Unfortunately I won't be doing much for a couple of weeks as I am a bit over run with that nasty thing called work . Have a couple of things to ponder . I intend to use a Hydraulic ram as I have one of the correct size and heavy duty air rams are expensive . I am not sure how the seals will stand up but will use plenty of oil in the air . Also intend to use a 5/2 hydraulic valve to control everything as 1/2 bore 5/2 lever operated air valves seem to be hard to find . Finished weight should be about 1 ton The next problem will be on how big a lump of concrete to stand it on A friend of mine who has a modern Sahinier power hammer has it bolted to a block of railway sleepers that sits on a concrete foundation but not bolted down It works well so might go that way. Anyone got a big compressor for sale? Mike |

Made some progress on the hammer guide and ram mounts today. Should be ready for starting to weld it together soon Its starting to get a tad weighty now , the ram guide is all 25mm plate and with hammer shaft weights about 150kgs Next I need to obtain some large lumps of steel for the hammer head and anvil block ,need 2 blocks of steel about 150 mm square . http://www.anvils.co.uk/ sell tooling for power hammers but at about £250 a piece which is a bit more than I want to spend . I will try and get some railway track to modify Mike |
