Press method two:
Drill all the
holes in your board using a 3/32 drill bit. I use plain old jobber bits,
they work just fine. The drill should be run at the fastest speed that
it can go. See photo A
Install all the lugs into the drilled holes. Be careful with the board
so the lugs don't fall out. See photo B
Mount the tool in
the press. Mount the pointed tool in a metal plate on the bottom. The
flat metal plate is then bolted down to the base of the drill press.
The tool with the hole gets mounted in the chuck. You line up the two
tools so that the pointed tool comes down and hits the center of the
hole on the top tool. Tighten down both tools so that they are lined up
correctly. See photo C
The two tools are
only far apart enough to slide a lug in and have just a bit of room on
the top and the bottom of the lug. See photo D
Move the board between the two tool pieces and line up a lug in the
center of the two tool pieces. See photo D
Pull the board straight up so
that the lug enters the hole in the top tool. See photo E
Pull the handle of the press down
so that the two tools come together. Make sure you keep a slight upward
pressure on the board so that the lug is pressed flat against the top
surface of the board. It does not take very much pressure to swage/flair
the lug. They are soft brass inside with a nice plating on the outside.
They are not steel. See photo F
Now that the lug
is firmly seated in the board, you can let go of the press handle and
then push down on the board and move it to the next lug to be pressed.
The back of the lug will have a nice swage or flair that holds it firmly
onto the board. See photo G.
