Alaskan Mill The standard bed length is 16ft but,
Some old, some new, and all very mobile. We take a look at what’s currently available. Alaskan Mill The Alaskan Mk III chainsaw mill is a method of converting timber into valuable planks and beams using an ordinary chainsaw. The lightweight aluminium frame fits around all makes and models of chainsaw quickly and easily and allows the user to break down a log into planks. There is no need to drill or adapt the bar. Correct chain sharpening and depth gauge setting is essential (whether you use ripping chain or not). A well sharpened chain and well conditioned bar will give smooth and easy progress. A ladder or straight piece of timber is used to square the top of the log. Subsequent cuts are then made using this flat surface. The main advantage of chainsaw mills is that timber can be milled on site. The system is very portable and there is only a small outlay involved in getting started. The disadvantages are that it is physically demanding work, cutting speed is slow and a lot of sawdust is produced. 01590 681259 www.alaskanmill.co.uk Davies Implements Ltd Davies Implements Ltd have been distributing the LumberMate sawmills, manufactured by Norwood of Canada, since August 2006, and have recently been appointed as importers for the UK and Ireland. Currently, Norwood manufacture two models of LumberMate sawmill, each with various engine options. The LumberLite 24 is a static unit with a 24” maximum capacity and a board width of 17”. The more popular model, LumberMate 2000, offers a 31” maximum capacity with a maximum board width of 24”. The standard bed length is 16ft but, with extensions that are available as an extra, this can be increased to 40ft. Available with three engine options from 13hp to 23hp, it can very quickly be transformed from a static unit to a road legal, mobile sawmill. Additional options include toe boards, lapside and shingle kit, log loader and rotator, sharpener and setter and a fast tow trailer kit. Available soon, the LumberMate Pro MX34 has a larger capacity of 34” diameter and 28” board width; again with several engine options. Additional information should be available in the spring. The sawmills are delivered to the end-user in a kit format, allowing the user to become familiar with the machine prior to use. The LumberMate can also be purchased built at an additional charge. The Lumberlite prices start at £2,750 plus VAT and the LumberMate 2000 prices start at £4,475 plus VAT. A free DVD and brochure pack is available. 01267 237726 www.daviesimplementsltd.co.uk Fuelwood (Warwick) Ltd The saw frame of the Lucas Mill from Fuelwood assembles around the log very quickly, no tools required, and is adjusted easily to suit both timber and site location. Until recently just two models were available – the 614 model with 6” cut, powered by a 14hp petrol engine, which is very light to move around and the more popular, and the 830 model with an 8” cut, powered by a 30hp Kohler electric start petrol engine. The recent addition of the Model 1030 to the range, giving a 10” cut, should ensure that there is a model to suit all applications. Setup of the Autotrek mobile sawmill is possible in less than 15 minutes. Demonstrations can be arranged and a free demonstration DVD is available. 01926 484673 www.fuelwood.co.uk Just Saws Just Saws, a division of Charterhouse Turf Machinery, are the European importer of the Hud-son Oscar sawmills. They currently import four models that between them meet virtually all foresters’ requirements, being able to handle logs between 18 and 36 inches (45 to 90cm). “We are seeing particularly strong demand for the 30in-capacity (75cm) Oscar 230,” said Just Saws Product Manager, Curtis Allen. “It lends itself to use both as a portable unit and as a static installation. Power on the standard version comes from a 16hp V-Twin engine, and the machine is supplied with two 2.1m (7ft) tracks.” All four Oscar machines feature a four-post design for maximum head stability and they can be supplied as a towable trailer package that enables them to be towed virtually anywhere. Prices start at just £2,700. Just Saws also imports a range of accessories to complement its sawmills. These include Wood-Mizer DoubleHard blades, blade sharpeners, tooth setters, log ramps and cant hooks. 01428 661222 www.justsaws.co.uk Loglogic The Loglogic Autotrek Mobile Sawmill has been used in many diverse applications, and has been in use with the British Army throughout the world. Powered by a 65hp diesel engine driving a hydrostatic transmission to the saw head, the Autotrek is equipped with 101mm (4”) wide blades with optional stellite tips to allow all timbers, including greenheart, to be cut accurately and efficiently up to 1,000mm wide. Setup is possible in less than 15 minutes and the integral loading forks and handling systems allow logs up to 3½ tonnes to be selfloaded, turned and clamped, all from one operator position. The heavy-duty, adjustable log decks mean that even larger logs can be loaded without worry. A simple to operate, digital measuring system is fitted with an LCD display of board thickness (with integral kerf allowance) and absolute height from log bed for both ends of the saw bench. The mobile version of the Autotrek comes equipped with twin braked axles with Land Rover wheels and tyres. Loglogic also supply a range of Peterson swing sawmills from the 8” (Left) The Big Mill Pro from Logosol offers a complete system for cutting valuable, over-sized and hard-to-move logs.

