Another in a seemingly endless list of tasks that I want to get right. I got this oil door from the aft cowling of a wrecked C336. I took it apart and cleaned everything real nice, then assembled the pieces. I got my best guess meter out and drilled a hole where I thought the dipstick was. After adjusting the hole to be over the dipstick by widening it in the proper direction, I used a laser to give me some lines to draw parallel to the centerline.
