Step 4Mod the clear plastic
iImage Information

In looking at the inside of the fine and brush point cpas I noticed the shelf was a little deeper on the brush, so I sawed about an eighth inch of the clear plastic end (yellow line in photo). The fine cap still wouldn't go on, so I pulled out the chisel again. Now on the clear plastic there is a collar like ring, I knew I didn't want to take this all off becasue the lower edge is what keeps the cap on, but I could do without the rest of it, so I chiseled the top portion off (green line in photo).
