Very short update,
 
I went ahead and added the front wheels and tires, there really isn't any improvement I can make on what was designed before so I when ahead and used those....
 
Here is the result...


There is one thing I did do, I added the camber to the wheels that the original car had... This was a simple matter of tilting the wheels outwards at the top.... The state of automobile steering engineering was almost complete at the time the Wasp was built Proportional Steering, Toe, and Camber had been figured out, the only thing left was Castor.... It would be the early 30's before castoring was understood and universally applied... Until then, steering took actual effort on the part of the driver and needed constant monitoring, one moments distraction and you would find yourself heading in a different direction than you intended...
 
Camber....

Combined with Toe-In and Proportional Steering, Camber allowed the centrifugal sideways force of turning to be applied to downward force as the car turned when the wheels turned, the sideway lean of the inside wheel would become greater in the direction of the turn and less on the wheel outside of the turn... This had the effect of the inside tire pulling the car into the turn against centrifugal force while the outer tire holds the line of the turn.... (this is why in a high speed car making a turn has the outside tire blow out, the car makes an immediate turn in the direction of the blowout, the outer tire is no longer there to hold the line of the turn)
 
Simple applied geometry is all steering is... And Camber was the final part to steering being an advantage in holding the road...
 
I guess I'll head to the rear of the car, I need her to be on all four wheels now.....
 
Onwards...

Thank you Richard...
I was trained in paper and pencil a few decades ago when computers were something engineers only dreamed about, CNC had just arrived in the form of punched tape and I was introduced to doing indexed drawing... (dimensioning a drawing from a single base point) to make it easier to program the tape puncher/reader....
 
The software is actually easy to learn, it just takes practice to get used to it... When doing paper you really have to have the gift of visualization to truly understand what your designing, be able to visualize your part in 3-D... With software that takes the  need for visualization skills to the screen, which eliminates the only real natural drawing talent one needs... All 3D is directly visualized on the screen immediately... The other part is figuring out what type of 3-D drawing you need to learn... the artsy side or the numbers side...  I do the numbers, (engineering) side... There are all kinds of 3D artsy websites out there where the artists display their creations, not too many on the numbers side... But then the artsy side is faster, you don't need the accuracy the numbers side does...
 
Like any software in this field, the initial learning curve is tall, but it doesn't take that long to learn the basics.. I'm absolutely convinced that if someone has an interest and a need for computer 3-D drawing, it's relatively easy to learn and anyone with the aforementioned interest can learn it fairly quickly... (just make sure you got the right software to fit your interest, engineering or artsy they are not the same, modelers generally fare better with the engineering side, but the artsy side can do it as well, just takes more work)
 
Again thank you and welcome to the Log...

And another update....
 
Phew that was intense....

You will probably recognize the speedo mounting post, this is the Steering Arm that slips over the right steering knuckle and bolts to the hex portion of the Speedo post....
 
Below is the Right Steering Knuckle with this part in place....

A very ingenious bit of design there....
 
Was a bear to draw though.... {chuckle}  It's probably not exact, but close.... Very close....
 
And this belongs to the Steering group along with the Left Steering Knuckle and Center link....

And of course it mounts to the front Axel's Spindle carriers....

Glad that one is done.... 
And finally the overall look...

Well more detail take more time... (and I get more practice)
 
This one was a brain burner.... I'm sure someone more experienced in Solidworks would have done it easier, cleaner and faster... But for now, I'm calling it done...
 
Onwards...
Probably ready for Front Wheels and Tires....
 

Why thanks Vad....
 
Yep strong.. that's the Marmon way.... the post was heavy cause it held the bracket which held the spur gear up for the ring gear mounted to the wheel to engage, on the other side it held the end of the speedometer cable....
Here is an image of it from the Marmon advertising manuals of the day....

When originally designed, built and raced, (the1909-10 season) it had a speedo... When they brought it out of retirement for the first 500, (it's only race in 1911) it was left off....

Well another short update.... Front Axle....
 
Been adding the spindles carriers...
Left side...

Right side

As you can see I've started adding the details, the Grease Cups and the nuts for the steering knuckles which on the right side has the Cap Nut with the post for the Speedometer gear... (not present on race day)

Rear side...

Here you can see the round bosses for the steering knuckles which were identical left to right... Once those are designed I will then have to add a very special part, the steering arm... On the first front Axle, I designed what would be on the standard Marmon Speedster, I had no other reference... But in reality, it was a part unique to the Marmon Wasp.....
 
For Example....

Front, low and away and the back side.... it is bolted to the Speedometer cap nut on the front, (which locks it in place) loops around the spindle carrier the over the steering knuckle back near the steering cross link... And it's one part...
 
Time to experiment.... May take a while....
 
But I'm still making progress....
 
The ubiquitous overall view...

 
Onwards....
 
 

Short update...
 
Front Axle... (not complete just a progress update)
 

And an overall shot....

Working out the spindle pivot tubes now....
 
Onwards...
 

Another short update....
 
Lower Rear Springs....
 

It was interesting and a lot easier than doing the uppers....
 
An overall look, Full Frame...

Now I have to go back to the Front Springs and adjust a few details, I found a better way of doing them on the rear springs....
 
