Thanks to both!
Roger looking great as ever! Don't you just love building engines; I just finished this Hispano-Suissa SE5a engine kit for Model Expo which should be available later this fall in 1/16 scale.
Keep up the great work you are doing.

Yes it is. :-)
Thanks for your comments, Ken!
You also did a nice engine; somewhat older as the V-16...(I could read the date: 1917; was probably used during WWI.)
Roger, yes this one is going to be in a SE5a British fighter plane from WWI 1/16 scale model kit. It was also used in Wolseley race cars after the war. Some of which could be great as scratch built subjects.
Ken, thanks for the info!
I expected difficulties with that rear manifold and I got them! When the lower tube was done, I did the tube for the last cylinder, going down towards what was already done. However, the diameter from both parts is not the same. I did a tail at the upper tube and adjusted it at the lower one. When I was satisfied, I could silver solder both elements. Then, I silver soldered the flange at the cylinder head to the upper tube. This operation was delicate: if the assembly is crooked, the tube will be pointed in the wrong direction. By chance, that soldering went well, even if I had to "massage" a bit the tubing assembly. Then the more delicate job: merge the horizontal tube with the vertical one. I did not remove too much metal at once, looking if the job was right. After a while, I came to the conclusion that the horizontal tube was too short. Not wanting to do another one, I cut it and put a spacer about 2.5 mm wide (.1"). When it was done, I had a better vision how both elements could merge, removing metal here and there until I was satisfied. The next question was: how to assemble both? with silver soldering or soft soldering? To silver solder it, I should create a jig; I could however soft solder both elements when they were assembled on the engine.
I now have to shape and solder the two last tubes for that RH manifold.
I noticed that there is an interference between the tube coming from the water pump and the exhaust manifold ( the second picture is showing it well). I will have to solve this issue before I can go to the other side which should take less time to build

By bending a bit the elbow at the last exhaust outlet, I could get the needed clearance. This will also help for the exhaust routing near the gear box. There is also not much space between the rear manifold and the water pump; according to the various pictures, the distance is really short.
With that issue solved, I could solder the remaining outlet tubes on the manifold. The LH rear manifold will be (I hope) easier to do!

It sounds like your keeping busy. -I hope you took time off for your birthday? (Happy belated birthday Roger!)
Thank Don! Oh yes, I did not a lot that day and had fun in the evening with friends! (I was thirsty the next day, I wonder why...)
Happy belated birthday from me too, Roger
Thanks Freddy!
With the exhaust manifolds done, I had two possible paths to continue: the carbs or the intake manifolds. I choose the later possibility. The intake parts should be less complex to do; I will see...For the moment, I did the distribution boxes which are sitting on top of the center exhaust manifolds.
I did a small error when I did the holes for the attaching screws: they are a tad too much towards the exterior. Because of that, I could not do the countersunk holes large enough to allow the regular brass bolts I have, their heads are rather large. The stainless bolts have the ideal heads, but are way too short. Therefore, I silver soldered a threaded shaft (cut from screws) to the stainless steel bolts. Another alternative: mill the brass heads at the same dimensions than the stainless steel ones. Making the bolts longer was quicker done, this is why I choose this solution.

It has massive proportions, any idea how much the real engine weighs?
Sorry, I don't know! Don't forget that many elements like the crankcase are made with aluminum.
Even if the intake manifold is simpler than the exhaust one, it took some time to complete the RH side. Now, I just have to do the other side!
