The "what you broke today" thread.

[Panko75]

A day or two ago, I removed a wheel from an old Tamiya and had the hex crack apart on me, don't you just love ABS plastic? Oh, and the diffs making noise.

I need to switch brands, heck even Redcats looking more appealing at this point.

Can’t even believe it.

Wow, twisted the toes right off of this one.

 

[WickedFog]

Pretty fragile looking wheel design.

 

[Tunedfrog]

Yeah it is.

 

[TeknoJ]

It’s a losi 22s wheel, that was 3S, on the front wheel. I ran the same wheels, tires, battery and motor/esc all the time on that same losi truck. This was the 2nd time I ran the Tekno on the street, and this wheel blew apart on a low speed turn!

Well, my computer is kind of acting up, and somebody mentioned a reset/reboot?

 

[TeknoJ]

That works for me everytime

Yeah, that's the 80's version of CTRL+ALT+DELETE

Hmm...let me see

Traxxas Stampede: Broke a kimbrough servo saver in a cart wheel incident.

Traxxas Emaxx: Broke rear body post, just snapped it by accident while moving it around.

WPL D12: Cracked the chassis just running around on the road outside, it cracked from a small "dip". This is the second D12 that I've broken this way too.

The kicker is that the repair for any one of these is roughly the same price, $8-$10. The waiting time on the other hand...

Traxxas Sledge.
1 rear carbon fiber shock tower. I saw this one coming and already had a M2C aluminum one in my junk bin waiting.
1 6s CNHL brick, cell 6 0.00v. I got it up to 3.2v but it won't hold. Dead!

The battery hurts, I didn't see that one coming.

Pin in my wheel adapter.
No clue how, just went away while driving. Never knew this could even happen.

The only way it can happen is if it falls out before you get the hex on, or if the wheel comes off.

Obviously not the only way . Drove around for half an hour, new drive shaft installed because there the pin was gone as well (due to feather holding it being broken). Installed everything, went driving.
So maybe pin had already issues before and i didn't notice it or it just couldn't handle 6S force, no clue.

If it's a lil loose centrifugal force can be a witch! Bandit did it once. Stampede was a habitual offender.

Glad you opted for the full reboot lol

I think I bwoke it

Shoulder screw for the rear shock backed out of shock tower. Traxxas designs aren't so efficient. I found a longer shoulder screw where it went through the other side and I could potentially put a nut on it, but I don't have any of those smaller 5.5mm nuts, and the shoulder part of that screw was too long for the shock cap part. Whatever. I just need to learn how to check over the car before my runs. Which 80 percent of the time I do, but that 20 percent is the times where I just wanna go out and run.

Not your average rc car wreck, but annoying just the same, a few weeks ago I broke a 3.0 mm HSS drill deep in the end of 3 1/4” aluminium bar stock whilst drilling out 6 bolt holes. Bit ambitious with the drill depth, now I have a nice lump of aluminium with a piece of HSS stuck deep in it and it ain’t coming out.

I hate waste. Where’s my hacksaw?

I went to work at a carbon fiber shop, where machining aluminum was like walking on the moon to the guys working there. I saw one of the uber smart engineers trying to dig a HSS drill bit out of an aluminum mold. It was buried in there about 5" deep. I told him he's never getting that out without an EDM to burn it out.

I asked him what his drill cycle was that he used, and what speed/feed. He said he just did a straight plunge, 30,000 RPM. I was like then then then

I told him "try a peck cycle, .200" per peck, at 2000 RPM, and about 5 IPM feed". I could tell by the look on his face my words didn't make sense to him.

The next day he had remade the mold and was trying desperately to dig yet another drill bit out that was buried even deeper. I asked how that happened, and if he had taken my advice. He said he tried 25,000 RPM

That will be happening as long as humans are on this planet.... companies want to hire 21 year olds and never hire 50 year olds with 30 years of experience.
