I received a few new items for the workshop for Christmas, namely an IBC blade for my #5, an 8000 grit waterstone, and a extra course / course DMT diamond stone.
So I got to work with lapping and sharpening the new plane blade on the extra course stone, and was sorely disappointed with the ‘courseness’ of this stone (also with the flatness of the blade out of the package). After nearly two hours on the stone I still have a decent hollow on the back of blade. So I figured maybe the blade is just very out of flat and I took a break from it and tried out another (original Stanley) blade as well as some chisels. Same thing, tons and tons of work and time and not making a lot of progress.
It became clear to me that none of my tools (which were flattened and sharpened using scary sharp) are as flat as I thought they were. So I feel that I am in need of a rougher grit to get my tools flattened and then reset the primary bevels. I’ve been looking at the extra-extra course DMT as this is around 120 grit equivalent (as opposed to 220 on the extra-course), which I’m hoping will get me through my blades in a much more timely manner. I’ve tried light passes, medium passes, and heavy passes on the DMT and it doesn’t seem to remove that much material.
Any other suggestions on getting my tools lapped flat before going through the grit progression? In my arsenal I currently have the two stones mentioned above as well as a 1000/4000 grit waterstone, sandpaper of various grits, and a ROS. I’ve found that sandpaper wears out too fast for my liking and (apparently) doesn’t get the blades as flat as a stone would.
