    Batson press

    in Presses

    Posted

    Planning a building a press.

    I noticed that in Jim Batson's book he specs a 2 hp motor, a 5 inch cyl, with a 5.5 gpm pump. is this gonna work? puts out 24 25 tons.

    If I used 2 3 inch bore cylinders on my press would that equal a 6 inch bore in operation?

    They would be hooked up in series.

    Take care TJ Smith

     

    log splitter

    Thanks guys.

    Just another idea.
    I am working with a 20 ton air over hyd jack mini press . It works. But always trying to have better and faster equipment..

    Probably would be better if I made knives instead of equipment.

    Ok where's that craigslist at.

    log splitter

    in Presses

    How about this?

    What about moving a log splitter inside the shop and leaving the engine out side. Can you extend the lines long enough to work?

    About 15 feet.

    To cold to work outside and to much exhaust and noise to be inside.

    What do you think?

    Harley Chain knife

    Thanks for all the good replies. I appreciate them.

    It was a drive chain. Pre 1970 I think . No o rings. I wouldn't try a chain with o rings.

    I thank Ariel  Salaverria and bruce Bump for a lot of ideas.

    Finished my prototype Harley Chain Knife.
    It's a san-mai type construction.
    Has a 15n20 core ,chain on both sides, filled with 1084 powder.
    Then put in a square tube and sealed.
    I used a 20 ton air/hyd jack to press the canister into a flat bar. I then ground it into a knife shape .
    Here is the result.

    Why not a cast anvil

    in Anvils, Swage Blocks, and Mandrels

    Posted

    "I bought a 150# jet anvil brand new paid around $250.
    It is supposed to be cast steel?? Dropped a 1 inch ball bearing from 1 foot it bounced back about 8 inches.
    When you hit it with a hammer the hammer does recoil.
    It will be a long time before I realize it doesn't work as good as it should. Watch out for used anvils: a lot of them have been through a fire and won't bounce a bearing at all"

    I posted this back in o2 wondering why a cast iron anvil isn't any good. People say good for a boat anchor or a door stop.
    Does anybody know why? or are we just like sheep and follow the flock? BAAAAAAAAAAAAA

    I beam mini press

    in Presses

    Posted

    Another version of the 20 ton bottle jack press.
    Decided to try an I beam version as i have worked on some full size heavy duty press made with huge I beams.
    I used a 6 inch I beam for the upright and 4 inch channel for the base. 2 piese of 4 inch channel are not strong enough and have some flex in them when under load. The beam seems to hold.
    The wood being crushed is 2x2 by 3 inch long pine.
    I have changed the upper bolts to 1/2 inch grade 8 and reinforced the base.
    The design requires the upper anvil to be movable on the beam for other uses.
    Your thoughts would welcome

    gas fitting

    in Welding/Fab General Discussion

    Posted · Edited by TJ Smith

    I have a Clarke 180en mig welder. It has a very small tube from the gas tank to the torch. smaller than 3/16 and bigger than 1/8. Must be some metric size.
    What can i do to connect gas to the regulator? How much pressure in the line from tank to torch?
    Thanks for any sugestions
