We run a 12 mmfbm softwood (90% plus black spruce) sawmill in Newfoundland Canada. We produce dimensional lumber (3", 4" and 6" material from 8' and 12' logs) for the construction industry but our strategic focus is on products such as sidings, claddings, panellings, etc. manufactured from the 12' long, 6" cants. We are in stands with very slow growing softwoods (typical cycle is 90 plus years).
Our logs are typically very small with only 10-20% measuring over 7" in diameter. These larger logs are the ones we need for our value added products. However, occasionally we run into a stand with much larger logs which we cannot run through our regular production equipment. These would measure 17" - 24" in diameter and would be 12' long (for sidings and claddings). We want to purchase a saw (mobile would be nice but not absolutely necessary) that can efficiently breakdown a log that size into 6" cants. These cants can then be introduced to our regular process at our gangsaw. I know most of you guys are processing high value hardwoods, but are any of you doing size of logs that I have described here? If so, what are you using and what kind of production can you get?

From contributor B:
I hire out my custom sawing, but my sawyer is using a hydraulic Wood-Mizer. I think it's the LTH40 on a portable trailer that easily handles that size log. He's cut 3000' in a day with me and another worker handling the logs, and that wasn't a long day.
Another market is very wide boards. I have sold just about every pine board over 18 inches wide I could ever saw. If you can get the logs to the mill and the cants away two men could produce 1,000 bdft an hour cutting cants with no problem. When looking at a brand of mill look to see what can be serviced in your area and their warranty. Wood-Mizer, Baker, and Timber King all would be good choices, but having put 16,000 hours on a Wood-Mizer makes me lean towards them.