(Right) Pezzolato’s Timber Queen range can handle a maximum log diameter of 900mm. cut 24hp WPF to the 10” cut 27hp ASM automated sawmill. These circular saw based swing saws can cut logs up to 1.8m diameter, and with additional track can cut logs of unlimited length (6m standard). Quarter sawing and weatherboards (with optional attachment) are no problem and board widths up to 10” or double cutting to 20” wide (without turning the mill) are easily achieved. Peterson refined blade and tip technology gives faster, easier cutting and accuracy to 1mm. Single depth adjustment allows for faster sizing and together they enable the operator to get the most out of a milling day. Outputs range from 4 to 8 cubic metres a day on the manual mills, and up to 2 cubic metres an hour on the automated mills. With extensive use of stainless steel and aluminium components, the mills are virtually rust free and are fitted, as standard, with Honda engines with Kohler petrol and Lombardini diesel options. The mills have the option of upgradeable cut sizes and motors to suit most requirements and budgets. 01884 839999 www.loglogic.co.uk Logosol Made from anodised aluminium, the M7 portable sawmill from Swedish company Logosol is lightweight and easily handled by one man. Logs are rolled onto the mill from a log table with the working height of 55cm and lifted up to saw height by turning the hand-operated crank. The M7 utilises a thinner guide bar and chain, which means that the cut taken is only slightly wider than the one taken by a circular saw. The sawmill is run with an ordinary power saw of a minimum capacity of 60cc. The saw can cut at 5 metres per minute on a 6 inch thick beam. If the chainsaw is replaced by a Logosol bandsaw, up to 16 metres per minute can be achieved. The standard length cut is 5.5 metres and recommended log diameter is up to 60cm. The cut is accurate and the surface remarkably smooth. Logosol estimates that one sharp chain will saw approximately five normal sized logs before it needs resharpening. The M5 model is a refined version of the original Logosol sawmill, first introduced in 1988, and the most sold model of all Logosol sawmills. Although the M5 lacks some of the features of the M7, it is an ideal choice where output is small. Logosol also offer a complete system for cutting valuable, over-sized and hard-to-move logs with their Big Mill Pro package. The system includes a Big Mill LSG with two Timberjigs, mounts from the Big Mill Basic, extended arms that hold the two guide rails on either side of the log, and two extra, sturdier fixing plates for the log ends. The aluminium guide rails can be fitted together and extended when required and are available in lengths of 0.5m, 1m, and 2.75m (1’ 8”, 3’ 3”, and 9’). 01361 840 251 www.logosol.co.uk Marshall Agricultural Engineering Serra have recently launched a new, competitively priced sawmill, the Alpina KE90, aimed at the smaller professional user or cooperative groups who require a fast and accurate cutting whether in small or large quantities. Available in static or mobile configuration it has a 4.8m cutting capacity which can be extended if required. The main frame is anodised with powder coated log supports. The shortest distance between the log supports is 25cm, allowing short logs from 0.6m in length to be cut. The Alpina comes with a lot of useful features as standard and additional equipment can be fitted at a later stage as required. The Montana is also available in mobile or static configuration, with two standard lengths, 7 or 9 metres, and a 90cm cutting capacity. Two power options are available – electric or with a Kubota diesel engine. The Bavaria SL range, models 110i and 130i, are high capacity machines. Angled sawheads, hydraulic tensioning of the saw, and the ability to use shorter saw bands all help to produce a fast and strong cutting action. A fully automated cutting system is available along with digitally programmable saw positions and joystick control. The Africa SL 130S and 160S sawmills are heavily built mills designed to handle and process large diameter hardwoods. The award winning SL 130 sawhead is now used on the Africa range. A full range of hydraulic accessories for the safe loading and handling of logs on the mill are available through to unloading and sending on for further processing. (Left) The Supermill from Mahoe uses ‘Cut to Taper’ to maximise full length board recovery by cutting the second grade core wood out in a tapered board. (Right) The Alaskan mill from Granberg fits around all makes and models of chainsaw quickly and easily. 40 www.forestryjournal.co.uk Forestry Journal 2/10 (Left) The Lucas Mill range from Fuelwood has just been extended to three models. (Right) The new Serra Alpina KE90 from Marshall Agricultural Engineering is aimed at the smaller professional user who requires a fast and accurate cutting ability. All mills are ergonomically designed for operator comfort and the cabins can be either a basic enclosure to keep the worst of the weather off or fully air conditioned. 