Holding it on the t-square makes sense now that it is mentioned. Obviously
that negates the need for relying on the squareness of the table.

Is this not so?

You may be able to set the triangle on the t-square.

Yes, YOU DO SET the triangle on the top edge of the T-square.


I actually preferred the parallel-arm board version, where you had a
horizontal arm that moved up and down. That way you didn't have to worry
about keeping the t-square tight against the side.

Once you have been drawing for a while using a T-square you can see if it
is not parallel to the lines on the paper. Really not a problem because
you always hold the t-square in place pulling it up snug against the edge
of the drawing board.
