When feeding a board say about 8 ' wide into the planer it comes out the other end crooked at about 20 degrees.what can be causing this.The model is Delta TP 305 , 12 1/2".
There are a possible number of causes, few of which can be adjusted away.
However, check to make sure the base of the planer, the table under the board is clean and free of pitch and scratches or debris that could interfere with the smooth passage of the board. I use Trewax or some other paste wax on mine to facilitate the board's passage.
You may have a feed roller that is tighter on one side than another, i.e. it is closer to the table on one end than the other end of the roller. It's unlikely there's anything you can do about this, even if you were to make the appropriate hardwood block needed to measure the roller's height at different positions across the table. Small portable planers are prone to this, and often your only recourse is to hold the board straight as it feeds through the machine, by exerting gradual pressure on the side against which it twists.
Finally,it could be the boards that you're feeding into the machine are not flat or have non-parrallel faces to begin with, so the knives of the planer are forced to take a deeper cut off one side of the board. Take a lighter pass and see if the board runs straight. You might be hogging too much off for the planer.
Or the knives could be dull, or knicked, or improperly adjusted and not parrallel to the cutterhead.
But this can be a problem even with industrial quality machines. Normally we just hold the board straight and move on the the jointer or the table saw. It's frustrating behavior, but you can only spend so much time tweaking machines, and then you have to get on with the woodworking.
Hope that helps somehow.
