I have obtained a couple of speed reducers ....I think I will use one of to power the swing arm with. the reduction is 6-1, using a 1hp 1375 rmp that would give me 229rpm or beats per min that could be altered using a smaller pully on the moter end. Is there any reason that I should not use these in this way ie: gear box distruction....does anyone know what grease and oil a gear box like this would use? I am now musing over what method to use to transfer the power a disc with a pivot point (bolt)on it or fab up a crank arm are there any advantadges to either one? I found at Princess auto a turn buckle type device used on tractors 3 point hitch I believe? it is 3/4" and the eye ends have what looks like a self aligning bearing in them...this would allow for a little slop in the allignment Not that I will ever need that LOL

I have rebuilt the spring pivot and the bolock to hold them keeping in mind the sugestions here. I also fabed up the hammer top guides. so far every thing seems to be moving smoothly adding some greese nipples will help.right now I am using hex head bolts to hold every thing together when the build is compleat I will sub them out and use allen head machine bolts.

Fristly Jerry that is a good looking hammer .... now on to my junker....not much progress today had to get a couple of roses made up for shipment....I did get the springs cut to length and mounted I think I'll have to shorten the pivots, I made them 4" long probably only need to be 3" we'll see....on the positive side my welding at other angles than flat is improving burning 10 or so #'s of 7018 in a couple of days will do that for you

body metal - rose blanks ,mail box

today I added the upper arm and the guide for the ram...I also milled a 24" piece of small guage rr trank to 3.75 wide for the ram I haven't cut it to final length yet...after making 6 cuts through rr track the bandsaw is paying for itself in no time next up cutting the flat spring to length and bundling them...

it seemed like a good idea at the time...just not thought through the wieght it just too much....ah well more for the "it'll come in usefull sometime pile"

Jerry, I second that please post some pics, any help in my build will be welcome (and needed) presently milling a piece of rr track to become the hammer wieght will post pics later today.

Apprenticeman; thankyou for the information I do have them sourced already I have a Princess Auto store just 15 minutes from my home, and they have the pulleys I need (cheap) :)

its a spring helve...aka rusty/dusty/krusty with modifications as I go...next one will be air:)

First; spend months online going over just about every article and picture of power hammers. (note) Using translation programs for the non-english sites will just confuse you.... just look at the pretty pictures. Second; spend a couple of weeks designing and drawing with exact dimentions the hammer you have decided to build. (note) when you go to the metal supplier to purchase this list it gets torn up in horror, and you imediately drive to the scrap yard and load up approx 500# of assorted parts @ .10 a # Third; decide that cutting any of this metal will need more than a 14" chop saw or a 4.5" grinder with a thin cut blade...result-one 5" swivel head horizontal bandsaw (note) although tool accumilation is good ....it would have been cheaper to buy the metal from the first supplier Forth; say to ^*@% with it and start winging it ah to heck with the numbers some pics of the build so far... I have no idea what the axle came off but the domed flange area works well to bolt it down:) the spline end cut off will come in useful sometime I'm sure...I will update this post as I go, that way someone can hopefully learn from my mistakes.

Ian, I traded some work with a local silversmith a couple of years ago... I made him some security bars for his store and he made up a bracelet for my wife the anvil was my tip I will call him this weekend and ask him the price for one and get back to you if you like Mark

this one is silver 7/16" from horn to heel

heres a link to the one I made microforge my home page is out of date I moved in aug and have not got round to taking new pics yet Mark
