:) Mike the rules look good and seem to cover the basics but the part about the axle tube bracing being allowed to be visible makes sense but then it says axle uprights must not be visible from above. This sounds contradictory to me--aren't the bracing and the uprights the same thing?

I think what Mike means is looking from above you can't see upright outside the body shell.

F & R maximum track width- 3.125"


Presumably, this is intended to be the maximum overall width, and not the track width?

Track width is measured from centerline of one wheel to centerline of the opposite wheel.

Thanks for pointing that out .

 

Must be a common slot car mistake.

 

A few different slot car org. use that term on their "Simplified Specification Reference".

Sure.

If want your car to be undrivable. 

 

Those front tires are awfully hard.

No the uprights are what axle is attached to, and are vertical, whether it be a bent up piece of brass or piano wire.

 

Bracing would be horizontal.

 

As the last line of that paragraph states, it 's to prevent A arm style front ends.

 

IOW, the attachment points of the axle or axle tubes, to the chassis,  must originate from inside the body.

Everything but the minor parts such as lead wire, lead wire clips, braid, guide nuts, guide washers, and axle spacers.

Is using a cut down guide shoe advisable with so much front clearance? Even if the guide tongue is

soldered to the bottom of the front piece, it has to clear the .050 track height. That means to use a

cut down shoe, you have to stack up a lot of washers.

Good point.

 

I'll switch to the non cut-down in the kit.

I assume you mean the front.

 

Yes, the BRP style, 3/32" front axle with threads, and locknuts on the end, can be used.

I ordered more bodies yesterday from the guy pulling them.

I'll have to see if Dave Crevie will cast more of the resin parts.
