August 2, 201312 yr Thanks John, it helps when we have a quality hammer made by a firm that knew how to make power hammers, the worlds best in my opinion.
August 4, 201312 yr Thanks John, it helps when we have a quality hammer made by a firm that knew how to make power hammers, the worlds best in my opinion. you tryna get some freebies phil ;) I agree whole heartedly great video too.
August 5, 201312 yr No freebies needed Woodmiester, just stating the truth. Best pneumatic hammers ever built.
August 5, 201312 yr Well maintained they do go on for ever, which is a pita when you sell parts for them! 6' of packing tape if the box is worn, a valve disc occasionally and that's it ! Ive seen them do 50 years as 'dummy' hammers (pre form hammers) in drop forges and still work OK - they tend to go full pelt, all day when used like this. There were lots of little subtleties in their construction that you would never know about. Cylinder material has a smidge of Nickel in the CI for example. Radi on the rams were hand mopped with compound and felt to remove stress raisers, I could go on for ages about it ! Im leaning all this from the old timers, and putting it into practice when we make spares (for the ones that haven't been maintained!!)
August 11, 201312 yr As an American I would call those pincer tongs. Great Video thanks for sharing. I use small ones under my 60 kg all the time.
August 11, 201312 yr I posted several weeks ago asking people about best hammer features. That post is missing. One person did provide some feedback and that post is missing. What gives?
August 15, 201312 yr I noticed that too john. I thought it was Andrew oc that replied, but maybe I imagined it....

August 15, 201312 yr Thanks, guys. When stuff happens and the host makes no explanatory comment, either he is unaware or maybe it was on purpose. Seems f'n bizarre.
August 15, 201312 yr John - here's the explanation of what happened to the loss of posts - '?do=embed' frameborder='0' data-embedContent>>
August 16, 201312 yr its a sort of cryptic topic name, i only clicked on it bc of the randomness of "two days time travel" if it had said say "2 day roll back on postes" or "2days of lost posts" that would have been an a bit more of a eye catcher from the information stand point
August 16, 201312 yr Thanks. The unexpected consequences of moving things off-shore (according to the upset/squabbling going on several weeks ago before the long shut down).
August 23, 201312 yr John N, your picture tour of your facility, posted quite a while ago, would be very nice to see again. I remember being impressed with the cleanliness and array of big machines. The clearspace machines seem to be unique to the self-contained hammer world and I'd like to see more of them.
August 23, 201312 yr Hi John L ! Im devoting my energies to putting together a 'medium heavy' machine shop to assist with the forging machinery rebuilds, heres a sneaky peak for you ! :D
August 27, 201312 yr Here ya go John L ! Shot a slightly clearer vid showing the single blow (steam hammer'esq) control on a 3 cwt we have just overhauled. Cant give it a proper bump up and down in auto working as it is barely pinned to the deck, and the 'anvil' is just a loose block ! The main thing I think we can take from this video is that I need a haircut, and could smile more :D
August 27, 201312 yr Wow! I have never seen a self-contained function like that with the levers. How is this done? I am amazed. Thanks a bazzilion. John Larson
August 29, 201312 yr Its a Massey, all massey pneumatic hammers can do that, thats why we all love them so much. They have an air reservoir to facilitate single blow operation. The in slides model can also do single blow but I don't think they had a res, I could be wrong. You're a game man John, with that flywheel whizzing round just behind you, when we first put in our 5 we forged a new top block for it without having the guard on the flywheel, made the hammer driver keep his wits about him. Phil
August 29, 201312 yr Thanks, Forgemaster. It is an understatement to say I have learned an enormous amount of information from this thread. The essay by Mr. Massey in about 1903 to the Manchester Engineering Society (see pages up in this thread) indicates his company's experience with steam hammers prior to their budding work on self-contained hammers. The clearspace models appear to be the best of both worlds! Here in the USA the Nazel (Beche) machines had a clamping mode but no air reservoir. I am unaware of any Masseys here.
August 29, 201312 yr I have used many masseys in other peoples workshops , and never seen one used like that. nor did I know they would do that kind of work. that would go a long way to explain why they are so sought after.
August 29, 201312 yr Author John, you have any steam hammers tucked away in that little shop? BTW the clutch is amazing! I want to know how you tested it though :blink:
August 29, 201312 yr Ive got a 6000lb & 4000lb Erie in the shop ;) John L - when I get a bit of slack at work I will scan the technical documents on how a Clear Space hammer works and shoot it across to you. I was first introduced to them 22 years ago, and to be honest Ive only got a shallow knowledge of the actual working of the valving, its very complicated, Still a lot of head scratching at times ! * Phil is right on the money - A CSPH has an internal resovoir at about 40 psi that the compressor piston pumps up. This is used for the single blow operation. The earlier 'slides' hammers can do a single blow like in the vid above, but it has no 'whump' behind it ! * I can diagnose, fix, build and troubleshoot them, but the actual air workings are still a bit of a mystery sometimes!
