Craig Tallant Posted August 5, 2015 Share Posted August 5, 2015 (edited) This is going to be made from a Sink I obtained for free .. the post cap was 2 bucks and the wood ash, sand ( red sand from property.. natural) and kitty litter are from property ( or house). Frame will be from sign holders ( the metal ones you see in yards of houses for sale) fits sink perfectly and will cut and weld to make legs and support. Could use lumber from property also .. either way its free stuff.. woo hoo. So hit me with your comments ..am I on the right track? Yes I know I misspelled sink..lol and the firebowl will be formed from the clay. No brake drum etc. Edited August 5, 2015 by Craig Tallant addition Quote Link to comment Share on other sites More sharing options...
Charles R. Stevens Posted August 5, 2015 Share Posted August 5, 2015 Most of us can only forge 6" so a smaller ducks nest might be in order Quote Link to comment Share on other sites More sharing options...
Craig Tallant Posted August 5, 2015 Author Share Posted August 5, 2015 K .. that's easily remedied .. What topside diameter would you suggest .. 6-8 inch? Quote Link to comment Share on other sites More sharing options...
Charles R. Stevens Posted August 5, 2015 Share Posted August 5, 2015 Yes sir, and only 4-5" deep Quote Link to comment Share on other sites More sharing options...
Craig Tallant Posted August 5, 2015 Author Share Posted August 5, 2015 I remembered a conversation you had and spoke about using a bullet tuyer ( or something like that) .. the impression I got was something like what I am doing .. Its a post cap about 1/4 in thick I believe.. Will it be okay to use galvanized steel for the piping underneath .. Quote Link to comment Share on other sites More sharing options...
arkie Posted August 5, 2015 Share Posted August 5, 2015 (edited) Is your cap steel? If so, soak your galvanized cap in dilute muriatic acid for a few minutes or vinegar overnight to remove the zinc. A lot of those caps are aluminum and not good for a tuyere, and the acid will eat them anyway. The piping underneath usually doesn't get hot enough to be a problem. Use regular black pipe if you can get it, instead. Edited August 5, 2015 by arkie Quote Link to comment Share on other sites More sharing options...

Charles R. Stevens Posted August 5, 2015 Share Posted August 5, 2015 I dont know how long the weld cap will last but a single 3/4" hole in the center should be enugh. Leave the cap proud so slag will roll down around it. Quote Link to comment Share on other sites More sharing options...
Craig Tallant Posted August 9, 2015 Author Share Posted August 9, 2015 Well I have all the piping put together, used all black pipe .. I am wanting to keep the existing nipple that leads from the sink drain down .. I have a reducer since it is 1.5 inches and I am using a 2" pipe for the rest of it. Is that okay? I could not see a problem with it since it is only about 2-3 inches of pipe at 1.5" that opens up to a drain that is about 3" in diameter does anyone think this will cause complications?

Charles R. Stevens Posted August 9, 2015 Share Posted August 9, 2015 Should be ok, you could of saved a bit of coin by going 1 1/2" from the sinc botom tot he blower and just set a 2" niple and cap in the sink dran using adobe to seal it up. But 2" and a reducer is fine. Blowers usualy make more air than you need, bellows are sensitive to restrictions and friction Quote Link to comment Share on other sites More sharing options...
