1.65 Inch - 41.91mm Merge Collector Tool

This tool can be clamped into a reciprocating saw/band saw to cut pipe for an exhaust merge collector, it enables you to accurately cut multiple tubes with ease and repeatability.

This is for 1.65 Inch - 41.91mm tubing with any wall thickness

It has 0.10mm clearnance all the way round the tube, for ease of installation but also not too much to cause the tube to move when cutting, some prints may require sanding slightly for the tube to fit perfectly.

For any other sizes please message or leave a comment

The listing includes:

11.5 Degree Merge Collector Jig
3.5 Degree Adapter(Increases the merge angle to 15 degrees)
3 Cylinder Cut Marker
4 Cylinder Cut Marker
5 Cylinder Cut Marker
6 Cylinder Cut Marker
8 Cylinder Cut Marker

Examples of 11.5 and 15 degree cut pipes for the various cylinder counts as well as complete merge collectors, I will add the other angles on request as these are to visualise the final merge collectors.

this tool also requires an M8 x 30mm Bolt(Bolt can be longer) and an M8 Nut.

To Use the tool:

Cut a pipe to the desired length(it may need to be slightly longer to be cut in the jig) and slide into the jig, and seat to the bottom of the hole.

Tighten the bolt so the pipe is held firmly in the jig.

Place in jig in the the clamp on the saw so the bottom of the jig sits flat and the bolt facing away from the saw blade

Set the jig so the blade will remove the desired amount of material from the tube from the pipe and tighten the clamp on the saw, then make the first cut.

(The depth of cut on the tube will determin the size of the exit when all of the tube are placed together, cutting more will make for a smaller hole, cutting less will make for a larger exit)

Select the desired cut marker for the number of cylinders you are merging and place onto the jig, then draw a mark on one end, loosen the bolt and rotate this mark to the other side of the cut marker and tighten down the bolt.

Make the second cut, the pipe can then be de bured and the next pipe installed to be cut without having to remove the jig from the clamp on the saw

4 Wall Layers
Speed Depends on Printer
Support will be needed on some printers( Build Plate Only) as i have added some small pockets underneath to reduce print time
Any material will be fine(As long as pipe doesn't get too hot while cutting)
Slow down last layers for better text quality
