If you want to make it an anglewinder I made some mounting plates for EBD chassis'.  Yours for the asking.

Hi Pablo,

I can let you have a set of these Russkit wire wheel inserts with a bit different style of knockoff:

Is that motor plate a commercial piece or is it custom made by Don?

I do read each & every post in a thread with the [View New Content] button. Only editing an existing post would escape it.  This is a case that post #2 didn't contain a photo, so I probably gave it less attention than I would have given a photo. Photos say a thousand words & internet photos last infinitely (as far as we can tell.).

The chassis will be based on the January 1969 Car Model magazine article, "How to build the latest Super Bat Pan plumber chassis" by Team Nutley Captain, Mike Tango.

Built by Tony P.  :D The original used a 16D motor, but I think I can make this 26D work fine.

 

dc-65x built a similar chassis configured for left hand EB drive in 2006. I'll be utilizing his work as a reference also (I'd be a fool not to :) ):

 

http://slotblog.net/...58-26d-pro-car/

 

Plus, I built one of these myself (with a 16D) in 2013. Luckily, it's still in my possession :dance3:

Wheel inserts: I tried really hard to find .500" OD Borrani wire wheel inserts of this type and they are simply not commercially available.

Today I ordered a set of Professor Motor inserts that may work:

 

http://www.professor...-p/pmtr5029.htm

 

Capt. Rick, if the above inserts don't work for me, I'll take you up on your kind offer in post # 6 :)

I never want to use rare parts unless they are absolutely a "must have" - this car doesn't absolutely "have to have" inserts by any means.

But wire spokes would look nice :)

Anyone  cloning the Russkit insets in resin?  The BWA inserts disappeared a couple years back, but is anyone else working in some back room?

I don't think there is a problem using the Russkit inserts Pablo. I can give you a set that are not a mint collector's item. The chrome has faded on them and they'll need to be restored by painting.

Thanks for the link, Chris. :good: But I see the only sizes are .375, .450, and .540

 

Between Rick's and the Professor Motor's on the way, I should be all right.

Drop arm trimmed, trued, flattened, and flag hole tilt checked.

This one was obviously designed for a Cox, so I installed a pair of .032 brass rod stops

 

IMG_3080.JPG

 

Outer rails .063" wire; inner .063" rod, middle not shown yet but will also be .063" rod.

Similar to dc-65x's chassis in that respect.

 

IMG_3077.JPG

 

My rail setup may seem strange due to my 26D motor box being smaller than most.

But I thought it over and that's what I came up with  :)

Thanks Don :)

 

Front end is just like Tony's but the outer wire rail is further out to accommodate my 26D motor box:

 

IMG_3087.JPG

 

To harness the torque and mass of the 26D I took liberty to add an additional brace to Don's bracket:

Drop arm stop is .032" vice .063" rod. Plumber rails pretty much the same way Tony did his, except for minor variations in wire sizes.
