Ligget I did fill the holes with CA but I also used some of the shavings from drilling and sanding. I had some 1/8th big right to the tube. I painted the blank but I should have painted the tube also. I could see the tube on the some of the big holes even after filling. I call it a learning process . This was my first one with holes. I learned a lot for the next one. I painted the blank Black. I agree maybe a diff. color would have looked better. Rich
