Types of log saws
However, there are two major families and they differ according to their power source.
Electric Log Saws
Designed for small-scale or irregular work, electric log saws are primarily intended for personal use. Easy to operate, relatively light weight and low noise, they are ideal for preparing wood for the winter, for cutting logs to the right length, or for breaking down logs for easier removal. Commonly equipped with a 40 cm (15.7") to 50 cm (19.6") diameter blade, the most powerful electric log saws can accommodate a blade of 60 cm (23.6") to 70 cm (27.5"). The power usage is between 2000 and 3000 W.
Thermal log saws
Geared more towards substantial or frequent work, thermal log saws are more advantageous for professionals. Just as easy to use, they are nevertheless heavier and obviously much noisier than electric log saws. On the other hand, thermal log saws are self-contained and can be used directly at the site or any other place without electricity. The majority of thermal models offer a blade of 60 cm (23.6") to 70 cm (27.5"). On the power side, a 45 cm3 (2.74") to 60 cm3 (3.66") motor (which corresponds to about 2.5 kW of output) is the minimum requirement. For large scale, continuous use, some saws are equipped with a motor of up to 125 cm3 (about 7 kW).
Characteristics of a log saw
- Blade Diameter of 40 cm (15.7") = Maximum cutting capacity of 17 cm (6.6")
- Blade Diameter of 50 cm (19.6") = Maximum cutting capacity of 19 cm (7.4")
- Blade Diameter of 60 cm (23.6") = Maximum cutting capacity of 23 cm (9.0")
- Blade Diameter of 70 cm (27.5") = Maximum cutting capacity of 27 cm (10.6")
In general, the power of the motor, whether electric or thermal, determines to the maximum diameter of the blade that the saw. Whatever your cutting capacity needs, you will need a motor of at least 2000 W - about 50 cm3 (3.0") for a thermal engine. If you have particularly large pieces or a particularly large volume to cut, favour a high-power motor - greater than 3000 W / 75 cm 3 (4.5").
As you can imagine, a large blade with sharp teeth being launched at high speeds is dangerous. Be sure to select a log saw with both a safety guard and an easily accessible circuit breaker.
Final tip for choosing a log saw

Electrician by trade, I first worked in industrial estates where I installed, wired and fixed a large number of electrical installations. After this, I managed a team of electricians for this type of work. 10 years or so ago, I turned to building and construction. From the modest family home, to gyms and theatres; I have been able to coordinate, audit and organise all sorts of construction sites.
for 4 years now, I am restaoring and bulding an extrension to a bungalow in the heart of the welsh countyside. My experience in manual work and my knowledge means I am proud to be of service. Terraces, interior design, roofing, plumbing, electricty, anything goes! We have, my wife, daughter and I, built almost everything we have from scratch! So to answer all of your questions, and to orientate and advise you on coosing your tools? Easy!
