Back in January, John Kohnen and I were discussing scarfing jigs and I showed the jig I used on my table saw. John said “I've been thinking about a jig (or would it be a fixture? I never can keep that straight) for using a handheld circular saw, so I don't need to clean such a wide behind the tablesaw”
I have been under house arrest these last few weeks and I have not been allowed to work on the Tolman so I am working on the long neglected Puddle Duck Canoe.
I will need to scarf some parts for the gunwales so I decided to build the Kohnen Scarfing Jig.
The jig would use my track saw and be portable so I could take it to RiversWest to cut the splash rail for the Tolman.
The jig cuts a 1:8 scarf for material up to 1 inch tall and 1 inch wide.
Since I cut both pieces at the same time the jig opens up to 2 plus change wide.
This was arbitrary since and I can change it in the future.
The design goals were to:
1. Not hurt myself
2. Not hurt the blade by cutting any screws.
3. Easy to setup.
4. Keep myself busy.

I clamped some scrap in the jig and gave it a whorl. As you can see from the pictures the jig worked very well.
