garyc1955 Posted February 3, 2018 Share Posted February 3, 2018 Hello all, have been blacksmithing a while, and want to build an air hammer. Spent a lot of time looking online and like the Kinyon air hammer. Noticed there are many refinements made over the years and would like to know whose plans I should buy. I'm thinking maybe a small hammer, I have a 5horse compressor. Thanks for your time, Gary Quote Link to comment Share on other sites More sharing options...
Jspool Posted February 3, 2018 Share Posted February 3, 2018 5hp compressor should handle a 50-60 lb kinyon just fine Quote Link to comment Share on other sites More sharing options...

Glenn Posted February 4, 2018 Share Posted February 4, 2018 You may want to read the power hammer section on the site. I recall a discussion on the air supply needs of different hammers. Power Hammers, Treadle Hammers, Olivers Quote Link to comment Share on other sites More sharing options...
garyc1955 Posted February 5, 2018 Author Share Posted February 5, 2018 What plans in your opinion should I consider? Quote Link to comment Share on other sites More sharing options...
ThomasPowers Posted February 6, 2018 Share Posted February 6, 2018 Gary; how close to Las Cruces are you? There's someone you should talk with there... Quote Link to comment Share on other sites More sharing options...
Latticino Posted February 6, 2018 Share Posted February 6, 2018 I believe that all 5 HP compressors are not created equal, by any stretch of the imagination. Single or dual stage, tank size, allowable duty cycle, oil-free or needing oil... make a significant difference. In evaluating the capacity of your compressor to run a hammer you will most likely need to know the flowrate at full pressure (i.e. 11 SCFM at 90 psi) and match same with the hammer design. I expect a two stage industrial compressor with electric motor, a 60 gallon tank, and requiring oil will work a lot better for you than a big box special, single stage, contractor , oil free model with a 5 HP gas engine and aluminum head, but you never know.

Hans Richter Posted February 6, 2018 Share Posted February 6, 2018 I start with a single stroke compressor 2.5hp and a small air vessel (6 gal/100Psi) to end up with a big disappointment after several strokes. On the web you will find many calculation tools helping to count the air you need. In my case, I use a 2in bore cylinder with a stoke of 13in which results in a consumption of approx. 105 atmospheric gallons per minute on at least 120! Strokes/min. At this moment I have a capacity/vessels of 85 gallons on 145Psi which allows me to run the hammer 3 to 4 minutes before the compressors (now 2 single strokes) have to run again (after this time your work piece cooled down). The cylinder have to run on at least 95 Psi to create the full impact for a steady contact between the dices. During the choice of the cylinder keep an eye on the fact that you only can take advantage of the half of the stroke/reach of the chosen cylinder because the 'LZ' air hammers pneumatic schema is based on the law of the communicating vessels which means that the max. distance between the dices are 6,5 in instead of the 13 in cylinder range of the cylinder himself. But as Latticino say it depend on so manny factors. Good luck. Quote Link to comment Share on other sites More sharing options...
bubba682 Posted February 6, 2018 Share Posted February 6, 2018 I'm lookin to pull the trigger on a new air hammer i'm waiten for the priced shipped to canada from big blu got the oxygen mask ready...I might need it Quote Link to comment Share on other sites More sharing options...
Latticino Posted February 6, 2018 Share Posted February 6, 2018 Recently used a new BB 110 at my local club. Nice machine which really moves stock well, but in keeping with the general thread I heard that the compressor purchased to serve it cost as much or more than the hammer... Of course the owner may have gone for a bit of overkill there as the compressor is being used for other duties as well, but just something to contemplate.

Irondragon Forge ClayWorks Posted February 7, 2018 Share Posted February 7, 2018 The Blu Max 155 that ESSA has uses an Ingersol Rand compressor that delivers 150 PSI ( 5 HP 15.8 CFM it's "BIG"). Quote Link to comment Share on other sites More sharing options...
bubba682 Posted February 7, 2018 Share Posted February 7, 2018 Im lookin at the 65 thats all i need i got a duel stage 5hp with a 60 gal tank to feed it. Quote Link to comment Share on other sites More sharing options...
