KKM and SVI hybrid/Island barrel milling

[jbauman915]

I've been using Schuemann hybrid barrels for my limited and open builds up until now.  Great barrels and frankly easy to mill them as you only need one straight cut 7/16 endmill.  The choices are only govt 5" and commander 4.25" though for the threaded hybrid barrels.  I'm looking at starting to also use SVI or KKM (if they ever come back on stock) island barrels.  Specifically so I can get thr 4.6 middy design going.  I cannot find any blueprints or instructions for milling the slide for them though.  What is the radius on the corners for them?  Does anyone have the plans or instructions for milling?  Once I had one I could spend forever figuring it out but I'd love to save some time on mill setup and programming and just get it done!

I made the inside corners at the back of the island .125" radius, all the clearance on the undersides will have to be done by hand. See ref pic for corner location.

 

.003"clearance on sides and .005" at the back.

Sorry, forgot to mention the barrel type, it is a KKM. I'd like to buy another one to put an open top end on my limited gun, but can't find one.

 

I was really impressed with the quality of the KKM barrel and don't want to stray from them for my next build.

Yeah I only use KKM barrels in my limited and single stack guns.  They haven't been available for a while with rib so I been using the schuemann barrels because they are available.  Appreciate the sketch!
