Cheat Sheet
« on: April 23, 2019, 01:35:40 PM »
First let me throw in a disclaimer - im sure this is not an original idea by any means and could probably be added on and improved on tremendously but it helped me so I figured I would share..

Most of my framing lumber I cut for my projects I run 2x4s at 1-1/2" x 3-1/2", 2x6s at 1-1/2" x 5-1/2" etc. so im cutting actual dimensions off the mill instead of nominal with the exceptions of 1x - I cut them a full inch. In my air drying im only losing about 1/16" each direction and im good with that. Plus the weight difference in full size with green lumber is very noticeable after you move a few hundred boards in a day..

Since im running repeated numbers and I found the math I kept doing in my head was getting redundant I wrote a sheet up accounting for the 1/8" kerf each time on each board and printed it on a sheet and stuck it to the lid on my controls. This list covers me for all 1x4,6,8,10 & 2x4,6,8,10. When im slabbing on my 3rd side around (for my widths) I can look at the 5-1/2" table (if im running 1x or 2x6s) and know that if I cut at 16 - 3/4" I will come out perfect with no waste on the bottom side for 3 equal widths - then when I roll to my 4th side I can cut at say 14-1/2" for example and get 9 boards from each width with a perfect 1-1/2" board on the bottom. It lets you throw your waste on top with the slab instead of having an oddball board on the bottom of the stack.

I guess you could apply this to any size you cut repeatedly but sure speed my math up and cut down on my waste. I used to just let that last board be a screwball but this is definetly a better way.

I would be interested to see all the cheat sheets yall have come up with because I know there are a lot out there that would be helpful on redundant measurements.

  Here is mine. I keep it in a ziplock bag under the cover of my Simple Set so it stays waterproof. I swear by it.

Mine is laminated and has full dimension on one side and nominal on the other. Thereís also a free app called sawmill calculator that you can set up your own cut list. Unfortunately though it isnít working right now. Apparently apple made some changes and the app isnít compatible with iPhones.

 Just in the way of FYI if you cut 1 1/2" it will shrink below building standard so I always recommend 1 3/4 X 3 1/2or %5 1/2  otherwise it cant be graded as 2 & btr  stuctural , still ok for strapping or sheathing but not framing on anything you need a permit for in Canada anyway but I'm pretty sure alot of states are the same if you need to have your lumber graded the make sure you need to have your lumber graded then cut it oversize to alow for shrinkage most don't care if it's an 1/8 under in width but 1/8 under in thickness is to much leaving absolutely no allowance for saw deviation.
