In 2006 the larger studios at the farm to which McKenna relocated enabled him to extend into fabricating larger stainless steel sculptural structures. The new facilities saw the creation of a
colossal mining figure, named 'Jigger' commissioned by the
Walsall Metropolitan Borough Council for a site in
Brownhills. This 5 metric ton type 304
stainless steel sculpture of a miner stands approximately in height, brandishing a pickaxe and lamp, a monumental tribute to the local coal mining industry of this industrial area. It became the biggest representational sculpture figure of a miner in the UK and a significant public artwork for that area of the
Black Country. It was named 'Jigger' after Jack 'Jigger' Taylor, a local coal miner, who died in an
industrial accident when the roof of the pit at
Walsall Wood where he was working collapsed, in 1951. In 2007 McKenna set up the A4A art for architecture studio sculpture foundry where he started casting his own bronze sculpture and statues. He also created a bronze statue
The Miner of Auchengeich as a
memorial in
Moodiesburn near Glasgow. McKenna's stainless steel sculpture of a 'Hovering
Kestrel' measures six metres across its wingspan by four metres high, sited on a building facade 14 metres high. The Kestrel was commissioned by the client for the Citadel Logistics Building on the
Black Country Spine route, near
Bilston in the West Midlands. The Kestrel concept for the artwork came about through design research work undertaken by A4A associate
Steve Field drawing on Natural History information on the former site. ==Sporting Sculpture statues==
