Rick,

The rear wheels shown in the pic are 0.670" dia where the tire mounts and about 0.400" wide. I choose them because they expanded the Vintage F1 tires to the desired diameter of ~1.140". If needed, I may be able to turn them down or source a smaller wheel. I also have a .600" wheel available to use if it fits better.

And yeah, PM's descriptions of the tires and applications are poor. Four e-mails and two phone calls to Andy and he can't help me out either

 

Dennis,

I suspected they may be smaller, but as said you can't tell that by the tiny thumbnails most vendors post in their catalogs. That's another reason I thought the Monogram or K&B tires might be a better choice as they simply "look" larger. Either way I am open to opening them up

 

Regis,

Thanks for the link. They do show the dimensions for most of their tires, so that is a helpful resource as a cross reference.

 

Thanks for all your help guys, to be continued...

Hi Bruce,

 

I will see if I can mount a russkit tire on a wheel similar to yours and give you the specs on it today.

 

Is the .400 dimension the wheel width inside the flanges or the outside the flange overall width?

Bruce,
 
The Russkit tires are designed to fit on a wheel that's about .100" smaller in diameter than your wheel and only .340" wide. I have K&B wheels that are similar in size to yours and I was afraid if I tried to stretch the Ortmann Russkit tire over it I would break the tire.
 
I'm running the K&B Goodyear Stock Car Special repops on my car. They are made by Paul's Slot Car Shop in Canada. I get them on eBay. My wheels are .400" wide overall and the tire mounting surface diameter is .650". They are a little narrow for the wheel but I just filled in the gap at the back of the wheel with the same adhesive I glued the tire on with (Permatex Flowable Silicone Windshield & Glass Sealer):

 

 

 

My overall diameter after I ground the tires just enough to true them up is 1.135"

 

I'd rather be running a Dunlop tire too but...............

 

[Bruce Wayne]

Rick,

This is just the kind of feedback that I needed, thanks so much for your time and efforts.

 

Yep, I had thought the Russkit tires might be too small. Phillipe told me months ago when I showed him the project that I would have trouble finding a big enough tire.  E.D. sells re-pop Russkit wheels that I think go with those tires, which they show as .560" where the tire mounts, so that was a vague clue too.

 

Anyway, the rear wheels I mentioned above are .400" wide overall, .340" between the rim beads, and again .670" diameter where the tire mounts. Since they are nearly the same as yours +.020", the K&B tire could be a good choice, and hopefully turn out to be a tiny bit bigger overall too.

 

Time for more research...

[dc-65x]

Hi Bruce,

 

PdL is right about the big Benz-O needing big wheels to look "Korrect". But, it's hard to find the parts we need and sometimes all we can do is the best we can. The Russkit wheels are pretty small in diameter for older cars and with the Russkit tire the overall diameter is only about 1.080".

 

The K&B's should work good for your wheels. You might want to try the urethane tires made by Paul's Slot Car Shop available on Ebay. He has them in different hardness too. Here's the link to his K&B's:

Rick,

 

Thanks for the link! That was too easy.

I've promptly ordered some up because at that price they are certainly worth a shot .

 

This is about where the Big-M project is at and there is still a long punch list to check off, so I'm in no rush to set a deadline.

While waiting for the tires, I've put on what is hopefully the last coat of white to seal the primer and wood...

 

[dc-65x]

Good Grief Bruce!      Is that your carved wood body?    What amazing detail....it looks like an injection molded model kit body!!!!

[Regis4446]

Here are photos of the 1955 BRM my very young friend Nicolas who made the wooden body frame and rims

Beautiful and beautiful

[Bruce Wayne]

Very nice Regis, Nicolas should be proud of his work

 

The starting grid for this race is shaping up to be quite a spectacle.

[Bruce Wayne]

At this stage, the body has received two coats of Tamiya Spray Lacquer in Metallic Silver, decals from Patto's Place followed by two coats of clear lacquer...

 

 

 

 

After decanting the silver from the can and spraying it through an airbrush, the surface dried nice and smooth, so it was practical to apply the decals directly onto the model without having to first apply a clear coat.

I must say the decals from Patto's place worked very well and I'm pleased with the results.  Although quite thick they are very opaque and stood up well to my rough handling. By using a combination of Micro Set and Micro Sol decal setting solutions I was able to stretch them over the egg shaped rear bodywork with a little fussing and finesse.

 

The instructions that came with the decals and all advice from other modelers cautioned me to only to use Future Clear Acrylic over them, but I prefer to use old fashioned clear lacquer over decals for it's hardness and durability.  To make sure it was going to be compatible, I first test sprayed a wet coat of clear lacquer over some extra decals from the same sheet. The results were good as they were not dissolved or adversely effected by the lacquer, so two good coats were applied over the decals to finish model's topcoat.

[Jairus]

Bruce,

That is looking beautiful!  Decals are great and the shape screams Mercedes.  

Wish I could say that things are going well for me.
Been a hugely disappointing last few weeks financially, spiritually, socially and humanistically.  I've lost money, time and my complete faith in humans around me. Unfortunately that tends to affect my creativity and so... the most I've been able to accomplish is getting Juan Manuel Fangio positioned in the cockpit and the wood rimmed steering wheel placed in his able hands.
. 

