Ford 300 I six model engine

Gentlemen,
Time for an update on the engine. It's down to making small parts and finishing up the intake manifold and head by plugging and contouring. To keep with the overall look of the engine I made a starter and alternator along with the mounting brackets. The alternator will also be used to adjust the fan belt to run the water pump. The starter mounting area took a little work to get the starter in approximately the right position because of the thickness of the bellhousing flange on the back of the block.

Gentlemen,
I have to take a break in the build for awhile as I have a portrait commission to complete so here's the latest update.
I made up the fan for the engine. This required making a set of stamping dies to form the stiffening bead that runs down the center of the blades. I made this from an old aluminum fixture plate. I cut groove in the lower plate to hold pieces of .062 drill rod to form the beading.

I also found that when I made up the first set of blades they were a little too short and that I didn't have any way of holding them to put the bolt holes.
I modified the beading fixture to hold longer blades and I also drilled them in the same fixture while they were located and flat.
To twist the blades I made up 2 sets of clamping blocks. One set to clamp the blades and another to clamp onto the blade a fixed distance away to allow room for the proper amount of twist.

The second set came out to my liking so I put the proper radii on the ends of the blades and also the small bend at the end. I'm assuming this is for some aerodynamic condition on the full sized blades.
The final picture shows the completed blades mounted on the water pump pulley.

I have been admiring your model engine's for a long time. I am a friend of Bob Nawas, we sat across from you over in Ohio at Debolts show. To the people that have never seen the models in person , they run as good as they look! I would like to see some pictures of your shop sometime.

Hi James,
Thanks for the accolades.
Here's a link to a short video of my shop. The only thing that's changed is I have a new mill. The old round column Enco served it's masterly duty for many years but in the end I just got tired of having to pick up setting every time I moved the head.

New mill.

Now I know where your magic is executed.

The latest pictures of your Ford 300 6 look just plain awesome!

Thank you for sharing it and Happy new Year!

Gentlemen,
The engine is running. Having been away for almost 5 weeks I was in a rush to get it running for the NAMES show but that didn't happen. My apologies to those fellows that came to the show to see it running. This is the second running. I fired it up earlier in the week but had a few adjustment and modifications to make.
It seems like the air bleed hole in the carb needs to be a little bigger because it takes too much adjustment on the main needle to go from idle to high speed.
So far everything seems to be working well. It looks like it will need a different seal in the timing cover because it leaks a little.
Here's the link to the Youtube video.

I have just completed the distributor. It has a Hall transistor triggered by one magnet inside. The Hall is controlled by a timing disc with 6 windows milled around the outside. The outside diameter is 1.05 inches.

This type of ignition would work on a Holt 4 cyl like I have I think. Only have 4 windows for the timing disc? What do you think? Thanks John

Hi John,
Sure it will work on a 4 cylinder engine. I even have it on my V-8 and it works great. There seems to be enough coil saturation even at high rpm's because the V-8 will spin 7,800 rpm.
