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

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).

[ewan]

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.

I have decided that Ill make improvements on this bot, and will definately keep it for the FW smash.
Because I cant use the weapon (at RC Wars), Id like to ask bots like tantrum and venom (nasty weapons) to not use theirs. Please.
Cheers, Ewan

Oh, to make that clearer, if I could ask nasty weaponed robots to not use their weapons against ME, you can use them against everone else
Cheers, ewan

OK, I know I said I wasnt going to say any more on the subject of spinners but we are past the good humoured exchanges with Ed over his alleged new machine.
What we have here is a situation were there is a very good chance that someone will get seriously hurt!
Ewan, look mate, you are clearly very interested in roboteering and Im pleased to see such enthusiasm. But take it from me, what you have there IS NOT SAFE€¦.END OF ARGUMENT!!
It€™s only my opinion, but what I think you need to do is instead of building multiple machines and running into the same problems each time, just concentrate on one robot€¦and before you even think about picking up a screwdriver, sit down , take several deep breaths and think very carefully about what you realistically want to achieve, given your own abilities, tools and available materials. Yes, you may want to build a Vortex but both you and I both know it ain€™t gonna happen! (yet!)
So try this€¦ forget your spinning whatever€™s (for now) and put all that enthusiasm that you clearly have into building the best chassis and drive you can. Just remember if you aren€™t sure about something there is absolutely no shame in coming to this forum and asking €œcan anyone help me with€¦?€ In fact you would be amazed how many roboteers will be more than happy to help you.
Once you have your running chassis that is strong and reliable as you can make it, even if it has no weapon, bring it along to a Roaming Robots live event. Even if you don€™t want to run it, there will be enough people who will be very happy to take a look and will no doubt offer you much advice as to possible improvements! Again there is nothing wrong with saying €œwhat do you think of this?€ I promise no serious roboteer will ever rip the piss out of what you have done, and in fact you will earn a hell of a lot of respect by doing that. But one small thing to remember, most of the people who will offer you advice know a hell of a lot more about robot building than you do at the moment. I mean no disrespect whatsoever to you by that statement, but it is a fact. So listen to them!
OK, so now you have a solid drive system and that€™s halfway to having a good machine!
At this point there is a couple of ways to go. Take your chassis, add a shed load of armour and a couple of nasty spikes and you instantly have a respectable €˜rambot€™ OK, not the most dangerous machine but a very good starting point for driving practice and you can safely use it in virtually any standard of arena.
The other option is then to add your weapon of choice. If this is going to be a spinner remember what I said at the beginning and BE REALISTIC with what you hope to build and PLEASE ASK if you have the slightest doubt! (one hint, never even think about hanging any kind of spinner on an unsupported motor shaft!)
When you have something you are happy with, again, run it along to a live event and subject it to a proper inspection under FRA rules and hopefully it will pass! If it doesn€™t.. no problem at least you will know what needs attention.
If all this takes 6 months or a year don€™t worry, no one has set a time limit on building a robot, and in the end you will have a robot that you will be proud of and above all is SAFE!!!!.
Good luck, and happy Roboteering,

Geoff.

well said.

Well, I DO use cad for doing first designs on my bots, and I try to have an idea of what I want to build first. I have already gone through the starting stage for roboteering, and entered my last feather into RW (most of you know what happens ) And I entered the FW smash with a robot before that. If you are coming, or if anyone else is coming to the RC wars event, then Ill show you some videos of me trashing a 6kg industrial bin with Big Daddy. Like it or not, this bot IS safe.

CAD does not make your robot good. Neither does CNC. Your design makes your robot good. CAD just helps you get there.

[blazerbotics]

Featherweight Discs

yes we do know what happened at RW, you drove into the arena and the wheel fell off!

[teammad]

Ewan, so what if you can trash a 6kg bin? It doesnt make your robot safe! Please take note of what people are telling you here. People are giving you good tips but you stear away and still say your way is better. Please take note!
