OK, I normally don't build thingies but Jairus's T-shirt just looked too COOL to resist.

First off, none of this buld would be possible if it weren't for the help of Pablo, Horsepower, and my friend Bill Worden, who is using his machinist skills to make some parts for the build.

Here are some of the parts.

More to follow...

[Jairus]

Looks promising, Rob. I like the choice of motor, and I just might have to get back to my build one of these days!

[Mopar Rob]

It might need to drop a hotter arm in it? Not sure how hot I can go without melting the endbell?

[Jairus]

This is not your normal race, Rob. A faster/hotter motor might be great in a 45 minute sprint... but will be burned out after a couple races in the proxy. Think "longevity"! Zapping the magnets, soldering the brush tubes, and balancing the arm are the only things you will need to keep the car shiny side up.

You don't want speed but laps and easy to drive. From experience, a solid 26D wind is an excellent choice in the beginning, so do what is needed to make the motor bulletproof!

Edit: However, if you really want a "rewind"... try this!

[Mopar Rob]

More parts thanks to Pablo.

[MantaRay]

Help... I need a motor bracket like the one Rob has... a 26D solid inline.

[Mopar Rob]

Ray:

You also going to enter a car? If you need me to paint whatever thingie body you decide on, let me know.

[JohnnySlotcar]

Me, too! I may run a Pittman 6001X ball bearing motor!!!

[Mopar Rob]

Wow, that would be three cars from Chicago.

[JohnnySlotcar]

It will either be that or an original Dynamic car I ran in 1967 and won a two-hour enduro with a Champion 507 with independent Dynamic front suspension; just had Ricky D rebuild the motor! Look out for these, as I actually raced them.

[Mopar Rob]

Yeah, but I have Bill Worden making some trick parts for me using some outside-the-box thinking

We can test before the Proxy at the Field house and Swiss's.

[Jairus]

Hey, Rob, you going to go and try to match this?

It's called a "proxy" race, not a "Let's the car dialed in on one of the tracks that it'll run on" race.

[Jairus]

All true, Mike!

But, it takes testing to make sure the car can turn laps without heating up, burning out, or eating gears.

[MSwiss]

I'm goofing with Rob. I'm sure he'll find a track to test it on.

If we're running the Proxy race on the King, I'll let him try it on the flat track.

[Jairus]

Good idea, Mike. Most of the tracks will end up being short anyway with a couple of plastic European tracks tossed in just to make it interesting. If the car can be driven by anyone on the flat track then... it should be a... CONTENDER!

(I'd better get working on my car then! *gasp*)

[MSwiss]

If you don't rein Rob in, he'll be at every track testing, spouting some nonsense like "I can test there and then get a good pulled pork sandwich a half hour down the street at Joe Kapoofnik's.

"I can drive 17 hours to test my Dynamic car, but I can't make it the Saturday night races at Chicagoland".

[Mopar Rob]

Hey, Rob, you going to go and try to match this?

No, it's going to be my usual race colors of copper with a candy red stripe with black lace. I'm thinking of having a candy red or yellow windshield?

Nice arm and Arco mags are also available but has anyone seen bulletproof 26D endbells?

I haven't.

Hi,

There was a Simco/Associated endbell for the 26D that was heat resistant and used Pittman overhead brushes, but it didn't really work. Back then what we did was use the Pittman 6001BB endbell. That thing was unkillable, but NOS cost more than the 26D we used it on!

Me, too! I may run a Pittman 6001X ball bearing motor!!!

Hi John,

I'm currently working on my entry which is also a BB Pittcan. As you know, they have an .093" shaft.

I was worried about the pinion gears available, seems like a 9 tooth is about the smallest practical gear and I could only find them in brass. I wouldn't trust a brass gear to last the whole series.

My solution was to totally readjust my Hudy comm lathe and turn the shaft down to .0785". Now I can use my favorite inline pinion, an angled ARP 8 tooth, to get a low enough gear ratio for the European tracks. I figure on using an 8/30 or 8/31 gearset.

Food for thought! This may also be helpful for anyone using a big ol' 36D.

Here's a shot of the motor with the gear slid on before soldering.

[kgalasso]

Pretty cool!

[Mopar Rob]

It's called a "proxy" race, not a "Let's the car dialed in on one of the tracks that it'll run on" race.

Well, since we have all sorts of thread drift I thought I'd post pictures of the F1 I built while waiting on my parts. I just am showing pictures of the finished product since it's a duplicate of the one that I made for the Sano Dave raffle. If someone wants to see the build, go HERE.

Since Swiss won't let me test my Dynamic Proxy entry on his King (or ONE as it's called), than I probably shouldn't point out that that I used his Backagra and coined tongue for this build? Don't worry, Swiss knows I'm just kidding

[Mopar Rob]

I took some degraded photos today from the ultra-secret SCM Thingie Lab. I'll work on some better photos after I finish my Deuce-Agra build.

Lots of tuning features will be built in so when I make my 7-1/2 hour drive to test on the Rt. 93 American King, I'll be able to leave with it perfect for the Proxy

[68Caddy]

Rob, that looks way cool and I think having Pablo and Jairus there as observers, you can't go wrong.
More pics when it happens.

BTW I got my ride back that I destroyed at Checkpoint... thanks for fixing it for me. (You know who.) Now it's way strong and I'm ready for another run.
