I have a pair of Walker-Turner drill press table legs.
Pretty thick

lead paint.

Have tried two different spooge tank setups over the last two days and it didn’t do a damn thing. I’ve had great success before with this method on a patternmaker’s vise, but I think it’s too big with too many surfaces and I can’t get the “line of sight” unless I try a third, vertical tank. Too frustrated with this method.

Heat gun? Chem strip?

The goal is to strip to raw cast iron and leave it that way. They’ll be used indoors as a kitchen island base, paired with a Maple top.

I want to finish these legs by Sunday. So either find a way to strip them or just repaint.

The leg on the right was in a spooge tank for over 8 hours surrounded by 4 pieces of rebar. Basically did nothing.
Leg on left was wire wheeled. The backsides are completely covered and hard to get into all the recesses.

Any advice is appreciated.

Thanks!

Can you sand blast them or have some do it for you? That would leave a very clean surface while maintaining the cast surface with minimum change.

Media blasting.

Cheers,

PS: I’ve never had good success with rebar in an electrolysis tank. Not enough surface area.

I can look into sand blasting.
I remember when I was trying to decide what to do about my vise I looked into sandblasting and got a quote of $160.
I imagine these legs would be much more.

Maybe if I redo the tank with larger pieces of steel anode it would work? Such a hassle though.

Thanks

I can’t imagine anyone charging that much to media blast a vice… or how they could get away doing so. You could also look around your area to find companies that will powder coat, chrome and anodize stuff, as they usually have a large dip tank that will strip to bare metal (and some will blast as well). I doubt they would charge much just to dip a couple of pieces for you. You could also use a chemical stripper yourself, but I personally hate that stuff and the mess it makes.

As for the electrolysis – that isn’t the best way to remove paint, just rust. While a lot of times the paint will come off as well, it depends on the paint and how much rust was under it. Sometimes it will remove most or all of it, sometimes it won’t even touch it. If all you are looking at doing is remove paint, it’s best to look at other methods IMO.

Cheers,
Brad

I would use a wire-cup brush on an angle grinder.

What he said. Grinder, wire wheel. But personally I would leave some of that finish on there. It looks old, not like a new casting.

Maybe try a propane torch?

Yikes, over $160 seems absurd to me, I was thinking like $20 each on the extreme high side.

What’s wrong with using a chemical stripper? Wire brush or scotchbrite to get all the paint off and then “even” the finish.

For finish what about gun blue? Be a bit expensive and not as durable as paint though.

Paint them a greyish silver. Will look like bare metal but won’t get rusty (they will rust if completely stripped).

DO NOT do anything to create lead dust. The dust gets airborne and goes everywhere, especially into your lungs. Look up the MSDS for lead. This is why media blasting is so expensive. After they blast your parts, they will have to do an extensive clean up and dispose everything at a Hazmat facility. Use chemical stripper and clean everything well.
Collect all of the residue and dispose of during a hazardous material day at your local trash facility.
Just a word to the wise,
