The firm
Three generations, one postcode.
Hollowgate Precision has made components on the same Sheffield yard since 1958. What follows is the short version; the long version is on the shop floor and you are welcome to come and see it.

Sixty-eight years on Hollowgate
Jack Alderman started the firm in 1958 with two capstan lathes and a surface grinder, having served his time as a toolmaker at one of the big Sheffield steelworks and decided he would rather make parts than manage people making them. His son Peter took it through the collapse of the 1980s by moving deliberately away from volume and into work that needed a drawing read carefully. His daughter Ruth runs it now, from the same yard, with twenty-two people and six machines. Almost everything about how the work is done has changed — capstan lathes to offline-programmed five-axis, a steel rule to a Zeiss CMM in a temperature-controlled room — and almost nothing about why. About 70% of what we made in 2025 was for customers who have been with us more than five years.
What being an old firm is actually worth
Longevity is easy to put on a website and hard to make mean anything, so here is what it is worth in practice. It means Tom Fenwick has been making fixtures here for forty-one years and can look at an awkward casting and know how to hold it, which is knowledge that exists in no handbook and cannot be bought in. It means we have a shelf of proven programmes and dedicated workholding going back decades, so a repeat part that arrives after four years dormant goes back on in days rather than being re-engineered from scratch. It means we have made the mistakes already: we know which coolant strategy Inconel wants because we ruined parts learning it in the nineties, not because we read it. And it means we own the building outright, so we can keep one five-axis machine deliberately under-loaded for expedite work instead of filling every hour to cover a lease. That last one is the least romantic and probably the most valuable. The flip side, said plainly: an old firm can be a complacent one. We have four apprentices in the building against twenty-two staff, which is a deliberately uncomfortable ratio, because the average age of a UK toolmaker is the single biggest threat to this trade and it is not going to be solved by anybody else.
Route card
How a part moves through the shop
Four operations, in this order, on every job from a one-off prototype to a batch of five thousand.
OP 10
Drawing review
An engineer reads your drawing before anyone quotes it. If a tolerance is going to cost you money for no functional gain, we tell you at this stage rather than after you have paid for it.
OP 20
Programme and prove
Toolpaths written offline and proved in the simulator, then a first-off cut and measured. Nothing goes into a batch until the first one has passed.
OP 30
Machine and gauge
Cutting on the five-axis and the wire, with in-process gauging at set intervals. The operator holds the part, and the same operator holds the batch.
OP 40
Inspect and report
Full CMM report against the drawing, AS9102 first-article where the contract asks for it, and the measured data goes in the box with the parts.
The four people you will deal with
Lead
“I served my time down the road at Firth Brown and I am hard to impress about a shop floor. Theirs is clean, the machines are on ticket, and there are four apprentices in there. That last one is the bit nobody else in this city is doing.”

Every quote is read by someone who has cut the part.
Send a STEP file or a PDF and we will come back inside two working days with a price, a lead time and — where it matters — a note on anything in the drawing that will cost you money without earning it.
