Russian Xtreme custom torch

[xooler]

We ( I and my friend pofigist) have modded my Bernzomatic torch :D
http://images.people.overclockers.ru/33123.jpg
We have brazed shredder valve and connect it to tank with R290.
It work's :)
Some time later we have fueled my tuned BernzOmatic's tank.
You can see details on picture :)

After filling we have 12psi in tahe tank.
Result:

With 12PsiMy torch work so good... like MAPP gas torch :)
Special Thanks to Pofigist for help :toast:

Wait... You brazed on a propane tank.... Isn't that like risking massively gorey death?

[xooler]

Then we brazed a tank be empty.
I know working with high flamable gases is very dangerous....
we are xtreme :D

[mr-white]

so you've brazed a schrader valve on to the cylinder so you can keep refilling it ?

hows propane going to be good as MAPP gas (http://www.bernzomatic.com/bernzomatic/consumer/jhtml/gasTypeComparisons.jhtml) ?

Yes,i can refill it :D
High Pressure.... it's our secret.
The flame on torch looking great :)
I'll test it on big tubes tomorrow .
The sheme of filling looking like :big tank with R290 and fill adapter por filling- hose - gauge manifolds - hose -compressor-hose-shreder on berzomatic tuned tank in cold water. R290 condensed in cold tank.

Avoid Alloys containing more than 67% Copper!? this is with mapp gas....how can that be?

[mr-white]

so you're creating more pressure when you fill it up than what it came with when you bought it ? whats the pressure difference now and before ?

MW

[wdrzal]

you can fill more fuel if you invert the propane tank and fill liquid, but the smaller one you are filling should NEVER be filled more than 80% of capacity. You MUST leave room for expansion.

[wdrzal]

also i'm not 100% sure but if I remmber correctly that valve on the side of the tank, which it looks like you removed, also doubles as a pressure relief valve.If so it needs to be left intact.

[mr-white]

theres no valve as such on the side but theres a small circle about 3/4mm which could be used as a safety feature in case pressure does get too high.

it also says refilling may cause explosion. Federal law forbids transportation if refilled - penalty up to $500,000 and 5 years imprisonment (49 U.S. C5124). but i assume as he's not in the US that it doesnt apply

Hey,looking good,but u should braze the schadrer port in other place,not the pressure relief valve,and u dont need a compressor to put the gas inside the bottle,just do a vacuum in the bottle and then you can fill with propane or butane easily

[Activate: AMD]

dude.... you're gunna blow yourself up

[Ugly n Grey]

It'll be an extreme explosion in any case. More power to you.

[GuGaCoSa]

12psi is way far for blowing away that bottle,so i think is ok

[xooler]

Thank you guys :)
In next tank we'll made a adapter to use it in a center valve to fill it
I think you can see results tomorrow :)

[Lando95]

Very dangerous, but NICE! I personally wouldn't try it, but congrats on the work! And yeah, 12psi isn't much at all.

[FrozenPC4Brain]

I hope he get a tomorrow!!!

Thats a very hard way to learn. I know, we did some and have a hole to show for it!
SIlly friend thought he should heat it up by fireplace, it launched, it made a hole, it got us banned from that shop for a while, lucky we were out side on a 420. lol
Man I remember the 80's

[wdrzal]

Thank you guys :)

very good and that way you can fill any tank without brazing in a valve,

where did 12 psi come from, there is more pressure than that, thats wrong!

[pythagoras]

Well he used manifold guages to charge so that would be26.7 psi

Regards

John.

[wdrzal]

propane IIRC is some where around 120 psi at ambiant temp.

[wdrzal]

john what do you mean its 26.7 psi because he used manifold gauges? How did you get that from 12 psi?

edit: I see you added 14.7 so the 26.7 is psia........... not psig.......... most pressure are given in psig

[hatemi]

IMHO He isnt rechargint the tanks, only using it to connect the brenzomatic burner to a larger gas sylinder. Manifoild as a regulator and the empty botle just in between the burner and hose so you dont need to braze the schraeder directly to the tip.

[hatemi]

Nah I was wrong :) he is recharging them.

[xooler]

hatemi,
Yeah! I've recharge them :)

[gkiing]

their easy and safe to recharge if you do it right, and you dont need to do any brazing or anything to do it. Actually a better idea would be to get a propane tank --> cga 200 adapter then you can screw your torch onto the hose into the propane tank.. these hoses are very common.

I love mine :)

[wdrzal]

Those adapters are on Harbor freight's web sit for 15.99 they were on sale 50% off in a email I got but that was a while ago. I don't know if the sale is still on.

[xooler]

I think i can get it in russia,but i have hands,yeah very good hands :)
I'll made a custom adapter... I just need big nut 25mm....
