Hercus 9" elbow oiler gits - thread type
Hi all,
I purchased an elbow oiler git, the toilet seat type, to replace one which appears to have been sheared off many years ago by a previous owner on the apron. Initially I tried to see if I could unscrew the remains of the old one by using a punch or drift to get it rotating but it wont budge and I stopped before I made a dogs breakfast of things.
Potentially I could use an easy-out but I am concerned with it being very soft metal this might just chew up and make matters worse. I believe the best course of action will be to drill it out and re-tap the thread. The only thing is apart from measuring the new oiler to be 26tpi I don't know the other dimension. I can't seem to find any info on it either. The new one appears to be a tapered thread. I don't have any taps anywhere near that size with a fine thread so I will have to purchase one for the job.
Appreciate any help if somebody knows!
Cheers,
ratters
