When doing end grain woods cut from 15 degrees to 60 degrees , I will follow this method. First I stabilize the blank and let dry. Next I wrap the blank in duct tape or any nylon reinforced packing tape. Reason for this is to keep your blank together in case it should split on the grain line as you drill. Your grain is running at an angle, and you are drilling in a straight line. After drilling run some thin CA down inside the hole to glue any thin spots or cracks together on the inside. Redrill the blank. Place your blank on the lathe and coat with thin CA on the outside to glue any defects together. Turn your blank until it is round. Coat with thin CA again. Stop the lathe every 2 or 3 passes and recoat to fill any defects. When I reach just over finish size I check the blank and use thick or gap filling CA to give me a more even surface. Now I use a 6 inch fine metal file, with the lathe running fast, and go back and forth to smooth out any high or rough spots. With the lathe stopped, I hand sand lengthwise with 240 or 400 paper to remove any shiny spots reflected by an over the lathe lite. Wipe clean, and sand with 1200 finishing paper and wipe clean. Apply your finishing coats of CA, I use 8 coats of thick CA and wipe on with a soft paper towel, hitting it with accelerator every 4th coat. Now use 400 paper to remove any and all shiny spots. Wipe clean and follow with the 1200 paper and wipe clean again. You can take the polish of your choise and bring your blanks to a glass shine. Jim S
