I have been slowly getting into woodworking and decided I would start with a few small project to build my skill. So i looked in the normal places for projects and plans. I subscribe to Chris Schwarz webpage and often receive his emails about the things he is working on. One of his emails was about creating your own marking knife out of a drill bit.
I decided this seemed easy enough and was a pretty good skill builder. So with an old drill bit and some simple tools I set out to build a marking knife. A marking knife makes measuring and cutting wood cleaner and more accurate. So it will be a great addition to my growing inventory of tools. Enjoy
Step 1: Tools and Supplies
Drill or Drill Press
Dremel and assorted accessories
Some sort of finish
Some sort of wood
A spade bit
Step 2: Pick your poison
I had a few old spade drill bits laying around so I had a few to choose from. Also some choices to make. Did I want to attempt a single bevel of a double bevel. I opted for the single out of ease and a smaller bit to start with.
Step 3: Cut the bit and shape
I decided on a single bevel and picked an angle at random to cut the bevel. To cut the bevel I used the cutting wheel on my Dremel tool. It wasn't to hard to get through the metal. I took my time to insure the metal did not get to hot. I was worried about effecting the blades ability to maintain a sharp edge. I then used the small sanding drum for my Dremel to sand the shard edge down. I also used a stone wheel on my Dremel at the end, but I didn't get a photo of that.
