Well i got a few minutes when i got home today. So i grabbed one of the mini kegs i got and made me a tank. I'll add pictures as attachments cause my webhosting seems to be buggie at times.
1 - I marked the oppisite side of the can from where the petcock/gas line will go. I'm putting that where the tap is at the bottom. This will put the cap straight up from it.
2 - I marked the center of the top of the keg where i will have to drill a hole for the bung.
3 - I use a drill with a holesaw that's 1-5/8 " as that's the size of the bung i'm using. This is very, very thin so go slow and use as little pressure as possible. Because it's so thin next time i'll use a 1-1/2" holesaw bit and run a file around the hole a few times to get a tight fit to the bung.
4 - I put about 6 layers of tape over the opening in the bung to keep splatter from messing up the threads. I used 2 magnets to hold the bung in place as i tacked it in 3-4 places. Now because this is very thin metal and i'm using a little mig with flexcore wire, everthing is on it's lowest setting. It's still very easy to burn through the mini keg. Also that tape is a waste of time now. To weld it in , i'm having to go so slow it's burning the tape up. So i've placed about a 6" long piece of tubbing that's the same size as the bung, over the bung to keep the splatter out.
5 - To weld the bung for the petcock i just held it in place and tacked it . Then welded it in all the way. It's about a inch or so long so i was not worried to much about splatter. I'm not going to use a petcock, i'll just use the gas on/off that's on the carb. IF you plan on using one, i would suggest you place the petcock fully in the bung. Hold it to the tank where you want it and face the petcock the way you wish. Mark the tank and the bung with a marker. If you don't then you will have no idea which way the location of the petcock on/off will be. I don't think this will matter much on a mini keg but, it would if you where making yours so it stood up and not sideways like this one. Then i think you'de want the on/off to be on the top.
The last pictures is showing the difference in size of the bung. The smaller one is the one i've used on this tank. The bigger of the two is the standard size used on a motocycle tank. I got this one from hushboys, they sell alot of their stuff on ebay as well as their site.
THis is the cap and bung i used :

It's still not done as i still have to weld a piece of steel over the hole that came in the top of the keg. Just ran out of time tonite.
I picked up 3 mini kegs off ebay for $3 w/ $12 shipping = $15 , I got the cap for $25 w/$5 shipping = $30. For the petcock bung i just used a 1/4" pipe nut or some places call them an extention nut. IT was like $0.15 or something close i just grabbed a hand full. So i'm under $50 but,,,,,I still have to clean and seal it. Which will cost me about another $30 but , i'll have enough to do all three kegs . But i'll have to do them at the same time as you can not reseal the sealer.
