Discussion on "Press tools" at the Edinburgh Section of the Institution

MR. PEET : I should like to ask the lecturer with regard to him mentioning work done with the roller feed¿what his opinion of the hitch feed is, and whether he has had any experience of this attachment ? It is only a small but, I believe a very efficient mechanism. I. would also like to cross swords with the lecturer on the use of gunmetal pillar bushes as against hardened steel. I should think that a low carbon steel pillar, and bush hardened and ground, is much preferable in die sets up to about the size of 12 in. to 15 in. sq., having a collar on the bush protruding above the top ; this will prevent the setter damaging them as is often the case by using a hammer when setting a tool, as invariably it is the bush that bears the brunt; but I agree with the lecturer that in tools of a larger size it might be an advantage, though I still think that is a, debatable point.
