The pivot point drilled on the left, two holes are drilled and tapped 5.077" from the centerpoint to make the quadrent notches on a 5-9/32" radius.
17-Aug-2011 With the angle plate held in the vise, we use the 8-32 hole in it for the pivot point.
Bill didn't like clamping the edge of the angle plate in the vise--it puts a lot of twist on the movable jaw and is a small contact point--so a scrap metal bar…
No, he's not holding the plate in place while we machine the slots, the c-clamp is doing that. But he is feeling how the cutter is doing and feeling for…
17-Aug-2011 The revering stand with notch graduations cut. The first notches away from center are 1/2" apart. The notches are 0.040 wide and 3/32" deep. They…
24-Aug-2011 Using a #78 drill bit to drill the spring hole in the handle with a sensitive drill attachment.
24-Aug-2011 Using such a small drill (#78) called for the fastest speed on my Bridgeport, which in this case is 5,440 rpm, quite a lot faster than a standard…
Milling a flat in the throttle handle. We decided not to use the 1/8" flat bar stock design, opting for a round lever. 1/2" 303 stainless steel, big enough to…
27-Aug-2011 I finished up the clevis links over the weekend. The boiler bracket is 2-3/4" long instead of the stub shown on the print to bring the throttle back…

24-Oct-2011 Back to assembly! The now shorter manifold is (re)-installed on the boiler. On the right the main steam gage fittings have been installed, on the…
24-Oct-2011 A special Adapter Union! 1/4 MPT on one end, 5/16 MTP on the other.
24-Oct-2011 Using the union as a holder, we make some close nipples. Here we are facing the brass pipe to length before threading.
24-Oct-2011 With adapter unions and adapter bushings installed, we begin to ponder how to position, place and pipe the waterglass.
24-Oct-2011 The left side of the cab next to the end of the turret is going to be a crowded place in regards to plumbing. We will try to sneak the water glass…
1-Nov-2011 Taking a little off the top. Although we measured the distance from the boiler fitting to the manifold valve, the exact distance to match the union…
1-Nov-2011 The blower valve is installed. I can't believe this fitting took us one night to install, but it did. Shown is the custom 1/4 tube compression elbow…

18-May-2012 A little more lathe work and with the help of a 5-40 die, I've put threads on the end of the extension rod to tightly hold the handle to the stem.
18-May-2012 A little bit of heat and some silver solder joins the stem to the disk with one of the nicer looking soldering jobs I've done in a while.
18-May-2012 We've decided the valve stem extension should have pins that stick down and engage the webbing of the original valve handles. The oil valve has an…
18-May-2012 I've centered the extension in the mill and determined that the pin spacing should be 0.180 over from center.
18-May-2012 All three 3/32" diameter pins (5/8" long) have been pressed into the disk and engage the handwheel spokes with little slop.
19-May-2012 I didn't want the atomizer handwheel to be the same size as the fuel handwheel, even though they are both identical. So I install the handwheel onto…
19-May-2012 The modified atomizer handwheel. A bit of handwork with a small file to take the sharp edges off gives a distinctive handle gloved hands can easily…
