Tube Coping Template

Enter the two tube sizes and the joint angle. Print the template at full size, wrap it around the tube and trace the cut. No printer handy? Use the station table and a tape.

Fishmouth Joints

Mark the cope before you cut.

The template updates as you type. Inches take whole numbers, decimals or fractions, such as 2, 1.66 or 1 1/2.

Tube you are cutting
Outside diameter. Measure it: pipe is named by a nominal size, and 1-1/4 pipe measures 1.660 across.
Its wall thickness (optional)
With a wall entered, the cut is sized so the inside edge of the wall seats on the main tube and the outside stays open for weld. Leave blank to fit the outside.
Tube it lands on
Outside diameter of the main tube.
Joint angle
90 is a square tee. Enter the smaller angle between the two tubes, from 15 to 90.
Offset (optional)
How far the cut tube sits off the centerline of the main tube. Leave blank for a centered joint.
NOTCH DEPTH—
LONG POINT TO MAIN CENTERLINE—
TEMPLATE LENGTH—

For round tube and pipe. The 0° line sits on the outside of the joint angle and the 180° line on the inside; on a square tee both run along the main tube.

Using the Template

Print it true size, then trust the check line.

Print at 100%

In the print window choose actual size or 100% scale, not fit to page. Then measure the orange check line. If it is not exactly 2 inches, the whole template is off.

Wrap and line up

Cut out the rectangle. Wrap it around the square-cut end with the print facing out and the bottom edge flush with the end. The 0° and 360° edges should just meet.

Trace, cut, dress

Line the 0° edge up with your centerline mark, trace the curve and cut away the shaded side. Test the fit on the main tube and dress it in with a grinder.

No Printer? Big Tube?

Lay it out from the station table.

The table under the template gives the same curve as numbers. Wrap a tape around the tube from your start line, make a mark at each “around the tube” distance, then measure back from the square end by the “cut back” amount at each mark. Join the marks with a soapstone and a flexible straightedge.

Templates wider than a letter sheet cannot be printed from this page in one piece. Use the station table, or take the downloaded file to a larger printer.

Fit-up aid. Try it on scrap first. A template gets you close and a grinder gets you tight. It does not size the weld or the joint for load. Have a run of copes to cut? Ask us about CNC tube plasma cutting.
