A method I have used to set up or mill an angle on a component is one I have
not seen described before. I have used it successfully to set up a machining
fixture to within ±2 seconds. (Angular dimensions run degrees, minutes and
seconds.) I set up the fixture and it was spot-on first time. What you have to
do is work out the drop for an angle over a specific length and then machine
a block to this length and depth. Then, after very lightly deburring the block,
turn it over in the vice and machine off the bottom of the block, which will be at
the required angle. The resulting block is usually called a slipper block. These
blocks are ideal especially for shallow angles.
