Default SFT Pressure

Now you've done it. With all the recent posts on rust removel, I finally got around to building a tank. The barrel was from an auction for $2. The other stuff was also from auctions over the past couple of years. I was amazed that it worked right from the beginning. Little bubbles are comping up to the top. The charger is in a 12V 2 amp setting and in at 6 on a scale of 8. My first part is a tractor seat to be mounted on an old spoked equipment steel wheel.

#1 The barrel with 8 1/2" holes for the adapters to hold the rebar.
#2 Bolts with brazed brass on the head to accept solder.
#3 Bolt with 1" deep 1/4" tapped hole to bolt on the rebar.
#4 Rebar with tabs welded on and holes to attach to the bolts.
$5 Rebar installed in the barrel.

You didn't say anything about Super Washing Soda?

A couple of old lawnmower blades will work better and last longer than rebar.

Peer pressure is strong. Glad I finally got around to making one. I have a lot of plans for it over the summer.

I only have one old blade so it is rebar for now. I used 2 1/2 cups of washing soda for 30 gallons of water. 1 tablespoon per gallon. Just checked it again and there is a 1/8" line of red stuff around the edge of the barrel after 1 hour.
I used an old c clamp with a missing swivel to clamp the wire to the seat. Guess I will get a clean clamp this way too. Had to go to 5 stores to find the washing soda. Got 2 4lb boxes.

I was wondering if I used my DC welder at 40 amps if it would speed up the process????

+1

Also easier to clean the crap off of with an angle grinder to get down to bare metal so it'll draw more current and clean faster.

Sandblasting is still faster, but this is quieter and easier, particularly for oddly-shaped large objects.

Not likely. You'd be more likely to boil off your water.
Hi amperage in small container is a waste of energy likely to do more harm than good.
You could boost that battery charger up to full amps.

Here's how much difference 44 hours can make at 12 volts & about 8 amps.
It was wire brushed by hand. Practice a little patience.

Thanks for the info. My charger scale goes from 0-8. It is already at 7 on the 2 amp setting. When I switch to the 8 amp setting it pegs the gauge. I was concerned that it would overload the charger being pegged out like that. Not to worry?????

Milo, I have used a product from Wally World called PH Plus, the washing soda is hard to find around here. I think the PH Plus costs a little more. It's in the pool section. Nice job on the fabrication, you'll get a lot of use from that.
