Torch hose reel

[I Bleed Blue]

Well the only oil would be a machine oil from them being manufactured. would the solvent take it off if it have any inside it?

Petroleum products of any kind tend to spontaneously ignite/explode when exposed to pure oxygen. If your reel uses any oil in the fittings at all I'd be careful.

I'd be worried about oil on the oxygen side, make sure there is none not even a trace.

what oil? and why? I will run acetone thru them before I do the finall assembly. What would the oil do?

I'll let you guys in on a little secret>>>>> But you can't let any body know...... Hee Hee. Build your own hose real I'm in the process of building my on set for my shop. I'm tired of rolling my 100"er up.
Here's the seceret. they use 2000 psi car wash swivels on each end of your real.

Use a large sprocket and a cheap drill fold a metal box around the drill to make it look like you got a motor for it. find a bycycle sprocket that free wheels one way to attach to the drill so it will spool out freely. that my plans anyway.

I still have some parts to collect before I start the build but a friend in OK. built something sillimar with a hand crank.

I'm not a expert so if you have any Ideas I would love to here them

Oh yea. the swivel O rings are made to handle the acid these truck washes use so the acid in the gas won't even be a problem.


Email me your number if you want to talk more. I drive for fedex and own a small welding co. not much time to type.

I tend to agree. I have arrestors at the regulators and the torch. I view it as a belt and suspenders kind of thing.

I run a rosebud almost every day on a set with arrestors at each end, with no problems. I must be using high flow arrestors or something. Still get 10 psi on Acetylene and 50psi for the oxygen. Have run a rose bud large engough to consume 14 psi of gas, never had a problem. The only time the rose bud backfires is when the tip gets too hot after long periods of heating.

[jwsrep]

Having flash arrestors at both ends is okay as long as you don't plan on ever running a roseud heating head. Having the arrestors at both ends will restrict gas flow. It can be dangerous when you are using a rosebud. A restriction of gas flow can result in the flame burning back into the torch from a result of starvation. Just my perspective.

Oh BTW, Cox Reels make a nice hose reel.

here is a thread with some store bought ones.

coalsmoke made his own and has a thread with some good pic's and a "how to" in it. i'll see if i can find you a link to it as well.

as for the Flashback arrestors,
i think a good set at both ends is the best way to go. some (probably most) torches now have them built into the handle but have not seen them built into a hose yet. still better to be safe than sorry.

[JonnyTIG]

Flashback arrestors at each end of the system is the way to go these days. I learned on equipment without any RFCV's or arrestors however I use only equipment set up with at least one set on the regs or the torch, prefferably the torch.
Now I know we all remember to keep the torch lines out of the 'lind of fire' when we cut plate and such except sometimes. Should it happen that a molten piece of material fall on the hoses and burst the lines into flame....do you run for the valves on the bottles? of course. Should this situation put thee into a pile of sh*t in a hurry, then flashback arrestors were needed at the regulators. In reality, the hoses don't burn very quickly, giving the operator time to shut things down. On the other hand, the potential for a bad situation is present.

My suggestion is to use flashback arrestors, at the torch or at the regulator, if affordable use them at both ends.

May save your equipment some day, or your life.

Does anyone have a good source for a cost efective torch hose reel for "t" type hose? a manual wind would work just fine, what are the proper flashback arestors? are the ones that mount to the regulator or torch better? thanks so much for any help!!
