Hydraulic power has developed a great deal since Dolge's day and what can be done with compressed air can be done in less space with hydraulics. I can see no virtue in a simple antiquated screw press except that it doesn't take up too much space. To be sure, many thousands of sets of great hammers were produced by skilled operators using these machines, and are today, no doubt, by Ray and Serge, but in Dolge's day there were far cleverer mechanical machines at work in Germany and a well-designed pneumatic or hydraulic machine allows far more accurate control of the process. As to the "Weickert-style" felt, I have been following the discussion with great interest and look forward to trying it. Many of the informed comments on the various felts match my own experience very closely and it is great to see a felt manufacturer taking the interest to produce a felt of the old quality.

Good, and let's hope the wool is right to start with and that they can eliminate bleaching altogether. JD
