I'm questioning the way my sawyer is charging.
Through the years he's cut thousands of bdft for me of my personal logs I've brought to him and always charged me an hourly or bdft rate. He had red oak tree go down on his land and I offered to buy the lumber that came out of the three logs it made. All was quarter sawn 5/4. It had shake in a good bit of it and he adjusted for dimensions as it came out of the log. I agreed with most of his numbers although some where in his favor. I was present during all the sawing and pulled it off the mill as it was sawn. Backing up a bit I calculated bdft in the three logs using the Doyle scale which came to about 550 bdft before allocating for the shake. He guessed roughly 500 bdft also. The agreed on price was 4.50 bdft for green quarter sawn red oak. Today we finished sawing the third log. When calculating bdft for final tally he said that anything over 1" thick is treated as 2". So he essentially doubled the thickness from 5/4 to 8/4 and wanted to charge me as all the lumber being 8/4 thick rather than 5/4 thick. So his doubled calculations came out to 790 bdft =$3500.00 My question is why is he treating 5/4 as 8/4. Is this right? How do ya'll do it?
