All he has to do is do up a cad and get it all custom machined and it dont cost him a penny (sponsers pay it all)
LOL @ Ian - if only ! Yes I draw something in CAD, and then I get a completed robot posted to me.
No disrespect to you Ian, but I think you need a reality check !

Im up to whats on my profile pic (about to load) at the moment. Thats a 50cm titanium, vertical spinning blade... Ill be going to rcwars on the 18th, is anyone else going? :)
Cheers, Ewan
Yeah im going to watch,
and from what i have herd, no roof on the arena, so i would have thought RC Wars wont be allowing your vertical spinner to run. Unless they get a roof put on which is better than Romaing Robots roof.
Also ewan, the motor is fixed somehow to that big wood thing. The big wood thing is then somehow attached to the wooden base. I would personaly not be happy due to safty of that running at FeatherWeights.org event how it looks in that picture.
Mr Stu
I think Alan Young said something about them having a roof that they put over the arena Stu - am sure I read it somewhere. There was a time when you could question whether you needed a roof with a feather spinner, that certainly aint the case any more !

(to Craig-) Its a very big featherweight vertical spinner, thats my point. (to Stu) The whole weapon structure is screwed together by the eqivelent of 6mm bolts, only they are screws. The wood is 2cm Mahogany (tough stuff!) with 3cm softwood.
If RC wars doesnt have a roof (thought it did have) then I myself am having second thoughts on running it there. Ill have to see what happens...
It should be perfectly safe at featherweight.org, as that has a roof...
Cheers, Ewan
Ed, it didint have an arena roof, few people who went to the event last time confirmed to me it didnt have a roof, and spinners were running.
Slow Speed ish horizontal might just be ok, how ever not recomended and wouldnt be at FW.org events, but i hope they dont allow Vertical Spinners to run without a roof. Even a small low Knetic Energy blade like Kitty can make a big peace of polycarb and bits of metal fly over an arena as high as Roaming Robots.
And it did. (But was contained by their roof.)
Mr Stu
(Ewan posted before my last reply, this post is to reply to Ewans reply, how many replys can i put in this reply sentance?)
Ewan - i dont care if its special wood shipped from the rain foresst - wood supports for a big huge fast spinner like that - is not safe full stop mate.
There is a high chance the arena we used at FeatherWeights.org (Roaming Robots Feather Arena) would contain a spinner like that. But if that spinner was at full speed and took a direct hit by a horizontal disc, that blade and motor is going to go flying and may get stuck into the polycarb screens. Yes it may contain it, but will damage the polycarb screen due to your unsafe built robot.
Yes robots will get smashed and bits will fly, but not a whole spinner with its motor attached to it. If that was a heavy weight and at robot wars, it wouldnt be allowed. But as its a feather weight they would. But a feather weight like that in a feather weight arena - no no.
Mr Stu
Im concerned to hear that the RC Wars arena has been running robots like Tantrum in previous events without a roof in place - particularly concerned given James Cooper put a post on the forum defending the safety of his events.
James - perhaps you could shed some light on this - did the RC Wars arena have a roof on it last time. If it didnt - I believe you may have just found out why people have been worried about safety, and I also believe you may owe people an apology for your rant in the other thread about how safe your events are.
I understand that the FRA is sending a delegation along to have a look at your next event - lets hope they only have good things to report going forward !
Ed

On the basis that theres no way the spinning mass would be able to penetrate the Roaming Robots Arena if (when!) it comes off, and on the assumption that the robot passed its tech checks I dont see why it wouldnt be allowed to run.
It would certainly be worth watching though Ewan, Im not sure it would hold together. Only one way to tell though !
Ed
http://www.stormrobot.comhttp://www.stormrobot.com
Doing Stus multi post thing !
Sorry Ewan, doesnt look like it will run at r/c wars...its not up to me to diside but unless you re-engineer that robot dont bother bringing it in, in the thought that you will be aloud to run...Im speaking mainly for myself hear but i have been to all the resant r/c wars events since and before they put up there new arena..I dont belive it has a roof at this moment in time either.
Also if we are very cautious of running tantrum on 1/16 th power I doubt you will be aloud to run on full wack.

