I got this down, ad do them so quick now, its not funny....

I like Fragola fittings the best. The trick is, use WD40 when threading them togather, and I use a unibit on the inside of the hose to get it to start on the fitting better.....Works every time. To cut it, get a really good set of the curved electrical wire cutters. The big set that look like a set of bolt cutters.

Put the nut on the line and move it down out of the way, tape the spot your cutting thru, the cut thru it with the afore mentioned cutters, ream the inside with a unibit, assemble onto the fitting with lots of WD40 and slide the nut up and start the thread it on by hand......more WD40, and put a wrench on it and tighten it up.
