Forward Assist for semi-only guns.

I would be interested.. Won't be a problem assembling them..

[Stickman]

like mat i am more than happy to distrbute them for you. i have all the gear here to do that.

The original guy that pinged me about all this wishes that he gets it all first.  Since he "started it", that is fair

But no worries, one way or another, you will be able to get them easily down there very soon

I am thinking just "kit"s of a dozen (no fancy $$ switch) is the way to go...  Then you can whip the the basic part up locally for all your pals at minimal cost.

No problems, I need to get a couple to demonstrate to our club leader and a gun store here who are looking at some lead based fuse?? sounds a bit slow and they look large, but come to the same end effect..

Having a look to see if i can get a couple of equivalent poly fuses locally, not many places stock them in a good range..

[Stickman]

dont worry dude. im sending you down a couple when they get here

[kiwi_mat]

thanks that will be good..!!

aparently there are not enough words in this post.. (so I am filling it in)

I have 150 boards and fuses coming in here within hours so there are plenty to go around   The high quantities are cheaper and I don't have to worry about reordering.  My cost is $1.00 each for the board, fuse, and heatshrink.  The #20 wire and switch you can supply.  The easiest thing for the switch would just be two tiny screw heads that could be shorted with a coin.  They also make nice $25.00 switches too   The switch is a bit tricky in that it has to take those 100 amp pulses too...

[Stickman]

how many of thoughs $8 switches do you have. could you send me say 10 of them and some wire. as im sure there is people that will want a no need to build option.

[Gandolf]

I have all of the real live parts now!!!        Of course, this one does not have many parts



I will make some up later tonight and see how it all goes....

How many of 'those'* $8 switches do you have. could you send me say 10 of them and some wire. as I'm sure there are* people that will want a no need to build option.

I got ten of them, but they have 1918 more at Digikey  As late as it is now, I 'could' have them all here before noon tomorrow - Saturday!!  So no worries about 'getting' them.    The switches "feel good"!!  Like they have some serious bad a$$ metal contacts in there!!  Of course, if you want a known number, I can order them for you at my cost for far less than the 'official' $8 price  When I have to buy them 'blind', I have to worry about risk and carrying costs (I have a very BIG scrap parts box   ).  But if I am just drop shipping, the only added costs above my out of pocket is for the beer (NOT cheap!!)  

So the plane is:

1.  I will smash a new switch just to see what is in there.

2.  Build a full unit up and run it like 200 times directly across the 12V battery to see if it is "real tough"  

3.  Smash that switch to examine the contact wear and check the poly fuse to see if it feels some stress.

Maybe repeat that if anything looks questionable.  But if it can take that kind of s***, it will be super fine.

Stay tuned  

I love this stuff    Especially when others will pay for the parts I get to play with!!

*Some corrections to keep HS5 happy  

=====
UPDATE #1

Here is the main unit





Here is what is inside a new switch:



The system is setup for the test but the battery is charging.........



UPDATE #2



Here is what a direct short into the circuit looks like.  The fuse itself has significant internal resistance so the current is limited resistively.  



The fuse brushes that hit off in ease after 200 hits...

So I tried it for 200 more hits into a motor...



Zero care there...

I played around with a Systema motor too...  Still pretty dull, but...

After all that, here is how the inside of the switch looked after all that torture...  BURP!!     



Maybe tooooooo much over engineering there...        But the price is right and the size is right so who cares...

The fuse unit itself is perfect!!  I did not go to the trouble to make a micro picture since it looked 'better' than new  

So it easily repelled all the "torture" testing without a flip or care  

The only thought I have is that Neodymium magnet motors might like the dual version...  Since they have high current needs, maybe the double current two fuse version might be better there.  The board has that on the "back" to add a second fuse...  So the kick power is 4X since it is a current squared thing...

You are swimming in gold there now in any case.        

This one is all solved now

It took me awhile, but today I finally got the package priority mailed to Stickman (he startted it all  )    Enough for about 45 units and ten of the switches (I have to save a bunch for when the German's start calling too )

Let me know if there are any problems.  It should be all cool though. 

[Stickman]

recived them. thanks. going to send them out asap for field testing.

Hi, good idea (again!) :p
I'm living in France near Switzerland so a lot of German guys come with their AEGs to play with us and they always bring a "full-of-tools" box with them but it's long to wait for someone who has to fix his (or her) AEG.
So if you want somenone near Germany to distribute them, I can do it (how much does it weight fully assembled ?).

Cool!  Let me know how many sets of parts you want.  I don't have a lot of the switches but I can get more easily.  The switch weighs 3.3 grams and everything else is probably less than 2g so I would guess about 5g total.

I sent you a PM

have been feild testing these. they work great. cheers
