You might consider selling the barrel and buying a new Glock factory barrel.

That is a good tip for castle nuts. Applying heat causes metals to expand, cold causes them to constrict. Both techniques try to give some wiggle room to get parts to move.
Hi Smack! Welcome to INGO.
Building an accurate, reliable, and safe 1911 is a very rewarding venture, but also one that requires a lot understanding of the 1911 tolerances and how parts interact. Definitely spend the time needed in asking questions, looking at videos (some teach you what not to...
I use the blue loctite on everything. The purpose of the loctite is to keep the screw from rotating and working itself loose, not to cement the screw in place.
As for heating aluminum, I used a propane torch last night to heat an aluminum 10-22 receiver that was not willing to release the...
Measuring out the cut for the lower barrel lugs.
Took a quick look at how the thumb safety would engage the notch in the slide to make sure it was going to be OK.
Indicating the fixture prior to cutting.
Hand fit the barrel to the slide. Lock up is at .052 and there is no springing.
Hood length is spot on. Fits easily with no binding and at the proper length.
Yes. Width of the hood notch in the breech face is .376. Taking the measurements as pictured above allows you to know how much to take off of the right-hand side of the hood. Remeasuring the hood and subtracting the breech face width gives you the left side measurement.
I zero'd out the DRO and took a measurement from the right side of the barrel hood and the inside of the ejection port. That measurement is listed on the Z axis on the DRO.
After some measuring, I was able to calculate how much material was needed to be removed from both sides of the...
This 2011 is mine and has not seen much attention with other work taking priority, but I have some time right now to get the barrel fit. The barrel is a KKM in 40SW.
I measured the breech face with calipers, then double checked the measurement with a gage pin.

Made sure the trigger bow was flat and removed the high spots and polished.
Though I did not take a picture of of the process, I machined the trigger shoe to fit the frame with very little tolerance.
After the machining was completed, the sides of the hammer were polished to reduce friction. You can see the difference in the first picture where the sides of the hammer still have the dull finish from grinding and the second picture shows the surface of the granite plate reflecting on the...
