Some of you may have seen this on another forum so I hope you don't mind me re-posting it here for those who haven't yet seen it.
(and for anyone who would enjoy a second look)

Last summer our friend and forum member, CrazyDoug, built a nice Nanzy gas engine model from a set of castings he got from Bob Herder.

Fast forward to Cabin Fever 2019...… A gentleman who had gotten a really nice New Holland model engine from me a few years ago approached me at the show and said he was looking for a scale model of a Nanzy engine and would I keep my eyes open and try to find him one. I happily accepted the request and went on enjoying the show not giving it a lot of thought for the remainder of the weekend.

On Monday morning as we left the hotel at 7:15 am and headed home, I remembered the request and also recalled a fellow with a large machine shop had built 4 of these Nanzy models a few years back intending to sell 3 and keep one for himself. I called the shop and and asked if by chance he still had one of his Nanzy models to sell. He said he did and we drove less than an hour straight to his shop. He took me upstairs in his barn where his models are stored and pulled out 2 of them unpainted but complete and in running order.

He said "Here they are. They both look the same and they both run the same. You may pick one and I'll be keeping the other."
A quick visual inspection confirmed what he said....They were identical. He said they run fine and his word is good so no demonstration needed.

Below are some pictures of the engine I brought home.
Video soon to follow (some of you have already seen the video on YouTube)

In the pictures below is a 3 year old engine that was still new and only test run.

Enjoy,

Gil

















A short time later.....

Back home I got the engine set up to run and gave it a test. I had a short
learning curve regarding fuel-air mixer adjustment etc. It ran real good.
I gave it a 4 hour work-out to get it well on the way to breaking in properly.

Then I phoned the fellow who requested it and he was pleasantly surprised
I found one that quickly for him and I shared the story about the stop off
on the way home from the show. I asked if he wanted it unpainted as is
or finished the way I might do for myself in a deep rich dark red with the
outer edges of the cooling fins cleaned and polished.
OR....
Would he like it to be painted black on the crank case
and silver on the cylinder jug just like the originals.

He wanted it black and silver as the original so I asked did he have
an original or have access to one. He said he has one.
I asked for some pictures so I could try to get it right.

Here they are....













Next.....

I kept myself quite busy during my off hours at
the end of my work day and on the weekends.

As I partially disassembled it to begin painting and polishing, I began to
appreciate the very high quality of the machine work that went into it.

a few pictures....

The crank case/fuel tank base was done
with 5 coats of black lacquer and 3 coats of clear.

For the cylinder jug I wanted something less glaring than the typically too bright silver spray paint so I visited a nearby automotive paint specialty store and came up with a modern 2 coat wheel paint that is a very fine grained metallic yet darker shade of silver. I believe it may be a urethane and it requires the clear top coat be applied right after the base coat flashes or the clear coat will peel off. This means it must be cleared about 25-35 minutes after the base coat (with the color) is applied.

At first I didn't know this and after the base coat on the jug set up, I went about prepping and painting the crank case with all the layers of black lacquer. Now I thought I'd be smart and reassemble the engine and then clear-coat the whole thing all at once....wrong! 

So once again I removed the cylinder bore from the rest of the engine and called up the paint manufacturer for a little tech support. I scuffed the surface of the hardened paint on the cylinder jug and added another fresh coat of the base coating. Then I waited 35 minutes and clear-coated the fresh painted piece. Then left it to harden.

Back to the crank case casting.... I clear coated the now 3 days cured black lacquer with 3 coats of clear.
Did the same with the flywheels.

Polished what I could of the brass and re-assembled it and below you can see the result.

Enjoy,

Gil

With JB Weld... I also filled in the trenches in the crank case casting where the holes
through the upper flange to accommodate the 2 bolts holding the cylinder block in
place were bored deep and a little close to the edge so that when the builder
ground down the casting ridge, the holes were exposed.
No problem, now good as new... or better.

I also replaced the modern off the shelf bolts with more appropriate tall domed hex bolts.
Paul Debolt of Debolt machine is sending me four similar bolts sized 5-40 to replace the
screws holding on the side cover of the crank case.

Here are 2 videos....

One before the paint and polish work and one after and a little better adjusted,

Enjoy,

I really like this one and what you've done with it Gil, but not as much as I like that Märklin in the background that I missed out on with Pook & Pook  ;)

I've always liked the Nanzy model. This one has turned out particularly well. Great finishing work, Gil!

Thanks, Carl. Actually most of these pictures are from Photobucket.
And yes, I have been able to post pictures direct to the forum thanks to your discovery.
I still can't get MrsRedRyder's account to post direct full sized pictures.

Thanks, Nick.... If I ever let go the little Marklin I will let you know.

Thanks, Rog! It is a neat little engine. As it morphed into a nicely finished piece, even Mrs Red Ryder was thinking of keeping it. However the commitment to deliver had already been made before the finish work. It present owner is just plain thrilled with it.
