Thanks Martin, I really appreciate that comment.  This engine looks nice in the pics but great in person. real nice satin shine. Did some more.  Added the engine mounts. Some blocks had 10 mounts, 5 per side. Some had three per side. I suspect that these are 'newer' more recent blocks or the 'oldest' style....don't really know. there was some weakness to the block originally, and a new beefier bearing mount type design was used. The Miss America VII of 1930 had the 5 per side engine mounts. I went with the 3 per side, because you really can't see them.

The whole engine is held together by 8 main 2-56 bolts. Two for the cam covers, two for the heads, and one for the carb ( a single bolt into a brazed 1/4 brass solid rod. rod acts like a clamp and holds the intake together), 2 for the cam flats, and one small bolt for the carb filter.

The solid cam covers have flats milled to their bottom sides which fit milled head surface. The cams are round on the ends, which fit respective cam covers or flats. The flats each have a bolt holding them to the heads. this creates a clamp like effect holding the heads together tightly. The cam covers do not fall out because they are 'locked' on to the head.


waiting on some tiny false bolts to do the block covers....  have not decided how to build the exhaust.  Found some 1/12 spark plugs on the net (sold locally in Ohio USA!!) so bought 16 of them. Did not feel like machining them!   

Tight fit in the engine bay .... and looks scale appropriate!

too many 1mm bolts to count......getting there bit by bit...

RBMotion has some tiny bolts if anyone needs them


Bought a Micromark microlux variable speed   mini drill press and x/y cross slide. eeeeeehhhhhh...hmmmmmmmm. thought the quality would be better. Noisy drill with cheap motor, crappy round belt.  Not impressed as the excellent mini mill is only 400$ more and is 10 times better built.  It is NOT 'jewelers quality(unless you have a bad jeweler).'

BUT, there are only so many inexpensive mini drill presses. It has little power at low speeds. I can drill 1mm holes in aluminum. It is good for SMALL holes. The base and casing is very nice. it works well with the x/y table . the x/y table is made in Japan and has near zero lash. some plastic parts which I did not expect for 110$.  The variable model comes with an electric micrometer depth gauge. not great, does not always work right. you won't need it. the analog variable speed control IS nice to have. The one armed bandit style is perfect.

Thanks Cowboy!  Did the intake manifold.  Could not find a pic so just approximated the design(probably should have been 2 groups of four evenly spaced pipes).    4-40 Mounting stud pressed into supercharger. All brazed w/silver solder.

There are two intake manifolds, one for each cylinder head, and a 'Y' off the supercharger.  I would have included the boost blow off valve springs at the ends of the manifold tubes(cool looking cone shaped springs), but no room in boat, and they would have been hidden anyway.....

Head detail.  Some kind of vent? (x4) on heads, needed two bolts each and recessed profile.  Pics show how I do it 'assembly line' style.  Brass cross braces are pinned in recesses. Brass face up on wheel sander, but sanded roughly to size face down....more stable...then squared up and final sizing on the mill. Slit sawed off one at a time.   

Also made the coolant lines. Semi tapered and mounted with a slant. Made of copper and brass - all silver brazed. Was going to make the little flanges...will see.   

Just waiting on a set of 1/8 scale spark plugs. really wanted 1/10 but can't find them and I don't feel like making them.  the ones I have in 1/12 are too small. will use 28 gauge yellow wire and black spark plug boots!

The plugs are recessed into what looks like a locking sleeve. should be fun to make these last bits. Also, the engine will mount to an aluminum plate base, and the exhaust manifolds will be mounted to same base.  I don't plan on building these anytime soon.  This was just supposed to be a simple conversion. Now with over 100 hours into the engine,  seems like this easy project turned into a real project......(I guess I felt like I had to make more of this model myself)...but I don't plan on ever building another V16, unless it's 1:1 scale!

Thanks guys, that is very nice of you all to say!  Looks like server crash deleted all my pics. will repost.

There are 16 brass castle nuts, and 16 plugs, both countersunk 70 thou.  28 gauge plug wire w/heat shrink at the dizzys and rubber boots (real one had metal plug clamps) at the plugs.

Miller all done!   %%   Enjoy the pics!

More pics of the final detail:

This was a challenging project, and well worth the meditative value.  I will post pics of the final install when done. And of course, pond video (with the Brooklyn tug) as soon as the ice leaves the water

Beautiful engine  :-))

Sorry you seem to be having problems with the site - please keep posting if you possibly can - it does seem odd that you appear to be the only one suffering like this.

I'll say it again - beautiful engine!!   O0
