I just got a used Stanley Bailey #4 plane and I'm trying to sharpen it. The bevel angle looks to be more acute than 25 deg. I honed it and it's nice and sharp, but is only taking dust and thin slivers. Doesn't feel like it's cutting right. Feels like it's scraping more than slicing.

What is the proper bevel angle for this? Another dumb question: the bevel goes DOWN, right?

Thanks in advance - shawn
