TS3

[calumco]

Ordering some bits over christmas for it, running on better mounted 18v drills on a 6s lipo with a selfrighter too hopefully!

same sorta shape and design but altered to have a self righter built it.

weighed about 11.75 kg without batteries so a lipo and self righter should be do able!

few pics of TS2 after its fight with NST....

amazed at the power of NST to split 22mm thick Nylon

Re: TS3

That is a big chunk out of very thick nylon.
Any thoughts on changing the armour to be more NST proof? (tricky I know)

[calumco]

Re: TS3

all it'll need is a bit more hardox in the front area then jobs a gooden! NST got a few good hits on the sides and so did Little Spinner 4 and it took it well

Re: TS3

Looking good mate, we have yet to actually fight :P

Re: TS3

Is that an old drum roll chassis? Looks very much like a jamie design with how tight everything is in there

Re: TS3

looks a bit like it ye but nope it was all mine

Re: TS3

What about using HDPE for the uprights?

I know its not entirely comparable but with a glancing blow NST shattered my 10mm Nylon base on conker. The only reason it didn't fall apart was a single screw in the middle of the machine.

The rest of the armour was HDPE and it stood up to the hits far better as it could bend and flex a little.

Its looking very promising though! I am more worried about that now than I am about 720!

Re: TS3

Yeah, we have used HDPE for our bulkheads and hope the slight flex in everything will help it survive. It certainly helped with being flipped at MMM.

Look forward to seeing what you do with this, man. Very inspiring to see a spinner within our capabilities do so well. Brilliant impacts for a single s900.

Re: TS3

Thanks guys, thing about HDPE is as a structural material is it a little soft? i was worred about it mabye bending/warping/ or taking damage easily. I no nylons strong and tough but as mine split its mabye not so good as flexing as i hoped it would be. I'd never use any thing like ali because once thats hit and bent thats it, it'll stay like that. think i may just go for the nylon again but do things a bit different at the front of the robot to make it a little stronger.

god thinking about robots on christmas day, how sads that lol :P

Re: TS3

Hey my christmas present to myself is letting myself entertain the idea of a heavy weight Conker with interchangeable 400mm bar spinner and hydraulic crusher :-) So its not that bad.

Merry Christmas

Re: TS3

It's worrying that NST can crack a 22mm Nylon bulkhead!

HDPE comes in several grades but is generally very soft..... Impressive impact resistance so swings and roundabouts I guess. Our plan for BitzaMk3 is thick HDPE bulkhead so we'll let you know how we get on.

Re: TS3

HDPE wouldn't be likely to crack in the same way that the Nylon did, but I would still choose Nylon over it for areas such as spinner bulkheads. It's harder-wearing so can stand up to the forces and revolutions of spinning weapons, whereas with HDPE being softer, although it has a tendency to absorb and spring back from spinner impacts, it's more likely to wear over time and lose its trueness (if that's even a word) potentially resulting in misaligned spinning shafts and such. That in itself can result in more friction in the setup which reduces the potency of the weapon and can exacerbate the situation.

I think the cracking just highlights the amount of power contained in NST's weapon. Whether that was just the one hit or whether the previous hits had partially weakened that area, I don't know. But I think some bracing/beefing up at the front of Drumroll is in order after seeing this :P

Re: TS3

HDPE is indeed softer, but it's not that soft. A bit of our bulkhead was cleanly cracked off at MMM. It's not chewed and twisted, it was a clean separation of two pieces. That's the white stuff, though, it might have different properties to the others. Point being it's flexible but isn't beyond use for bulkheads, it seems.

Also I believe Intertia XL's spinner uprights are HDPE?

Re: TS3

I personally prefer Nylon as I've found over the years that compared to HDPE, it's better for load-bearing and structural parts as well as for wear resistance. But that's not to say that HDPE can't be used, your two cases of Tormenta 2 and Inertial XL being examples of HDPE serving well.

Ultimately choosing between the two can also come down to personal factors. HDPE is cheaper, lighter and easier to work with than Nylon so it can often boil down to what suits the budget best.
