Topic tags/keywords: hand plane refurbish fix flatten

I’m practicing refurbishing a cheaper Stanley Hand Plane, in hopes of gaining some experience before finding a good one to refurbish. I got a 3/8” thick piece of glass and am flattening the bottom of the plane.

I started with 120 then 220, and then finished with a few passes of 500.

You can see there’s a dip in the center of the sole, and its also not completely flat around the mouth. (thats a shadow at the heel end of the sole) Is this good enough? Or do I need to continue flattening? Thanks!

Imo, youre good. Front of the mouth and the heel seem to be even and thats about all that matters.

It’s completely flat except for that little dip in the center, and its not completely flat directly around the mouth

If the toe, heel and front of the mouth are co-planar, you are good, so depends on where your “not completely flat around the mouth” is at and how bad. A bit of a hollow where that is at is never going to be a problem.

My first few planes, I flattened and spent way too much time trying to get just perfect. Now, I sharpen it up, do a basic tuning, then use it and see what happens. If it works well, I don’t even bother checking how flat. If it doesn’t perform to my standard, then it’s time to see what else needs done. So regardless of what else is said, the big question is – How does it perform?

I’ll let you know how it performs shortly! Going to finish sharpening the blade real quick and give it a test drive! I’ll get back to you in 10 minutes :)

My prediction is that plane will pull a fine shaving.

Being the first time I’ve ever used a flat/sharp plane, I’d say this is pretty damn good. Of course I have nothing to compare it to. Excited to try a really good plane/blade

I’m not a plane guy, but, I’d say you’re doing a fantastic job. That ribbon is proof, that baby is sharp. Carry on.

Results look excellent!

You know you are “perfect” when you can take cuts that produce shavings with only one side.

Good job Doc.

A little Gulf wax on the sole and you’ll be making curlies all day:

As a side note, I always square at least one side of the body (right or left handed?) while flatten my planes in case you want to use it for shooting of your bench or on a board. I use self adhesive sand paper from auto body supplier I the 180 to 220 grit range stuck to a cast jointer or table saw top.

Nice progress, Dak. When the time comes that you’re able to hit finished work with your smoother, hear the sound and feel the soft surface left behind, planes will be part of your shop arsenal for the long haul.
