Step 3Making a window
- Draw a round circle in the middle of the lid, and make the circle as big as possible, but make sure you leave 2 centimeters margin, you need this margin for attaching the glass with glue.
- You take the lid from the case and drill a hole in the middle of the circle that you just drawed.
- You can release one of the ends from the jigsaw and get through the hole...then you can follow the line to create the big hole where the window is gonna be.
- When you've created the hole, you can make the edges smooth by using the file.
- After that, take the plexiglass. Put the round part, that you just got out of the lid, on the plexiglass. Draw a circle around it. Make sure the distance from the round part and the circle is between 1,5 and 2 cm.
- Now you can take the saw and follow the line you just drawed on the plexiglass.
- You can make the edges smooth again by using the file.
- Before using the silicone paste on the lid, you have to clean the lid up a little bit..that way the paste will be a lot stronger. Just clean it up with some toiletpaper or a towel.
- Now it's time to use the silicone paste. Just put a lot of the paste around the hole in the lid. You don't really have to hurry because it dries slowly. When you placed the paste all around the hole, take the plexiglass and put in over the hole. Push it a little bit so there are no spots left without the paste.
- Now you have to leave the lid alone for several hours. If you have the time, just leave the lid for one day. The paste will certainly be dry that way!
- When you think the paste has dried..put the lid back on the case and check it for watertightness again! Im hope it is watertight, so we can go on to the next step...
