  1. Press Design - To have or not to have 45 degree joins?

    No problem its easier to do it a bit too strong and not have it bend than remove damaged materail and then redo it and a rigid press is much safer to use as well, Enjoy cheers Beaver
  2. Press Design - To have or not to have 45 degree joins?

    Hello there Ross Yes thats much better though you could box in the whole bottom beam which would support the edges better or if you wanted to go completely over the top put stiffeners in and box it with some plug welds to tie it all together, this is what I did when I was making my press though its much bigger and intended for general workshop duties
  3. Press Design - To have or not to have 45 degree joins?

    Hi if if want to do it to a best practice standard then you need to put in stifeners or continue the sides of the H as this is the part of the h beam that carries most of the load and the center part is mostly just to hold the sides of the H apart, And as Jspool said you are making a lot more work and getting a lesser result while probably still strong enough its not the proper way of consrtucting the frame. Cheers Beaver
  4. Dating a MASSEY 5

    Hi Phil I was just reading your post here and saw that one of your hammers is only a couple of numbers from mine which is Y4348, its a 2CWT inslide whats the approx age of yours if you know. Mine was from the invercargill railway work shop Cheers Beaver
  5. It followed me home

    Big gun doctor the blades have stellite tips fitted but the actual blade band is the same material as what the last lot of blades were made from which apears to be 15n20 or such like. The saw doctor at this mill is one of my old motor bike racing mates
  6. It followed me home

    I was out at a sawmill today and did a bit dumpster diving and aquired probably over 100 kg or 220 lbs of large bandsaw blade I think I will give some of it away to a couple of other guys doing abit of forge work
  7. I was given a large piece of 20mm SS400 which was a structural steel and I used it in the guide of the cutting head of a log splitter I made a few years ago and it proved to be prone to picking up and gouging when it wore against its self I think it is intended to have a lot of ductility for earthquakes so it gives to absorb energy. I wouldnt use it again instead I would use just mild steel or a higher tensile steel
  8. Magnetism and Anvils

    Yes I do some thing similar to Frosty, I used to have to go to the local aluminum smelter and after you came back every thing was magnetised which seemed to make any needles from the grinder or die grinders stick out at right angles and stick into your fingers and pulling out a string of spanners out of your toolbox gets old real fast. But anyway my method is to loop up your earth lead of your AC welder into a circle big enough to pass the said items through conect the earth directly to the hand piece terminal set the welder at a fairly high amperage turn it on and pass the items backwards and fowards a few times and it will be done
  9. another new tool from the cave

    When I do it the press often using three pieces of flat bar I call it Joggling, Probably a term of british origin
  10. I have had a very productive day its bucketing down with rain outside but nice and warm in here. It turned out I had a bit too much materail in the centre of my axe billet and it made the axe longer than I first planned but its turned out ok this is my second axe shaped object and first pattern welded axe. I havent heat treated either item yet so could still have a disaster and the pattern will be more vuvid after that as well
  11. Wow Just wow thats so amazing fantastic work
  12. I have a larger version for making 3/4x4 inch rivets that goes in the press, mainly because the tooling needs about 350mm of travel I will have to post it here Cheers Beaver
  13. There is no video of making the axe unfortunatly I will wait until I get better at it first, and nothing apart from a few pics of the tooling I cut the three inch bar down with the horizontal metal cutting bandsaw and then bent it cold in the press which took about 50 tons force as I used two pieces of aluminum close together to get a small radius bend then removed the excess with a cutoff disc and clean up on the linisher platten. I have just found the video that I got the idea from, its in the axe section of IFI have a look "Forging a colonial axe" its a good old youtube vid
  14. Over the last couple of weeks I have been making some tooling to make axes in the power hammer and got to use them over the weekend, It all worked as planed untill my diesel forge burner packed up as I was doing the forge weld. The hand held tools are made from digger track spring so should be a 5160 ish type of steel and the power hammer mounted tooling is just heat treated 1040
  15. Hi Steve I have been thinking about this thread and have read the info you put up and just wish to understand better if i am incorrect. He said that he had annealed the said item and what I have read from some of the other posts along soak my of produced Bainite that was I suggested tempering which is as I understand a differnt process and done at different temps, Heat treatment is not my field of expertese and wish to understand more
