I’d be curious to know if anyone has made a scraping plane and what you used for the blade. I have a few very thick (1/4 inch) blades for wooden planes. I am not sure about specifically what kind of steel, but it is definitely a high-carbon steel and judging by the way it sharpens I think it would be too hard/brittle to turn a hook like one would on a card scraper. Would it be suitable to make a scraping plane with a blade with no hook? I see Lie-Nielsen does not advise turning a hook on theirs, but other manufacturers do.

I currently have a Veritas large scraping plane and have always turned a hook on it, but it’s not very useful for me because it is too big and I find that the surface is at all slightly out of flat (really not a sin on the outsides of a cabinet in my opinion) then the plane chatters or does not make enough contact to get a good cut. I think what I really want is the smaller Lie-Nielsen scraping plane but I am trying to economize my woodworking costs and avoid pricey tool purchases.

You could buy the Lee Valley or Lie Nielsen replacement blades if you wanted to. Otherwise saw blades make a good scraper. Depends on the level you’re going for I guess. Not sure about the hardness of the inside of circular saw blades, but that might be an option for steel thicker than a handsaw blade. Of course you can always buy tool steel from McMaster Carr and similar.

Are the thicker planes for the Lie-Nieslen and similar scraping planes a softer steel than a standard plane iron?

I am asking about the blades I have because they are really nice blades but I am having trouble finding a project for them.

I’ve made scrapers with both vintage plane irons and scraper blades. The thinner blades work better with a hook. As the blade gets thicker, the hook seems less important.

Do you feel one is better than another? What are the differences between the thick and thin blades in your experience?

For fine scraping on really difficult grain I like the hook especially in the larger scrapers. The smaller scrapers I made with block plane blades works well. I think the blades without a hook push harder. If I could only have one I’d want the hook. What I like about the non hook is they are quicker and easier to sharpen. I have a place for both in my shop.

You can hook the thicker irons if they are tampered correctly.

Here are a couple of scraper planes I made for a bar rail moulding. The blades are pieces of an old cheap hand saw, shaped and with a hook pulled over. They worked very well to smooth out the project.

Not to get too far away from wooden planes, but, have you tried a Stanley No.80?

I have one of these with a Hock iron, ground to 45* with a hook. The nice thing about the 80 is you just set the iron flush to the bottom, then use the thumb screw to adjust the ‘depth of cut’.

Mark,

The scraper planes in my post are inspired by my Stanley #80.
