Marshall big end oil pot.

Is the problem the thread on the central tube ,if so why not make up a new pipe,one way is to get length of brass hex ,put it in the lathe and drill a hole down the centre, and thread the ends, using hex allows the tube to be tightened with a socket spanner , most of these tubes have lots of mole grip marks where owners have tried to screw them in. Just made one this week for a Garrett.
