Through Hulls

I forgot my proper camera so I had to use my rubbish phone camera for this shot.  It didn't come out too bad considering.  Anyway, the special grooving tool is rigged up in a boring bar holder and I am about to put the “O” ring groove onto the inside of the bore.  1/4 inch down into the hole on both sides.  I wound it down the hole into the right place, switched the machine on (speed 625 rpm) and carefully reversed the tip onto the inside of the bore 2mm down.  Worked a treat.
