because he kept trying new bits until he found the one that was faulty and really it was his travelling to and fro on several occasions.
I told the engineer that I didn’t want to throw good money after bad on an old machine unless they could fix it quickly and cheaply then the onus was on the engineer to give me two quotes before he started.
One to supply a new machine and another quote to repair the old one.
Accepting that the old one may have been an unknown quantity he should at least with his experience and expertise given me the benefit of his knowledge
that's great, many thanks
