CL I had the same problem except for me it was too late.
When you turn it
1 make sure of the lengths when picking top and bottom.
2 before you cut the tenon, test fit the spiderweb and mark the blank for proper tenon location.
Also Berea sells other filigree pens with different cutouts. They have them in both silver and gold.
