Here you go, A.

The weights are close to final. The shafts and the UJs will be shorter when fitted, but this should give you a clue what you've gotten into here.

I think these things are worth every gram.

That adds a bit of weight to it. This should be good as this should help make the rig plant better since it's all axle weight. I can't wait to test these bad boys!!!

I think I finaly fully understand how this works. Correct me if I'm wrong, but you will be boring out the thick end of the blank then you insert the UJ end it it and brase or CA or set it so that they both become one. This way if you break and axle, I just buy another set of UJ's and cut it to length again!... I like the way you think.

Do you think dripping an tapping holes for 2 - 3 MM set screws would work with out killing the shafts integrity. Heck, if I even did one 3mm set screw, cut a notch in the UJ chaft for it to seat in and used blue lock tight on the axle parts, I don't think it would go anywhere. I had the ser screw hole on one of my 10T Pinions strip on me so just lock tighted it in place and it hasn't slipped yet. Then If I have to take it off, all I have to do take a lighter to is and heat it up and they pull apart with a little bit of force. What do you think?

My last thought is that the knuckled look stout enough that i'll be able to cut them down and do a zero ackerman mod on them to be able to get the max stearing out of these UJ's!

You got it. "thumbsup"

M has planned to use set screws all along, until he trusts the joints.

The 25mm socket depth is my gut level dimension for CA. I'll try it if you guys don't rule it out.

M's blanks are cut. They look better than yours... Tess' (the old girl) will look even better... and mine should be absolutely stunning! All of which means nothing to function, and none of which will be visible.

I ran these so fast that they stayed hot to the touch, and had to cool before the bearings would fit.

Next is a fixture to cut the flats quickly and accurately. With some luck, I'll get this done before the tiny center drills show up, and I can sink the sockets.

A, I think you'll like these knuckles enough to show you why I'm not in a big hurry to go custom.

I think you have the exact idea to make this work. This also leaves open the ability to try diferent cvds and such if these don't hold out. I wonder, would there be enough room to put a traxxas uj for the center axles like on most shaftys.
Then you could spin off a small 5mm step to 8mm stub. Then the only failure you would get would be that uj hummm I might have to try that.

As to set screws: As far as reducing the strength of the collars by drilling holes... I will cheerfully honor the permanent replacement guarantee under these conditions:

As long as 2 or more of the holes are never an equal distance from either end, and they come no closer to each other, or the collar's ends, than 5mm... go for it. Drill all you want... we went to a lot of trouble to keep thick walls, and this is why I feel good about that choice.

I'd like to see the following: First, (1) 3mm centered in the length of the collar. If that fails, or even shows tendencies to loosen, rotate 180* and set (2) 2mm. If that fails, go 90*, and set (2) 3mm... etc.

Based on my experience, I'm betting the 2mm, with the holes carefully tapped (to remain tightly nested), will be the end of the experiment. Use blue.

We are now open to an amazing array of joint choices... with the room we now have, we can try anything.

We can use the 300s now, so the hunt will be for cost effective alternatives... we already know that if the budget allows, we are at 50.5*. These UJ will either be a good choice, or the best cannon fodder for our early experiments. Win/win so far.

Anyone have stock tires and wheels they can let go cheaply?

 

[BentMetaL]

Tires and wheels!!

I've got the full set barely ran. If you interested let me know.

 

[ekd]

Thanks, Don. PM me a price?

Anyone else? I need more...

Sound good to me, you're the boss. I like your idea of using 2mm set screws, i didn't even think of that. I'll start with one set screw and the blue if the 2mm fails I always have the option of upping it to 3mm set screw. Though, I'll probly just stick with one set screw as more than that wouldn't brobly make a diference. I mean the pinions on the motors only use 1 set screw. I can get them drilled in my drill press and then tap them with my hand tap, shouldn't be hard.

I really hope these U's won't explode because it will be so nice to have an inexpensive upgrade for this setup. if not We shal continue trying options.

Me too. Even if they aren't up to extreme angles, I'm hoping they give us a good solid upgrade for the money. You just can't beat the price.

Almost got all the blanks cut. Conditions permitting, I'll have them done by sunrise. I plug away, when I can... :mrgreen:. Still on schedule here!

Guys, I could use some help here.

I have begun to collect parts for my sweetheart's crawler. It will be a 2.2 Mad. Here's why: M sent me a set of tires and wheels that are too nice for savages like me, and A is gonna send a Rock Hawk kit (the look is growing on me, quickly... T will LOVE it). She'll never comp it, but I don't want it to let her down if she gets good at this.

This isn't an Xmas present, so there is plenty of time to do it right.

What I need is advice and ideas... as well as parts from your leftovers piles. If you have something it needs, pls PM me with a price (or a trade if you need something fabbed).

The dimensions are up to us. No rules. I just need to build something that will be durable and competent enough to build skills with, and bring out the smiles.

TIA

Reply sent. Thanks, man.

We're gonna have some fun with this. As soon as you guys are supplied, it's her turn. The weird S can wait.

 

[ekd]

Faced and center drilled.

Faced and center drilled.

Purty, I'm so excited. Totaly can't wait.

 

[ekd]

It's been a long time since I have been as anxious to ship as I am right now. :mrgreen: Can't wait to see these run.

The DRO will let me put flats on equivalent to the tolerances I've held so far. The center drills are tiny (#1), and the last real danger of ruining these passed when I didn't snap a tip in one of these holes. I went very slowly.

I'll bore them, and then dress them by hand, soon. Then flats when the DRO shows... Ship... and I'm done.

After a couple deep breaths... Mad 2.2.

It's fun knowing you guys! "thumbsup"

Awesome work guys. I have a MS 8 and a MT for my son and I to open for x-mas. We do need a section for these !!

Welcome to the Asylum!

I gotta ask... which one will you be getting?

 

[DSC]

I picked up a used Max Stone 8 for a good price and I bought a new Mad Torque. Putting them both under the tree and let my son pick the one he wants. We don't have any rock crawling courses around here so it will be him and I playing in the yard and in the house messing around. I messed with the Max Stone for a little bit and seemed well worth the money for what we will be doing.

That's nice work your doing. I have a lathe at my house, the best thing you can have. I make up things to make just to use it.

 

[ekd]

Thanks!

Yeah, the things are indispensable... and I should have gotten mine a long time ago. I have been saving parts for a lot of odd projects, and now I'm getting ideas right and left.

Sounds like you two will have a ton of fun together. These really are a good starting point for exploring crawling at a decent price.

If you happen to get a pic of the 2 together, please post it here? I'd like a visual comparison... the Max looks huge. If it isn't wrapped yet, I'd also appreciate knowing the wheel and tire ODs? Thx.

Planning any mods to these?

 

[DSC]

Will do on the pics. The Mad Torque has not made it in yet.

Mods...Of course...Thats what us guys are supposed to do right...:mrgreen:.. Thats what i told my son,, mods mods and more mods...he's 5. I'll see what one he takes to the most and I'll start messing with the other.

I would to see how your FPV turns out. I've been looking at that for some time.
