Difficulty: Easy (just like the name)
This is a bit overdue, but decided that it deserves a review!
Used on the Anderson Manufacturing 80% 7075
Tools used:
Easy Jig
Rigid Router 1.5 HP
Dewalt TiN coated drill bits
Mcmasters 3 flute TiN coated end mill
Ryobi power drill
Home Depot drill press vise
WD40
The build of the jig is made for the regular joe. With no experience with milling what so ever the project amazed even myself. The assembly of the jig is pretty self explanatory. And drilling/milling requires nothing but patience.
Drilling: 15-20minutes
The first initial drilling of the 3/8th holes will be taking majority of the material out. With body weight pressure, apply a good amount of force and frequently clear the drilled material from the holes and bit. Although it's not cutting fluid, I used WD40 sprayed into a cup so I can dip the bit prior to drilling any holes.
Milling: 2 Hours (T6-7075)
IMPORTANT ***TAKE YOUR TIME AND COMPLETE EACH PASS***
With 7075-T6 aluminum take 1/4 increments of each hash mark
I waited till the 2nd to the last hash mark to fully mill out the pocket spraying WD40 on the end mill. This part will be taking a lot of material out.
Keep working the pocket till you bottom out on the main pocket template, follow the same pattern for drilling and milling the Trigger pocket
Finish off with drilling the holes for the Hammer, Trigger and Safety using the bit sizes referenced on the side of the Jig
Test fit your parts and finish off!
