STEP 11
Continue taking deeper cuts by adjusting the end mill using the depth
gauge on the Rear Shelf Pocket Template #06 labeled MAIN. For 6061
lowers increase the depth of the end mill incrementally 1/4 to 1/3 notch for
each pass until you bottom out the end mill inside the depth gauge. For 7075
lowers increase the depth by only 1/6 to 1/4 notch. Each time, start inside
one of the 3/8” holes and work from the middle out in a clockwise direction.
(Each image in A-D shows a 1/4 notch or hash mark incremental move.
For the final pass, set depth to very top edge of gauge as shown in E.)
WARNING:
On the last two passes before getting to the bottom, the end
mill will not have a pre-drilled hole to start in. To prevent the end mill from
jerking when powering up the router, hover the router slightly above
the template and power up the router without the end mill touching the
lower. Then, very slowly, lower the router while maintaining a firm grip
on the router. For the final pass, the end mill depth is set so the end mill
is past the last notch and touching the top of the depth gauge.
When this process is complete, you’ll have the main trigger pocket milled out
and two rear shelf holes drilled out.
TIP:
Keep the jig and the lower clear of chips during the milling process for
best results. Go slowly and adjust the depth back a 1/4 notch if necessary
if you hear excessive noise or feel
excessive chatter.
NOTE:
If your lower came with the
rear shelf area milled out, you do
not need the two rear holes drilled
as shown. The front trigger pocket
does not need to be connected to
the rear shelf / lug pocket.
