1.5D Elbow Cutting Fixtures

The GizFab 1.5D Elbow Cutting Fixtures are designed to make cutting tube elbows at accurate, repeatable angles considerably easier.

Designed and 3D printed in-house by GizFab, each fixture holds a 1.5D elbow relative to its centreline radius, allowing your desired cutting angle to be selected in 5-degree increments.

Use the fixture directly in your bandsaw for quick, repeatable cuts, or simply use it as a positioning guide to mark the elbow with a pen before cutting by hand.

Accurate Cuts Relative to the Centreline Radius

Cutting an elbow accurately isn't as simple as cutting straight tube.

When producing exhaust systems, manifolds, intercooler pipework and other fabricated components, the position of the cut around the bend directly affects the resulting angle and geometry of the finished section.

Our fixture provides a consistent reference relative to the centreline radius of a 1.5D elbow, making it much easier to select and reproduce the required cut.

This is particularly useful when producing multiple identical components where consistency between parts is important.

What Does 1.5D Mean?

These fixtures are specifically designed around 1.5D elbows.

1.5D refers to an elbow where the nominal centreline radius is approximately 1.5 times the nominal tube diameter.

For example:

Please ensure your elbows are genuinely 1.5D before ordering.

Tube diameter alone does not determine bend radius. Two elbows with the same tube diameter can have completely different centreline radii.

5° Angle Increments

The fixture allows the desired cutting position to be selected in 5-degree increments.

This gives you a quick and consistent reference without repeatedly measuring and marking every elbow individually.

Simply select the required angle, position the elbow and make your cut or mark your cutting line.

1.6mm Filler Rod Repeat Stop

Need to make the same cut more than once?

A short section of 1.6mm welding filler rod can be inserted into the appropriate indexing position to create a physical repeat stop.

Once installed, simply insert each elbow and rotate it against the filler-rod stop.

This allows the same cutting position to be reproduced across multiple elbows, making the fixture particularly useful for batch fabrication or when producing matching components.

1.6mm filler rod is not supplied unless specifically stated.

Use Directly in Your Bandsaw

The fixture is designed to be held directly within the vice of a suitable metal-cutting bandsaw.

Correctly used, the 3D-printed construction provides a durable and effective method of holding the elbow while helping maintain a consistent cutting position.

The fixture should only be tightened sufficiently to prevent movement during cutting.

Do not excessively tighten the bandsaw vice.

Over-clamping is unnecessary and can damage the fixture.

No Bandsaw? Use It as a Marking Fixture

The fixture doesn't have to be used exclusively with a bandsaw.

Simply position the elbow at your required angle and use the fixture as a reference to mark the required cut line with a suitable pen or marker.

The elbow can then be removed and cut using your preferred method.

This makes the fixture useful for hobbyist fabricators as well as professional workshops.

Ideal for Fabrication Work

Useful for producing:

• Exhaust Systems
• Turbo Manifolds
• Exhaust Manifolds
• Downpipes
• Screamer Pipes
• Intake Systems
• Intercooler Pipework
• Wastegate Pipework
• General Tubular Fabrication

3D Printed In-House

Every fixture is 3D printed in-house by GizFab.

3D printing allows us to produce application-specific workshop tooling at a considerably lower cost than conventional machined fixtures.

These are functional workshop tools, so visible layer lines and minor cosmetic variations associated with the 3D-printing process are completely normal and do not affect their intended operation.

Workshop Safety

This product is a positioning and cutting aid only. It does not replace correct machine operation, guarding or appropriate PPE.

Before cutting:

• Confirm You Have the Correct Fixture Size
• Confirm the Elbow is a 1.5D Bend
• Check the Selected Cutting Angle
• Ensure the Elbow is Correctly Seated
• Secure the Fixture Without Excessive Clamping Force
• Ensure the Workpiece Cannot Rotate
• Check Bandsaw Blade Clearance
• Ensure Machine Guards are Correctly Positioned
• Wear Appropriate PPE

Always verify the resulting dimensions and angle before cutting valuable material or producing multiple components.

12-Month Warranty*

This product is warranted to the original purchaser against manufacturing defects for a period of 12 months from purchase.

Our obligation under this warranty is limited to repair or replacement, at our discretion, where inspection confirms a manufacturing or material defect.

As these are functional 3D-printed workshop tools, the warranty does not cover normal wear and tear, cosmetic deterioration, cutting or blade damage, heat damage, excessive clamping force, crushing, modification, incorrect use or accidental damage.

This product is a fabrication aid. The operator remains responsible for verifying tube dimensions, bend radius, selected angle, cutting position and final fitment before cutting the workpiece.
