Ok a couple of busy days, probably gonna take a day off today to be with the family.
Here is one side of the top brace scribed for routing the curved side of the lap joint.
and here it is after routing, the edge was done in four very careful passes with a 1/8th bit and then the rest was hogged out with a 3/4 straight bit after this pic. After doing six of these my shoulders were pretty tight.
Then I took to it with chisel and file and very slowly snuck up on a nice tight fit.
Next I cut the curves at the top of the uprights on the bandsaw and then drilled out the holes top and bottom on the drill press. The everything got a slight chamfer with the router and corners cleaned up with a chisel.
Here is one of the three frames dry fit and ready to be glued up. The nice thing about the half laps at the top is they hold everything together really well… almost feels like I dont need any glue (but I will).
