Building a hatch
The following set of pictures were taken aboard the Kempenaar Libra. It shows how to build a hatch on deck to enter a space below.
The intention was to create a simple hatch. It is practical, maybe not to fancy. There is no option to close it with a lock, but this can be done very quickly.
Positioning the hatch cover to see if it fits
Drawing the corners of the hatch
Combining the corners and you have the lines for your hatch
Burning in the metal. Below are still ribs, so the metal didn't fall
The only option, burning piece by piece till the whole is ready
Welding the four sides
Trying to put the hatch and see if the whole and sides fit
Welding the hinches of the hatch cover on the side of the whole, hatch finished.
