Re-machining the crankcase mating face on an extensively weld repaired prewar Alvis cylinder block.
Not our usual line of work, but we have the Huron MU6 Universal milling machine for this very sort of thing.

The A-M Vantage Virage pump is now a lot happier! The body was bored out to take a more readily available seal from a well-known 5.3 V12, quality NKE Austria bearings, the impeller was gently warmed to assist in getting the locking screw to line up and find its threads, its turned out nicely with a healthy amount of seal drag.

A rather unhappy coolant pump from an Aston Martin Vantage Virage (the 5.3 twin supercharged one)
We have seen one before so we know the score on these, this one probably couldn't be heard over the engine and exhaust noise!

Not our usual line when it comes to specialist automotive repair work*
Steering box from the ex-TWR BMW E12 racing saloon circa 1977, actually a modified E9 (CSL) ZF/Gemmer manual unit, presumably chosen for its higher rate.
Basically irreplaceable, prior damage due to poor workmanship sometime in the last 40+ years.
Damaged needle races removed, outsourced hd metal laser welding to repair one pitted worm bearing track and then reground by us, badly turned (tapered!) sector shaft also reground parallel, solid bronze bushes to suit.
Reshimmed and ready to race again.
*Pre 1960's Burman Douglas bronze nut steering is our speciality, we hold all the original Leone tooling, casting patterns etc with the exception of Series 1 Land Rover, but we can get those on request.

Warning to all small engineering businesses.
We have just had to confront and eject someone from our premises who came to the door unannounced, dressed in suspiciously clean hi-viz, with a cockandbull story about a broken down road scanner.
They are just trying to acquire high value materials: carbide, brass plate, stainless, anything.
They will get argumentative and noisy, play the victim and try veiled threats.
Don't let them in.
Small black Caddy type van, might have been a 19 plate.

We were very pleased to renew our relationship with Network Rail S&T this summer with the turnkey supply of 50 fence bottle switches (aka chalk fall detection) in cast phosphor bronze from our own patterns.
11tpi threads, brass and acetal internal parts with silver plating to electrical contacts, brass and steel springs, all UK sourced and made.

Its that time of year again when the work experience requests start to come in.
Whilst we would really like to engage with keen school pupils and college students to grow their interest in practical engineering, we simply aren't big enough to have the resources to help.

To clarify that we have no connection to Holman Bros late of Cambourne, Cornwall (manufacturers of mining equipment and compressors) or their successors Compair, Broomwade et al.
We simply happen have to one of their spanners about the workshop.

A slow burning project recently completed for a Ferrari specialist. A pilot batch of Ferrari 400/412 water pump covers. Casting pattern developed from a damaged sample by us, sand cast and heat treated in LM25TF by Harling Foundries and fully machined by ourselves.
