A good overview of the working area for the mark3 furnace. As with previous furnaces there are pits for the bellows operator feet, and the bead maker's feet. In this case Unnr is sitting up on a box to work the bellows. The bellows dynamic for bead work is also interesting. Notice the hand position. All that is necessary with these bellows is to lift the bag and let it go. So long as the second bag starts before the first finishes you get a clean air flow of enough air to keep the temperature up. This makes the bellows worker's job much easier than that needed when smleting iron. Previous Report Next Text © Neil Peterson, 2017 Photographs © Neil Peterson, 2017 Copyright details Contact us |
