Scratch another one off the list: Pressure gauge in place: Made up the bracket, (drill two holes, bend, & file) made a nut, bent up some tube: And here it is, the plans called for it to be secured at the lower bolt that you see on the right just above the third shaft... having used up almost all of the copper tubing I had on hand trying to get the bends to accommodate that position, gave up and mounted it higher. Although it seems all squint in the picture, it is actually straight... just a weird photo angle. Joe |

I decided that I liked the look of a gear cover, (which Mason did not include in his drawings) so drew gear-sized circles on some card stock and scissored away all that didn't look the part. Once I had a shape that I liked, cut out two of them from some brass sheet. Then I bent up some thin brass stock to bridge the gap between the front and rear plates, and riveted them in place. Added a strip to cover that space, riveted that in place, the soft soldered the heck out of it. After some cleaning up, it looked like this: (I gave all the rivets a good bit of the soft solder as well, then filed the heads off in the clean-up phase of things) I had already silver soldered some round stock studs on the outside of the rear piece, two of them are drilled and tapped for bolts through the horn plate to hold it in place, and the lower one is simply a spacer. I had also cut away all of the inner plate that would have fouled on various things already bolted onto the hornplate. You can just make out some of the thin brass cross-pieces in this shot. At this point, there is a coat of self-etching primer as well. And voila: Joe |

Got to work on the lubricator assembly.... some milling, then set up in the lathe to drill and ream the bore of the cylinder: Then back in the mill to drill two No 65 holes as oil ports parted that off, and then turned some o-1 drill rod (silver steel) to size, and into the the dividing head to cut the ratchet wheel parted that off and and hardened it, then milled up a bit of spare ali as a former for the brass tank parts cleaned up, well fluxed, wired into place, and silver soldered all the other bits were simple turning or drilling, bending and filing... and that's the state of play to date... have to fettle the fit of the ratchet dogs, get the springs sorted, and make up the pipe and valve that join the lubricator to the valve chest, and the lever that rides the valve shaft to actuate the ratchet, then need to make up the pipe that joins the blower valve to the chimney saddle, handles for the bypass valve and the damper control rod, and a pipe for the blowdown valve on the sight glass assembly...and then it's done, bar complete dis-assembly and painting! Sadly, all that is now on hold, as I am leaving town tomorrow for a summer contract in Ottawa... will have the occasional week-end at home, so hopefully will complete those last few bits over the summer and will get to painting in September...
