Hi.
Trying to have a tool made, went to a decent machinist with decent equipment and he gave up.
What and how would you suggest this can be done ?
Purpose is to make circular grooves 'gland' in bronze to lodge o-rings.
Source 'virgin tool' is a straight 3/4" carbide router bit to modify. Its dimensions are 0.750" o.d. ; 0.362" i.d.

Tried to do by hand with Dremel what the machinist could not (internal 0.480" diametre on sketch) but unhappy with results from tired vision and shaky hands
Left = 'virgin' tool ; right = modified to match measurements shown.
Edit: Is there router bits for carving o-ring glands on the market, istead or reinventing the wheel ?