Stu, Wood is stronger than you think...
The whole weapon pod is VERY strong, and has a foot area (in contact with the base) of 60cm2, this is connected to the base via 8 6mm screws. When you come to RC Wars (might not run the disc unless he gets a net or something) I will show you its true strength. Oh, and thats a 12v motor run @ 24v e.g. Ive got LOADS of speed and LOADS of torque from that weapon motor...
Cheers, Ewan
we are attending the RC wars event. we will be looking at the safety of the event.
Ewan, have you talked to james about coming to the event, last i saw you werent on the list and i know theres no space for any more.
Im unsure if RC wars arena has a roof. I know tantrum has ran at 12volts.
I am definately going, he comfirmed me via email, just I wont be running the weapon...
Cheers, Ewan
Just seen a pic of the RC Wars arena, if that spinner was spinning at full pelt and hit the wall - hmmm could be very iffy.
Glad u aint running the weapon Ewan.
Mr Stu
Ok all,
Rc Wars hasnt had a roof and hasnt ever run a vertical spinner! not even trilibium. Tantrum was on low power.
Due to the venue beeing so small the roof is bearly higher than the arena. for this next event we will be covering the beams above the arena to stop any ( somehow ) flying vertical debris from getting any where near the roboteers.
Also if we have time we maybe upgrading the front screens to 15mm. if everthing is ok with the sponsers. so i am confident that anything in the arena we will contain.
kind Regards
James...Venom
I should point out as I was the last RC wars event that the spinners running ar rc wars were Tantrum and BS both horizontal.
The arena is also indoors, the question should not be did it have a roof (I honestly didnt notice (3 hrs sleep)) but was there a significant gap between the walls and the roof.
Previously I would have questioned the size and speed anything would be launched in the air by a feather spinner but after vortex launched our tail at inspire I dont see how I can.
Stu the arena walls would hold up just fine. We tested tantrum in there b4 the events and hit the wall at full speed, buggered the spike up but nothing else. the wall is 18mm wood sandwiched between 1mm steel both sides
James Im sorry - but this isnt what anyone wants to see from someone suggesting they are a professional event organiser.
In your other post you said in the safety section of the forum you said :
So far i am correct in saying that we havent had ONE event where anything has jeperdised the safty of that event.
..... but you were running spinners in an arena without a roof. And theres no such thing as running a spinnner at low power, something could go wrong and it could spin up..... and on that note but youll have to excuse me if I point out that in your last two posts :
Rc Wars hasnt had a roof and hasnt ever run a vertical spinner! not even trilibium. Tantrum was on low power.
and
We tested tantrum in there b4 the events and hit the wall at full speed
....do seem to be somewhat in contradiction of each other. Either its safe to run tantrum or its not. Has Tantrum been run at full power or not, or does it depend on which point you are trying to make at the time ?
Also if any body who has been to one of our past events and would like to share there oppinion on how that event was handled, it would be great to hear from you.
Its clear from Sams comment above that he didnt even realise the danger that you were putting him in by running an arena like that :sad:
Your suggestion that somehow flying debris will get out of the arena suggest you dont know what youre dealing with. Vortex removed the tail from BS at Inspire and launched it hard into the roof.
Defending the safety of your event is one thing, but to suggest that your track record was to the point of not having ONE event that could have compromised safety on a public forum, and defiently lay into people who felt it was dangerous is bang out of order James.
If you want to exist in the real world, you need to buck your ideas up. Sorry to come down on you like a ton of bricks James, but Im just telling it how it is.
When it comes to Safety, half measures wont do - and misleading people just makes a bad situation worse.

