  1. Alan, yes, typo in post 5.... It should read 2.2kw ( 3 H.P ) ! :)
  2. If you took your 7 year old car to the dealer that supplied it to you, and they gave it a quick once over and made a couple of mods to it, and charged a mates rate couple of hundred quid for it, would you then expect the dealer to guarantee the work to the person you flogged the car to ???? or would you expect the dealer to say that they have given it a once over, are happy with it, but cant guarantee the car ? If the dealer said to the person that was buying it from you ' give me a bell if you want to chat about the car, and ill take 20 mins out of my busy working day to give you some guidance' for absolutely no commercial gain, would you still call him to >>> on a public forum ???? You have a similar hammer,very helpful. Is it the same capacity hammer form the same manufacturer ? Ive put a few of these into industrial forges making tools, and they are still going strong a decade later doing 8 hours every day. Not exactly hobby use. Very funny on the ebola comments. For what its worth, when someone starts a statement with 'with respect' I usually find it on a par with 'Im not a racist, but' .... ie, you are calling me. I have sold hundreds of hammers, with hundreds of happy customers, and I spend many hours on the phone every week helping people with hammer questions, for no commercial gain, as many members of this forum will attest to. So, with respect, you are welcome to your opinion about comparing my after sales service to a used ebola contamination suit but I think your reasoning is flawed.
  3. we (massey) are the sole UK and Eire agents for Anyang, and distribute the small hammers. The 2x 25 kg hammers being sold in that advert were back at my place a few months ago, and I gave them a full going over (work not guaranteed to next owner though, not that there is anything wrong with the hammers, or my work !). They have had the lube system fully reworked with fine oil control valves, new copper oil lines etc. I did a nice job on them. The bases were not designed or made by us (customer made). The 25kg is a very useful sized hammer. You can do a lot of work with it. They are very predictable. Send me a PM on here if you want any more information about them. Please note that Sahinler is not available as a single phase option in the UK without going down the VFD / phase converter route. The biggest 'generally available' single phase motor you can have in the UK is 2.2 kw (3ph) - The Anyang 15 KG is the only power hammer that is true single phase. (there are the odd tire hammers, sping hammers and converted blackers that have a 1ph motor on them though). I understand Americans sometimes have a much beefier single phase supply, but im not a sparky so cant comment further !
  4. Im a bit late to the party, but a good rule of thumb for most things power hammery is 0.001" per inch clearance. (bearings, pistons, rams etc !) I cant believe it had worn itself 0.100" clearance on the steel ram and only a few thou in the (much softer) cast iron cylinder. It must have been monkey'd around with by a previous owner, ram from a different machine or something ! Look forward to the vids :)
  5. Lots of Massey 2 cwt 'with slides' hammers out there. Not as fancied as the 1 cwt as the anvil is separate, thus you need a foundation for it. You have got no chance of getting a single phase motor to run it. The only way to get the tup off the piston rod on one of these, to disassemble it, is to have the hammer under power, and then use a dolly between the tup and top die block, then strike some blows to release the taper. I would avoid doing it at pretty well all costs!
