There is no need to abuse the mill as its much easier on the gear and blade to effortlessly take wide cuts in sections. This is especially true in milling timbers such as Oak and Ironwood. These timbers may require up to 3 sectional cuts to cut a 12" wide board. Another advantage of sectional cuts is that the first cut provides a trace for the second or if necessary 3rd cut.
Meaning the accuracy of the board from one edge to the other is guided true. This is really the only way to saw up wide horizontal boards accurately. A twin-blade will struggle with wide cuts in hard timber. The Turbosawmill has the answer here too; as our swing-blades are automated! It takes away all the extra walking up and down the log to make these sectional cuts.
You may have noticed that the Swing-blades seem to achieve very good production results at competitions such as the Paul Bunyan Shootout where other mills compete head to head.
Dollar for dollar they seem to shine. One of the secrets is the fact that one blade is able to cut the next board while the off bearer is given time to collect the previously cut board. This shaves a good seconds off each board cut. You may have noticed attempts in where other twin-blades were entered into this competition; the fact that they had to cut the board and then return the head ready for the next cut limited their ability to compete.
The Turbosawmill takes this advantage to the next level. Our Automated mill lets one operator produce what other swing-blade mills would achieve with 2 operators. Our automated mills cut the next board automatically giving time to collect and stack each board before needing to actuate to the next board. Makes a very productive solution! One blade makes milling tensioned logs very easy. The ability to start vertical first and horizontal second or vice versa means you won't have to contend with stress of the cut timber rubbing up against your blade.
This is typical for twin blade designs. Just switch patterns if you start to experience stress. The Turbosawmill design means a one man operation simply steps around the carriage when sawing horizontal first. Other Manufacturers require the operator to wedge each beam or walk around the complete sawmill to collect the timber. That's the mono rail difference! We also offer taper board options through a simple add on gadget.
Our mills can also be fitted with our attachment slabber making slabbing up to 61" possible. So these two options really open up the sawyers possibilities! The band-saw mill has an uncanny ability to hide its kerf loss within your timber. In a lot of cases it goes unnoticed, leaving the sawyer feeling good about themselves, saving maybe every board for every bunch of boards produced with a circle mill.
The reality of it is a thin blade deflects, the wider you go the less blade support you get. So what ever savings you may end up becomes apparent when you are ready to plane the boards into a true workable end product. The indisputable advantage of a circle mill is that it reliably cuts straight even if your blade is blunt. Your feed rate slows letting you know that its time to sharpen the blade.
By the time you figure out the band-mill is dull you've started to saw waves damaging potentially 2 valuable slabs. The great thing about the swing blade is the cost of maintaining your blade. A swing blade is an extremely low cost method of sawing timber. That is usually where the stress starts becoming more of a problem and a correction cut or two might creep up.
Finally calling it a firewood slab when it starts playing out or gets too flimsy to support itself. It can be aligned to the blade end to end and used to quickly center and support small logs.
We'll use it after drying dimension stock to straightline it. On roller tables up to 40' long weve set logs on a long timber and cut till we run out of rail, roll in and continue cutting a long timber. Basically its a pretty versatile mill, we are always looking at different pieces of "furniture", jigs to make it more versatile for some custom cut or another.

Cut them vertical for the 1st third of the log, then switch to horizontal for the centre, and vertical again for the last part. You get some rift sawn on the corners, but the yield and sawing time are about the same either way. March 30, , PM by Magicman. February 23, , PM by Okrafarmer. Sawing technique, Slab turn 90 or ?

A rise and fall mechanism is mounted within a carriage which is pushed and pulled upon parallel tracks over a stationary log. All rights reserved. Privacy Policy. How our swingblade circular sawmills work. The Concept. The First Cut. The Return Cut. Step by step. The cutting begins at the top of the log with the blade in the horizontal position, where small waste pieces are removed to expose the first useable layer of the log. The horizontal cut is always done pushing forward, and the vertical cut is always done pulling backward.
Once you have reached your desired depth of cut, you can remove the waste edge from the left of the log by cutting forward horizontally to the far end of the log, and then pivoting the blade into the vertical position and pulling backwards.
