water wagon

admin

This is my second project since starting to weld so be kind please.  It is addicting!cutting stock for wagonThought I would try coping with plasma, with alittle help from the grinder it turned out ok.fitting wheels, changed from bolts to an axlewont have to hunt a pinalmost done.I have since added a hose reel and some extra angle to hold the hose off the ground.I fill the tank half full of water and put 20lbs of air in it and I can water plants for a while.  It has come in handy controlling fires too.

Reply:Looks nice. I like the coped joints.I was wondering about two points-Is it safe to pressurize that barrel to 20 psi?Does angle twist or bend noticably where wheels attach ?

Reply:just a thought since you pressurize it, the tank direction wont matter, so turn it around. This allows to have a shorter hose so it doesn't get caught in the wheels and allows you to stand it on end when not in use or for filling.. My 2 cents worth.. for what its worthMiller thunderbolt 250Decastar 135ERecovering tool-o-holic ESAB OAI have been interested or involved in Electrical, Fire Alarm, Auto, Marine, Welding, Electronics ETC to name a just a few. So YES you can own too many tools.
Reply:Oh another reason it will protect the hose assembly for when someone forgets what their doing....like backing up and stuffOh how are you attaching the tank?? a ratchet strap perhaps? If you don't attach it it will just roll off when full.Miller thunderbolt 250Decastar 135ERecovering tool-o-holic ESAB OAI have been interested or involved in Electrical, Fire Alarm, Auto, Marine, Welding, Electronics ETC to name a just a few.

Reply:I've pressurized full oil drums before. I put the air pressure (through a regulator) into the 3/4" port. In the 2" port, I've got a standpipe that screws in there and goes to the bottom of the drum. Attach the standpipe to my overhead oil storage with a chunk of 3/4" hose and start turning up the air.I typically run around 7-8 PSI. takes about 40 minutes to empty the drum. This leaves about 10-20 liters left in the drum which I have to pour out. I've had the ends bow out, but never pop open - this is on steel drums.A neighbour goes up to 15 PSI when emptying his oil drums, but he has popped the ends open.For a plastic drum, I'd keep the pressure down to less than 10 PSI. Maybe a better idea would be to use a old 100 LB propane bottle that isn't worth getting re-certified again?Andrew
Reply:I have been using this drum for 2 years now without any problems with the pressure.  As far as filling it I made a hose with 2 female ends and just hook it up to the faucet.The frame is in the way to turn it around.  My problem has always been getting in too big of a hurry!  I have this one sold to a buddy and I am going to make a new one that is wider so the tank fits down in better so I dont have to strap it in.The angle is all 3/16, there is no flex, I did use a 5/8 rod for an axle other than the bolts.I reduced on 2" hole down to 1/8 and put in a sniffer valve and use my compressor to put in air.Thanks for looking and the coments.
