Woodlandia log lathe LL-41 is "four in one tool" for production of cylindrically shaped logs used in log home manufacturing. These milled logs (a.k.a giant dowels) are main component of log home or log cabin shell. The lathe is able to perform four essential operations on the log: turning, C-groove (Swedish cope), notching, kerfing.

The LL-41 log turning mill can accommodate up to 19½ inches (500mm) row logs. In standard configuration this log rounding machine produces cylindrical log with diameter from 6 to 18 inches (150 - 460 mm).

Also the lathe can mill round notch and Swedish cope for diameters from 6¼  to 12½ inches (160 - 320 mm).

Lathe output depends on skills of the operator and the production process. In average 10, 1 foot (300mm) in diameter, 20 feet (6m) length logs can be manufactured per work shift by 1 operator and 1 helper. An average of 3-5 days would be required to process logs for a basic 16x16 feet log cabin shell.

The machine is delivered as a LOG LATHE KIT. Assembling is required at owner's site (assembling manual is provided). 

LL-41 in conjunction with RoundMaster are intended for small or medium size businesses where automation is not required. Such business can produce log works for about 15-20 $/sq foot (160-200 $/m²) or less if manufacturing is well organized. Labor cost is 50-70% of total cost therefore in areas or countries where labor is cheaper than $30/h, final price will be proportionally less than $15/sq foot...

Construction 

The LL-41 consists of a modular frame, head stock, tail stocks and moving carriage. The L-41 is intended for heavy duty work.

Tail stock is movable along the frame to accommodate a length of input log. The stock has a pike where the log top is fixed to. Tail stock pike is motorized allowing extension of pike up to 1 ft (30cm)

Head stock has another pike which is fixed to the frame. This pike (axle) is driven (via gear box) by an electric motor that provides turnng of a log. Moving carriage of LL-41 travels forward and back along the base frame driven by electrical motor and chain gear. Moving carriage has 2 mills: vertical and horizontal. Horizontal mill is intended for:

• debarking
• removing of thick layer of wood
• milling of lateral groove (Swedish Cope)

Vertical mill is intended for:

• finishing of a log surface
• milling of round notches
• flattaning  (planing) the surface

The log lathe is controlled manually by operator via buttons on control panel.

Setup & Power requirements

Optionally, Woodlandia can ship “ready to work” log lathe in conjunction with diesel generator and fuel tank on 50 feet flat trailer with attached hydraulic legs. Such combination allows making mobile log lathe which can be relocated between building yards as necessary. Just move, unpack, level the trailer using attached legs and the lathe is ready to build log home wherever the trailer can be towed to. More information will come soon…

• LL-41K with all motors powered by 3 phases, 480V, 60Hz electricity
• LL-41KE with motors for 3 phases, 380V, 50Hz 

Optionally the lathe can be supplied with proper diesel generator to satisfy customers in remote areas or where 3 phase electricity is not available.

Minimum 25KW generator is required to power LL-41. However we suggest to look at 30KW-40KW generator because bigger generator can consume less diesel fuel to generate enough power for LL-41 (this statement should be evaluated by yourself by looking into particular generator's fuel consumption data). For example 35KW generator we have in our demo place consumes:

L / hr	KW
8.6	37.4
6.8	26.18
4.9	18.7
3.9	14.96

You can look for used or new generator at:

• local manufacturer

• local liquidation auction
• www.ebay.com

Woodlandia can recommend two Ontario (Canada) based generator manufacturers, please contact us for details..

Specification

Technical specification for log lathe LL-41

Physical characteristics

Height:  7 feet ( 2.1 m)
Weight: 4080 pounds (1850 kg)

Environment: from -10 to +40 degrees Celsius.

 

Power requirements

• LL-41K: 3 phases, 470V, 60Hz

Specification can be changed without notification to  improve capabilities

• LL-41KE: 30A, 3 phases, 380V, 50Hz

 

Row material and product

 

• Min log length:  18 inches (380mm)
• Max log length: 26½ feet (8100 mm)
• Output dowel (cylindrical log): 6-18" (150 - 460 mm)

 

Logs for log constructions (logs with Swedich Cope): 

in/max	diameter, inches	diameter, mm	note
Min input log diameter:	7	180	recommended minimum input diameter of trunk top
Max input log diameter:	19	500	recommended maximum input diameter of trunk butt; no more than specified number including remainings of branches
Min output log diameter:	6	150	it is possible to turn log with less diameter however extra care during the work should be taken
Max output log diameter:	12½	320	it is possible to make just cylindrical logs with diameter up to 18 inches (460mm)

Productivity

Output depends on skills of operator, quality of raw materials, infrastructure and how well the production process is organized.
Required personal: for optimal productivity 1 operator and 1 assistant are recommended.
Average output is 150-300 linear feet of logs per 8h work shift.

The efficiency can be increased by using RoundMaster optimization complex.