what would happen if a spinner if flipped into the polly carb walls?
Ed thats completely understandable, i wish there were more like you, your critersisms are much appreciated.
first of all vortex is a bloody powerfull vertical spinner so its bound to send things upwards :p. we havent ever run a vertical spinner. i think the piont sam was saying (correct me if im wrong please ) is that the roof was very low anyway??? the gap between the top of the polycarb and the roof is quite minimal, so anything going upwards would of had a hard time getting out. still not impossible though therefore we didnt run vertical spinners
unless we do get a roof sorted or ajust the venues roof we still wont be running vertical spinners
A spinner like Ewans, Vortex, Kitty, Black n Blue, Strip, Arrgh, Tantrum - i dont want to imagen dave.
Robots like Aaargh can already penertrate 6mm ali just hitting it. Imagen him being flipped into the screens of 5mm poly - i wouldnt like to be near it.
Mr Stu
thats why we wouldnt run most of them because they are vertical spinners. tanrum was run on 16th power and there were no flippers entered that event. if there had been would would think twice about running it
James, Horizontal Spinner + Flipper/Gyroscopic Forces = Vertical Spinner
You also cant run a spinner like Tantrum throttled down unless its mechanically throttled down so it physically cant go any faster.... and if you read what you wrote, youll see that YOU said you ran Tantrum at full power !
You cant delimit between the two sadly as one soon becomes the other as youll see if youve read the FRA Safety guidelines.
For example, the Robot Crusade are screening all the way up to the top of the roof because a horizontal soon becomes a vertical, and thats even with a 6m high wall ! Theyre still considering what to do this year even with that !
Ed
http://www.stormrobot.comhttp://www.stormrobot.com
erm we ran tantrum into the wall at full power (like i said) before the event. during the event we ran tantrum at 16th power. we have never ran any spinner in our arena with a flipper, if a flipper was to enter we wouldnt alow tantrum in and James Baker knows that. Did you know Rc Wars is a 50/50 with me and James Baker?
James, I think this is a conversation that should be best taken off the forum before you say anything else that continues to dig yourself a hole. I do know that youre 50/50 with James, and if I were him Id be reading what you were writing about your joint venture and cringing if Im honest.
The FRA are coming along to your next event I believe - Id suggest you finish by apologising for your rant stating that RC Wars had never done anything to compromise safety as its become clear thats not the case, and communicate with the FRA !
Ed
http://www.stormrobot.comhttp://www.stormrobot.com
is this a forum or chat room? :)
the best thing is to wait and see what the safety of the event is like.
Ewan, if it was me doing the tech checks i wouldnt allow your robot.
yes , lets wait and see what your representertive have to say. i look forward to hearing there thoughts and oppinions and will welcome all constructive critsism
Nor would alot of people Alan.
Mr Stu
constructive critsism
Paint job of the arena one of them? :proud:
Mr Stu
Damn i best get the paint brush out before i buy some polycarbe screens which i lied about haveing. which ones priority. damn too many chooses il go with the paint work.:p
Just thought Id tell you that this bot is called Big Daddy, because it is BIG Im talking 50cm high, 60cm long and 55cm width!!!
I do think It is perfectly safe as long as the arena can handle the weapon. Ill show you lot how really strong this beast is at rc wars (Im gonna fit a wedge onto it tonight)
2 points, first, see RC wars thread for my opinions on the above,
second, tantrum was mechanically limited by running on 1/4 voltage. If thats not good enough for some people, perhaps you can suggest a better way of limiting its power than limiting its maximum voltage? Just asking, as the comments seem to imply Tantrum was inspected and it was clear I was at 1/4 throttle... which was not the case.
oh, Ewan, dont get your hopes up, that doesnt look too secure. Its not the supports Im worried about, its the way its connected to the motor. But, you could always run without a weapon..
oops, forgot to address the roof issue, there isnt one.... an issue that is. end of.
I have now said this LOTS of times, but Ill show you how really strong the weapon is @ the event. Right now I am fixing BIG steel strips down the center of the bot for extra strength.
Oh, and will you at least let me do a spin test (not hitting anything) in the arena, Id love to show you lot the hum the blade makes at the full 2500-3000rpm!
Cheers, Ewan
ewan, alot of us are more experienced than you are. Lets see how strong it is when it hits Alphas stainless steel scoop. Any robot that has bolts sticking out, because theyre too long, shows its not had any time spent on it.
Ah, all those bolts have been turned in, that pic was taken only just after Id got it together. One bolt on each side is still sticking out, as this stops the bot resting on its side, or back...
Cheers, Ewan
P.S. If the spinner hits a solid enough object (like a 6mm stainless scoop) then Id expect the blade to just stop, The bade will fail, before the structure holding it does.
I reckon that motor shaft is gonna bend like hell. Really ewan, the minimum standard for all these super spinners is (for a vertical spinner) a decent axle (eg 15mm EN24T or the like), supported on both sides with some chunky bearings or bushings. Running discs direct from motor shafts is fine on antweights, but i think we really need something more secure for feathers. Put it this way, Id be happy to stamp hard on vortexs disc, because its built like a tank. I reckon yours would not hold up at all to a good stamp. What it really needs is not minor improvememtns here and there, but a completely different appraoch to your spinner design.
Wait and see... Oh, Ill try that stamping test :)
Cheers, Ewan
yet another change in conversation! wot have you got controlling the disc motor? i suggest you put nylon locking nuts on the bar (or at least threadlock).
The Bar is held on by two nuts, tightened to the tightest that the word tight could possibly mean...
Bashing the whole weapon assembly, (and the rest of the bot) with a hammer, can not cause any problems anywhere around the bot, and YES I can stand on the weapon motor (hard to balance:)) without any base distortion etc... I have just fixed the titanium wedges that I will use for the weapon at the event.
Cheers, Ewan
load isnt the problem with nuts coming loose, its the vibrations.
