in the local Woodworkers Club got me interested in this one, so I built an outfit for myself. For the most part I didn’t rethink much…just copied his. For more info, see Mark's website my “credit where credit is due” clause.
As the title would indicate, it’s based on the Scary Sharp methodology. 1/4” table top glass, 3M PSA-backed Micro-Abrasive film (40, 15, 5, & 0.3 microns), etc. The idea behind this setup is that the triangular block of wood that serves as the angle guide slides along the glass up to the point of hitting the film. Back-n-forth, back-n-forth. A little mineral oil and away we go. Quite clean compared to the water stones I was tempted to buy in to…and cheaper than the diamond stones I REALLY wanted to buy in to. Also, the triangular nature of the guide block easily allows putting a camber on the edges.
Anyway, my project consisted of building a box to house it all, as well as getting all the supplies etc. to get started sharpening. I’ve got the glass sliding in slots cut in the sides and a cover for the front that will keep that sawdust outta there when not in use. Still needs handles…it’s a bit heavy, so I want to get some good ones that won’t fail while carrying (shattering glass will ruin my day).
Also added an extra sheet of glass beyond Mark’s guidelines. What I do with that one is put a piece of mylar film on it and use that with the abrasive grit you see in the bottom in one of the pics. I got the mylar and grit from Lee Valley for a decent price.
Not seen in these pics is the really great little “Brock MagiScope” microscope I bought for $40 off of Craig’s List yesterday. It’s fantastic…had I not had it I would have assumed my edge was sharp long before it really was. Had a to work quite a while longer to get rid of the massive chip in my plane blade that I could not have seen otherwise (but likely would have left a mark on my work).I don’t recall exactly how much I spent on this, but here’s an attempt to ballpark it:
- $30—5- 1/4” table top glass
- $35—3M Abrasive Film
- $40—mylar and abrasive grit
- free—wood for project…scraps mostly
Hope this helps someone get closer to sharpening their tools regularly…sharper is better…and safer.
Thanks for looking!
