Another day, another project. This time it was wet work. A customer contacted us looking to have a discontinued part for his 2004 Kadey Krogen Trawler 39 foot vessel created. After years of reliable use his scupper flap locks were starting to fail.
Client, "Can you make a scupper flap lock?"
Me, "Of course we can. What is it and do you have a sample?"
Scupper flaps allow water on deck to run off the boat. In certain conditions you may want to lock the scupper flaps so they don't let water on the deck e.g. high seas.
So the client mailed us a sample part. See photo. I measured and modeled the part to precisely match the position of the existing mounting locations and use the same screw size for mounting. I wanted this to be as close to original as possible for fitting.
Additionally, we noticed that the original design used a counter sunk screw head. The kind of screw with an angled shoulder. This was causing a wedge affect and splitting the original plastic by driving the screw through the part like a wedge. Instead we modeled the new part with no counter sink and to accept a pan head flat shoulder screw. This stacks the mounting pressure and compresses the part nice and tight instead of wedging it apart.
In the end we sent a sample part for testing. It fit perfect and passed with flying colors. The client order 10 units.

The client is very happy with his new parts.
