Just a few things that I've picked up along the way.
A short piece of 1-1/2" painters tape is just the right size to protect the lower while performing the machining operations. 
A 1/4" clevis pin not only works well to secure the front of the jig, it also makes a handy tool for installing the pivot pin detent and spring when the time comes. 
It is very important to keep the chips cleared out while machining. Unfortunately I was born with only two hands (both of which are kept firmly around the router) so I came up with this handy, dandy vac attachment out of a piece of 1" copper pipe and some 1" hose from Lowes. 
Just be sure to keep it way away from the machining area. I secured mine with a copper pipe hanger

While on the subject of drilling, I have a certain order that I like to use. Imagine the holes in the drill guide numbered 1-9 top to bottom.
I like to start out with Hole number #4 which is the only "A" hole. Then I drill #8 which if using a gen ll receiver will be the only "B" depth hole. Then set your drill to "C" depth and drill the rest of the holes in this order #1, #3, #2, #5, #7, #6. You will not be drilling #9 if you have a gen ll lower. By doing them in this order you will keep any tension equal on both sides of holes #2 & #5. I feel that it is worth consideration because those two holes are extremely close to their neighbors. |

I did somethings similar for the chip removal using a shop vac crevice attachment, some painters tape, and a bungee cord. There are pics of it in my thread. Which reminds me I should take a pic of the inside of my mini cyclone to show how much chips you produce completing an 80%.
Your idea for drilling kind of mimics mine. I do the trigger slot hole, then all the 3/8" holes. My last 4 lowers I didn't even touch the rear two holes. I another lower that I'm going to try just driving the trigger slot hole and then going straight to the router with. Wayne suggested it. Posted Via AR15.Com Mobile |

Here's a question for you... When I received my new Modulus HD jig it didn't come with any printed instructions although it was very easy being familiar with the original Modulus jig to figure out how to put together. Looking at y'all's web site I may be blind or something but I'm not finding where I can find directions or videos for the HD jig, although I find the ones for the original jig easy enough. It would be great to have updated instructions and videos for the new jig since a few things have changed, for the better. I really like the way the drilling and routing plates fit into the jig from the top now, it is a lot easier and faster to change them than it was with the original jig.

Thanks, that was what I was looking for... Either I'm completely blind or they revised the web site and made the links to the HD instructions easier to find... Or maybe I had an old cached copy of the web site on my computer or something... because looking at it now, it is there plain as day... |
