G'day all,
I have a feeling I may have failed to avoid contaminating one of my water stones with grit from a coarser stone. I believe it may be a result of failure to properly clean the roller on my honing guide, even though I carefully cleaned the roller and chisel with a clean rag and metholated spirits before moving to the water stones.
In short I moved from a fine Indian stone to a 4000 grit water stone and it appears that the initial fine polishing that the stone had produced has been dulled with use. My first test with the new water stones was on a plane blade, progressing from the Indian stone to the 4000 then 6000 grits resulting in very nice shine and a beautiful cut on pine end grain.
After some use I thought the 4000 just wasn't removing the scratches from the Indian stone, but when I tried polishing the chissel back left handed I noticed that there were fresh scratches in the new cutting direction.
I've tried flattening the water stone again with 600 grit silicone carbide paper on glass, but the problem persists.
Does anyone have any advise?
