In a separate move, M&M Timber has launched its own incised post product, the Agricised fence post.
Tweddle Engineering in Cumbria is launching the Excalibur incising machine for square sawn timbers and the Sidewinder for timber rounds later this month. Both machines were designed with a compact footprint to withstand sawmill environments and handle common commodity sizes.
It is the latest in a number of incising machines that have been developed in answer to a spate of fence post failures.The equipment cuts a hole pattern into the posts that improves penetration of pressure impregnation timber preservatives.
The Tweddle machines were developed in partnership with Lonza Wood Protection.
"Both machines deliver a consistent incising pattern through an advanced head control, even across surface knots," said director Derek Tweddle.
They join two existing UK-made machines – the Hedgehog and Porcupine, developed in partnerships with sawmills, engineering companies and Osmose.
BSW Timber and machinery manufacturer AV Birch launched the Porcupine last year. AV Birch handles wider sales and service.
In February Osmose Timber Technologies signed an agreement with Walford Timber to take over the sales and marketing of the Hedgehog, which was developed with a Hertfordshire engineering company.
Its first machine was sold to North West Timber Treatments and another has come on stream at M&M Timber, which has launched its Agricised fence post, featuring incised timber on the lower section of the product.
"This process represents a major investment for the company," said M&M commercial director Andy Hodge.
