Big hands and feet! Lol!!! No mr nutters is busy wrenching elsewhere

Let's have a competition..... Guess the weight of rear axle and tires mounted when completed.
I say.... 27lbs. ish.

[Bo Wallen]

Yea.
I say 27.7 lbs. ish.

Daahmm Mario!! I put stuff on scale and tried to figure it out!!! I guess the camera doesn't add a few pounds after all!!

This just in Mr. Nutters has fallen on hard times and will do anything for food

Would like to add to the 2-motors-1-axle discussion, but I cannot find the reference. It was posted by one of our European friends (I think on this forum) explaining that if the two motors are on opposite ends of the same axle, they should be wired in series, and when under load, the motors will create an "electrical differential" by splitting the power proportionally, based on individual motor load and RPM. If using multiple axles with 2 motors each, series wiring on each axle and parallel wiring from axle to axle.

Perhaps someone else read this or the author of the post may see this, so we can find the original discussion.

How do you get so close to a squirrel to catch them as pets . I've touched one and it took of like a rocket ! Mike

Haha!! I wish I had your luck!!! Naaaa,, we have "acquired" a few odd pets from other people thinking I like them. Save one and the whole town thinks I'm open to saving all!! I was given mr nutters from a little girl and mom, found on ground. I couldn't say no, so we nursed him back and then released him In plenty of time for the upcoming small game season. . We pre stuffed him!!! Bulked him up for a good mount!! Hahaha, (let him go in a campground)
YOU REALLY DONT WANT ONE FOR A PET!! The bite through hard nuts- fingers are very soft!!

So the tires/axle???? I'm slightly at an advantage here but I'll play,,, I'm saying 28.8

Got some idea of what rim I'm doing. The size of these parts has made me think of using separate pieces combining into one. That requires me to learn how to weld alum. No spool gun . No tig, just the long line gun on the mig. . But I did pick up a tank of argon. Luckily none of the welds will be visible and I'm going to be turning/milling them down. So what could go wrong!!! Lol!!! Thinking I really only need to to about 10" of alum weld all together. I still can't justify a tig welder,,,,,yet!!! Might change when I start pulling birdsnests out of the line feed!!!

[jasonthekid]

Those sure are some pretty tires! Can't wait to see them dirty! Like the rest of your machines I'm sure this one will be top notch

[Cooper]

Thanks Jason, I'm pretty eager to get them rolling with some battery power!!! Got the four back wheels partially made.

[RCP57]

Pretty! What parts are you welding?

[Cooper]

I've been trying to purchase correct dimensional stock alum so I don't have to cut much off. Instead of turning a 4" piece I got 4"X11/2" wall tube. And then turning thin sections for the hub. Welding that to the rim.


I did do a few experimental welds to check penetration and learn how to. It's thick for my Hobart handler 140. I did try to hammer parts apart and held well. And the turning on the lathe didn't dislodge it so I think I'm safe.


And my "hands on" design of how clearances will play,,,





Again no paper design just what's left of my brain and in hand parts!!



I'll be cutting the colored areas once I figure out how to set it up

[Cooper]

And yes design flaw in this part for number of holes . Missread on the dro

So each tire has a two piece rim that bolted together to squeeze the bead for a positive lock?

Yes , the two pieces of rim will be bolted to the axle hub. Basically sandwiching the axle hub. And if for some reason if I do have any tire slippage, I have enough material that I could remove more. I also have the rim offset a bit. I will be really surprised if I do have slippage on the rim as they are pretty snugg

Hey Cooper.....looking forward to seeing this build !!! Be nice to see another big haul truck on here , considering our trucks are different in scale yours being a bigger truck 1:1 scale they will almost be the same size as models!!
You will be pleased with the power of the banebot motor/gear box , very strong!!! The power they put out is almost a bit scary...lol...just remember there is only one ball bearing supporting the 1/2" output shaft, try not to put to much axial load on it, they recommend limiting the torque to only 35 ft lbs but with the big tires and no other reduction you may need it all.(You still might need more reduction to bring the speed down and the torque up, at 70-90 RPM that thing will haul a$$ )

What size are the tires? What motor did you get on the gear box ??

Really like the tires you made!!! Looking great!!( Hey, buddy, pal ,I could use a set...LOL)

Keep up the nice work!!!

[Cooper]

Hey dads, thanks!! 1) nice to see the one video of you loading, one 5gallon bucket, and another scoop!!! Really puts perspective on how much material is in the dump body!! 2) water jet!?!!! You are so lucky!!! I need to go over to next town, a guy that has a food automation processing line company specializes in water cutting,, I really should go see him as he is a big fan of scale planes. Right next to his facility he has a manicured 100+yard runway. Figure similar RC interests I might get some cheep cutting done. 3) I have the two drive motors of 256:1 gear reduction. Don't know what motor is on the end, but noisy little buggers at 12v!!! Might not need any sound system!! I'm thinking that having two for drive will be enough torque and power. And yes I'm trying to take all weight off motor shafts and put on axles. With not wanting to spent $100-200 on a single slim profile bearing (needing 4) I am trying to incorporate 2" bearings for wheel hub carrier. I'm planing on having the two motors in axle, hopefully use some radio programming for a differential effect when wheel turned to left/right max. And some good info on your build, I would never have thought about proper geometry on Ackerman effect if you would have not posted about it!! Tires? I really wanted to use the same ones you got and not have to go through the whole process of making them. If I remember correct they were just a little too off on dimensions for my project. Spent a lot of time trying to find tires, just couldn't find close enough size. Might be able to work something up for you in future!! Still need to see how they preform in actual use.
