    When Conditions Become Pressing!!

    Hi All, I agree with Ironman that, whenever possible, I would broach the way he has done it and I have done it this way in the past also but there are situations where one has to present the broach to the work in a certain geometric orientation or the shape of the work does not allow for "free"...

    When Conditions Become Pressing!!

    HI All, I think that only I could do it this way. When conditions become pressing! All of the following for only one operation. How to turn a standard bench arbor press into something else. Anyway, the story. I purchased this used bench arbor press some decades ago now and slowly have been...

    Hi All, One final operation, to turn the OD of each valve body to remove any and all previously made chucking blemishes. I made up a chucking piece out of some round aluminum bar threaded 1/8 NPT to hold the entire body by the 1/8" NPT spigot on the rear half of the valve body. Everything was...

    Hi All, The two completed boiler blowdown valves with some of the last construction fixtures. Note how the valve handles ended up for a RH and a LH valve. The valve handles were finished to final thickness by surface grinding and the valve outside contours finished by drum sanding.

    Hi All, One completely assembled boiler blowdown valve. But we are not quite out of the woods yet as the operating valve stem has a "packing gland" to make the valve spindle pressure and steam tight. And herein lies a small issue as I would like to use a compressible EPDM O-ring seal here...

    Hi All, Proceeding with broaching the 3/32" square in the mild steel handle. In steel, the single tooth broach is really a one trick pony as you will see. The first two photos (281,282) show the setup used. I have described this type of operation before in this thread but a couple of...

    Hi All, Proceeding with a tricky layout that of getting the 3/32" square opening in the curved handle for the valve spindle rotated 30 degrees. See the first photo. I really only needed to determine the orientation of this rotated centreline (photo 280) but for interest I have included the...

    Hi All, Further work on the boiler blowdown valve handles. In this regard a new single 3/32" square single tooth broach needed to be made. As usual, 01 was the material used and after forming it was heated to a bright orange and then quenched in oil. I have described this before so no photos...
