Tovarich pressure

[Crispin]

Have just fitted a tovarich + trigger kit onto an SL 70, lobbed about 15bar into it I would say, would be good to know what pressure other tovarich users are using with a 7mm spear?

ta

edit - lol - some of the medfish guys are putting 25bar into them - bonkers!

I'm using 23 atm on my Toravich and Kara-yo fitted guns. Both guns shoot like they are pumped up to 35 atm.

Do you also have SL 70 and 7 mm shaft?

i use 115cm asso with tovarich kit 9/32 shaft. Over 24-25 bar is not necessary. The gun starts to kick at 25 bar and you really don't gain MUCH more power and it gets harder to load. At 24bar, i have shot cobia completely through the top of the head. It pierces through amberjack like butter.

I use mostly 9/32 nds shafts in my guns. I do have a 70cm gun but it is not a Cressi. My Toravich is set up on a 110 cm Mares Sten and a 135 Asso. I have the Kara-yo installed on a 85 cm and 78 cm Sten.

I believe your guns shoot fine because you use 9/32 shaft. It is thinner and lighter then originally delivered with gun + you use vacuum barrel.
Which one do you prefer: tovarich or karayo? Had you tray you guns with 9/32 shaft before installing tovarich?

24 bar in your gun is like 33 bar in gun with 11 mm barrel - more than is recommended: 30 bar.

Tromic, I was using 9/32 nds shafts before changing over to a dry barrel system. I like both the Toravich and the Kara-yo systems equally, but I prefer the Toravich for my longer guns because the shaft is more streamlined for longer shots. The Kara-yo works great on my shorter guns because of the faster reload times and the only hole on the front of the shaft for the barb.

I believe that adding a second hole on the front of the shaft for the line weakens the shaft and makes it more prone to bending or breaking when the shafts hits a glancing blow on the rock. This is a common occurance for me when I use my shorter guns on fish that are in a hole or close to the bottom.

 

[Crispin]

ok i'll stick about 22 in it and see how I get on with that. Really looking forward to trying it.

Having a bit of trouble getting hold of 7mm spears in the UK atm, not keen on importing them from Devoto really, i've heard it's a royal pain in the ass. I'll ping a few more people and see whats what.

I'm not normally shooting into holes in Cornwall cousy, so bent spears not really a problem, I use an unmodified 55 SL for that job, haven't managed to bend one of those spears yet.

 

[cousy]

You could try getting 7mm shafts from Spearo.co.uk; they sell the Maroisub Mamba guns and I believe they come with 7mm 17-4 PH shafts.

I normally use a 42 cm gun with a four or three prong head shooting smaller reef fish that are in a hole but I switch to a 78 or 85 cm gun with a Tahitian shaft for bigger fish that are in a hole.

 

[Crispin]

thanks cousy - yes Dave@spearo sorted me out nicely, I got the spears done at an engineering shop and they look good, going to make a few more mods to the gun and then give it a go

 

[foxfish]

Hey Crispin good luck with your gun, I like to use a 6.5mm spear in my shorter air guns.
I can easily load a 6.5 in my mamba 90 set at 22 bar.

Cheers foxfish - I did wonder about 6.5mm just because the spears are easier to get hold of, but the weight difference between the seatec 7mm spear and the bog standard Cressi is madness already, so im not too bothered.

I think combine that with everything else and it's going to be a cannon - just got to round off and polish the end of the piston tonight, and then find some synthetic cork to sort out the negativity, and it's done

The kara-yo trigger kit seems awesome - theres almost no trigger travel now, thats one of the things i'm really interested in trying out

I should have blogged all this really, although it's not "that" difficult to do once you get into it - the hard part was getting all the different types of oil and grease for the darn gun!

Maybe not yet but dry barrel guns are addictive thing to own & soon enough you will be after top performance like the rest of us!
Actually there is quite a difference between 6.5 & 7mm in the bending stakes, 7mm is quite a bit easier to load.
It is quite possible to see the spear in mid flight with a dry barrel gun, something that is not so easy with a band gun due to the recoil.
watching the spear travel though the water is great fun & you can get an idea of trajectory & range with different spears.

Yeah im sure when it comes to bendiness there is a lot of difference, before I got the 7mm spears off Dave I used my Picasso 6.5mm to test load the gun, and I did wonder about the flimsiness of the spear....

As for swapping it over to 6.5mm, I'll reserve judgement on that till i've tried it, although I might well get a second trigger kit for my SL 55, just because it feels so much nicer than the stock one. Although you're probably right - i'm fairly addicted already and the thing hasn't been in the water yet.....

One thing I did do that might be of interest is to change the line catch after installing the kara-yo trigger kit. This meant I didn't have to trim the trigger. I used an old plug socket and a dremel I might end up using a reel but this will do for now.

Everyone i've spoken to about the spear ballistics says they dont notice any sideways movement at all from the spear when fired due to it being attached at the front - is that your experience as well?

Crispin, maybe you could tray loading the 6,5 mm shaft with Airgun easy loader. It solves the problem of bending. I was loading Cyrano 850 with 6,5 mm shaft at 27 bars without any problem.

 

[Crispin]

I guess so, but when I test loaded it with the 6.5mm spear - the spear had not been cut down, and was 90cm long, the cut down spears are 82cm, and I think I can get "over the top" of the spear when im loading it if it's that short, so I think I should be able to do it without bending - I might cut down a 6.5mm spear and give it a try.

I looked at your Tomba thread, and while I admire your ingenuity and progress with your designs, they're not something I would use myself, as I like as "clean" a system as possible, and while your system looks great - it's just too complex for me, i'm sure I would have trouble with that loader in the water - especially in the surf or something like that.

But I think it's great you make the stuff yourself and are willing to try something different - I think the world would be a very boring place if we were all the same eh

I forgot to say that 7 mm shaft for Cyrano is 84 cm, with harpoon maybe 90 cm. I was loading a 100 cm, 6,5 mm tahitian shaft. I was Loading it at 27 bars without loader also, but it was match more easy with the loader especially in the water. Tomba has nothing with the loader. One do not need to use them together, so the think is only the half of the "too complex".

Yeah I get that I like your idea, but I think it would still not be right for me personally, i'll struggle on with my standard loader Unless of course your loader will help me with my aim
