I have great difficulty get the plane blade set square after sharpening. I spend ages fiddling taking shavings on scrap pine trying to get it right but once I think it’s right and move to the actual job it planes out of square and I’m back to fidding for an hour trying to get it right. Any suggestions ?
First make sure the sharpened edge of your blade is square to the side of the blade. Use your tri-square to determine this. When I sharpen I tend to take more off the right side of the edge and need to adjust my “focus” on the left edge when sharpening. Sometimes things get so out of whack that there is not enough lateral adjustment to overcome this unintentional skewing. I then need to go the the grinder and start over.
Once square and sharp, carefully set the blade in the plane as square as possible. Make sure the hole in the blade engages the lateral adjuster. Then move the blade in or out so any chip is very thin.
Use a 3/4″ wide pine board to test each side of the blade by running the plane along the edge. Use very small adjustments and move the lateral adjuster in the direction of the fatter chip.

First off I usually check my plane irons for out of squareness before I start to sharpen. That way I know where to add a bit more pressure. Slowly they get more square that way. Good to use for chisel too.
A little bit out of square shouldn’t need to be a problem though, as long as you have a straight edge.
If I understand correctly it might seem that the iron isn’t cinched down on the frog tight enough, allowing it to move as you plane, thus throwing off your corrections.
And adding on to what Alien8 said, if the iron is not cinched down to the frog well enough, tighten the lever cap a bit. That could help keep it from moving while you plane. The lever cap screw should be tight enough so that when the lever cap is replaced, it gives a good “click” when pushing the cam mechanism down to lock it. There should be fair resistance, but definitely should not be very hard to lock the mechanism.
