Here are some pic sand description of the process I use to make the arch and mouldings for the fruit stand .
In this case I used some hardwood flooring with the finish and the backside grooves removed which brings it down to about 9/16 ”.
I set up my sled with simple index pin and two index marks for left and right hand cut on the movable panel on the sled.
I use a 7 1/4” 40 tooth blade and the arbor tilted to 10 DEG.
The blade is set in height to leave about 3/32”of the board as a continues layer which will be the inside of the arch .
I make the first set of cuts using the index pin as a starting point and then move the sled panel which has the index pin attached to the right hand position and cut the next set of kerfs .
I build as simple jig to form the arch from the arch from some 4”x4”and a clamp from some timing belt and a threaded rod etc. The clamp is tightened with a cordless drill SET TO A LOW TORQUE SETTING which makes it fairly fast and eliminates a lot of clamps .
I put some red tape on the belt as positioning marks for the material to be placed .
The kerfed part and a strip of veneer which is the out side layer are glued up and positioned in the jig and the belt is tensioned pulling the arch tight against the form block .
After the glue has set for a few hours I fish the edges on the jointer and sand all surfaces .
While I was at it I also made some ornamental moulding using the same kerfing set up for a couple of boxes in the works .