Still need to install a steering wheel hub hub of course,.... and a few other details to add before twisting open the paint jars. But I'm getting there.
Might be a fun thing to do tonight.  
Ciao
 

[SlotStox#53]

Sorry you've had a less than perfect couple of weeks Jairus, if its any consolation your Maserati is looking out of this world

Cant wait to see it wearing its top coat!!

[dc-65x]

I agree Paul.

 

Jairus your car is looking incredible. I have some projects that I'd love your help with and hopefully they would help restore your faith in people because you WOULD get paid for your hard......work as long as: 

 

"Do you accept... Cash? Cha-ching"  

 

 

Seriously, I do have some stalled projects.

[Jairus]

Always willing to help you Rick! 

[dc-65x]

Thanks Jairus,

 

I have projects that I really like but they need the bodies and interiors to finish them. You do it all but I just love to do the mechanical things. I tend to finish the mechanical part and then the project stops......

 

When I'm recovered from my eminent medical adventure, maybe we can put our heads together to finish them up and maybe, start some new ones!

 

Rick

[Jaak]

Just thought I would let you all know I am (still) working on mine.

This one is V2.5   ..V1 the dog killed  V2 was way to big V2.5 is properly sized just needs detailing the curves and headlights of the TR3.

 

I bought a 1:24 plastic kit of the Triumph TR3 and then discovered my V2 was way of scale,

will see if I can use some of the plastic bits like the grille for my model.

[Bruce Wayne]

Ready for Tech inspection...

 

Notice anything funny with the motor Rick?

[dc-65x]

WOW!

 

Absolutely fabulous Bruce!

 

The motor looks like a Pittman 196B with a Mabuchi 16D style axle bracket attached. Now you can run whatever crown gear you like

 

Did you make the wheel inserts from Strombecker plastic wheels?

 

K&B repop rear tires on what wheels?

 

Nice car!

[Jairus]

Most excellent Bruce... and, you got your's done before me. (drat)

Passes tech with me.  Now get some of the best "Hollywood" shots together so I can post them on various forums for the Concours when the time comes.
 

I like that you cut the legs off that 196B motor. I see someone was paying attention to my built.... 

 

Who made the driver figure?

[garyvmachines]

 X- elent  Work Bat Man

That is Beautiful Work Bruce !!!!!  Good luck in the race !!!!!

From  all in St Lou...........

 

GAV

[slotbaker]

Wow... chaps. That is going to be on spectacular starting grid with all these cars lined up.

[Bruce Wayne]

Rick,

Yep, it's a 196B with the axle mount arms cut off ala Jairus's tip, but look a little closer (please excuse my crummy photos) at the motor frame/magnet poles. Dennis Sampson told me an old Pittman hop-up trick was to take an old motor, cut off the sides and double them up on your good motor for more field strength at the armature. Dennis also did me a great favor by static balancing the arm and reassembling the motor. The motor bracket itself was scratched out of 0.032" brass sheet.

 

The wire wheel inserts are from Andy at BWA in 1/24 scale. I ordered all three sizes available, and used a variety of them to get the right fit. As for the wheels, I have no idea who made them. I had a front set of almost perfect ID, and they featured a nice step on the rim lip too. Found a suitable OD rear set, but had to turn the ID larger to fit the inserts and also had to turn the step on the rim lip. All machining was done by hand on a tire truer using an Exacto knife with a #11 blade as the cutting tool.

The rear tires are the K&B Goodyear repops from Paul's that you linked me to, fronts are Ortmann Vintage F1.

 

Jairus,

I beat my head for a week wondering what kind of gears I could find/use on a 196B, then thankfully you showed us your frame and let the cat out of the bag. Cut the legs off square, drilled and taped two 2-56 mounting holes and boom, gears are no longer an issue

 

Driver's abdomen is the Vintage figure from the Fujimi kit, widened ~1/8" by sectioning in two .060 styrene strips. His arms and head are from the Monogram Chaparral re-issue. Cut off the helmet to reposition the visor and carved a little more here and there to resemble something from the 50's. I used Bryan Warmack's suggested method to improve the look of the goggles by digging out the eye sockets with a Dremel, painting some dots and filling the void with clear epoxy to simulate the lens.

 

Gary,

Thanks for the compliment and well wishes. Hope to see you and your new home track soon, still pondering and putting off the move back East.

[Jairus]

You mean Al Penrose at BWA.
Great info Bruce. 

Looks like the head of the driver is also Fujimi?

[Bruce Wayne]

Jairus,

 

Not sure of BWA's current ownership/status, but all of my dealings were with a chap named Andy. Either way ordering was smooth sailing and I highly recommend their products.

 

The driver's head/helmet started as the Monogram part, but was much modified to correct his visor (which pointed up too far), the full helmet was carved off at the bottom to better resemble the older open sided style, and a thin strip of stretched sprue was added for the goggle strap.

 

For pics I have some fantastic photos of it on track at BPR that Keith Tanaka took, but he sent them via e-mail to me in a compressed file, so I'll have those up as soon as I figure out how to un-zip them.
