Hey it's me again, Got an update on the two pcs shocks, THEY WORK! Anyway I went thought about 8 different internal tube designs and bench tested them as best I could. Ended up with a shock that works really well. So I'm onto making four total mounting them on a rig and hitting the rocks. But right now they cycle fully are easily bleed, super smooth with no hard spots/dead spots in them. 1st test is going to be with 50wt shock oil, then 70wt dif oil. Still working on the over all weight, I'd like them to be 10grams total. May need a tester or two lol. [/URL] [/URL] [/URL] Thanks for looking! Last edited by ROCKCRUISER; 06-21-2016 at 06:58 PM.

So I've been working on getting all my parts as light as possible. Here's some of the reworked parts." Front beadlock inner rings for internal weight system. My first design weighed in at 14 grams. [/URL] Rear beadlock inner ring or both with no internal weight just beadlock. [/URL] Smaller OD front inner ring for internal weight system, allowing for more foam tuning. [/URL] New Bully 2 Hub with a 14mm pin instead of 10. The old hub weighed in at 18grams. This new hub get me at 10 3/4 before mounting tires on my rims. [/URL] |

| Re: RC's Bully2 / SuDu 3D Build Wouldn't the arm (being bend inward) stuff the ackeman of the steering geometry?

Just cut some sweet CF rings, straight from the mind of Mr. Crawlinghulls. This is his set to go with those nice beadlocks. [/URL] [/URL] [/URL] |

Update with more parts I just made, hot off the press. Some Grade 5 Ti or 6AL-4V Titanium [/URL] [/URL] [/URL] Setting up lol [/URL] Saved about 13 grams just in the rear shafts, still think I could lighten them a little more.

Nice work on the rig so far. Looks like a lot of fun. What is the OD of the largest part of your weight system? I tried 4 3/8" with delrin. Wanted to try CF and never got to it. The ackerman thing is going to be weird. Outside wheel is going to turn sharper than the inside. If it ends up being a problem flip them over and run a longer rod. Very nice work on the carbon fiber parts! Good to see someone making their own parts.

3 1/2 is the biggest then 3 3/8 and a 3 1/4 for a friend to try. 1st size I'm going to give a try is 3 1/2 leaves just enough room for foam, maybe. Still working on the weight holder, did a redesign on this week need to cut a few new ones. Changed the way the weight is mounted more options. As for the steering arms have to wait until the rigs up and running so I can get some testing in. Then changes will happen or I'll make a whole new knuckle lol. Thanks again | |

| Re: RC's Bully2 / SuDu 3D Build Sorry that pic was just for show, there's a new shot! I didn't get to fancy with the hole locations just did it by hand. I'm probably going to make Delrin axle tubes cut in half to go with the CF tubes. All the work will be done on my CNC 7 axis lathe. So hole locations will be the same on all sets. 3M does make a really good adhesives for CF to metal. I'll give it a try later on but for right now I'm going to run the 3mm screws. [/URL] |
