Morris Commercial Head Stud Removal.

[T Creighton]

Does anyone know of any other methods for removing 70 year old studs?

I have four Morris E H engines in various condition and need to select one for a rebuild as I am making a start on the Morris Commercial C8 project that has been sitting in the “too hard corner" of the shed for nearly 7 years.
I have only just acquired enough parts to get the project going again.
There are only 2 blocks that seem suitable but I will need stuff from at least one of the others.
The engine re conditioner seems to thinks parts should not be too much of a problem but I have to take everything in to him to evaluate. It will be mix and match.
He needs all the studs removed from the block that we will finally use so I am experimenting with the 2 unusable blocks.
I have drilled some using a centering jig and will hopefully clean out the threads with a tap (7/16” x 16 tpi BSF) when I get hold of one.
I have put three runs of arc weld along the length of the exposed stud and then wound them out using pipe tongs with an extended handle and a lot of force, but although this worked on one block, with 7 coming out.
There was a plate on this block with a reconditioning date of April 1954 so these studs would have been replaced then.
On the other block the internal thread was damaged using the welder heating method as the stud thread froze up again halfway out.
Without any heating one stud just snapped off.
I am using the arc welder for heating as I got rid of my gas welding set due to the cost of bottle rental.
Thanks in advance.
Cheers, Terry.
