Great job. You can save a little money on CA glue by using about 1/5 the amount. Most labels advise too much can actually weaken contact. Keep the videos coming.
You could use a tung oil and re-apply it every so often depending on the type of wood and how often you use the pen. Other option is to use Yorkshire Grit which contains bees wax and mineral oil for a similar finish. Thank you for watching!
