I have a Ryobi AP1300 portable planer. I tried to remove the blades to replace them and two of the six hex screws that hold the blade on won't budge. The area where they are can only be accessed with an L shaped hex wrench and I think I have rounded the hole that the hex wrench fits because the wrench keeps slipping out. Does anyone have an idea to get the screws out short of sending it in ??

When this happened to me on my Ridgid planer I soaked the screws with WD40 and then tapped them out using a chisel, you'll need to get some new screws. I got mine at the hardware store( get a few extra). Good luck!

Thanks Dennis. I'll try the wd40 and chisel.

Note that i used the chisel to unscrew the screws by tapping them NOT to cut off the heads, just wanted to make sure you understood what I did.

I had to unscrew the screws with a chisel on my 12.5 inch delta too. They were so tight that they sparked when they broke loose, didn't have to buy new screws though.

I'd try this over WD40, it's a much better penetrating oil.

Kroil is the best penetrating oil I have used. 615-833-4101.

Had 4 frozen on the other blade. 6 total-so far I have removed 5. #6 is being a stinker but I'll get it. Thanks for the recommendation.