01892 770788 www.marshalllogging.co.uk M Large Tree Services Ltd M Large have bucked the trend and started manufacturing in the UK. Their first project, the LMS 680 portable sawmill, is available with a 9hp or 13hp Honda engine, and can handle logs up to 680mm diameter (27”) by 4m (13’) long. Each mill is supplied with the new 32mm Ripper37 bandsaw blade, manufactured in the UK by DakinFlathers (see www.ripper37.com). The cutting depth is easily set (in 1mm increments) with a simple hand operated ratchet locking system. Blade lubrication is standard, using fluid metered from a removable container. Sawdust exits away from the operator through a duct to which a bag or collection box can be fitted. Most of the sawhead and track are galvanised or electroplated for corrosion resistance. The LMS 680 is delivered to the customer completely assembled, apart from joining the two eight foot sections of track. This should take no more than 20 minutes. A range of extras will be available including track extensions and blade sharpeners etc along with a chainsaw mounted debarker for cleaning logs prior to cutting. The big brother of the 680 will be launched this spring. This model, the LMS 860, will be available with a 13hp or 20hp electric start Honda petrol engine, and, using 38mm blades, will have a cutting capacity of 860mm diameter by 4m long (34” x 13’). 028 9034 2838 www.mlarge.com Mahoe Mahoe (pronounced Ma-ho-ee) Forestry Journal 2/10 sawmills operate using a twin circular blade system. The blades run at right angles to one another simultaneously cutting two faces of the timber with each pass. The powerfed head passes along a high tensile single triangular boom which allows easy loading and clearing. The Mahoe range of sawmills includes the Minimax, which can handle a 6.2m x 1.8m log, runs on a 35hp Daihatsu-made Briggs and Stratton petrol engine, and has a manually operated rise and fall system. The Supermill can handle a slightly wider log, has hydraulic rise and fall and runs with a 42hp Kubota diesel engine. Both cut a maximum 12” x 8” beam and return each timber to the operator as it is cut. There is no need for a resaw. What would normally be taken out as falling boards on a bandsaw mill can be sized and square edged for stock as they are removed from the edges of the sawlog. The mills have taper adjustment to maximise quality boards from the log and cut out any shake or poor quality core wood. Both mills can be supplied fully mobile with bogie-style trailers which run under the single boom, and accessories include a slabbing attachment, also power-fed, which can cut 1.5m wide slabs should one have particularly special trees. Saw doctoring costs are kept to a minimum with either inserted tooth blades or standard tungsten carbide tipped (TCT) blades. Sharpening is by a supplied jig system and is ‘foolproof’. Both the Minimax and Supermill models will hopefully be available direct in the UK by early spring – keep an eye out at the shows this year. 07849 975363 www.mobilesawmills.co.uk Saws UK Saws (UK) Ltd have been the agents for Forestor Sawmills in the UK for more than four years now. During this time, they say, there has been a lack of mobile sawmills in the range and they have also been limited to narrow band sawmills. From 2010, both of these issues have been resolved with the addition of the Pezzolato range of machines. The cheapest totally hydraulic short-blade sawmills in the range, the Timber Queen HD6, HD7 or HD8, can handle a maximum log diameter of 900 mm and cut up to 6.1 metres in length. They can be powered by a 2-cylinder petrol or 4-cylinder diesel engine. All functions of the head and handling of logs such as log grip, log turner and log leveller are hydraulic and included in the standard equipment. All the machines are equipped with a two-armed loader, and trailers for towing up to 50 mph can be provided. The Mini Profi range, including the 800, 900 and 1000 series, have a horizontal cutting head with a maximum log diameter of 1 metre and a cutting length of 6.1 metres. Powered by either an electric or diesel motor, they are equipped with a hydraulic flywheel, brake, blade tensioning and blade protection and two-chain head forwarding system. Accessories include a computer, debarking device, plank removing arm and hydraulic log loader. Both the Mini Profi 900 and 1000 models have been improved to satisfy the demands of professional users. Modifications have been made to the framework to make log handling much easier and increase production capacity. 01435 862229 www.sawsuk.com Wood-Mizer The LT10, smallest in the range from Wood-Mizer, is an electrically www.forestryjournal.co.uk driven, manually fed mill capable of sawing a log up to 70cm diameter. The slightly larger LT15 is of similar capacity but of stronger build, partially manual and partly automated. It has a powered up/down and hand crank feed system. It is available in diesel, petrol or electric versions and suits mobile operation. The LT15 can be palletised or towed with an optional trailer package. The small-to-medium LT20 series has the traditional style bedframe and the recognisable cantilevered sawing head. A ‘chunkier’ version, the LT20B, was developed during the 2009 credit crunch for sawyers who needed something stronger without the capital outlay of the LT40. The trailer package on the LT20 series includes adjustable outriggers which comply with trailer specifications. Both LT20 versions are equipped with SW Setworks as standard. The LT40 series can be used either as a mobile or a stationary mill and has been operated in all sorts of environments. The LT40 has a 90cm log diameter capacity and can be driven by a variety of power sources including diesel, petrol and electricity. It also has standard SW Setworks and is easily towed by virtually any vehicle. The semi-industrial LT70 series is heavier and stronger than the others. It has computerised Setworks plus other benefits, and again is easy to tow. Various accessories and options are available including ‘Accuset’ pre-programming systems, an ‘Auto Clutch’ system, bed extensions which can add 1.8, 3.6 or 7.2 metres to standard bed sections, ‘LubeMizer’, which helps melt away sap, and a debarker. 01622 813201 www.wood-mizer.eu 41
