Wow, over a month since I last updated this thing!

First up a poll, What best describes your thoughts regarding this thread?

1. It's about time you updated it, I thought you forgot about this thread.
2. I forgot about this thread, you mean you're still working on it?
3. This thread's so old I've never seen it before.
4. Forget the poll, just finish the truck and show the pics!

Well, I couldn't actually add a poll so I'm going to assume that #4 is the winning answer! So let's say we finish this build?

Alright,last time I found the broken arm but didin't get it ordered for a while. I went on to assemble the bulk assembly up until I got to the missing control arm. Then I sarted to work on the main chassis assembly. I decided not to pull eveything off of it, just enough to clean off the rust and clean up the rest. But yet again I was met with another broken part. Turns out the engine mount was cracked. There were no signs of an impact on the mount or on the engine so I attribute the break to poor quality Chinese pot metal.

So now I need an arm and a mount. I was able to pick them up and a few other items from our own Motogod since he sold off his Warheads.

Mean while it's time to upgrade the slipper assembly. Here's a layout of the difference. The new version is a bit over engineered in my opinion. The good parts are that the plates have cooling fins formed on the backsides of them and they used a small roller thrust bearing under the tension spring.

One problem I found though, the back slipper plate has a ridge around the outer diameter to help retain the pad, but the pad is slightly bigger in diameter and pinched when assembled. It wouldn't do much slipping that way!

So I trimmed the pad and reassembled the the slipper. Now it's good to go.

Time to start some serious reassembly! First it's the mount then the engine, being carefull to set the spur mesh properly. The engine looks GOOD in there. :)

Then its on with the front and rear bulk/diff assemblies. Then the header and pipe followed by the fuel tank. I decided to add some color coordinated fuel lines since they were off anyway. So I cut and snaked them around and secured them to thier proper locations.
Time for an electronics test to make sure the servo linkages are set and adjusted properly.

With that done, Oh man it's getting close and looking good, IMO :D Now it's on with the two center skids. Mount the tires and wheels, wash and mount the body and WoooHooo!, The Warhead is DONE!

Well ok, no it's not done yet. Since I couldn't talk anyone into buying the 17mm hubs and the HPI Nubz I had for sale, I figure they need to be used. So let's put them on the this truck!
I quickly find a problem with this idea. The hubs are flat back and when tightening the retaining nut they lock up against the axle carriers. The pin holes line up ok so, a quick fix is in order. I simply put them in the lathe and skim cut the back leaving a small diameter to seat against the center on the carrier bearings. Problem one solved!

Now for the wheels. Well, if you can't tell from my builds,I like things to look as near new as possible or at least darn good. The wheels, as noted when listed, are scuffed up so something has to be done to make them look better. Another easy fix for me. Back to the lathe. I took a round piece of hard plastic and turned a diameter to match the size of the hole in the wheels. The I drilled/tapped a hole in the center for a retaining screw. This allowed me to mount the wheel to the spud(toolmakers technical name:hehe:) for turning.

The face of the wheel is not flat, so I had to indicate the cross-slide on the lathe to travel parallel with the face. Now I'm able to take a skim cut on the face of the wheel to clean up the scuffs. As is normal with molded plastic, the face was not completely uniform so I had to take a few light cuts until it cleaned up. Here's what it looked like after one cut.

Now with that done, the wheels look much better. So back home and on the truck they go. Yep, I'm happy with that. Now I'm calling it DONE! :celebrate3:

Sorry it took so long to get completed. Hopefully with all the pics this time I made it up to all of you. As soon as I get some good weather and time, I'll do a break-in and see how she drives. I'll be sure to post up my thoughts after driving it.

Anyone want to see me do another build? Well I've got one still to do. But first I have an update for the Cheap-O-Maxx and then the next thing I'm going to do I'm calling "The Savage Experiment : A Fish Out Of Water" .

As always, Happy Nitro Burnin!
What rpm do you run on the lathe for that cleanin up of the wheels?
