My day is planned out

[AllenM]

I'll be fitting 1911 barrels most of the day.

3 guesses at favorite barrel manufacture...

 

[Mongo59]

Now that is a tough one...

 

[AllenM]

its early I am not in a rush, here are a couple pics of the process

This slide is getting two barrels fit to it, 9MM and 38 Super.

First thing I do is stone the slide hood to check for and smooth out any tooling marks. then measure slide and barrel hoods


.373 is a snug fit on the slide


Barrel #1



Barrel #2



you cant just remove material randomly from the sides of the barrel hood. they need to be measured to determine how much to remove from each side.

This is the system I use.
Mounting the slide and barrel horizontal in a vise and measure to left side of the slide opening and the right side of the barrel hood tells me how much material to remove from that side of the barrel hood.
Then measure total width of the barrel hood after removing the right side material and the difference is how much you need to remove from the left side of barrel hood.

I found this one interesting, Both KKM barrels and hood width is pretty close to the same on both but the amount to remove on this side of the hood is different on each barrel.
It makes no difference since the hoods are oversized and both sides still need cut.

You are a guy I would love to hang out and watch you work. You teach so well.

My brain hurts looking at this …… I’m sure I could learn but I don’t know if I can learn patience lol definitely amazing skill patience and experience doing these projects.

 

[AllenM]

Next step
Material removal



now measure and remove material from left side of barrel hood

Barrel 1


Barrel 2



.373 was the goal which will allow for me to stone for final fit
Got pretty close



When done cutting the hood like this the lower barrel lugs are centered between the slide rails




measure and cut hood length. this is a tool from EGW that measures the inside length from the breach face to the rear barrel lug



Then just compare that to the barrel hood and trim barrel hood



ignore the .025 that was a left over measurement

 

[AllenM]

Hit my pic limit on last post.

Both barrels are now in battery with lower lugs in center of slide

It's not rocket science but patience and time for certain.

Thank you

Looks harder than rocket science to me!

Take a left on 150 and a right on 37. Then keep driving a couple hours.

Do you need a passport to leave Crawford County or can you take the backroads to avoid the man?

 

[ditcherman]

Actual machining is the easy part. The logic used to get the correct results is the hard part. And the machining’s still not easy.
You make it look easy and end up with beautiful work!

 

[AllenM]

Last thing on this slide for the day, then I need to do the ones that I have the Frames for.

Whats going on here.. Oh yes custom length slide


Removing excess metal



Much better

Passports don't do no good in Crawford, why even the man don't know how to read...

I don't know the difference from rocket surgery and brain science...

What brand of disc grinder are you using? Obviously, my dewalt isn't up to the task.

Oh yea, you have to go with Milwaukee

A friend shared this with me and wow ... that's some beautiful work.
