MK Control Horn Installation

Step 7

Now we need to make the hole for the dowel. DO NOT use a drill bit or hand drill for this!  The only acceptable method for best results here is to use a drill press. If you don't have one, get all of your surfaces and dowels ready and then take them somewhere where you can borrow a drill press.

Your "bit" will be a sharpened brass tube. I use 1/2" diameter dowel and thus 1/2" diameter (OD) brass tube. Carefully sharpen the inside edge with a sharp hobby knife, and file an edge on the outside. Cut the length as desired, 4 inches is plenty.

Now chuck the brass tube into the drill press and adjust the table to be perpendicular to the tube. Put the control surface ON THE SHUCK - the leading edge should be vertical to your flat surface. Now very carefully align the brass tube with the circle you marked on the control surface.

Look at it from front and side, and make a "shallow" start. If it's not in the right place, move your surface and try again. When you get it right, use light pressure to continue the cut through the entire block.
