Hi Hermank, surprising as it may seem for such a simple thing, it took a bit of getting my head around the idea. After having a lifetime of using clamps which worked the normal way, the brain is used to thinking that way, and it's difficult to break that thought. Didn't compute for a long time 😁

I made them but not at home...

I made my favorite and well used tools when taking machine shop classes (part of my engineering design career to understand manufacturing processes) at a local school. The one vise, and assort blocks (I made more of these) are steel with ground surfaces. Made them over 50 years ago and use them almost every day, especially for model building.

Simple devise for marking the cutting line when removing excess ply after skinning.
The peace of wood runs along the edge making contact with the chine and marking with the pencil the exact line to cut along

To get small items square, I use a tin sheet plus a load of rectangular magnets, seem to do the trick....

Full sized carpentry tools are too big for some measuring of parts when checking for fit and measuring angles. A set square has 45deg and 90deg angles. A protractor gives various degrees but rather bulky around small parts.

I use these small jigs and tools made up of wood scraps.
