50v Vulcan

https://www.youtube.com/watch?v=ioGuFNrB9sM

I fried my Vulcan recently while jerking around with it.

I had some other motors I got for the Stampede some time back but never used, so I fitted one.

This was a slower motor, but much torquier, and works excellently (more good luck than good management).

Good ROF and smashing solid 70 feet plus using blue snap cap stingers.

It's funny cause this motor is slower at 50v than the original at 33v, but you can really feel that it's more powerful and is doing it easier.

Check it out.

Nice work on the vulcan mod.

If you can get some more of these motor and add them to Ebay I would buy two of them off you.

Thanks,

I need to track them down again, as it was some time ago.

I've got 4 left and I want to use them in my other Vulcans and Stampedes.

I was dissapointed at first when it was slower, but the whole thing feels better.

I've got plans for a sealed breach (notice I didn't say brass) Stampede with a really heavy spring and a permanent cure for the autofiring problem, run at high volts/ROF.

This motor might be the go for that.

Looks good mate.

As always, you can count me in for some beefier bits n pieces!! haha

Cheers,

so this beefier motor would be better for driving stronger springs, right? even though you'd have to run a higher voltage to get the RoF up anyway, there'd be less chance of burning the motor out?

This does appear to be the case, but obviously there's no guarantees and I don't have any to sell at this stage.

This Vulcan is just my pet project I like to play with time to time.

oznerfnerd, is that 70ft flat? Also wondering what else you have done to it?

Nice work! Would love to see this with even heavier springs since it seems the new motor may be able to handle it.

that's true, nothing is ever really guaranteed with nerf haha. it's an awesome little project though.

No,

That would be firing it roughly at the angle you see in the video, about 50 feet flat.

You'll notice that while I'm firing the second belt I lower it a bit.

That's because it was nailing the shit out of the flat screen TV which is about 53 feet from where I was standing and 1.5m off the ground.

This was using unweighted snap cap blue stingers, it really likes them.

I've got a quite heavy spring in it that I found in a spring kit in a heavy machinery workshop, one of my heavy recoil buffers and the same teflon lube as in my spring kits.

I have drilled out the AR completely.

The only other things I can think to do are glue the clutch and fit a slightly fatter o ring.

To get any more out of the vulcans i have, i will need to have the plunger arm made out of aluminium, since they like to break into two sections when put under to high stress.

Have you considered a black polymer/pvc type plastic?

you know, you can mould stuff like this out of resin.
here is the guide

The arm also contains teeth which need to mesh with the cogs to load the plunger. It might be possible to do from resin, but given where the weakness is i would still look at aluminium. Arm is under horizontal stress with two opposing forces at work which can tear the arm into 2 sections.

Ahh yes,

Forgot about that.

Because I haven't broken it (yet) I've paid no attention to it.

Would you consider brass (or too heavy), as that is a material I have seen used to mesh with nylon, delrin, etc gears.

It's got to be too heavy when you think about it.

The spring I'm using is pretty stiff, so I'll add a slightly tighter o ring, up the volts and see what happens.

Break out the fire extinguisher!

You're going to go more than 50 volts?! holy hell this should be interesting!

oznerfnerd - I would consider marine grade stainless steel, weight isnt the issue. But machining marine grade stainless steel is a pain, aluminium is just easy to machine so is brass and copper. I just prefer aluminium.

I have broken about 4 of these arms, especially when testing vulcan springs working backwards through load rated springs from about 13kg. The 13kg & 12kg springs both tore the arm half, the 11kg i have run through all my belts 5 or 6 times and it still keeps firing. Hence why i am now selling that spring.

Sweet! Put my name down for if you manage to track down what exact motor it is and where you got it from please =D

Well I guess 11kg's is the limit then.

To be honest I couldn't be bothered trying to machine up a new arm out of any material, so I'll stick with the spring I've got for now.

My next move will be to glue the clutch solid and see how it handles a circular belt run for 60 seconds.

If it does that, I'll up the voltage and do it again.

I don't know why I'm so cruel to it, it's never done anything to me....

I just love that mod nice job, like it.

You dont have to answer ... (Or you could just PM the Answer)

But to my untrained eye .. I would say it is this motor

Am I right ?

Mate,

It's not like it's a big secret (to me anyway).

No, this doesn't look like the exact same one but it may fit and work.

As I did say, I got a couple of these motors some time ago and never used them.

I am looking into getting more, and if I can score them on a decent number I'll put them in my store at a decent price.

I'm sure there are numerous suitable replacements out there.

50Volt... crazy.
I'm happy with my 14.4Volt Nimh custom battery pack.
I have one of http://jaycar.com.au/productView.asp?ID=YM2716&form=CAT2&SUBCATID=983#1 waiting for the day I burn out the stock motor.
