Hi George - yes that's correct, I'm really just after an estimate of it's full force. As far as I know the steam pressure at the site was limited to 100psi - so is that enough info for a ballpark calculation? Thanks for your reply!

Hello! I'm wondering if anyone would be able to answer a question for me in regards to cwt. I'm currently working on a project for the South Eveleigh Locomotive Workshops down here in Australia, which was once the heart of Australia's second industrial revolution and where several hundred trains were built over the course of 100+ years. There's a number of steam hammers and presses that remain, one of which is still used in a functioning blacksmith's shop. It's a 40 cwt double arch steam hammer (since this is British imperial that makes our cwt = 112 lbs), and simply put I've been trying to understand if there's a way to calculate the force of the machine's blow. And also how to compare this to say the force of a manual hammer blow onto an anvil. My understanding is that 40 cwt refers to the weight of the ram - but not the force of the blow. I've read references about double arch hammers having a '125 ton blow' for example. Thanks to anyone who can shed any light on this for me, it's very much appreciated!
