Dan bought the mini-mill attachment for his chain saw back when we were working on the kitchen. He wanted to make his own posts and beam for a load bearing wall so we got it.
One thing we didn't do at the time, however, was to get the proper chain for it. Some folks say the regular across-the-grain cross-cut chain can simply be filed at a different angle to rip boards with the grain. That proved not to be as easy as promised. This time he bought a proper ripping chain for the job. The difference is in the angle of the cutting teeth. A regular chain is filed at a 35-degree angle, a ripping chain is filed to 10 degrees. This makes a huge difference in the ease of cutting, not to mention wear-and-tear on the saw.
|Wedges in the cut keep the saw from binding.|
One problem is that Dan only has a 20-inch saw, while the logs are wider than 20 inches. That has meant two cuts per side, flipping the log to get both cuts.
The guide that came with the mini-mill isn't long enough for our logs, so Dan has to stop and move the pieces to finish the cut.
|First two done.|
He says the ripping chain makes all the difference in the world, but also that it would be easier to do these on the sawmill like the posts. If only it were longer. Hmmmm...
