Hello all, my first post here and I will start by apologizing if I am posting in the wrong area.
I recently made a wooden handle for an espresso Portafilter out of a nice piece of well dried oak. I finished the wood with BLO and then a good layer of paste wax. After two days of use on the espresso machine, the wood had dramatically shrunk and it now feels like it has never seen a piece of sandpaper AND the wood looks and feels incredibly dry in spaces. As the shrinkage is so bad, I will have to make a new one. So, does anyone have some advice on how I should treat the wood for this particular use? Key things in my mind: the wood gets quite warm over an extended period of time due to the coffee machine (there is a metal rod running through the length of the handle that heats it up), but it also gets splashed with a lot of water when I clean it.
