Turbocharger Casing from Stockton Castings

t15154The picture shows two big turbochargers of the type used in large diesel truck engines, made by Holset Ltd in Huddersfield. In the early nineties I needed these for an experimental gas turbine, but working at much higher temperatures than usual. Super strength cast stainless steel would have to be used for the casings. We were told that the only company Holset trusted with “specials” of this type was Stockton Castings, in Ross Road, off Portrack Lane.

We visited the company, coming up from London, on behalf of our bit of British Gas R&D. We were greeted by the owner, Mr Wolverston , (I understand), a real gentlemen. He would have been around sixty at that time. He greeted us in his little office, upstairs from the foundry. I remember him being very smartly dressed in a green suit. He showed us round and it was clear that this casting, which was somewhat complex, and had to be made to tolerances of less than 0.5mm, would present no problems. One of our team came up a few weeks later to see the job being done and it was a no fuss affair.

Has anyone any pictures of the owner or the company or can say what jobs they normally did?

One thought on “Turbocharger Casing from Stockton Castings

  1. My father worked there, after finishing at British Steel over the road, from about 1987 until he retired in 2002. From what he told me, the foundry used to cast a lot of turbos for Holset, manifolds for Cosworth, and many other one-off/short production run items. They had a separate pattern-making workshop so could do all of the production work ‘in-house’.
