so to start off here you're going to want to check your infeed and outfeed table and make sure they are coplanar and flat do this by raising your infeed table all the way up and checking it against the outfeed table for coplanar just use a straightedge for this and check both parallel to the tables and diagonal and just see if you see any light underneath the straightedge I didn't see any on mine so I was good to go this is also a good time to check your fence for square and make any adjustments there next I decided to change the knives in my jointer this is pretty easy but can take some time start by loosening all of the jack screws that are in there to release the knives and then just put the new knives in when you're tightening the jack screws only tighten two of them and tighten them just enough to hold the blade in place because we need to adjust the height of the blade to start adjusting the height of the knives set your dial indicator to zero based on the height of your outfeed table then that zero is the height that you want to set your knives to you need to do this in the front of the knives the middle and the back to ensure that they are parallel with the outfeed table this can take some time and it can be very finicky you'd be much better off just making a jig to do this as opposed to doing it with the dial indicator and so once the knives are set in place just go ahead and tighten up all the other jack screws but once you're done make sure you check the knives again because they could have moved next we'll double check the height of our knives using our straightedge and you're going to want to do this again in the front and the back of the jointer just go ahead and strut your sage straight edge over the cutter head and measure how far the knives move the straight edge if they move them the same distance then you're good to go and with that done we can go ahead and adjust the distance that the infeed and outfeed table are from the knives if you want the infeed and outfeed table as close to the knives as possible without touching them of course and this is what helps to reduce break out when you're jointing your lumber and with all of our setup work done we can give it a shot so we'll go ahead and flatten one face of the board and straighten one edge and check for 90 degrees and there we have it it took a little while but we got there
