Tramming and squaring the spindle

Hi, is there an official method for tramming the spindle ? I have a Mafell one and the 43mm 3d printed adapter that is needed to fit the standard router mount of the workbee isn’t really flat and it’s relative flexibility doesn't allow for a repeatable positioning of the spindle.

I am trying to square it around the Y axis using the 4 screws of the router mount, but I find it hard to fine tune it. For the X axis, I was considering shimming between the router mount and the Z axis C-beam, but I also consider trying to rotate the whole X c-beam on its mounting plates. What do you recommend ?

Thanks.

Hi,

The best way to tram a router is to buy a tramming tool like this: https://www.machine-dro.co.uk/edge-techn...

This will measure how much out of tram the router is. You can make your own version with an indicator dial on a rod.

To Tram the X this can be simply done by adjusting the angle corner positions.

To Tram the Y, also known as the nod, it is more difficult. Minute adjustment is needed. Therefore adding something as thin a tin foil underneath the top/bottom angle corners to get the correct adjustment would work. Or you could shim in between the Z-Plate and X-Plate-Front.

Ryan any chance for a link to the instructions to build your own tramming measure.

@plug_it_in Hi Peter, I am afraid we don't have a link to build your own. But you pretty much just need a dial indicator on the end of a piece of wood.

You can use a precision angle piece, just put it on the table with the verticle arm resting along the spindle housing and check for light along the edge, you may need to drop the z axis to it's lowest. you can put some hard rubber washers under the bolts that hold the spindle mount, or use some small hard plastic erasers with a suitable hole through the center, and adjust the torque on them until the light along the edge disappears. Your spindle should then be trammed. If you are planning to surface your spoilboard you should do this first to avoid the mowed lawn effect caused by the plane of the surfacing bit not aligning with the plane of the spoilboard due to being out of tram.

My goal is to get the router perpendicular to the work surface. I created this heath robinson device from suggestions I saw on the web and it works well. See pic. I spin this in 360 degrees checking where it touches the work surface.

Are you trying to adjust the spindle relative to the z carriage here, or the carriage relative to the x rails? Is it possible that either one of these could be at fault? Some pictures to illustrate where the adjustment should be made would be very helpful.

I resolved the issue by buying a simple piece of 1/4" round bar. Then bent two right angle in it. Put it in router and then checked where it touched the bed. That way I could adjust the router position so it was in the best relationship to the bed. i.e. Perpendicular.
