Nick Esposito Posted December 30, 2012 Share Posted December 30, 2012 Can you use galvanized pipe fittings for a brake rotor forge? Does the forge get hot enough to give you "metal fume fever" . I'm guessing that the pipe wouldn't get hot enough, but I have heard someone say that you need to use bare iron pipe. Quote Link to comment Share on other sites More sharing options...
bigfootnampa Posted December 30, 2012 Share Posted December 30, 2012 Probably the pipe areas of the forge will not get enough heat to be a serious problem. Why tempt fate though? You can use black pipe instead... which is widely available for use as gas lines. Or you can easily remove galvanized coatings with a day or two soaking in vinegar if you are salvaging pipes.

Marksnagel Posted December 30, 2012 Share Posted December 30, 2012 I use blackiron pipe simply because as bigfoot said, "why tempt fate". My brakedrum forge does get hot at the point of connection with the pipe. Check with local plumbing supply companies. What is your general location? There may be smiths nearer than you think that can help. Mark <>< Quote Link to comment Share on other sites More sharing options...
bigfootnampa Posted December 30, 2012 Share Posted December 30, 2012 Most plumbing supply houses will have it though... and they are everywhere! Not always very visible, they are known to the pros they serve. The box stores just do NOT cut it for a professional plumber! Google up local plumbing suppliers.

Charles R. Stevens Posted December 30, 2012 Share Posted December 30, 2012 If your going to use black pipe, and your planning a small forge, you may consider using a 2" into 6 or 8" bell reducer instead of a break drum for your fire bowl. I've seen one used to good effect. As to larger diameters, I live in the middle of the Oklihoma oil fields so I haunt the oilfield supply houses.

Frosty Posted December 31, 2012 Share Posted December 31, 2012 Welcome aboard Nicholas, glad to have you. If you'll pur your general location in your header you might be surprised at how many of the IFI gang live within visiting distance. The air supply piping of your forge will not get hot enough to cause the zinc to burn, think medium orange heat to braze and a bit higher to light the zinc. If the tuyere of a coal forge gets that hot you have something way more serious to worry about. Don't get me wrong, breathing zinc oxide smoke is never a good idea but unless you're sensitive to it, it isn't going to do serious damage unless you do something really outside reason. The recent event that has a lot of the gang really up about zinc smoke is the near suicidal behavior of Paw Paw Wilson. He loaded a gas forge with galvy pipe short sections, literally packed it and burned the galvy off. Two loads as I recall and even though he opened the shop doors and windows he did himself a massive overdose and on top of that didn't seek medical care when it would've done him some good. Still, being conservative where safety is concerned is a good idea. The tuyere on my coal forge is exhaust tubing, it's cheap, clean and easy to work with. All you really need is a sabre saw, drill and pop rivet set. Sure, I migged mine together but you don't need that much. What I really like about exhaust pipe is making the ash dump, simply buy a flap cap, clamp it to the bottom of the vertical pipe with a little extension to counter weight it and hold it closed. the extension can point out front so you can flip it open with tongs or whatever you have at hand.

Dale M. Posted January 8, 2013 Share Posted January 8, 2013 I can get black iron pipe its just harder to find in 2'' size at hardware stores.Get thought process away for traditional hardware stores and look at farm supplies or industrial suppliers or warehouse businesses that are plumbing suppliers....Found what I needed at local farm/ranch/industrial supplier and cheaper than Home Depot and Lowes (who did not have all I needed in stock) ...Dale Quote Link to comment Share on other sites More sharing options...
DanielC Posted January 8, 2013 Share Posted January 8, 2013 There are plumbing supply warehouses in most towns/cities. They sell everything that is black iron because that is what is used to run gas lines (Which plumbers do) for many situations. Quote Link to comment Share on other sites More sharing options...
