Variable angle mitre jig for tight 1D mandrel bends

A two-part block that holds a 1D bend so you can cut it to angle and get the same angle every time. 1D bends are the tight ones, where the centreline radius equals the tube's outside diameter. The scale runs from 15° to 75° in 15° steps. Set the key, butt the bend against it and cut at the face of the block.

Which version do I need?

This block is for 1D bends only. For 1.5D and 2D bends you need the 1.5D / 2D version, or the V2 mitre jig with a slot every 5°. Not sure what radius your bends are? Measure from the centre of the curve to the centreline of the tube and check the table below.

These blocks are sized for OD tube: mandrel bends sold by their outside diameter. They don't suit SCH10S weld elbows, which are made to a different bend radius. For those, see the SCH10S mitre jig.

How it works

  1. Open the block and lay your bend in the bottom half.
  2. Push the key into the slot for the angle you want.
  3. Slide the bend round until its end sits against the key, then drop the top half on. Magnets hold the two halves together.
  4. Mark round the bend at the end face of the block, or cut flush to the face. The piece between the key and the face is the angle on the scale.
  5. When you're done, the key stores in the block.
