Trimmer to Benchtop Router Adapter

Introduction: Trimmer to Benchtop Router Adapter

About: Just an ordinary person who loves #thinking and #tinkering

To please my woodworking addiction, I bought a new budget friendly Maktec Trimmer MT-370. It spins at several tens of thousand rpm at no load. Controlling this little beast, we need a strong arm, very strong. Otherwise you will lose control and cut awkwardly.

I have no workbench at this moment. I temporarily work everywhere. On my working desk, on the side table, on the floor, indoor and outdoor. I will make a portable workbench one day in near future. For now I am happy to work almost anywhere :)

As a newbie I think I will make a better cut or round over with my trimmer sitting down on a table and my hands controlling the wood, rather than gripping and controlling this little beast spinning at 35,000 rpm. It shakes the my whole body and I can't hold it properly for too long. Handling the wood with our hands is more comfortable, but you should put extra careful because the spinning blade is now facing your face/head. You should always put on your safety outfit while working.

Teacher Notes

Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.

Step 1: Measurements

It is the plastic base we need to measure. This is what we put top down on the workbench.

  • Base Length = 9 cm.
  • Base Width = 8 cm.
  • Outer Circle holding the machine = 7 cm.

Different machine will have different measurements, so you need to note down yours.

Step 2: Thickness of Wood

Now we measure the thickness of wood compared to the plastic base. In my case I need another layer of thinner wood in between so that I will have the base of trimmer flat to the top layer of wood (benchtop). The top layer and middle layer will have the same cutting size that is 9 x 8 cm, while the lower layer will have a narrower cutting to hold the plastic base of trimmer that is 7 x 8 cm aligned to the center of both holes.

Step 3: Finishing

Mark the bevel out part of the plastic base and cut it out so that the base can go through the board.The lower board has a hole of 7 x 8 cm so it has 1 cm at both sides to hold the plastic base. Align the holes and glue the boards together. Now put your plastic base upside down through the hole. Done!

Step 4: Portable Workbench

As I said before, I have no workbench at the moment. I simply clamp the adapter board on a high wooden stool. This way I can clamp some boards together as jigs. Well, now I am happy to cut or round some edges ^_^

I am thinking of getting a support to the machine to prevent it falling down unintentionally because of loosing plastic gripper. You know that this powerful shaky machine certainly can cause loosing to its gripper at any time.

    Mounting the router into a table is a very good way to work, you may wish to make this safer by fashioning a guard to cover the exposed bit, a few scraps of wood will suffice to bridge over the tip yet still allow work to pass under it and contact the bit.

    Here are some examples of such a device:

    Yes, I need a better guard/fence. Thank you for pointing this out. This is bare minimal version. I am thinking of building a more stable and portable workbench for myself at this moment :D
