Set Up & Use

SAFETY FIRST - Please ensure you use appropriate safety gear, such as goggles, mask and ear protection, for the use of your circular saw. Please refer to the manufacturer’s documents for your particular saw and follow safety guidelines that apply for your tool. Also, keep your fingers, and anything else you don’t want cut, well clear off the blade.

Ensure the Circular Saw Sled is placed on a firm flat surface when in use.

Although the product is quite robust, please take care when unpacking.

SETTING UP THE RUNNERS - The right hand side is flexible to accommodate different base sizes for your circular saw. The right hand blocks can be moved and fixed by loosening and tightening the wingnuts.

  1. Raise the Blade to ensure it does not drag on the board.
  2. Carefully set you saw on the centre of the left hand runner and move the right hand runner so that the base rests comfortably on the runners. Adjust the runners until the base easily slides without catching on the runners. When you are satisfied with the fit, tighten the wingnuts.
  3. Place a straight piece of timber up against the top left hand block/fence and ensure that the right hand block/fence is properly aligned and adjust if necessary. Recheck the movement of the saw.

NOTE: You may need to lift the blade guard when pulling the saw backward. If you find that the blade guard drags (forward and backwards), you may need to fix the guard up off the board, for example, with a clamp. Take extra care in this regard.


  1. A 4.7mm spacer is provided. Place this spacer in the channel near the centre of the board.
  2. Place your saw on the runners with the blade directly over the spacer.
  3. Lower you blade onto the spacer – so it actually sits on the spacer.
  4. Lock the blade into position.
  5. Remove the saw off the spacer and remove the spacer.

NOTE: The cut depth is 44 mm as the blocks are 45mm.


  1. Place a block on the inside edge of the left hand runner and a square up against the block.
  2. Rotate the aluminium piece until it sits nice and square against the block and square.
  3. Fasten the wingnut.
  4. Pencil Mark the 90 degree position. You can use this mark to rotate for the angle desired.

For greater flexibility, there are several holes to position the aluminium angle and you can use the above process to set the 90 degree mark for each.

NOTE: It is recommended that you do test cuts to ensure your mitre is to your satisfaction. Refine as required.

Marking The Blade Position - It would be useful to mark a line down the board indicating the position of your blade. This is particularly useful for cutting mitres. You can use the line to indicate the top corner of the mitre.

Cutting Box Mitres - Part One:

The other day I was asked if it was possible to cut box mitres with this jig. This is easy

I set my saw to 45 degrees. As you can see in the video, this lifts the blade above the board.

So, to cut the mitre, I elevated my piece of work up to the blade. I also securely clamped the saw guard out of the way. Pretty cool really.

Cutting Box Mitres - Part Two:

Where do I Line up my material to cut the mitres????

To make a box, you have to line up the edge of your material all in the same place; otherwise it wont be a box.

The easiest way to do this is as follows:

  1. Move your stop block up the right hand fence.
  2. Span your supporting timber across the ditch and against the stop block.
  3. Set your saw to cut at the desired angle.
  4. Run your saw across the timber to mark the cut line:
    • The left hand side of the cut is the BOTTOM of the miter.
    • Use the calculater below to work out the distance from the bottom of the mitre to the TOP of the mitre and mark this position. This will be where you line up your material for cutting.
    • In the case of 45 degree mitres, that distance will always be the WIDTH of your material.