  6. There are 2 separate subjects going on here...... I will briefly clarify as to my understanding. 1 - We put Fabreeka (type) pad directly underneath the anvil, as a sandwich layer between anvil and concrete. This pad serves 2 purposes. It knocks out some of the extremely low frequency vibration, and it stops the concrete turning to mush. The pad is a replacement for a layer of timbers. The pads is very dense, 90+ shore (you can dent it with your fingernail 'just about' kind of density. 2 - The materials like ' fabsorb' are placed as an isolating material between the hammers concrete inertia block and the surrounding ground. (Again, to my understanding) the 'fabsorb' is something like an open cell foam, with very low load bearing capacity. It is used like a void filler, in conjunction with a denser material (similar to cork) that takes much more of the weight of the concrete inertia block that the hammer and anvil are mounted to. The purpose of this 'secondary' isolation is to attenuate the transmission of vibration from the concrete inertia block to the surrounding ground. Done properly this has the additional benefit of converting the dynamic loading on the underlying ground (usually a concrete slab itself), into more of a static loading - obviously a massive benefit in some circumstances as it will reduce settling of the whole installation over time. If both of the above are done correctly the entire mass will 'squat' a mm or two when the hammer strikes a blow, you wont even notice it. Done badly (frequency of isolators and hammer 'out') you can get all kind of strange things happening. From 'bouncy hammer' syndrome' to much much worse. Makes me smile when people say 'stick a bit of horse stall mat under it, it will be just as good' , as it wont. Doing it properly can cost big ! (ive put in a dozen + hammers to 7000 lb ram on isolated foundations over the years, and many more on standard foundations, by way of my c.v ! :) )
  7. Ive not used the Fabreeka Fabsorb under a hammer anvil. I do not think it is the right material for that application (check with them) I think 'Fabsorb' is more of an open cell foam material. The Fabreeka nitrile pad, and James walkers Tico equiv. ( ? RF/PA from memory) are very similar materials, priced very similar. Owen, the blue stuff (technical name) under your hammer is from a used foundation mat from under a drop hammer that was at Bae Systems or somewhere like that, in the dim and distant past. We salvaged the mat (it was a big one 10'x 6' ish) - sadly all used up now, ive got the very last of it under my 2cwt. Word at the time was that it made the fabreeka look cheap ! Never seen one like it since. Lots of technical information available to download from Fabreeka's website.
  8. Thats about the most ignorant comment ive read in a long time! :rolleyes: The press is truly epic, a shame that the article is basically gibberish. If I got the jist of it though there are individual steel castings around 750 tons used in the construction. That's bordering on unbelievable !! One of my customers is putting in a 'biggie' in Sheffield, UK at the moment. I think its around 20,000 tons. The crown is 350 ton, they were dropping the tie rods in a couple of weeks ago. 16 of them at 58 tons each !! A press 4x that size ? - epic, no other word really ! I watched a 12000 ton make an undercarriage leg for a commercial jet in one stomp once. My brain struggled with how big it was standing next to the monster. 80,000 tons. Cripes ! :blink: can you tell im impressed ? ;) Pound to a penny the Chinese will make a hundred thousand tonner one day. I can't see any other country ever doing it.
  9. They should all rotate. I did check the drawings last year after this thread, and the 2 cwt does not have 3 bands on the valve portion like I eluded to above. It should have 2. I forgot to report back..... Sorry !
  10. What make (manufacturer) is the hammer? I have a bit of experience with the C41 machines. I have found with the small ones, the simplest way to stop them transmitting vibration is to not bolt them down. Ie, put them on a nice heavy fabricated base full of concrete. If its not pinned to the floor, its very unlikely to crack it. You may need to put a couple of pegs into the floor around the perimeter of the base to stop it 'walking' when its running.
  11. Ms Basher will be pleased you have got a Yorkshire hammer :) Looks a bit 'left handed' with the die configuration !
  12. Sorry, Id - I did not mean your forges would rot out in a year or two ! They looked solid , I mean a re-purposed BBQ would probably rot away pretty fast (they do if you only use them for cooking food ! )
  13. I would leave the mesh on, keep the stray sparks at bay if using charcoal ! It will need lining with something - I had a chat with the iron dwarf, who sells simple forges, (well, the lad who was working for him at the IBF), and he said a layer of sand will protect the steel, or perhaps a layer of clay, or dirt ? What ever you do to protect it, I would have a guess that the steel work will rot out in a year or two (sulphur in coal will make sulphuric acid, fierce heat, it getting full of rain etc). Don't worry about it. You will be planning a better 'mark 2' forge after you have used it a dozen times anyway :D So, my advice is don't over analyse it, find a way to blow some air through the fuel and get some metal hot and start hitting it !
