Board's jointed edge uneven
It has been a while since I have been on here let alone a while since I had my Shopsmith running but I cannot figure out why I am getting an uneven jointed edge. I have checked the jointer faces and blades and all are true and even yet when I make a pass across the jointer, I end up with low spots and high spots. Looking for any insight as to what I am be doing wrong.

Re: Board's jointed edge uneven
How much material are you trying to take off at a time? I have found the less material the smoother the edge. Also, in what plane are you have a problem with. Are you getting highs and lows in the edge, or an edge not 90 degrees to the perpendicular.

When you say "low spots and high spots", are you referring to a ripple effect?greasemonkey2275 wrote:It has been a while since I have been on here let alone a while since I had my Shopsmith running but I cannot figure out why I am getting an uneven jointed edge.

Re: Board's jointed edge uneven
I am removing about 3/32" per pass and tried 1/16" and still had the same problem. I am trying to establish a flat edge on several pieces of resawn walnut; each piece is no more than 28" long.rjent wrote:How much material are you trying to take off at a time?

Re: Board's jointed edge uneven
Not the ripple effect; the ends of the board are low and the center is high over a 28" pass.Dansmith wrote:When you say "low spots and high spots", are you referring to a ripple effect?

Re: Board's jointed edge uneven
Try cranking it down (up) to a 1/64 th or so and see what happens. How are you feeding the stock (pad, push sticks, ??), and are you using the featherboard.

Re: Board's jointed edge uneven
If the blades in the cutter head do not all rise above the table surface by the same amount you will get a ripple effect as each blade cuts to its own depth.
Make certain that the blades are properly adjusted (same depth of cut).
Just curious, what method do you use to adjust the blades?

Re: Board's jointed edge uneven
You are not keeping the just planed edge tight to the OUT feed table.(assumes the blade height coincides with the outfeed table height). Once there is sufficient 'new' surface to assure alignment to the outfeed table, NO downward pressure should be exerted towards the infeed table.
Also the tables need to be 'coplaner'. Raise the infeed table until it is the same height as the outfeed table. A straight edge should touch all points on both tables regardless of it's position. The blades should 'just touch' that straight edge at their highest point.
When a workpiece is initially held tight to the IN feed table, the freshly cut end of the workpiece should just barely clear the leading edge of the OUT feed table and not rise above the OUT feed table as the workpiece moves forward. Once downward pressure is being applied to the OUT feed end, the trailing edge may properly ride above the IN feed table. If the workpiece is then forced down tight to the IN feed table the rocking chair rocker bottom effect will take place.
