Becoming Unhinged
First, thanks for all the comments. Arnold said that there is something about an engine running on steam. I never realized how amazing it is. I like engines that have lots of things moving. Probably why I added a propellor to Elmer's 3 cylinder radial: nothing happens to suggest the engine is even running, other than the rotary valve behind the plexi valve cover.
Adding steam to the mix is like a 3 ring circus. Lots happening in many places.
So back to the build. This is where we last saw the engine.
Actually, it was here, at the garden party.
The upper doors and casting being fettled.
And post-fettle.
I was able to make good use of my woodworking clamps.
With the doors clamped in position, and using the casting hinge pin holes which had already been drilled, these holes guided the drill in making hinge pin holes in the doors.
I did straighten the doors before drilling.
After polishing the shell, I was very careful not to put more scratches in while I drilled for the chimney casting screws.
When I was adjusting the burner flame, the burner kept trying to escape. It really needed something to fix it in place in the firebox. The first step was marking the position for the burner tube in the firebox.
And then drilling in the rear casting.
The Bix Burner in position.
A 1"x1" x .5" piece of brass thru drilled for the burner tube then cross-drilled and threaded for setscrews.
Next, clearance holes for 4-40 brass fillister head screws.
The part was aligned with the hole in the casting and the holes were transfer punched to the rear casting.
Then spot drilled, drilled and tapped 4-40
Another adventure in "Now how do I clamp THIS casting?"
The mount screwed to the rear casting and set screws tightened on the burner tube.
