I'm going to show how I make a Dovetail Spline jig, but I'm making 2 of them. First one is for the main dovetail an the second one is for a Inlay Dovetail
First I pulled out a scrap piece of Baltic Burch Plywood 3/4 inch
I'm going to making (2) X 7 Inch rips on the scrap
Next on each piece I'm going to make (2) 7 inch cuts an (1) 11 inch piece
Next on the 7" x 7" pieces I cut a 45 degree angle on one side,
As you can see in the picture there is a recess cut across the grain on the 11" piece. Here is why all corners on the project theses jigs are made for are sharp corners so I cut a recess in the center across the board I only went in about 1/8"
Next on the C/L I marked out for (2) 1" holes these hole are 3 1/2" from the recess on each side
Next thing I did I found some scrap Oak an cut some 45s for support latter in the thread
Now for the best alignment for this jig is to take it to your project an clamp the 7" X 7" pieces to the corner top an bottom with the long end of the 45s touching the wood , bring it close to the corner
While it is clamped check an see if the top plat sits nicely on the 45s, if not adjust until it does. On mine it looks great so I took the pieces off an put some wax paper on the corner an reattached the pieces
Double check fit-up an adjust as needed, If you are ready put glue on the 45s an set your top plate on an brad nail it in place
