More about me:

There was never any doubt that I was going to be an engineer; and now I are one! School was a waste of time, apart from 'O' level metalwork and physical geography. University was much more interesting. My first degree was in electronics, at Liverpool, as part of a thick sandwich course with MOD (Ministry of Defence). That was followed by a Ph.D. and several years post-doc research into pulse compression radar signal design and signal processing theory at King's College, Cambridge. After leaving the world of academia I've worked in all sorts of areas; active noise control, high end motor racing, electric vehicles, integrated circuit design, mobile 'phones and power electronics. After being made redundant yet again, I've been self-employed for the past 14 years.

First lathe was bought when I was 13, from an old building in Bedford that was being re-developed. It was a Logan, quite rare in the UK, and almost certainly came over in the war as part of lend-lease. I was also given an old pillar drill. With help from people in the Bedford MES I got part way through building 'Mona', a LBSC 0-6-2 tank engine. Both machines were sold when I went off to university.

After buying a bungalow with a double garage 15 years ago, I've been able to set up a modest workshop. Got the usual stuff, gap bed lathe, three milling machines (vertical, universal horizontal and CNC) and a shaper. Latest additions are a Britan repetition lathe and assorted Pultra lathes. For grinding there are surface, cylindrical and tool/cutter grinders. Sheet metal tools include a power guillotine, box and pan folder and flypress. For heat treatment there’s an oven, propane torch, and oxy-acetylene and TIG welding sets. I'm about two thirds of the way through an Economy hit 'n' miss engine and I have a kitchen full of parts and castings for two 4" scale SCC Burrells.
