The job was several height adjusters for Dickson tool holders destined for a Harrison M250.
25 mm bright bar on a Colchester Bantam with HSS producing a long curl of swarf.
I was watching the build-up of swarf below the bed and slowly filling the bed between the ways.
I thought "must stop and clear all that after this cut".

Too late: in a split second all the swarf I could see was dragged up by the trailing swarf curl and wrapped around the bar.
There was a spray of small loose bits, some into my face.

No damage to me (safety glasses), the lathe, the shop or the job.
Just embarrassed that I could be so lax.

Yes, you were lucky your tie did not get hooked up in that lot.

Lot to be said for a chipbreaker groove ground into the top face of HSS tools.
 
Judging from the size of the strings, you need more feed per Rev. start with .010 then increase from there. Use the radius of the nose on the cutter to get the finish, rather than decreasing the FPR.
