The kerf on a chainsaw is at least 10mm to 12mm in compare to a Bandsawmill 3mm! Your claim bandsawmills wander a bit... only if your blade is dull or badly maintained! I cut on my Bandsawmill up to 4000pmp a day,average 2000pmp depends how the wood is! You can not possybly mach that nearly with a Chainsawcut! But than thats what you got and you may as well use it! My boards are cut 1'' on center, i plane them down to 3/4 and have therefore very little sawdust or shavings,my shavings are pressed to Briquettes so i have allmost no loss! Fritz
