power hammer

<< < (2/2)

smiffy:
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
 

tom osselton:
Looking forward to watching your build!

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
