Topic tags/keywords: plane sharpening question

Hi All:
I have just acquired a Millers Falls No 77 Router plane and have some questions I need help with. The plane is in excellent shape, the sole has a few scratches and a little surface rust. The bits have several small pits on the bottom and on the bevel. Should I flatten the sole and remove the scratches? Should I also remove the pits on the bottom of the bits? I don’t want to just start doing things and end up ruining the tool. Any help will be appreciated. Thanks

The pits and scratches on the sole won’t affect anything, but you’ll want to get the rust off so it doesn’t get worse and it can get onto the piece you’re working on. The pits on the bits will affect how sharp you can get them if they are right up at the cutting edge either on the bottom or on the bevel. If not they don’t matter much. I haven’t seen a 77 but I assume the bottom of the bits has a relief angle where only the cutting edge is touching the workpiece doing use. The rest of the bottom doesn’t affect the sharpness.

If you want to post a photo here how nicely you removed scratches go ahead and do it. Otherwise if you plan to actualy use the plane why bother? You will get new scratches with use anyway. Same for the blades. If the pits are close to the cutting edge you’d better regrind the bevel. If not just let them be, eventually you will get rid of them as you keep honing the blade.

Thanks Tim.
The bottom of the bits do have a relief angle. When I get the bits cleaned up and all pits removed what surface do I sharpen? The bottom or the bevels on the bits?
Thanks