  14. IMHO you need to keep it simple for a business plan, how many widgets you need to sell to cover your costs, wages, and a bit in the bank for re-investment and contingency. (widget could be a set of gates, or a fifty quid companion set) It really is as simple as proving 'I need to shift five grand a month to pay you back, and give me some wages' Then 'stress test' your business plan. reduce sales, increase costs until your bust ! then have a think about the likely hood of this scenario happening. Its pretty easy to write a sheet in excel to do this (guessing there are loads of templates available online, but im old skool, and write the formula's coz thats how I learnt in the olden days :D ) A 'starting from scratch' business plan will show you going into debt for a few months at the start - that's why you need funding (their money). Just be realistic with the numbers (and, did I mention stress test them?) I think you have a much better chance of getting funding with some experience, ie, I worked at joe blog's smith shop for a couple of years, and we used to get five grand for 'x' , I can do that on my own in a couple of weeks if I had 'y' assets going for me. Back it up with examples.... The other, slightly grim reality is, you will be very lucky (actually, cack all chance) to get any funding, from anyone, without some 'flesh in the game' (horrible phrase, but applicable) welcome to the 'PG' (personal guarantee). I churn over seven figures, profitably, a year, with excellent history with my bank.(ltd company) If I need credit from the bank to fund a big job or whatever I have to personally guarantee with my home and personal assets! lots has changed since the sub prime lending credit crunch mess. hope it goes well !
  15. the simplest was I have found to describe the operating principle of a 'self contained' hammer..... Take 2 medical type syringes. Imagine the plunger on one of them is the hammer ram. Imagine the plunger on the other one is the compressing piston (which is worked up and down by the electric motor.) Connect the 2 syringes together with a piece of plastic tubing. When you move the 'compressor' syringe' piston up and down, the 'ram' syringe will do the opposite movement !
  16. Is a full set of manufacturing drawings available online ? I have got a whole draw of a plan cabinet full of them !
  17. There is another company in the UK who manufacture and supply parts for the Blacker hammers (Neville Barnes Ltd) - I do not know how / if / when they started with the Blacker business. I do not feel I can distribute what might be commercially sensitive information under these circumstances !
  18. I have got all of the original manufacturing blue prints for the Blacker hammers, catalogues etc. I can only speculate that Massey of Manchester bought them out at some point (Stalybridge is only a stones throw from Openshaw in Manchester where Massey was based for 120 years)
  19. My rule of thumb for what it is worth.... A normally proportioned anvil (such as the one in the link) will weigh about 500lbs if it is 6" across the face (ive got a few anvils over 500 lbs) I think that Stanley tape rule in the photos will be 3" across the base, and it will scale to about '2' to the width of the face, I would guestimate a small 500 lbs max for that one.
  20. not this year, but 'hammered at Moony's' is on my Bucket list :D
  21. Dillon, If someone shows the gumption to spend a thousand bucks with me for my time, and the copying, then spends over a hundred thousand bucks making the rest of the hammer to a 'reasonable standard' in fifty days (when Massey used to take three to six months) I will not only send them a six grand control valve, (free of charge) I will send them a medal, and a job offer ;) :)
  22. Is the 4N the hammer that the bike building bloke of the telly used ?
  23. I have a full set of manufacturing drawings for a Massey 3 cwt, which is a similar sized machine. I will sell you a full set of drawings for the cost of the copying, and a day of my time. (except the control valve, which I will manufacture for you free of charge if you get the rest of the hammer built to a reasonable standard- gotta keep a bit of the secret!). You will have to sign that you will not use the intellectual property for commercial gain. Cant say fairer than that:) drop me a PM when you get a bit further into the project:)
  24. Use a kiss block, dont work full face of the die block. What is the material you are intending to forge ? Setting the travel position on an air hammer foot-pedal is also a completely pointless exercise, and completely missing the whole concept by which air hammers work, ie, the air is a spring. :huh:
