Where can you acquire NON-Galvanized steel pipe?

Mt friends have found plans to build a forge, and we have all the parts to build it EXCEPT for non-galvanized steel pipe. Because the pipe will be heated up, we cannot use galvanized steel pipe as the zinc used in the galvanization process produces deadly fumes when heated up. We have checked stores such as Home Depot, and Lowes, but neither one has what we need. Does anyone know where (and if), we can get non-galvanized steel pipe? Any help is appreciated, thanks.

How can you prevent Galvanic Corrosion? Answered

My parents bought a new green heater they've had repaired by 2 different guys in the past 2 months. The last one was a guy my brother knew; he said that it needed to be sanded, which I thought was a bit strange. It's beginning to act a bit funny again, kicking on, then going off. So I opened it up today, thinking that it was probably Galvanic corrosion from the way he talked. It seems as if a few companies are getting a bit careless in there designs. :-) So I opened it up and there was still corrosion laying on the bottom of the case from the first fix. He didn't even know what I was talking about. I read the Wikipedia article: Galvanic Corrosion. They mostly advise electroplating, which could get a bit labor intensive in this case. From what I understand, the idea is to separate the base metals, the anode and the cathode, from the electrolyte. In this case, it's the water vapor in the air. Wouldn't it just require some type of heat resistant coating to act as a barrier against water? Like some kind of spray on coating?

Advice for a hand crank ice cream maker please? Answered

I'm thinking of making a hand crank ice cream maker using an old hand drill I had and mounting that on a plastic bucket that'll be my ice bucket, then using some copper pipe I have lying around and soldering a dasher with some oak scrapers for the side. The main hurdle I'm hitting is where to find a canister for the actual ice cream. I'm wondering if I could safely use galvanized ducting, I'm planning to make sherbet on this as well, so will the acids react with it at all or is there some other hazard I should know about using ducting for this?

Where can I get screws, nuts, bolts and other hardware most cheaply? Answered

I'm planning to build a car-top bike rack based on this gentleman's design: http://www.angelfire.com/vt2/tommymc3/BikeRack.html As I've been pricing materials, I'm pleased to find that the wood, pipe, tubing and conduit will cost me only about $20. I'll need to buy one tool (a rigid backsaw) for about $10.  I was hoping to get away with less than $100 out of pocket for a rack to hold four bikes, but then I hit the screw aisle. Picking out machine screws, nuts, and wing nuts for the uprights and jotting down prices, I hit almost $10 for those items alone.  Then I looked for galvanized angle brackets to attach the uprights to the base, and those plus the screws, etc to attach them were close to $35!  Once I started looking at U-bolts and other things I'd need to put the whole thing together, I got quite discouraged. So, is there a place to go where I can get those kinds of things at more of a discount?  I tried McMaster/Carr, but they sell only in bulk quantities.  Once I'm an old established tinkerer, I'm sure I'll have a workshop full of hardware bits that I can make work, but for now, I'm flummoxed.  Suggestions? Or am I just "screwed"? :-)

bicycle, bicycle trailer, pram and fortunate events...yay...

I will try and get some photos but alas, I have only a web camera. We had a German guy live with us for a 14 months and he left me his bicycle, and for NZ$50 which was great it has 30 gears, he left us 2 months ago. I picked up a pram and a little thing like a hamper trolley with no basket on it from a rubbish pile during an inorganic rubbish collection and the pram had single hooked handles. I picked up some galvanized tubing from a rubbish bin...I asked the worksite foreman could I look through the rubbish bin 9 moonths ago...I think thieves dump stuff in worksite rubbish bins...um, I came to Instructibles after browsing computer forums for 4 years...yay, I am here...and I saw the articles about the bicycle trailers and realized I had a bicycle. I can add so put 2 and 2 together and came up with 1 1/2 so went to work and built a bicycle trailer. It took me 2 hours maybe 3 and it works great. I am so pleased, I have an idea to offer computer and computer peripherial cleaning as a local service and the bicycle trailer may come in hady for pickups and deliverys and I have already practiced using the trailer to transport repaired LCD monitors to the PostShop after I repaired them, and how lucky I was for to get them repaired, phew...I am so happy...and...Jesus loves me...or from what I remember of Him he loves me...
