DIY Guide: How to Cut and Bend Downpipe Ends for a Shed or House

This step-by-step guide will walk you through the process of cutting and bending downpipe ends for your shed or house.

Required Tools​

  • Combination Square
  • Pencil
  • Left & Right Tin Snips
  • Drill
  • Pop Rivet Gun & Rivets

Steps​

Step 1: Measure and Mark​

Using your combination square, measure 60 mm from the downpipe's end and mark this point clearly with your pencil.

Step 2: Draw the Primary and Parallel Lines​

Draw a horizontal line at the 60 mm mark. Then, using your ruler or combination square, draw two parallel lines above this line with a 25 mm spacing. These lines act as guides for the subsequent cuts.

Step 3: Extend the Center Line​

Extend the center line (drawn at the 60 mm mark) across the full width of the downpipe end. This extended line will serve as your main reference for aligning the cut.

Step 4: Draw the Diagonal Guide​

From the top left corner of the extended guide area, draw a diagonal line reaching down to the bottom right corner. This diagonal line will help shape the bend.

Step 5: Cut Along the Lines​

Using your left and right tin snips, carefully cut along the drawn lines. Make sure you follow the guides closely to achieve a clean cut.

Step 6: Remove Sharp Edges​

After cutting, file or deburr any sharp or uneven edges from the downpipe to ensure a safe and neat finish.

Step 7: Fold the Downpipe End​

Fold the cut section up along the guide line. Ensure the fold is crisp and follows the drawn line accurately.

Step 8: Mark Drill Hole Locations​

Using your combination square and pencil, mark the positions for drill holes along the folded edge. Space the marks evenly for a balanced appearance.

Step 9: Drill the Holes​

Drill the marked holes, using a drill bit that matches the size of your rivets. Confirm that all holes are cleanly drilled and properly aligned.

Step 10: Rivet into Place​

Finally, secure the folded downpipe end using your pop rivet gun. Insert the rivets into the drilled holes and fasten them firmly.

Conclusion​

By following these steps, you will successfully cut and bend the downpipe end to achieve a professional, secure finish. Be sure to review each step carefully, and refer to the pictures for visual guidance. Happy DIY'ing!
