basher Posted October 24, 2014 Author Share Posted October 24, 2014 getting a 7foot tall hammer upright on your own with just an engine hoist is interesting... Quote Link to comment Share on other sites More sharing options...
basher Posted November 4, 2014 Author Share Posted November 4, 2014 I am sourcing a motor for this hammer. my experience would normally be to over speck the motor as I have found that hammers run better that way. I am very dubious of p the 3/4hp rating from the ad in this thread . I have run 60lb goliath with a 1hp motor but its better 3hp motor a and they run much better with 5hp..... no lag in the motor on pick up. however I am mounting the motor way up high and the less the weight the better. So 90lb spring hammer running at 300bpm will probably require about double (1.87) the power of a 60lb hammer at 240bpm ( if the relationships for speed increase are linear, which Im not sure they are.). I recon that a 4 or 5 hp motor should do it . 7.5 would run an air hammer of a similar size so it should be about rite. I can get a 4kw 1400 rpm motor on ebay old stock unused for £50 so I will give that a go with a small pulley.....weighs around 30kg...not to ridiculous.

basher Posted November 9, 2014 Author Share Posted November 9, 2014 just seen this add for the perfect hammer seems to have very similar double slide feature...... http://www.ebay.co.uk/itm/1913-MACGOWAN-FINIGAN-PERFECT-POWER-HAMMER-BLACKSMITH-TRIP-HAMMER-AD-ST-LOUIS-/331095085009?pt=LH_DefaultDomain_0&hash=item4d16ce0fd1 Quote Link to comment Share on other sites More sharing options...

crij Posted November 18, 2014 Share Posted November 18, 2014 Basher, Don't forget these weren't originally direct driven, so the 3/4HP rating is the loading demand being added to a spinning lineshaft with 100s of ft-lbs of flywheel inertia. This is why you have to up the HP so much to get the impact needed unless you insert some rotating mass between the motor and clutch. Rich C.

basher Posted January 27, 2015 Author Share Posted January 27, 2015 Well I have this hammer up and running, seems to work fine on a 3hp motor at 300rpm at the hammer fly wheel and is incredibly well counter weighted . I have been running it slow to lap all the slide ways in .I will paint it now and re assemble, I think it will be a good hammer. Quote Link to comment Share on other sites More sharing options...
basher Posted July 31, 2015 Author Share Posted July 31, 2015 Well its in and running. Paint is RED not PINK! Here is the broken out slide sideand our fix , forged and welded up mild steel corset , I added 40mm extra to the bottom of the die sides to take lateral force from off centre forging, we added a lot of metal I think its enough. no welding to the original casting.It all seems to slide well , i have not used it in anger yet...
