    Just A Little Bushing..

    Re bushed a cylinder eye.
    Customer did not want the spherical ball that normally goes in there...he wanted Brass so Brass it is considering he supplied the blank...plus enough for a spare.

    Eye finished 9.5 bore
    I shrunk the brass in the sleeve with 1/2 inch of brass to hold it in the lathe.
    Gave it .008 shrink
    After cooling put in lathe and finish the bore (140 MM +.008) and the sleeve OD at the same time along with the seal shoulder.
    Flip piece and face to length then add seal shoulder then add the grease channels.

    Gave the assy .010 shrink into the eye.
    This ain't going nowhere.

    What'd the eye look like coming in?
    Usual oblong oval hole?

    ".010 shrink" How is that done? Dry ice? No humor, serious question.

    Don't remember what the the shrink was but used to to airplane rims (DC10's). The race would go in dry ice and the rim in the oven to like 300 or 400 F. Oh and your right you do get the fun jobs. NICE WORK.

    Big azz Rosebud on Propane and lots of oxygen.
    Very loud.
    Heat it up where the sleeve is going till it turnes red.
    Sleeve is .010 bigger than the bore.
    20 min or so.

    Re: Just A Little Bushing..

    You are talking about the steel sleeve surrounding the brass bushing.? Then, after cooling it is sized to fit the bore, and pressed, and welded?

    NO press needed
    Heat sleeve..
    Insert brass
    When it cools it ain't going anywhere.

    Heat eye
    Insert sleeve.
    When it cools it ain't going anywhere.

    Weld is precautionary measure.
    Really not needed if shrink is done RIGHT.

    Re: Just A Little Bushing..

    Zap, what kind of tolerance is there on the bore for the finished piece?

    How do you gauge the bore on the brass while it is in the lathe vs what happens when it it shrunk into the eye? You said .010” shrink fit into eye but I am guessing the bore on the brass doesn’t shrink the ten thou.

    It will make the ID smaller but only by about .001

    Wanted + .008 for clearance so me no worried.
    Didn't even mesure it after finish.
    Not needed.

    Was the welding done while it was still hot or was it allowed to cool completely before the welding? Judging by the size of it, I would think it still had a fair amount of heat in it when the welding happened.

    At least acetone no? I was thinking more like condensed milk but nothing? Not even air?

    Edit: atmospheric air pressure

    I let it cool with a fan on it for 15 minutes before welding but it was still fairly warm...

    I have a question on this bushing you made. The grease grooves going across the face of the bushing, the ones that appear black in this photo, can they be cut at a 45* angle instead of only 90*? Or at ANY degree besides 90*. I'm asking because we have some similar bushings on some hydraulic cylinders here at work, but they only rotate, at most 30* total. Having grease grooves at an angle would help distribute grease better around the pin for better lubrication.

    Re: Just A Little Bushing..

    I did those in the lathe with a rounded end hi speed bit in a boring bar but the bit was 90 degrees off what it should be.
    Take .020 deep cut each time and just advance the compound to the outside groove.

    Only way to put spiral cuts in it it would have to be turning at the same time and I do t know of any lathe that cuts a thread that HUGE if you get what I mean

    Re: Just A Little Bushing..

    OK well it was a thought I came up with years ago when we first had some problems with them. No body in my organization wanted to check on the possibility of getting that done even though some agreed it might help the problem. We were told to just get the new ones made just like the originals. I'm not a machinist and don't know or work around any, so I thought I would ask someone who has this kind of experience. Thanks for the reply!

    What are you projecting as use life of that brass bushing at the end of that cylinder?

    Bore and rod look a bit large for brass if it cycles often.
