Home made MFT table with extras

[kitui]

The knobs are not square. I think it is important for accuracy that they are square. I am not talking about the screw hole squareness but the body of the knob itself. I checked with a square and they were off of at least 1/16 over a 1". Way too much. I was a great idea which I went for. After a few cut that did not square I figure out what was wrong. It is sad because they were perfect for what I needed.
I am still looking for rod like that because I need to align two surface with 20mm holes. One surface is a jig and the other is the MFT. I could not find any rod that has 20mm diameter in US. Only available in Uk

A few alternatives -

Do you have access to a lathe to turn the knobs square?

OR

If you have a 20mm bit you could drill a hole in a piece of wood and insert the knob into it and hold in place with a machine screw as a 'set-screw' to capture the knob in a piece of wood.  Run that through a table saw or chop saw.  It's aluminum so it would cut and might give you a square cut you need.

OR

Similar to the second idea. capture the knob and touch it on a disc sander to square it up.
