  1. deleted my post because I seen yours, did not know it was a fisher but guessed someone who would know would show up soon

  3. hi Kev, im from a few miles north of you in Northants at my place we teach beginners and make tools and historical items for reenactment, visit if you want ( add your rough location to your profile )
  4. the holes only go about 2" deep but I consider them useful
  5. 4 edges with different radii plus the big one on another 4 and 4 sharp edges, some useful holes and divots for riveting and punching, 2 flat faces
  6. well I like it frosty, may have to add that to the wall at my place
  7. you may want to add your general location to your profile as a lot of questions you may ask have location dependant answers
  8. welcome to the asylum
  9. got a bit of 4140 recently and have started work on it its about a 6" cube ( 150mm cube ) first tried it out and it works ok next will clean it up a bit and add a different rad to each edge on one face, the opposite face is left with sharp edges. on one side a couple of holes will be drilled for punching etc and some small divots made for riveting
  10. got a bit of 4140 today 6" by 6" by 13" also getting some 4" square 4140 going to make a few block anvils
  11. can you show us a single sheffield anvil with the S mark not made by Alsop, for example a peter wright or any of the other dozens of makers. and it is a 5th foot not toe ( you may like to check primary sources for that ) The stylized S is the makers mark on early Alsop anvils not on any others both me and John have visited sheffield foundries and know a little bit about them and their products, what are your sources so we can verify where they got the false details from and can correct them
  12. thank you John, this one has a much clearer makers mark than yours ( which for several cleanings and years of use yours has only recently been revealed ). will check measurements tomorrow and think it is 154 pounds
  13. made in sheffield England, we have one slightly smaller which is the main shop anvil. john who knows more about it than me and knows about the maker will prob be posting here later
  14. IF the welding was done perfectly I would still not want to use it for more than a couple of tons and I would test it remotely to double what I was going to use it at and always work out which way things will go for every possible failure point. on something like that I may go up to 1/4" 7018 rods, thicker metal and better design table 1" thick with 4 by 2 box on edge on both sides, some triangulation at the top and when testing it use a dial gauge to see if things move under load yes I sell them, yes it can go across a border. yes your power pack with have an internal valve to change speed but that takes time, even if it is a fraction of a second it means it might as well have been on full pressure from the start. you want limit switches for both top and bottom travel settings and make them easy and fast to set, mine I just spin a nut to change it. also for slitting or drifting you need to add a stripper plate or you will have hot metal stuck on the tool and the cylinder getting hot while you struggle to remove the tool
  15. that sort is ok for a few minutes use, I tested a similar one a while ago and with continuous use the oil boiled in 8 minutes, mine is ok with 8 hours also that is 2 speed which means time to change over, mine is always on full power and mostly it takes less than 1/4 second from the press starting to move until it is fully in contact with the work which would mean for yours to move at high speed and internally change to high pressure would take longer than mine on high pressure all the time. you also need to add a double acting solenoid valve to that pump to control it. will go look at your frame next
