The progression of my XR10 into a Berg.

Good eye! Yes, I plan on running the links in the general location of the upper of the two holes. One thing I did discover is that the hole placement on the stock tubes is in pretty much the worst spot for trying to run the shocks and links on the same bolt. It either needs to go in 5mm or out 5mm. I have two ideas on what I'm going to do about the shock/lower link mount, I'm either going to run one above the other or on the same bolt. It all depends on where the shock length falls relative to my targeted ride height.

I just slapped my XR together with the same info and locations others have used. I feel there is a lot of room for improvement on the XR SA and I'm taking a long time to develop each component and configuration because I want this car to be so dialed in that once its done there isn't a single wish or want for its capabilities. No worries about the wheelbase, it's about 3/8" long right now but it will be spot on when I finalize the layout. What you're looking at in these last pics is the equivalent accuracy of a sketch on a napkin. I'm hoping to make some good progress this weekend and if nothing else, work out the details on the axle placement and ride height.

I machined my axle bracket "L's" so the two sides are parallel to one another, is it possible that your bent screws were a result of simply clamping one ball end to a flat surface and the other to the angled surface and by tightening the screw down you also pulled the ball end up against the angled surface causing the screw to bend upon installation rather than impact?

The reason I ask is because I've been running aluminum bolts on all of my XR's control arm mounts and never bent one so far. The rear lowers and shock have shared a bolt since it was new.
 
That was a long day in the shop..... Only a few small details left to finish the rear up completely.

I'm not entirely positive I like the style of link/shock mount since it didnt end up as compact as I thought it would be. I guess I'll start on the other set tomorrow and see what one looks better on the car.

Certainly could be possible. I forget how that round can really ruin some of the mounting surface. I'm not sure its a big concern, just wanted to bring it up. These were black oxide steel bolts.

Nice work on the tubes so far man...clean machining.
 
The rear axle housing consisting of tubes, link mounts, case and upper link mounts is exactly 4.0 oz right now. I have a few ideas to save some more weight on it but we'll see how things go once I make some chips.
 
Its finally starting to look like something worth all (haha ya right! Just a small bit at the moment) of this work and money!

The revised mount is on the right. It still needs some to be weight removed and cleaning up...

However, the shocks bind up pretty bad even with spacers at the chassis so things could get tricky while trying to free up the range of motion and keep the chassis stable.
 
What rod ends are you using?

Also, it seems you are more than capable in the machine shop so why not angle the mounts slightly as well as get rid of the berg piece all together?
 
Bryce, I'm going to agree with Jeremy, your skills are far from lacking on this build.

I can't wait to see this truck running soon.
 
I was doing too much at once at work when I posted that. I meant to say that the revised design is on the left since I didn't like the fact that the mount was so far from the tube. Also, the berg piece is just a place holder at this point, if I adapt that design to work as I'd like it will get replaced with a machined 7075 U- shaped piece to offer double shear along with a small spacer for the shock mount to mount off the same bolt.

I played with it earlier today and managed to get the new link mount on and the shocks where I want them and there was no binding. So, I think I'm going to alter the design on the LEFT once more, remove a whole lot of material and have my final lower link mounts, they will be not unlike the ti-fighters lower mounts.

I may even have a few water jetted out so I can whip out a different mount when I swap the tubes up. These are just the initial trial run of what works and what I like. The rears weighed in at 1.4 oz for the pair. I'd like to get that down to at least 1.0 oz for both sides. These axles will be lighter, stronger and 10x more badass than any XR axle out there. I wouldn't e building them if I wasn't certain that these axles have a lot to offer.

So, I'm going to get some more machining done tomorrow (today) and with any stroke of luck, be able to bring an almost functional roller on Sunday.

Thanks!

To Comment on your statement, I'd like to see someone approach me to bring these to market, I don't have the desire to turn any more than a few tubes by hand so the likeliness of myself becoming a vendor, without at least the connections to get things CNC machined to my specifications, is roughly 1 in a million. I enjoy my day job too much to screw it up by making rc parts in the evenings.
 
It's nothing revolutionary but I have been talking with a few machine shops about making some of my designs. If I can get things in the range that I am thinking, I may be able to make these items (and possibly a whole axle worth of components) available to anyone who wants them. It's still very early but if I move forward with this I will be looking for a single retailer to be the outlet for this stuff. I am not looking to get rich, I'm not even really looking to make money at this, I just want to cover my costs and bring some of the cleanest, strongest and weight conscience berg parts to market in an attempt to bring the V1 Berg axles back to life. I have already established a business as Mazzola Motorsports llc. so that is what my parts will be labeled. One thing I will be absolutely focused on is quality and a timely availability of the end product. "thumbsup"

On the flip side, if I keep breaking parts like I have been, I'm going to walk away from this hobby and never look back.

I sure hope the figures I get back are realistic! :lmao:
