If you have access to a milling machine, that would be the quickest way.
Otherwise, drill a hole at each end of the slot and "connect" the holes
with a jigsaw. Lay out your lines, and it will be pretty easy.
One would cut those slots with a mill, basically. Manual or CNC, depending
on what you had and how many you were making. You could just also cut them
with a drill and a jig saw, if you were willing to take the time and file to
fit. you could cut them with a hand drill and a file, if you were
power-tool deprived and had a lot of time on your hands.
You could cut them with a plasma cutter and file to fit. You could punch
them, I suppose, but not in a typical home shop...
None of the above. Typically these are cut with a high speed steel 2
flute helical end mill held in a vertical (Bridgeport) milling machine.
In a pinch, Johns drill and jig saw method sounds pretty good.
A picture below shows a 1/2" thick
Could he drill a series of holes and then finish off with a hand held router
with carbide bit? If he can do this, he'd be able to get a very nice finish
(when compared to a jig saw'd hole).
you can also drill one hole on each end of the oblong and then proceed
to drill a series of holes between them by overlapping the drill holes
,that when you are done it will look like waves on both sides of the
oblong ,then take
a hand file and file them down make sure you had set up guide lines
ahead of time so you dont go too far with the filing ,which means set up
2 lines for the width 2 lines on the end for the length and 1 one line
right down the center
for your drill guide . It's
best to use a drill press if you got one for this method ,but you can
use a hand drill but be extra careful of catching of the bit when doing
that and always make sure your piece is secured ,it takes awhile to do
can get it done by yourself and without expensive equipment .
If in a hurry and dont have a milling machine take it to a machine shop
to do and explain and if possible draw a picture of what you want .
If you are asking how the original were made my guess would they were
Water Jetted. If you want to make one well, hmmm. The idea of
drilling holes at each end and cutting with a jig saw sounds pretty
good especially sense a Water jet, Laser, or punch (that big) are not

I drilled a 1/2" hole on each end of the
slot and used a jigsaw with a metal blade
to connect the holes. I also used wd40 while
cutting to keep the blade clean.
I then used a metal file to clean it up a bit.