Anyway, next up will be an axle, not sure whether front or rear yet....
 
Onwards...

Nice, I hope it brings back fond memories!  I’m not sure what the target market was for these vehicles back in 1972 but to my mind the people in the box art don’t look like a pickup would be their first choice for wheels.

And here we are, the finished Diorama.
 
Thanks for all the comments and likes along the way

Outstanding work. Jeff. Congratulations on your efforts and the awards.

Just excellent, Jeff. Such a beautiful display and well-deserved awards.

Hi guys, sorry for the time lapse since last post, but as l said was on a steep learning curve on limited time to finish her for the Scottish National Scale Model Show in Perth so was under a lot of self inflicted pressure to complete on time, in the end l was working till 11 o’clock at night prior to show, boy was l stressed out, thought modelling was supposed to be a pleasure 👀 glad that’s all behind me. 👍 shall try and keep this final update in some sort of order. Here’s what l meant about paper template to side of hull, easier if it’s slightly heavier card 👍

Once all fitting good to hull, was good to glue foam boarding to 2mm plastic base, just used gorilla glue for this, worked ok. After this next stage was trying to get right colour for surface of water, as this is totally new ground for me thought would try Vallejo USN Blue, figuring it’s got to be a Pacific Ocean sort of colour, wasn’t quite sure though so asked one of the more experienced members in model club for guidance, when he seen it he said it would be to dark, better going for shades of green. So back to the drawing board and repainted, unfortunately didn’t have time to take photos of this stage as l was racing now 🙄 Ray also gave me bit guidance in coating surface with liquitex Acrylic Gel, another first for me, also recommending Yacht Varnish for final covering.

Think at this stage l also started to mark and drill metal frame underneath for brass tubing supports, then started playing with liqitex, cut a long story short, just played around on some off cuts till l thought time to go for it, forgot to say l notched out the foam for the two boats at side of hull before doing this, again using Micro Master boats, modified the 50ft steam Pinnace to make her look different, had this thought in my head of Mikasa arriving in Japan and being fully crewed up from other ships in fleet, hence making the boats looking slightly different. Once the sea surface was dry started fitting brass tubing to metal frame, again using Gorilla glue and trying to keep them all vertical and square. Also managed to purchase a nice piece of wood for base of cabinet, beech l think it is, maybe a bit over top but l think l can get this to work, jigsaw wasn’t a happy bunny though, neither was the wife when she seen all the sawdust in kitchen 😂

Everything seemed to be coming at same time regarding deliveries, fifty foot boat more figures and other things, can’t even mind. Decided to try and alter the fifty foot boat by removing the weather shielding in front of helm and cutting away and altering rear cabin, had a small book l purchased on these boats so used that for ideas.  Was a model changing moment when l removed her from building cradle to fit her to wooden base, all be it very carefully, boy was l glad to see this in place. The boy at bow for anchorage, piece of 10 mm Copper piping, was about right size for me.

Well that’s as far as got with recording things, the rest involved final stages including painting another sixty odd figures, didn’t quite get them all done before show but finishing of her now, will have to approach my excellent joiner for making top piece of display cabinet, maybe when l get started next build log, Bismarck 1/200 for second Son shall slip a photo of her in case. 👍

Thanks guys for following this through to its conclusion, it’s been an experience and a half for me. She also did really well at the model show, have to say floored me, winning four Trophies, boy that was unexpected 

I think I'm reasonably happy with today's results. 
I firstly gave the hull another coat of Ljn Gray as the lighter grays underneath looked too light this morning.
Next I started playing with the algae look by adding SMS RAAF Dark Slate which I applied with a hard brush. Then followed this with a larger brush wash with the same paint. I also started on the deck 'timber look' which I intend covering with hair spray and a very dark grey or even black so that I can weather walking areas to show the timber underneath.
I'm not sure, but I think the green and timber look ok.
 

Some old people like to talk about their illnesses. I Don't! Just say that I didn't do any modelling yesterday and I only started late today. But what a great afternoon it was.
My PE parts arrived today and I primed them. Also I masked and painted the light grey areas of the hull (Weathering will have to wait). It was a pleasing few hours.
Ps. Thanks for all the 'likes' and special greetings to those that are 'following' me.

Hi,
I went on with the cockpit parts. I eventually received the super nice Yahu replacement for the instrument panel which is shown here glued to the other kit parts:

I have added three prominent control levers in the center of the panel made of thin aluminum foil to complete the appearance of the IP. These are the cockpit parts that are now basically completed:

Differently from the instrument panel which was a disappointment, the Eduard seat belts worked fine and added a nice level of details to the kit seats. These are the same parts seen from another angle:

This time, I am going to depict a used aircraft, so I added some grime and dirt by brushing on some pastel powder. Now the parts are basically ready to be assembled, but before I will spray a mist of matt clear to uniform the finishes and mute the glint of metallic parts. On the underside of the cockpit, we have the ceiling of the bomb bay which I also started to color. I first sprayed a black primer followed by a light coat of colors that let the black to be seen through (although not very visible in the picture):

I will finish the bay by adding some more weathering effects to it. Presently, I am preparing the fuselage halves that need to have some of their annoying extractor pin marks to be addressed.
That is all for now, thanks for following,
Dan
