Thanks for all the suggestions.
For what it's worth, I have used a tile saw, it is like a table saw but has a special saw blade without teeth, it cuts nicely and effortlessly, like hot knife through butter, and it has a tub of water underneath where the blade dips into and traps almost all the powder.
However, after having used it for many years, I can say it does not compare to the guillotine at all! The guillotine does not require water and you do not get water splashing everywhere and wet boards when trying to do a cut. The cuts are cleaner with the guillotine, there is less frayed material and copper strands sticking out after a cut. The guillotine cuts in one clean cut, the tile saw requires more effort and guidance.
The tile saw is the best there is in speed and no dust - after the guillotine.
In my opinion once you have used a proper guillotine you do not really want to go back.
My idea is trying to improve on the guillotine by making a better, stronger, longer, more powerful guillotine than the one made and sold exclusively by Mega.
The blades are straight and very easy to make. The base is a flat piece of metal again nothing extra special here. Unlike paper guillotines it is a bypass blade and it is not sharp, so you do not need special tools to sharpen razoe edge blades.
It is quite straightforward to do for someone that has metal working tools.
