Sometimes one discovers the most incredible garages of individuals tinkering on their bolides. I found one of them, but not just an amateur, because he can restore anything. He has an impressive technical knowledge, skills and machines that are blowing your mind, all in a tiny garage where his great Salmson is stored as well. He has even learned himself the skill to pour babbit and do the line boring to name just a few.

As I was looking around, my eye was caught by a strange looking machine. The man started explaining me what it was and showed a poster which said "New patent. Also your car can last longer". It is a Belgium patent that is not very well known, but after WW2 it was quite a successful piece of engineering and thousands of such pistons were made.

The man of the special garage did see its potential to continue on with this almost forgotten patent. He knew the owner of the workshop Rafeco in Amsterdam who used this pattern. Only one of such machines still exists and he purchased it. You can add a waffle pattern to pistons. This will result in a better lubrication of the pistons. Caused tby the up and down movement of the pistons and helped by the law of inertia at every 'crossroad'  in the waffle patter small 'eruptions' of oil will occur resulting in a liquid bearing all around the piston. 

In the old days pistons had another quality as we have nowadays, but still it can be a very useful to apply the waffle pattern on modern pistons. The vintage engines, often side valves, and with a thermosyphon system often have hot zones that have problems getting rid of the heat. This genius idea will solve the problem.

Your engine is believed to last longer with the waffle pattern and with better compression! Other benefits are less slack and thats great news, because it caused the engine to release heat in a more efficient way as told above. Smoothly the waffle cylinders will cool the oil, connect all points in a balanced way and most of all with less resistance. The motion will be smooth as never before.

While starting the engine it will be running smoothly within a very short period of time. So make your engine happy just apply for a waffle pattern and your car will last at least one more century.
