| Original Message: Practice for Fred’s marble |
|---|
|
When Fred first approached me to drill his very large marble I knew that the most difficult thing would be getting the hole centered on each end. Fred’s marble measures 42.7 mm 1.68 inch I knew that the deeper you drill the more likely it is that the drill will wander. I had a marble that measured a bit larger than Fred’s 43.6 mm 1.71 inch that someone other than myself had reworked. I decided to do my trial and error on this marble in case I encountered any problems. I tried drilling from each end to the center and saw that this was not the way to go, but being committed I finished this marble’s first hole in this way and then started drilling in one direction only, in doing this I somewhat fixed an area where the drill went off center. I am going to wait until Fred has his new marble bead and has a chance to post it on BCN, once he does I will tell all that are interested just what I did to get Fred’s marble hole almost exactly in the center of each end. Below are images of my practice marble bead, it is very nice and I am sure there will be someone out there that will want to purchase it in the future. All my best .....................
