[QUOTE="OKC_Gunsmith, post: 2133734, member: 28420"] The broaching process as referenced here refers to shaping the metal in a way that is not easily formed by conventional machining processes. E.g. tight corners / sharp internal lines. If you look at earlier pictures in this thread you will see the mag wells were initially oval shaped and in the pictures above they are shaped to accept magazines. Check here for a video of the broaching in action. [url]https://www.youtube.com/watch?v=erO7RMP_GzE[/url] Soon. I've got a few goodies planned in the upcoming months, just need to get this under my belt first. On a side note, the measuring arm shipped today, so I should have pictures shortly. [/QUOTE]
