The turret canopy is attached to the turret cylinder by using 5 #0 x 1/8” pan head screws. One quick note here is to be very very careful with these screws as they are very small, and if one is dropped you can probably kiss it goodbye!! The instructions call for spacing the 5 screws equally around the turret to secure it. I made a quick “cheat guide” for getting 5 screws equally spaced. I used Photoshop to create a 5-pointed star and used that to mark the locations for the 5 screws. With the hole locations marked I used a 1/32” drill bit to drill a pilot hole through the canopy and in to the wood of the turret cylinder. After drilling the pilot holes I used a 1/16” drill bit to enlarge the holes in the canopy only. Using one of the #0 x 1/8” screws thread it into each hole in order to cut threads the pilot holes. Wick thin CA into each hole to harden the threads of each screw hole. Make sure to wait until the CA is completely cured before putting a screw into the hole, otherwise it may never come back out.

In the last two pictures I show the canopy in place and secured with the screws. I am showing this simply to illustrate the completed steps here. I suggest to not attaching the canopy right now, as it will need to be removed for the next step. It’s easier to simply leave it off the turret until the last step is completed.

Pictures
1. Mark 5 equally spaced locations for the mounting screws.
2. Use a 1/32” drill bit to drill pilot holes through the canopy and into the turret cylinder.
3. Use a 1/16” drill bit to enlarge the holes in the turret canopy.
4. Use a #0 x 1/8” pan head screw to cut threads into the pilot holes.
5. Wick thin CA into each hole to harden the threads
6. Canopy attached (see text)
7. Canopy attached (see text)


Until next time
