Started work on the "T" piece.
Used a 16mm brass rod for it and carved out the middle part using a parting tool I last used to make the Kiwi crankshaft.
Cleaned it up using a left hand and right hand turning tool.
Left a centre mark on both flanges for a later operation.
Marked the centre of the middle part with the help of an edge finder.
Using a 6mm slot drill cut the hole for the other part of the "T" piece.
