Is it possible to make two passes on a log that is wider than your bar length? e.g. using a 32" bar on a 60" wide log and making cuts on both sides. Thanks A.It is possible. The longer the overlap of the cuts the better; e.g., a 36" bar would be better than a 32" in the above example. It is important to note that with the small mill the blade does tend to follow the tensions in the wood and create more variance than in the standard Alaskan mill.
Q.I had this on my Craftsman with a 20 " bar and now want to use it on my Echo with a 24" bar. Is there a problem with doing this other than the bar going past the end of the guard. A.It can be use with any size bar. As you say with longer bars the tip will be past the guard. As you cut larger wood it increases the amount the bar will move vertically (dip or rise) because of the tensions in the wood. Accuracy of cut can decrease in the larger wood, which is logical if you consider that the end of the bar is not supported as it is with the standard Alaskan mill.
Sounds like you're in the same boat as me. I've been considering my options, so when I saw yours and Old Timers post about the Small Log Mill, I looked it up. Not an extensive search, but I found the above answers to a couple of questions. I've highlighted the main points. Looks like there is some flex; maybe it would be better used to make thick slabs or cants which you could transport to a mill later.
