I spotted the chance for some more detail , specifically the collar at the joint of the manifold to the carb. Cut the 2 apart and fabbed up a collar and used a p/e washer for the collar nut:


Throttle control hardware has been removed from the carb face as well.

 The collar nut should have holes ringing the exterior , just too small to render.
I'm also working through a number of the lines , air , oil , etc....today.
As stated ; fittings from RB Motion are selected and the main oil drain from the front of the cam casing , and one of the lines from the air pump:

These are the ones in the p/e set ad are far from singularly dimensional.

And looking very nice with the addition of a valve of sorts, it separates excess oil from the air supplied by the pump:

The lines are just sitting there adding the fittings and after securing them, a final alignment and clamp to be installed

Some nice detail!

Thanks Gaz!
 Engine detailing continues with a lot to do , the oil separation cannister gets a strap and rivet detail , as well as a drain bolt. 4 Grandt Line bolt/washers were dropped into the engine mounting bolt wells and a tach drive cable mount and 90 were attached to the rear of the camshaft , directly behind the over compress lever:

  And the repetitive question ,asked soooo many times , asked about HV spark plug line...
 FWIW here is my take:
Prym: Too big wrong cross section.
Uschi: Too small and looks it. .005"
EZ Line: Mine has a very poor cross section , like mold-shifted.
Copper wire: Right in all aspects , with the right diameter , problems with attachment and forming.
Steel wire: See copper wire.
So at .008" this is what I have chosen:

Ya I know it says .010" but measuring it , it comes in at .008"
 I used the same PVA glue as before and glued in the bottom lines and one mag line , for testng purposes :

I will also state that it is my belief the fibre tubes to hold the HV wires are scaled too small in the kit as the numbers in scale wont add up. The Uschi rigging elastic material at .005" is the only stuff that will fit in the tubes but it looks way too small , visually , when its on the engine.
I'll put time on it and see what happens, the atatchment is the problem area.

Steve, that is some beautiful detail.  Are you exposing the engines?  It would be a crime to cover them up...   :o

Thanks Lance.
 I threw in a row of spark plugs , using the PVA again and it allowed me to use the edge of a business card again to align after they were all in:

Giuseppe , Andreas , Thank you.
 My go to PVA failed.
So a brand new cyano was opened and tested. The beading line adheres well with that , we'll see tomorrow after The Pull Test.
Mags and distribution tubes all glued up:


And my thinned glue/black mixture gets run in around the plugs and the cylinder bank:

That looks really good! 

Tell me about this thinned glue/black mixture, please.  I'm very curious.

Tell me about this thinned glue/black mixture, please.  I'm very curious.


 Vallejo model air black metal,blue metal and silver  , water , Formula 560 PVA glue , and some laquer thinner to break the tension. Very thin to get into all of the tiny gaps etc . When it dries it shrinks into the gaps etc and colorizes at the same time.
It is working out well on the tiny details of the spark plugs and rocker assy's.
Sorry I cant give an exact recipe , usually when I do this stuff I "paint from the hip" . I did mix enough to get through the job and saved it in a Tamiya bottle.
 A word.
 The Janes book mentioned earlier has a complete description of this engine and its components ,as well as a comprehensive detailing of the systems and how they work. One of these is of the cylinder/head assy's. The description and my experience tells me the c/h assy would have imperfect paint to say the least Therefore some imperfect paint work will be needed. So multiple applications of the thinned paint/glue mix is the way to go for me , with layered application and rough looking work.
