another reason not to use poplar...if you seal it with BLO the wood will soak up the oils and expand a bit..even if you dont get the plug wet be careful where you store it..
I have some poplar plugs that I made a couple of years ago that are stored in my cellar.. because of the dry winter air, the epoxy has formed bubbles under it as the wood dried out and the plug has shrunk...
