THE might of man against machine will be tested on Father's Day this Sunday, when a Plymouth strongman attempts to pull a 14-ton steam engine at Dingles Fairground Heritage Centre near Lifton. Dave Glover (pictured right) will attempt to pull the 'mighty engine' which was built by Burrell's in 1924. Dave, who recently pulled two double decker buses on Plymouth Hoe, was in training for the event last week. The charity event will raise money jointly between Children's Hospice South West and the Fairground Heritage Trust. As well as engines in steam, vintage fairground rides and 'old time' games such as the coconut shy will be on offer. The Heritage Centre also houses a collection of fairground art. The doors open at 10.30am.
