Great and nice work!

Great Video!


Joe

 

Excellent

Nice vid!

 

I love it. Awesome video.

 

very cool.....hope you get all of the kinks worked out

 

Omigosh, Krayvis! I'm staggered. Extremely impressive what you've done with the big guy's design. Splendid modifications! Reversing the position of the magazine, slide lever combo, adjustable 'iron-wood' sights… Fantastic stuff. Great job on your video too! All class. All the way. Woo-hoo!

Laughing… "A jolly German fellow" -- Jörg is really gonna love that one. Actually, he is sort-of like a super cool Santa Clause

isn't he? All those fun toys he designs.

BTW, we don't have any of those crazy NJ laws in AZ. You can pretty much carry whatever you want -- except a bazooka.

 

This is excellent craftsmanship. I love seeing a concept being transformed into a perfectly functional, and very well-styled weapon!
Great job, excited to see future projects!
Oh, and your video was very well done, as well!

 

You and your crew make very nice videos.

That glass bottle explosion was excellent and the "close your mouth" had me laughing.

Great work all around.

 

Thanks for the kind words, guys. The amount of support and talent in this community is a huge motivation for me. I've got a couple more rubber-powered contraptions I want to bring to life before the end of the summer.

I'll keep trying to improve the quality of what I put out, and I hope you'll enjoy the results. I know I'll be giggling like a child if even half of my ideas work out...

 

Fantastic job on that weapon and very nice vid too. Love the destruction part, thanks mate.

 

I really like your videos, because they are very well made.
We all very appreciate your awesome work!
Keep it up, please!

 

very good video

 

Thanks guys

Here's a few pics of what happens after prolonged use. It would appear that a wood edge sanded down with 220 grit sandpaper still has enough friction to wear down paracord. This is the first piece of paracord I used, before replacing it with a new one. I have since applied a little bit of wax to the cord and wood parts. This not only reduces friction, but because melting is a phase transition it soaks up a lot of heat as well if I'm not mistaken.
The new paracord has survived a dozen and a half shots under even greater tension relatively well.

I'm wondering if a a quick coat of epoxy or super glue on the wood, then sanded down, might provide a plastic-like finish that's smoother than wood...

 

I usually put a little tape, duct tape or electrical tape, on the parts of the string that has contact with the wood. it lasts a long time and then you just have to change the tape when it gets rough. Lasts a long time, tough

 

Nice video/test

 

Failure, thanks for the tip. I'll give it a shot in the future.

 

Hi Krayvis,
I would put some metal pieces where the paracord come in contact when sliding and, instead of paracord, i' ll use iron cable from a bicycle brake. It will last longer for sure but i don' t really know if it is "compatible"... Just an idea

 

I always sand those parts that come into contact with the paracord with 80 grit, then oil it with linseed, go 400 and 1200 grit, then oil it again.

The sear and the sled are the most important parts to be polished.

 

So fierce.... I definitely love it!

I think you could simple use felt ( not sure of the word, so I add an image ) :

it' just a simple part of condensed fibers, you can cut it to fit your wooden part and glue it so the paracord will not be sawed by the edge of the wood
It's quite resistant, and really cheap. Plus, I think it'll be discreet on your design
It's 2mm thick, so I think it'll be enough to protect your paracord from friction

I dont think that it will really works for a longer Time!

Make it so as Jörg wrote!

Jörg has enough experience!

nice vid!!

 

Thanks for the excellent advice, Joerg. I will give it a try, though I only currently have up to 600 grit in the house.

Stringsling, not a bad idea, though I think Joerg's is more permanent. And probably good practice for future builds, but thanks anyway.

P.S. I apologize for the accidental empty post earlier.

 

Of course Joerg's is more permanent

I watched your construction video [ame="http://www.youtube.com/watch?v=xdSv8vLR3Ns"]You can watch the trigger mecanism at 2"20'... but the rest of the video is great too ^_^[/ame]
and I think your trigger mecanism is very clever.

I'm looking forward to see your future improvements... and blueprints

[edit] BTW, I'm personaly not sure that the the slide dispenser HAS to be triggered by the pump mecanism. I think manual chambering gives a dreadful touch to your work.
Congrats again
