How can I put a 120° bend in 3/4" diameter rod?

Tried. I'm apparently tired because it just wouldn't go.

I did actually think about that....

Sooner or later you are going to want and need an oxy/acet.  Even an oxy/pro is an improvement.  Both will cut steel but oxy/acet is for welding, not just cutting heating brazing.  Primary toy for playing with steel.

[wallfish 15,919]

Depending on your tools, Is it easier to bend the 3/4 rods or drill a 3/4 hole?

Maybe something like this to weld a 3/4 rod into. Might be stronger too. $20 from Northern tool but may find them less expensive somewhere else

This is what I was going to suggest!! 

 

If you are not confident in your welding to do this, you could drill it, fab it, then tack weld it together. Then take it somewhere and have them weld it up. If all they gotta do is weld, shouldn't cost much.

when bending use two pipes one around rod to stand on and one around rod to pull with arms to give leverage. ID of pipes should be close to OD of rod and keep gap close when bending so it stays "sharp". As mentioned leave rod long and cut to length after bent.

So did you get them bent?

Issue there is the tanks are near impossible to get in Maine unless one is commercial.

Not to the sharpness that I need. 

 

@wallfish @RandyLittrell  the idea of the square spindles has crossed my mind and may very well be the way to go.

Are you serious!  I thought NYS was the worst for everything!

Acet?

Oxy?

Both?

Man!  Every farmer has to have a set!  

I've bought medical O2s at yard sales.  I partially fill them with my larger tank.  I even bought an O2 generator at a yard sale.  I think it would be enough for my Smith Micro Jewelers torch.  

Well crap!  Guess I'd become good friends with a business!

The square spindles would give you roughly the same type the GT14 has

Ya to have an oxy/acte set up here in Maine you need a contract thru a gas supplier. It's expensive to start. Contract cost plus tank contents plus tank deposits. Probably 400 to start nowadays? Then your regulator/torch set

Good grief!  It's costly enough without a contract.  There are issues with tanks needing to be hydro tested so someone has to pay for that, whether it's absorbed by the contract holder or the tank holder. Tanks can be purchased or leased.  The volume user might not care but the homeowner, hobbyist or small time user would.  Well, that would leave metal blades and plasma, assuming that CO2 can be had? Argon?

 

Either of those an issue?  Still got tank qualification testing to deal with.

[Kenneth R Cluley 480]

Tractor Supply has oxy acetylene exchange tanks here in FL. Expensive but handy.

[Kenneth R Cluley 480]

EB you said you have a black tank, could be acetylene plumbers torch. Called those Turbo torches. That may work on propane.

I should have picked up on that!  My little "B" tanks are black.  And yes!  if he could get O2 tanks he could have a Oxy/Acet setup.  But...  

Then again, if he can get a "B" tank why not a larger acet tank?

Oh ya, if you pay you can get anything. I have oxy, acte,co2,,argon and stargon

So doable, but some pain required...

 

"stargon".  New to me:

Praxair's Stargon^™ VS is an optimized blend of argon, helium and carbon dioxide formulated to perform well with all solid and metal-cored wires. ... The unique blend of gases in Stargon VS produce a stable metal transfer over a wide range of operating conditions.

Didn't know the GT14's were different!  Thanks!

And I too recently saw the vid.  (probably followed a link you posted...)  Good vid!

Agreed.  

Norman does have some good info. 

 

 

@wallfish

I'm thinking about ordering 2 of those. 

The Northern tool price is the best I found earlier today. 

 

[wallfish 15,919]

Typically enough for most homeowner use, depending upon how much you do.

Here we just swap the tank and pay for the gas. Yeah it seems funny the first time swapping a brand new tank for a used tank but it's quick easy and you always get a certified tank every time anyway.

Nothing better than a smoke wrench for those rusted bolts.

Really handy!  Portable!  I have one.  Won't last very long though...  But it will solve a lot of small problems that are very hard to do with anything else.

Yeah, put a rose bud head on them and it's about like striking a match. That's all I have and it does the job. You can also get just the tanks to have spares on hand which gives some time to get to the gas store for a swap.
