Well, important steps done, but thats enough fiddly work for one day!!

Got the screw heads trimmed off and the eccentric straps re-assembled onto the eccentrics. How many times can I drop a tiny nut or screw? Still counting, will let you know! Kept them away from the shop gnomes at least...  Then got the HP arms, bearings, and links all assembled. Needed a couple slight tweaks to the bed in the HP arms to get the links square to the engine, but things are all moving properly. Here is a picture with the parts for the HP reverse gear assembled without the cylinder plate there to give me more finger room. The final valve rod coming out of the link is laying forward on the end of the link:

Then before starting on the LP, I wanted to double-check the length of the arms and make sure things would clear the upper bearings on the crylinder plate supports. Here it is with the eccentric all the way up, and yes there is still clearance between the link and the upper bearing support:

and all the way down, the top of the valve rod is still above the bearing hanger:

 :pinkelephant: :whoohoo: :cartwheel:
That clearance is critical, so well worth checking. The valve rod coming out of the actual valve up above has a smaller diameter, and it screws into the valve rod you see in the pictures with a lock nut on top of the lower rod to keep it in place.
So, all good so far, and next time I'll start on the LP links.  For now, past time to go relax and maybe watch a movie - too cold/wet outside today for much activity out there, which is why I got this much done on the assembly.

Willy:

I've hit a dead end.

I tried searching for "Hughes & Lancaster" + 1898 and got several hits.  The most promising was a lead to the March 21st, 1890 issue of "The Engineer" which had an article on a compressed air tram with illustrations.  My guess is that Hughes & Lancaster did the compressed air system.  That issue has been digitized and is available on PDF - to registered users.  I registered and tried to download the article, but they charge for the downloads.  I've got NO problem with that, and tried to sign up for the 3 download option.  Turns out my credit card will not allow such over-seas shenanigan's. 

I was hoping that in the article we might get a glimpse of the Hughes & Lancaster air compressors and maybe a different illustration.  Maybe somebody on your side of the pond can help out? 

But that article also might just be another dead-end.  I have NO clue why it is that I ALWAYS pick the odd-ball stuff to get interested in.

The Museum  Planners have certainly achieved an inspiring machine for the visual inspection..........those rows of underhead downlighting look similar to the deck downlighting of an ocean liner....& the polished brickwork on the floors  :praise2:

It doesn't really matter what that 'vertical accumulater' type device really was, but some of your responses must be pretty close  :Argue:

Thanks Derek! Yeah, the lighting on the Allis engine is quite good. The basement level with the pump chambers is all painted black with just a few lights, would make a great horror movie dungeon space! 

I've passed along the info plus answers to other questions they had asked about other parts that I knew to the guys at the museum, they were happy for the information.

Hi ron,
If the soft solder doesn't hold up, then the pin would be the easiest fix I think - the soft solder would have to be completely removed to redo it with hard solder, they dont like each other much. If its not hard to do now, just adding a pin should lock it all in place. Either a taper pin or a loctited in straight one would add a lot of strength to the joint.
Parts are looking great! How much more is left to make?

Step one of the bearing block plan done, this morning turned up the eight bearings from all the little offcuts of bronze on the shelf. Well, actually made 9, while deburring the hole on the first one, I dropped it on the floor, and couldn't find it. From the giggling in the wall, I think I have a new shop gnome infestation. Time to turn the polar bear loose again to go eat them (I have enough of a shop elf army at the moment, so it would be a waste of choclate chip cookies to convert more gnomes).   :Jester:
Anyway, here are the bearings all installed in the blocks on the yokes. You can see on the upper surface that the end has a larger flange, on the bottom blocks in the picture the inner ends are sized to push fit in the holes.

The scored lines on the blocks look good as faux joints in the blocks, happy with that. Next step from the list posted yesterday, trim off the screw heads and start the installation sequence. Great place to break for lunch!

Pleased to read that your castings arrived safely Jason.   :ThumbsUp:

For those that might be interested here’s the inspiration behind what will become known as “ Little Otto “

N A Otto, famous for the four stroke cycle was dabbling with atmospheric designs prior to his momentous discovery. The original engine that lived in the Deutz museum went “ missing “ many moons ago. A member of our group decided to make a full scale replica of which I immediately fell in love with.

 :cheers: Graham.
