Interesting.
Limited use but for extreme pneumatics.

Only just noticed the accompanying video, well it seems to work well enough and certainly it would be handy for these long guns some use or those that just can't load them.

Though I would question the sanity of loading that in the front room

 

[MARMIR]

....Great, helpful device......how much pressure was the gun loaded at?

 

[Jonny250]

Great idea, I love seeing the various devices that people are developing for pnuematic-gun loading. I get the impression there wasn't much pressure in that gun but it demonstrates the point. At high pressure, what would happen if your hand slipped on the winder - would it spin off at high speed whilst the spear goes off into the ceiling? Could be solved with a freewheel or something..
There's obviously a small market for some universal pneumo-loading device judging by the number of efforts to develop something. Good luck with this one

 

[tromic]

Marmir, it was about 10 bars for demonstration. I have tried it at 25 bars too.
Jonny250, it is easy to wind because the reduction ratio is about 1 : 50 and there is also a friction winder-wood, but there is a possibility for slipping, I agree. One have to be careful.

I agree Jonny & I think it is your turn for the next one?
What happened to the mastic gun loader? Any one got the link to show tromic?

 

[tromic]

Here is a modification.


This is the gun with the loader.


One part of the loader is on the gun so it is faster to load. I could not imagine more simplyer solution.

will it only work on a trident tip? i can see that a ss ring went over the trident and that was where the pull was coming from..is there something i missed? how will it work on a regular tip...
seems like loading pneumatics will continue to be a challenge..although this idea is great, i cant see it working while in your in the water..too much stuff to carry around

 

[tromic]

Of course not only on trident tip. I suppose it will not be a problem to make some staff for regular tip.

too much stuff to carry around

That is the price - to carry around some staff more.

Anything else but words?

Arr good point, he does say - "look under Pneumatic Gun's", (My loader). for explanation" but now I cant find that post at all! PASTOR HELP

Is it this one? http://forums.deeperblue.net/668593-post26.html I remember merging 2 threads into one because Geoff posted to a new thread by accident

Tromic,

....I do think that your idea is good and probabily with small modifications it will work very well with 8mm shaft.....but I like to use 6.5/7mm shafts and I think this device will not prevent shafts from bending...

 

[foxfish]

Well I think Geoff must of deleted his post, he did say something about getting a patent!

MARMIR, it should work with 6,5 and 7 mm. But there is a trick. You mast wind the shaft, or the spectra around the shaft few turns. Look at the video again.
I had tried it without winding and the shaft was bending. I had tried the gun on 25 bars with shaft 7 mm. It was working fine after winding the spectra few times.

Hi Tromic,
Here’s a few ideas, I like the basis of your system and for sure winding the line around the shaft is a definite part of the success. The following are obviously not directly suitable, but the concept could be adapted to suit the speargun.

cargo ratchet = pull + lock => less hassle than the winder? (use a larger ratchet handle for more leverage:

Geared winch system e.g. yacht winch = handle can be removed, turn one way for fast turn, turn opposite way for geared turn. Fitted with a ratchet (little bit big tho J )

Then I realise that the closest you might get would be a fishing reel which has the winch aspect and the ratchet – I don’t know about the load capacity tho:
fit your own reel, ready to go; not very corrosion resistant, but a good start, gear ratio 3.8:1 :

just some ideas to throw into the pot, needs more work, I know, i like what you're doing

Foxfish, do you have an old multiplier to try it out???

 

[tromic]

Jonny250, thank you for links. They are helpful. I had on mind all of that staff except reel, but this what I made was very easy to make from wood and a piece of steel shaft. I made it in one afternoon. And it was working very good.
