Making a Boot Jack

Cut a piece of 1x6 14" long and another 3" long, trim the width of the 3" long piece so its 1/2" narrower than the main board (it'll look better when you taper and round the edges of the main board).   Draw a center line down the bottom center of the main board (2-3/4" from the edge).   All 1x6s aren't created equal, they can be from 5-1/2" to 5-1/4" wide so adjust the center line accordingly.   On the center line, make a mark 4" from the right end and draw a 1-1/4" circle centered on that mark.   Mark a spot 1" from the left, on the centerline, for the "hanging hole".  
Using a square draw a transverse line across the bottom of the main board, 8-1/2" from the left end and another 9-1/4" from the left end, these will mark the position of the bottom support.   On the right end of the board make marks 1/2" from the top and bottom edges.   From each of these marks, draw a line to the center of the 1-1/4" circle then, sarting at the edge of the 1-1/4" circle, draw lines that intersect the last two lines 1" from the right edge (see pic), this will form the boot heel grabber.   On the left end of the board make marks 1/2" from the top and bottom edges.   From these marks draw lines to the same corner on the right end, these will give the tapered shape to the main board.

On top of the board, and using a square, draw a transverse line 8-7/8" from the left end (hanging hole end), and mark two screw holes 1" on each side of the center line, (these will mark screw holes to hold the bottom support.
Drill the 1-1/4" and 3/4" holes.   Saw the dotted lines for the boot heel grabber (using a bandsaw, jigsaw, or even a coping saw).   Using a 1/4" round off bit, round all edges on both sides of the main board (including the inside of the holes and boot grabber) and the bottom support except the top edge of the bottom support (goes against the main board).   Drill and counter sink the two screw holes down into the support matching it's angle.   Glue and screw the bottom support to the main board, I clamp the bottom support while drilling and screwing it on to hold it in place.   Sand and paint.  

Options:
1. Bevel the top of the bottom support so the support stands straight up and down (see diagram).   You must drill the countersink holes straight into the support.
2. Route or plough a 1/8" deep dado in the bottom of the main board for the bottom support.   It must be at least 4/5" wide.
3. Glue and tack a leather strip in the mouth of the boot heel grabber.
4. Glue a piece of sandpaper, or leather, or rubbery shelf liner to the top between the hanging hole and boot heel grabber so your other foot has better traction when using the boot jack.
