ESC plate made. New a-arm just shipped. Now on to the next item on the list. What are my options as far as getting custom dog bones made? I know Mike can make them, but he is so busy, and I don't know how long it would be until he has a chance to get to them. Are there any other company's that make them? Also I need to know how to measure them. Do I measure to the very ends of the groves in the cups or do I want a little room?

Pin to pin is usually the normal way of measuring, check if Kershawdesigns.com can help- Dan is usually good to deal with. You do want to leave about 1mm at either end of the dogbone/ pin to allow for chassis flex without the dogbones binding up or bending. Once the CD is mounted you can use calipers to check the distance between the drive cups + the depth of the slots for the dogbone pins.

Front drive shaft 83 mm (that is with the 1mm subtraction on each end), and the rear I will need a 131mm bone (minus 1 mm on each end). I found a 83mm Duratrax center dog bone, and a 131 Ofna center dog bone on Ebay both for under 20 dollars. They are on the way.

I'm not sure if that was luck or judgment, but those should work quite nicely

cmac · 07.27.2011, 09:16 AM

I assure you that it was all luck!!!!

I spoke to Dan at Kershaw Designs and he also has a set that will work so I bought them for only $23.00. I guess that they can be used for back-up.

Well, just got my replacement arm and it is perfect.I think I will try to redo my ESC plate. It is functional, but it's not my best work. I want it to be perfect so I will try again this weekend.

I received the dog bones, and the front shaft(83 mm) has a hair more than 2 mm of play. How much is reasonable?

That should be fine,you can put a Oring in each drive cup to take up the play or a slice of fuel tube it works to and then you are good to go??
Kept the good work going it would be looking like a truck now???

Not really yet. I'm still waiting for my new sheet of aluminum so I can make the ESC mounting plate (second try). The first one came out functional, but not perfect. I will try again. Does anyone know what size nut go on the end of the UE 6mm CVD's? My set did not come with the nuts.

WEB · 07.31.2011, 09:47 AM

Just use standard 6mm wheel nuts will fit the UE cvd"s,can you show us a pic off where you are up to,that would be great???

cmac · 07.31.2011, 02:57 PM

I'm planing on showing lots more pictures. I'm just waiting on more parts

I have fixed the slop in the front shaft with a piece of fuel tubing, and now have the perfect amount of play in the back shaft thanks to my father-in-law's bench grinder. Feels good to have a working drive-train!!!!!!!! As soon as I assemble the A-Arms and CVDs I will post pic's. Only problem I have right now is that I'm waiting on a set of hinge pins.

cmac · 08.02.2011, 07:05 AM

So what is everyone's opinion on Lunsford or UE"s Ti hinge pins?

Arct1k · 08.02.2011, 09:00 AM

I tried the lunsford ones on my crt.5 and found that they bent much easier than steel - I was very unimpressed.
