This is true.

Yea thats what I was thinking. Even if the carbonite threads a little bit rough you can Loctite a metal Helicoil in there, which will make it even stronger. There has to be some way to overcome this issue. Maybe some special process of heating it prior. If we can not come up with a contact for help there is one way to find out. I bet this guy making the parts has had some experience putting threads into some pieces? Either way I would like to give it a try on a few parts. If anyone else does make sure you share your experiences.

It's doable, I'm assuming a simple press fit threaded insert with some epoxy mixed in would be fine, however I would not want polycarb bulks as they would flex which would mess with the gear mesh inside the diff. Aluminum is the way to go for bulks imo.

Edit: Or you could easily just use a simple hex nut on the other side, but that can get sloppy if not done well.

I have worked with a lot of different materials in my career, and have even had to install a few poly carmonite windows into a security space that were 1/2" or thicker. Sure if you fabricate something that is only like 1/16" or 1/8" thick you are more than likely going to get some kind of flex. If you fab something that is 1/2" thick out of this stuff flex is likely to be pretty much elliminated. The mere design of the standard bulkhead has flex elliminating features built into it. SO making the same item out of poly corbonite would likely leave zero flex to deal with. At that thickness this stuff is almost like steel.

hmm threaded inserts sounds promising.

I love the idea of see through bulks.

A steel ring housing could be used for where the bearing would sit to offer a little more strength, if it is even necessary...

Yeah, a polycarbonate bulkhead would more than likely be sufficient for our applications if engineered correctly, and would probably look pretty damn cool, but I'd still go with some good ol' 7075 aluminum. To each his own however.

If anyone does do it I'd love to see it, haha. Would be pretty cool looking at diff gears spinning in there.

I agree that 7075-T6 is a good way to go for some of our parts. In fact I have one of only two sets made of GA Max bulks front & rear made of titanium. No I will not sell them either. I am one of the most stuborn hobbiests about using alloys to create that elusive bulletproof constructed R/C design, and most of my Maxx collection are designed in that direction. I build stuff that will outlast just about anthing else, and worrying about weight has never held a lot of fondness with me. Build it right, and install whatever powerplant required to make it move. Using a product like Poly carbonite in various parts would be unique and could create a very durable and yet notorious project for sure. So why not give it a try?

We have seen and or tried just about anything and everything known to man in this hobby and trying something new is always a challenge. I take what I can learn from other folks in here and use that in some of my projects, and I also do some things that others have not and/or will not try just to be different and go in a direction that is out of the norm. My father once told me that if you are not out there taking at lease some level of calculated risk in your life, then whats the point of living. I am very safety minded, but we also have to live a little and enjoy the free will of using every option in our toolbag.

GLADLY. Once our moving shipment arrives Mid May and we have a chance to get settled here at home I will gladly post up pics for you. I am trying right now to work out the details of my new R/C shop in our new garage. It was merely by chance when I was just getting started into this hobby and I was trying to order a pair of their GA aluminum 7075-T6 bulks when I received a phone call from GA asking if I would be interested in purchasing a full set of titanium bulks at the same price. He went on to explain to me that these were only one of two sets produced at the time. Of course I would never turn down any kind of one off creation that could do nothing but improve my build project. I would have to be a complete fool to say no. Even then I was not fully aware of what these things really were or what they would be worth then or now. I have had offers to purchase them from me, but I have no reason to sell them at this point. He told me that it was just something that they were toying around with to see if it would be worth putting into production. I guess they decided that it was not cost effective, because they never did. I would even be willing to bet looking back that he would have rather kept them instead of sell them in light of the present cost of titanium and the way this hobby has gone. Hind sight is 20/20, right?

Either way I know that I am a very lucky man and plan to hang on to them for a while. I had them on a UE Lightning SuperMaxx truck that I was going to do some high speed runs with(100+mph), but decided to go in a different direction with that truck. In light of the rareity if some of my stuff now I do not want to chance destroying any of my truly valuable R/C gear. Just like so many others I am betting that some of it will become even more valuable down the road. Anyway they are still in brand new mint condition without a scratch on them. If I do use them it will more than likely be in a shelfqueen piece of artwork that will never be run outside of my house. Rare objects like that should be protected much like that of a rare stone or precious piece of family jewelry. The only way the set will leave my collection is if I decided to get out of the R/C hobby altogether or my wife sells them after my death. I may foget about your request, so ask me about the pics after we get our stuff in May. They are mounted on the truck in these pictures. It is a UE Lightning with double monoblock and custom Rcalloys rear driveshaft.

I like the idea of building a nearly complete vehicle from that stuff. One could call it the invisible car/truck. Or maybe just pretend that it is a copy of Wonder Woman's super hero vehicle, much like the invisible plane she used in her series.

Here you go Jerry. I made a Rustler out of lexan way back ago. Had the chassis, arms and towers. Ran if for almost a year.

It look like he does nice work. Polycarb works great for making parts. I've never had any problems using threading a hole in it. I just drilled a hole slightly smaller then the screw and then work the screw in and out of it until it reached the full depth. You let the screw do the threading and try not to get it too hot other wise the threading will not be as good. Hold a screw tighter then the stock plastic parts if done that way. I have used the insert on a couple of occasions when the whole was offset or drilled to large.

I thought seeing through the lexan was also great so I made a Gee1 transmissoin plate out it for my old emaxx. Thought it added a cool touch to the emaxx.

Here's the thread with some pics of it.

Tough stuff guys.

[JERRY2KONE]

Hey Guy good to see you still hanging around in here. I remember your lit up tranny project. That was pretty cool. Where there is a will, there is a way. Too bad you couldn't use one of those 3D printers and make stuff from poly carbonite that way. Just think, you could lay in a stock TRX bulkhead and out would come a fully bulletproof replacement in just minutes.
