    The Clone Wars... XM3 EFR Mount stuff

    There is an ever-growing pile of stuff that I am starting on. The most current project is a dissection of an M40 base and ring set. We took delivery of this today as well:

    Here's where I'm at thus far, and I'll share what I plan to do about the rings attaching to the base. These rings begin life on a lathe. They are profiled and parted off. Then it's vise work and pretty simple. My guess is the upper and lower portion of the ring is made all at once. The two...

    Status: Base fundamentals are modeled. Now for the ring package... I have a solution. More on that in a minute. I have to model up the rings first. I'm more or less updating this post in real time so bear with me.

    Tangent corners.... The same part features, but look closer as the arcs are no longer tangent to the right vertical feature.

    So, down the rabbit hole, we go on this. If we take a big (BIG) step back and look at this thing, some small but key details reveal themselves. Diving a bit further, I start to think about the gun industry as a whole and how it has been rather cottage for a very, very long time. If you...

    We've been hinting around at this for the last few weeks. The artifact parts have arrived and I am about to start with the modeling work. I feel like I'm holding something from a Raiders of the Lost Arc movie. So it begins. I'll post some additional photos as I progress through the autopsy.

    Oky doke folks! I had my friend from down the street (a gorilla that used to run the RCS) take a look at them. Thumbs up so we'll start boxing stuff up.

    Pacific Tool & Guide...The love keeps coming

    After cleanup in the blast cabinet. Adhesion up front is good. Creep on the rear reveals 100% adhesion across both parts.

    Pacific Tool & Guide...The love keeps coming

    I have a few T&T jobs to catch up on this am so I snapped some photos to show what's involved with this service. Parts being sterile is a big deal with this. No traces of oils, solvents, residual blast media, solder, paint, or any other funk can be present. Otherwise the weld quality goes...

    EFR parts have landed! Quick question for you guys: The original that I have used socket head cap screws. I happen to have some screws that are the same size, but with Torx head sockets. Stick with the Allen Key or do you want the torx heads instead?

    UPDATE: 7.11.2023 No parts came in yesterday. We are hoping for today. I'm going to start a new thread regarding this. It'll be up shortly.

    Pacific Tool & Guide...The love keeps coming

    Replied yesterday. I'm throwing it in here as there's a portion of this that might help others when/if they experience the same thing. (joint failure) I can knock this out pretty quickly. I still like to have the original barreled action here to ensure I get the PE timing correct. The biggest...

    Canted action/scope rail (side to side)

    FWIW: There are several things here that lead to where you are now. In a machinist world, it is called "tolerance stacking." Questions that immediately come to mind: Receiver guard screw holes squareness to bolt lug raceways Scope base holes squareness to bolt lug raceways Scope base radius...
