I finally finished the last stretcher today, it was twisted and slightly bent, that is what I get for taking so long to build this thing. Due to the wood movement, it took a little longer to tune the fit of the joints.
I did a dry fit of the base assembly and after taking a few measurements, I am afraid I might not be able to draw bore the joints together as originally planned.
With the base clamped up, The measurements show there is about a 1/2" difference btwn the distance btwn top of the legs and the and the mortises in the bench top. I am worried that the difference will not allow the draw bore holes to line up once the top is installed. So, I am thinking about gluing the stretchers to the legs, clamping them loosely, then glue the top on and then go back and just drill/drive pegs straight thru the legs and tenons, no drawbore.
Let me know what you think or if you have another suggestion.
