I bought my cone from Bossbuck.com I posted a thread with the link in here titled Cone bottoms for our homebrew processesors or somthing similar. do a search.. but any how.. they work great and fit right on there... I would post a pic BUT its not all the way on it and I'm embarised to say I may have ruined one of the cones I bought.

I got the 304 SS one and was trying to weld it to the bottom of a 55gal mild steel drum. NO problem other then $$$ for some 309 welding rod... I have an ark welder. Well. let me tell you if you have an ark welder and are tring to make this thing DO NOT USE IT! Don't waste your money on the rod as the Cone steel IS TOO THIN even at under 40amps!

Instead find a buddy with a cheap-o Mig welder and buy a spool of 309. This is what has to be used to get these things to mate correctly. Otherwise you'll just burn holes and glop nothing on there really.
