Could be. I did wipe the shaft clean with 91 Alcohol. Not critical but annoying. Hate when something shows at the last stroke.Probably sanding dust.
Next time add some tint to the alcohol or Danish oil.Could be. I did wipe the shaft clean with 91 Alcohol. Not critical but annoying. Hate when something shows at the last stroke.
I have Denatured alco but too lazy to walk 10 feet to get it. 91 was In front of me. Therefore I pay the dues. Not critical as it's a cane but I'll know for the future.Looks like sanding dust to me as well. Keeping compressed air at lathe - ether via compressor or canister like used for computer keyboards - helps. Thoroughly blast piece with DRY compressed air, followed by solvent wipe. With wood I use DEA -denatured ethanol - instead of 91% IPA - isopropyl - to minimize the amount of water being placed on the wood surface. With porous wood and sanding dust, water is trouble.
Your mileage my vary.
