I have the same issue, my 18" is not anybody else's 18", when friends & family help cut I get a very mixed length. I can fit 24" in the BK but prefer 18" +/- 1". I've been called anal by buddies when helping build my shop (36 X 52) but, I cut every stud exact. It went together square. That said, I'm only asking for 18" +/- 1" or so. It stacks better & always fits into the stove the same. The stick helps but is slow. I may come up with an attached 18 wire on the bar nuts. Anal, yeh, but I've witnessed worse people problems & behaviors going the other direction. Now that I'm retired & can do it my way, I do it my way best I can. I know if I was selling wood 18" +/- 1" it would be that. After a few weeks of steady cutting I'd probably get good enough to be in specs, but other projects keep getting in the way. So I'll put a mark on the bar, have my stick handy & when cutting a bunch of logs, like now I'll hook a wire or something to the bar nuts like jebatty "If I have a lot of logs to cut, then I use a marker fixed to one of the bar nuts. Nothing more than a piece of #9 steel wire with a loop the diameter of the bar bolt to fix it under the bar nuts" Good one Jim Thanks, I learned allot Good bunch of folks here, lots of knowledge too.
