Looks like we're going to have another great OOB build on steorides(😁) from you Pierre.

I hope you still have a good inventory of this precious Evergreen stuff, I'm on board! 👍

[250 Testa Rossa]

Nice! Can't wait to see how this turns out!

Almost snuck one by me again, Pierre. I have a feeling this will not be as OOB as you had originally planned. Looking forward to more and more of this one.

Trust me friend, this one needs to be a whole lot more than OBB. I got all the Evergreen stuff out and ready to go!

Well, the frame will be OOB. No fancy brass and aluminium here, you are in styrene territory!!! I'll try my best just for you neighbor! 😃

Thanks Maxx, we are starting right now!

[Pierre Rivard]

The right side of this engine is pretty bare, and obviously incorrect. The engine is depicted with looks like a starter, which of course this engine  does not have. The M06 engine had a water pump, dynamo and magneto driven in series through a shared shaft. Most times these were covered by a panel making a big bulge to the side. Some engines did not have the components cover with a flat block side fanning out at the bottom to reach the wider oil pan. I'm going that way.

The period drawing shows the components I will try to replicate, but first the "starter" has to be chopped out without doing too much damage.

The common thread is the shaft and I will be using 1.2 mm rod, which slides well into 2.4 mm tubes which in turn slide well into 4.0 mm tubes

The water pump is first, starting with wrapping half round 1.5mm around a drill bit and then gluing around a piece of 2.4 mm tube. the 90 degree feed is a bent piece of 1.6 mm rod.

The dynamo was simple (so just one pic of it through the build). A 4 mm tube core, a 3.2 mm tube portion with a 2x2x2 block on top and 2.4 mm tubes (about 1.5 mm length at both ends. 0.25 x 1.0 mm starts will be added. Again this construction will allow the 1.2 mm drive to pass through.

I only have one picture of the in progress magneto. I was so absorbed by the search I forgot to take more photos. The ignition on the M06 engine came from a Bosch twin spart ZR6 magneto and twin plugs (left and right of the block). I started by a 2x2x3.2 block core, a 0.38 x 3.2 flat horseshoed to it to replicate the magnet. On the entry side is the gear drive enclosure made of a short 2.4 mm tube (guess what goes into that?). On the other side of the magnet/condenser unit is a small 2 mm rod replicating the duplex coil and on top a combo 4.0 & 3.2 mm assembly for the  12 ignition wire feeds. Again 0.25x1.0 mm straps added over the magnet. The whole magneto measures 9.5 mm. Glad it's done!

Finally last pictures show the completed 3 components and the assembly loosely installed to the block. The water pump grease feeder still needs to be added on this side of the engine

Nice clean scratching, Pierre.  Minimal collateral damage on the block - probably will be hard to see in the final product.

[MarkJ]

You've done it again, oh great one. Removed something that wasn't supposed to be there and added the stuff that was. It's amazing how you find these fantastic ref pictures for something as old as this is. The assemblies you made look just like the ones in the picture.  You're like a finely tuned parts making machine. Your right, this is definitely not OOB. But heck. There aint no fun in building OOB anyway.

Excellent work, Pierre! You're off to a fine start, my friend!

Thanks Ken, yes a little bit of damage to fix or hide

Internet is my friend and I found good material. However I have come up empty on components external to engine and the various hoses & hard lines so I'm trying to replicate stuff I don't fully understand. I'll try my best.

Thanks Andy. I almost skipped on doing these but I knew I'd end up regretting it...

Getting started is the hardest part isn't it. I don't understand all the components and associated plumbing but time to forge ahead and make stuff.

[Pierre Rivard]

One more component on the engine right side done. The coolant pump greaser (sort of...) loosely located above the dynamo. Plumbing and wiring will come in later after paint & assembly.

Starting on the left side I fabricated the roots blower clutch linkage and loosely fitted it behind the carbs. On the real car the actuator is linked to the gas pedal. The pedal's very last portion of movement (pedal to metal mode) pulls the linkage to engage the blower clutch. Extra 80HP thank you!

 

[Pierre Rivard]

OK, making my first call... anybody know what this reservoir and lines are for. Guessing it may me part of oil system of oil distribution to external component like the roots blower... but I'm just guessing. What I know is that it is not related to the brakes as they are mechanical actuated.

 

[MarkJ]

I haven't got a clue but I'm going to enjoy watching you duplicate that maze of tubes and everything else in that yellow box. Can't wait to find out what it actually is.

Indeed, the first step is the biggest! That's one of the coolest things about modeling--by the time we're done with something, we do have a better understanding of those components, no? Of course, in the end, it only has to look right! You're on your way, now, my friend! Your scratchbuilding, as always, brings joy!

[absmiami]

Pre-war Yetti cooler ?

[kensar]

An oil tank would be my guess.  The round part on the top would be the pump and return lines are on the other side.

[AmericanMuscleFan]

Good scratch building Pierre, you definitely have steady hands, I love what I see! 👌

[Cliff W]

Great work so far, Pierre!

Perhaps that device might be a chassis oiling system. 

An email to Revs might be in order, they can be quite helpful. 

Keep up the good work!

Cliff

[Pierre Rivard]

Thanks for the input fellows. Ken and Cliff are pointing to some sort of oiling system, and I could trace one line to the blower. 

But for today, throttle linkage... I think 🥺

I could not resist. Francis has a dime, and I have a dime!

Hi Pierre,

Here is an interesting cutaway I found. Not sure of the provenance but it seems to be in period.
Based on the internal drawing maybe the device mounted on the cowl could be an oil cooler.  Seems an odd place to put it but it could be using engine coolant rather than air.  

What do you think? Definitely a mystery! 

Cliff

 

[Moparman18064]

Some supreme scratch work! Impressive!

[MarkJ]

Makes sense that it could be some kind of oil cooler with a pump in the system somewhere down the line and also that it is cooled by coolant rather than the air. Looks like it has fins like a filter but it's not a filter but cooling fins. Very advanced design for its time for sure.  Will be great when we finally find out what it is.

The best way to try to increase the low value of our poor currency Pierre, I approve of your good gesture! 😁

Beautiful work on the linkage by the way! 👍
