no previous part Part 1 of preparing wood series no next part

here is the process called ’ milling ’ .
i was asked to explain this in a PM , and did so ,
but the written explanation was to confusing ,
so i did this and took pictures and wrote this explanation .
it was so well recieved , i was asked to share it with others ,
that may have questions too , but might feel ’ dumb ’ asking ,
( there are no dumb questions ) , especially here on LJ’s
so here goes .
milling is taking rough or twisted/warped lumber and making straight and parallel stock out of it .
in using rough stock , it maybe called say 4/4 , but that is rough , finished it will be 13/16 or 3/4 ( in inches ) ,and it is still called 4/4 ( thats where it came from ) .
if it is 8/4 ( 2 inches ) it might mill to 1 3/4 inches .and still be considered 8/4 .
i used a particularly warped , cupped and twisted board for this demo , and even curved the edge , so you could understand the process .
.
this is the board , notice the cupping .

.
this is a JOINTER , its job is to flatten and straighten .
the knives are on the bottom ,and cut INTO the work ,

.
this is siting down on the JOINTER with the ’ crown ’ up , so it has a firmer base , and doesn’t rock around .
notice it is raised up in front , as i use the push handle to firm it to the table , this is good , it will go thru without
bouncing around , and after 3 passes , will leave me a flat , straight ’ face ’ .


.
this is one pass ,notice it cut only the edges , the middle is still cupped , but now it sits firmer on the table

.
this is the flat face . it is turned to you to show you the finished face ,
it will be turned around for the next step .

. straight and flat too .now i will put the flat face to the fence , and holding it to the fence , it will joint the edge 90 deg. , and make it straight too .this is 1 pass so you can see the curve and the new flat edge .

.
now the completed face with a square edge , this i refer to as my ’ reference ’ for all future work ,
it is my true flat 90 deg corner . here i rip the other edge on the table saw ,
the ‘reference ’ face ’ is down and the true edge is against the fence

.
now the board has 1 flat ’ face ’ and 2 square edges , that are parallel .
this is the PLANER , it makes flat and parallel to the flat ’ face ’ and things thiner .
it also cuts into the work .
the wood goes ’ face ’ down , as the cutters are overhead on this one .
in all of these processes , we do it in stages , as whacking to much at a time can ruin the wood and the tools ,
and possibly YOU !

.
notice the 1st pass takes of the thick side , so 3 or more passes will bring it to flat and true throughout .


.
here is the finished board , it has 2 faces that are flat and parallel , and 2 edges that are straight and parallel ,
and 4- 90 deg, square corners .
i always make my stock a little longer , and after the milling process , as this is where ’ snipe ’ can be removed .
snipe is when either tool can ’ jump ’ the ends , and leave a divot .


so there you have it , for ’ milling ’ , it takes a jointer , a planer , and a table saw ( or band saw ) ,
they are the ’ trinity ’ to get stock that can be used with confidence to build whatever you like .
just assuming that your wood is straight and true , can lead to costly mistakes and frustration ,
and it lets you buy cheaper wood , as the mill doesn’t have to do it .
enjoy !

Great tutorial! I would also mention the direction of the grain (especially when going through the planer) to reduce tearout, and also putting some diagonal lines on the timber with soft pencil or crayon to see when its really flat.

Had I seen this tutorial first, I could have skipped 4 or 5 books and countless hours searching on the internet to “get” milling wood. You are a gifted teacher.

Should be required viewing for all those just starting out- and some of us old guys that forget the basics.

Thanks, David!

i sure hope so mario ,

we all take what we know for granted sometimes ,

and talk technical stuff that beginners don’t understand sometimes ,
and are intimidated to ask .

why go out and buy a planer ,
if you don’t know what it does ?

moshel ,
right you are ,
with lines , this would have been even more self explanatory .
never crossed my mind , until i saw your comment .

As someone that has started with too many warped and twisted boards.(pallets) Your pics and explanation was wonderful. Thank you for sharing your wisdom.
