Fast results from simplicity and warming up the winter with a fan

Target five minutes, we did it! Yes we made it possible. Ives and I made a frame out or two sticks and a block of wood with a groove in which the rubber ring fits. The part of the rubber ring that extends above the groove is cut off. The knife is guided by the top surface of block during cutting. This surface is protected by bits of tin, nailed to this surface.

I had just a bit of luck to find the proper method without the time consuming trying out of the many potential solutions, that I normally have to tackle. I described the result in my last 'News'. Then again I was lucky with the setup that came up when working with Ives. This setup is shown in the picture. Ives told me he had seen it in a recent dream. This is great, a bit of magic, a bit of proper magic when Africa is apporoaching.

What is really practical with this aid is the footrest. This is sadly just not shown on the picture, but it is a simple short stick nailed to the two battens. This footrest gives stability and control over the position of the cutting block at the top. With this device it is again possible to cut easy and safe, and without help of a second person. And it works fast!

Some news this week also on the brick stove. Hans Baarslag build a fan in a box. He and I connected this box to the chimney pipe and fitted it into a window sill. We were too cold and impaitent to properly seal the stove with mud mortar. Thus we lightened a fire in the stove and switched on the fan. There was no smoke pouring out of the many openings, like the first time we put fire to it. But soon there was the welcome warming of the metal covers on the outside of the stove. Half an hour later it felt good to sit on top of the stove. The temperature of the chimney pipe was only luke warm.
Hans and I decided to forget about making a chimney that would produce enough draft through the stove and further develop forced draft by a fan. This fan could run on electricity, but it also could be propelled by the heat of the stove. A simplified Stirling engine would be ideal for this job.
