Now for something completely different….after shelling out for one of these awesome microchip cat doors
Mark the bars you'll need to cut to get make a square just a little bigger than the cat door opening
Cut where you marked using some hefty bolt cutters - a good excuse to buy tools, it would cost more to get a guy out to do the job, right? For now only cut the bars not the screen.
Make up 2 "picture frames" using mitre saw. The inner dimension should be about the same size as the cat door opening or just slightly bigger. I glued and tacked mine together with small nails.
After assembling the frames prime and paint to make them weather proof
On one of the frames check and mark where you can put 4 screws through without hitting bars.
In one of the frames drill screw holes
Line up the 2 frames and screw the screws through into the frame you didn't drill
Put the screws into the drilled frame and push through the mesh screen to hold it in place. Cut out the mesh, and put some dabs of glue to hold the mesh
Screw on the other frame to clamp it on to the bars
Perform testing
Done!
Nice handyman job! Thanks for sharing.
BTW, where did you get that security mesh door? Thanks.
Cheers Warren, thanks for your comment. The security door was already here when we bought the place but this kind of door is very common here in New Zealand.
