Just got a block plane from Lowes (the only one on the display). It has a cup on its sole. Is it supposed to be like that?

Take it back. The bottom of the plane should be totally flat within the reasonable ability to measure flatness.

  • Fully agree that it should be flat. It could be lapped but since you just purchased it take it back.+ – Ed Beal Jul 2 '18 at 13:24
  • @EdBeal - If he had access to a surface grinder that plane could be fixed. Hand lapping it would take forever. Another thing is that seeing that the plane had such a dip in its base makes one wonder if the rest of the plane had good surfaces. For all we know the blade could even rock when placed into position. – Michael Karas Jul 2 '18 at 13:53

Most hand planes you buy unless you get a premium hand plane you need to tune. There are several tutorials online on how to do that. http://www.instructables.com/id/Tuning-a-Hand-Plane/

I normally take plane apart and flatten the sole using a granite stone using higher number wet sandpaper, the water will keep the paper sticking to stone.

You can use a permanent marker on sole and when lines disappear your sole is flat.

You should also flatten the back of your blade using same technique.

To get proper bevel I prefer this tool.

I hope this will explain it in more detail.

Now this takes time but the rewards comes when your tool works as it should and you get crisp cuts each time.

  • i think it is a valid answer, the rules need to be made more linear – Trident D'Gao Jul 2 '18 at 19:39
  • @1224 not sure which version of answer you saw first but when I wrote my comment the answer was literally 2 sentences with no links, definitions of terms, etc. It's been heavily rewritten since then. – The Evil Greebo Jul 2 '18 at 19:43
