My Stanley No35 planer had a blade that someone tried to sharpen once but didn’t do a very good job. It looks like they put it on a regular grindstone and couldn’t keep the angle right.
I milled a block of walnut to a 25 degree angle and screwed the blade down on it and took it to my belt sander with some well used 220 grit and sanded the surface on the blade down smooth and square. Then I took the block with the blade still on it to my table saw for a flat surface and ran it over some 220 and then some 500 grit sandpaper until the blade was shiny and sharp.
I tested it and it cuts see-through curls in walnut that use the entire blade width now.
It’s still a bit iffy on the walnut slab, but there are some cross grains in this chunk that are pretty dense. I’m slowly planing out all the imperfections though. You have to cut those cross grains very slowly, just a thickness of a cigarette paper or it’ll chatter. Next I’m going to get the sled (wood) to be completely level.
The best way I’ve heard to do this, (for wood sleds), with out having power tools for the job, is to color the bottom of the sled with black magic marker and take it to the ts and use a piece of 220 sand paper and then run the newly marked sled on the paper about 9 or 10 times then look at the bottom. This will show you the high and low points of the sled. Once all the marks disappear, It’s level with the surface your sanding on. I like to make sure by coloring the bottom once more and running on the sand paper 9 or 10 times again to make sure it’s completely level. Then wax the bottom, and try it out.
