Parts gathering and planning begins. Motor starts with a new in bag American Line Hemi, marked "JAPAN" and "HEMI" on the endbell. Obviously intended to be either a can drive or an endbell drive powerplant. Windings are blue but that will soon change.....

The REHCO "Dubro" motor brackets also fit the small Hemi when needed.

 

That body, when Jairus used it in the Choti Proxy was labeled "Guthwine." Ray Price called it "Manta Ray."  I'm thinking it might have been a Ray Fellows creation, but I'm not sure.

Gúthwinë was the sword of Éomer from Lord of the Rings.  That's the name I gave the car. But Choti's were never named and only numbered.
Here is the artwork from that race with the correct numbers for the bodies that I knew of.

So, should I call it a "Choti #15", or an "O2R" ?

 

Motor is going to be thoroughly blueprinted and rewound by Havlicek, can drive with ball bearing, shimmed modern "C" race magnets zapped and matched by Cheater  :dance3:  :aggressive:

What you call the body is immaterial at this point. Name it once it's painted & the car is complete.  :good:

Good idea. I really like the way the cockpit bubbles up to allow motor clearance in just the right spot  :)

Digging through some of those old files I found this advertisement.  This I guess are the names John Chota gave them. 
#15 came with and with-out the exhaust pipes.  Or maybe that was a Ray Fellows addition?  At any rate, contact Ray (O2R) if you want one.

Thanks Kim, the HEMI was gifted to me from dc-65x  :D  Just wait until John Havlicek gets a hold of it :whistle3:

 

Modifying a U-Go bracket is tricky. I studied the way Capt. Rick did it starting with post #44 here:

 

http://slotblog.net/...thingies/page-2

 

Rick had to sacrifice an extra bracket to do it so SANO, but I don't have that luxury. My plan is to install (Slick 7) bushings on the sides with silver solder before attaching them to the bracket face

Just a comment: I'd use the silver solder to assemble the pieces of the bracket itself, & 60:40 or 63:37 to solder in the bushings. I've not seen a situation where bushings required the extra strength of silver solder. Your experience many be different, but remember I'm a person who sometimes built chassis using 100% silver solder. Build on. :)

Bill, I plan to use silver solder to attach the sides to the face also.

For me it's not a strength issue, it's a technique to keep certain solder joints from melting when I don't want them to.

That way, once I start attaching rails, braces, etc. with 60/40 the key components won't come undone  :)

More planning - WB 4 1/8", GL 1 1/8", chassis width 3 1/8", wheel width front 2 15/16", rear 3 1/4".

Front wheels will be O-rings; rears will be orange donuts trimmed to about .765" OD.

 

Here is how I'm going to start the process of re-attaching the motor bracket sides to the face.

I call it a "process" because at first it's not going to meet the standards of the micro-managers.

For now, I'm just tacking it together using my Hakko 455 and silver solder. 

As it progresses it will get stronger, trust me.

 

All trussed up in perfect alignment; the face is exactly 17/32 forward of the axle center

Is the bracket plated steel or plated brass? I've never had any U-GO Smith parts to work with. Final soldering of the sides looks like it could be a job for el-torch. :)

The U-Go solders easy but corrodes instantly with acid flux. Later on I'll polish it off. 

Twin .032 "L" brace wires space the indentation out, strengthen the connection, and allow solder to pool

Anyone know why these U-GO Smith motor brackets were made with such a large distance from the motor mount face to the axle center line? Were they made for using with large rear tires & crown gears on SFB area thingies? Any hypoid built in? I've never had my hands on any of these brackets..

The long distance makes no sense to me because the axle holes are set at a height giving 1/16 clearance with .750 wheels.

Meaning a .686 OD crown would give 1/32 clearance - anything larger wouldn't be legal.

 

They are non-hypoid.

 

I got away using a super long shaft and pinion on my previous build without shortening it, but I wouldn't want to do it again.

A long shaft acts like a nice lever to wear the bushing prematurely.

Ten .032 wire braces and an .047 "gear guard" brace should be enough for now  :D  :aggressive:

My Hemi has been Havlicek'd to the max - dual BB's, 29 wire, modern "C" matched race magnets, arm balanced and ground to specs, can mounting holes tapped 2-56 and reinforced with backing plates, etc. Now it's "game on"

Bracket positioned in the jig; bottom edges of tongue faced flat and flag rotating area tilted slightly up to allow for a .063/032 clearance slope
