    Glad to see you back on here. Nice one Phil, a bit of bog and a coat of paint, an no one will be any the wise except you, and everyone else who reads this forum.

    Hi Phil,
    Nice work. Thanks for the notes on the pictures. Those weights remind me of the ones used on fly presses.
    Best Regards:
    BaronJ.

    Nope, nothing like the ball on a fly press Baron. Fly press balls are for walking into and cracking your skull on.
    These ones are well out of the way.

    The eccentric for the valve gear needed a fitting so I could adapt it to the new wick feeders.
    There is a decided lack of pics but sometimes I forget.
    Any questions just ask.

    About 2 1/2 years ago we had some fatal issues with the Worthington pump used to pump water into the boilers. The rocker arms that actuate the slide valves had some cracks in them so it was decided to make some new ones along with new spools and for good luck I made some new piston rings for the water end.
    We had some new rocker arms profile cut out of some 20mm thick plate which left some machining to make them look (a bit) like the originals. More on them later.
    Here is how the new piston rings were made.

    Phil,
    A great bit of planning that job, nice clear pictures and nice maching. I see you still use a few of the old Whitworth threaded bolts.

    Thanks Bob, it's pretty much all Whitworth as opposed to British Standard Whitworth which makes the challenge a little bit more interesting.
    Luckily I have a book that has all the specs on Whitworth nuts and bolts.

    Next up was the spools though I seem to have misplaced some of the pics of the setup for machining the offset hole.

    No thoughts of making new ones then? I would have thought short of a DRO that would be a more sensible way of having the machine.

    I do like seeing the set-ups that people use to make parts. I'll need to check my RT now to see what the taper is and whether I have an ER chuck to suit.

    Superb presentation Phil and a hell of a job as usual! And plenty of rainy day tricks to save among your numerous setups.

    Thank you

    Hi Michael,
    You couldn't even begin to imagine how high that is on my priority list.
    The centre on that rotary table is #2 Morse so I have made a short drawbar just to make sure it doesn't pop out.

    Hi Phil,

    Super work ! Thanks for the pictures and explanations, I've learnt a lot from those.

    I do have one question though... When you are drilling through a collar, as you show, how do you stop the two parts from locking together where the drill breaks through into the core? I usually have to wrench the two bits apart and hope that it is not too badly scored.

    Thanks:
    Best Regards:
    BaronJ.

    Hi Baron
    Thanks Baron, when drilling through like I did and the drill passes into the stub you have to make sure that your tolerances are pretty tight as any gap will allow a burr and aren't they fun things.
    I had to bore the collar to suit the piston rod on the pump so it was a relatvely easy task to turn the stub to a (borderline) transition fit.
    It's easier if you use some emery cloth but I never seem to be able to get a decent (roundish) journal when I do. I thought cylindrically grinding was a bit over the top.
    A firm fit is the key though not always possible.

    Here is another job on the pump, well the lubricator on the pump. Inside the lubricator body is a copper riser pipe that snapped off (I don't wish to discuss how ).
    To replace this pipe the body has to be separated from the base. To do this without damaging the body I needed a...something, to assist in it's removal.
    The thread on the copper pipe is of course 5/16" BSF, the one die I 'don't' have. .
    No pics of the separation but it worked incredibly well and the boss is in the process of a full set of engineering drawings...as you do.
