Sting's drum

I took a few photos of the carnage:

not quite Fluffy on fire, but it was a pretty good show....

You might be able to see where the problem is/was.....I cut off the drum too close to the outmost dowel pin hole, so the wall thickness at that location was very thin...that is where the crack started.

Then, after the drum cracked, I drilled and tapped to try and squeeze the crack closed. That didn't work and actually made things worse. The 7075 was stressed and the crack blew open before I could reach cake....lol the plan was to try to eject him again, with the other end of the drum....hahaha

I do have a pretty stout alternative tho.....

on a side note, inthe fight against the plastic wedge, Sting ended up on its side, and I forgot to install the rollover screws. I thought that just spinning the drum would cause the bot to vibrate and eventualy flip back down.....no such luck....the drum was too well balanced and the bot wouldn't budge even at over 25k rpm's

In that I spilled the beans on the rfl forum.....

Here's the latest S7 drum that sting will attempt to destroy

OOOOOOOO
Pulley?

Ya, it's kinda hard to top Fluffy! I really need to make one of these 3 pounders!

I see what you're saying about the crack, and I agree. the new one looks interesting..

wedge ha
im suprised you havent
RJW and Jamo have really stepped up the class, both topping genes bots
and there both so close to you!

mini fluffy? lol itty bitty flames

Belt rides between the 2 inner blades...maybe a slight recess or lifted surface...depending on weight and ratio

If this one doesn't work then I'm gonna challenge fluffy to a dual to the death....maybe burn sting into charcoal...lol

that'd be fun!

Gene's bots keep coming...one hit between Jamo and sting and both bots were reduced to pushers

Plus ther's no ejection area at Moto...so it could get ugly.

I'm sure that jamo will get his stuff together...it was Cake's maiden voyage

Sting on the on the hand has a bad habit of ejecting or tashing bots while self-destructing itself...

there will be total carnage at Moto...If the plastic and alu bots can trash Sting , SOT and the 12 pound clones, then I tip my hat to them...otherwise , we might all be in for the long haul and the plastic and chewy aluminum could be flowing in the streets.....

I won't be driving any of the drums....tha twould be too easy.

I will smash the Ti wedges into everything in the place as hard as I can as fast as I can and as much as I can. a Lot of full body spinner emulation...or whatever. If I can just hit something plastic or alu at full speed...we'll hopefully see why Ti costs more than alu and UHMD

Or I'll just blow up, catch fire and bury them next to Fluffy

we didn't bury it!

It wasn't meant to be taken literally......but a big Fluffy comeback would be like rising from the almost dead..no???f

Did you at least clean the nasty green stuff off of poor Fluffy?

fluffy did not look like a happy camper at the Starbots shindig....

In retrospect, I like how jamo's drum got a very good bite on wallop, so here's V2... the hammer is back!!

does a curved tooth have any perfomance difference against a wedge compared to a flat tooth?
Do you see any cons to have a curved tooth over a flat tooth?

It seems like common sense and it also seemed evident in practice, that a sharper edge will bite more

A square tooth has a 90 degree angle , while Jamo's is more acute.....I haven't measured what the actual rough angle is on his drum, but I suppose that I could, mind your it's a flat front edge and curved trailing edge, but we should be able to get a ballpark figure.

On the downside, the more acute tooth will chip and/or break easier...the square tooth is blunt and strong.

However, at GCRS, Jamo's drum kept biting away at other bots, even when he wasn't really under them...or so it seemed.

To launch bots and for longevity, the squarish tooth is the way to go, but to get a bettter bite...I vote more acute. you need to get under them to launch them anyhow....just bring more blades or drums, cause they are going to wear more quickly.

Make sense?

Learned a little lol
I figured alot of that but was just getting your oppinion, maybe you saw something i missed

many years ago, I was hired by an architectural woodworking firm to solve a problem with hardwood handrails. The wood was chipping badly when fed thru a 5 spindle moulder.

the machine manufacturer was trying to sell them $250k worth of new cutterheads with a hardwood angle built in...the existing heads were all 20 degrees or more and while great for softwoods, they weren't so good for rock maple...lol

I solved their problem by first rebuilding a moulder knife profile sharpeneng machine and then by buying thicker tool steel in order to grind a front angle on the knives before grinding the profile.

This changed the final cutting angle of attack and the hardwood came out perfect.

My point is that while in most cases we are not trying to cut the opponent, just launch, in some situations, a cutting angle other than blunt and square might help get under an opponent.

So tell me all you know...share...share...come on...

i havent really studied the difference to much i guess you could say, curved/angled teeth are just cooler lol
Both are really effective but i dont think i can actually say that fancy tooth is any better then a flat tooth, the only decent wedge we fought was Good Knight(ti wedge with s7 rails) both fights, one was 3 miniutes the other was a bit over three seconds, both tooth styles got a bite and each threw it pretty well. We dont have any flat toothed beaters so i couldnt tell you how those really compare.
Time will tell?!

Flat toothed beaters bite quite okay.

I agree...it's not a BIG issue..if you get under, then things happen...

biggest part is your lowest point of possible contact i believe

I think that we can finally close the book on Sting's drum related problems...it perfomed very well at Moto....

any video???

We will hopefully have some up in a day or so....in the meanwhile....

Stings first battle vs Ripto 2.0

Sting vs pure dead brilliant we won by tap out after remvoing a blade and a wheel..we did a repaeat of this in the second encounter

It stings vs Surgical strike we won by again removing a tooth and ss went dead

Where's Cody when you need him? he's the master of finding this stuff on the tube

We had a pretty bad loss...war drums vs the spin stops here...tssh was totally dead and getting launched all over the arena, but we didn't tap, in hopesthat the hits might bring it back to life....lol

No damage was suffered...we didn't expect that any would, but we took a pretty bad beating....
