Solid Drawing Board

As we in the course of "Engineering Drawing" -Teaching (sounds kinda German incorrect, I know :() took a drawing board, we only this but this year "enjoy" (* cough *) will, I was looking for a relatively cheapest variant and then I came across this one:

In itself, I can only praise these signs plate actually, but that's gripping the drawing sheet with a few obstacles connected:

This allows the left jig retain difficult without autograph keep them open and at the bottom is quite impossible, therefore meaning that you really have to hold both at the same time and then a third arm would need to move the sheet. Well, you get the then chucking out already, but it's not as comfortable as in many a competitor. Where you now not to understand me wrong, it's not infinite difficult grip the blade in this drawing board, it would only be solved better.

Would be better addressed and the second may be the harness related problem: So in most drawing boards down a notch to which one pushes the sheet, thereby ensuring that it is completely straight.
Such a notch located below only right where the second jig. Opposite is merely a marker at the same level, which is intended to help just grip the blade. Unfortunately I can not say that this system works just as well. It takes usually a little longer, grip the blade perfectly.

Otherwise, I am completely satisfied so far and can only recommend broadly this disk when you should consider the points just mentioned.
