I bought a box of about 50 older gargraves switches for 20 dollars.   They honestly need work.  A lot have surface corrosion which I will have to take care of. 

Once cleaned up, will they be serviceable?  I know they aren't Ross but for the price I couldn't resist.  20200419_152722_HDR20200419_152725

Those look like an earlier generation of Gargraves switches from the 50's or 60's era as the switch frog uses a movable plate and not rails. I call them Gen 1 switches and they aren't as good as the Gen2 (hollow rail) , or Gen 3 (solid rail) designs.  I believe that they can be made to work but for mainline work on PW/MPC Lionel but the width and location of the pickup rollers may present a problem on these especially with later model O gauge trains.  I would test with the equipment that you intend to run. If that doesn't work out they can always be used on sidings used for effect but not operation.

The switches Bob shows are generation 2 not the gen.1 Gargraves Closing Frog switches.  See photos,  Gen I  closing frog,  Gen 2 swivel points, and O-100.  The Gen 1 switches are made from both solid rail, the part which pivots, and hollow rail, the rails fastened to the base. In spite of the less than prototype appearance the Gen 1 Gargraves switches do when properly tweeked work very well and have one great advantage. You can run two rail trains with scale size wheel flanges through them.  All these early Gargraves switches are sort of  O-72 though all the turn takes place in about 6" they give some long wheelbase steam locos trouble.  All these early gargraves switches work very well when used in a yard with small locomotives.  If you want to run larger locos the O-100 switches are the way to go.   In my photos notice that all the arc occurs in a short span on the gen 1 switches where the arc runs the length of the switch on the O-100 Gargraves switches.         j

The newer type with solid metal points are much less troublesome.  While most of the pre 1990 ones with the sheet metal points have been relegated to yard service on my layout, I still have some on the main loops.  Some work OK, some give me problems with occasional derailments.  I have a few crossovers with limited space between tracks.  The Gargraves switches can be modified to reduce the distance between adjacent tracks.

So.  I decided to see what would happen if I took one of the most rusty switches and soaked it in vinegar for a couple of days. 

After I soaked it, I rinsed it off with a brush and some baking soda.  Then I used a sanding block to polish the top of the rails and then sprayed it down with wd40 and wiped it down.  

The top picture is one of the other switches that was almost as bad as the one I soaked .  I forgot to get a pic of it before I soaked it but it was in very slightly worse condition.   The bottom picture is of how the finished switch looks now.

You can see how the vinegar ate away all the paint on the points and frog but honestly, i'm not worried about that at 40 cents a switch.     I think it should be plenty usable now. 

I am going to try to restore all of the rusty switches like that but use Evaporust or CLR which hopefully will be much quicker.  Then I will have a lovely stash of ready to go restored switches when I finally setup a layout someday.  

Even if I don't use them now, I do want to restore them so the rust doesn't continue to eat away at the switches.  

And mind you, I only have like 7 or so of the extremely rusty switches like above.  The majority of them are not nearly as rusty, they have more bits of surface rust but will probably take to cleaning much better.   

I just wanted to start off with the worst example to see just how far I could restore it.

Try soaking them in a mixture of oxalic acid and water. Oxalic acid removes rust but wont harm metal or paint.You will have to try different strength levels .Rinse with water after soaking.

The only issue I have with using the Oxalic acid is that I am not to interested in preserving the paint on the frog and points.  The reason being is that the rust is significant enough that if the acid ate away at the rust but left the paint behind, there would be a lot of discoloration anyway.  Now I end up with clean looking metal with no paint rather than splotchy looking paint.   

I might try that for the switches that don't have much rust on them though.

You did a real great job cleaning up that horrible looking switch.

Good find and good job! 

One problem with using an acid to remove the rust is that the rust has made millions of tiny crevices that will have two negative effects.  They will re-rust very easy and all the tiny pits will cause arcing as the locomotive wheels and pickup rollers move along the rails.  If the rails were not on a plastic base you could shot peen them to help close up the pores.  Since that is not a viable option some way to burnish the head of the rails would help.  A piece of steel vigorously rubbed on the head of the rails couldn't hurt.    A clear lacquer coating on the rails web and foot or perhaps a weathered rail paint job in these areas and a burnished head. You can always run your trains everyday that is a proven way to keep the rust away.          j

I had done air brush work on switches as clean as this.  Top of rail has to be clean/bare, for electrical conductivity, sides can be detailed/painted. IMO, A suggestion. 

Air brush Painted, Model Master, Railroad Tie Brown. :

Before paint. 

Heavy cleaning, with a wire brush,  will remove galvanized plating, exposing metal, to additional corrosion, without some type of protection,  There is a time factor, value, that needs to be considered, when refurbishing, used track, and switches.   IMO.  Mike CT

So I'm finally done cleaning the switches.  Looks like I ended up with two different types.  

I ended up with about 50 decent looking switches after getting rid of any rust and dirt. 

Ended up with about 4 that were not useable and used for parts to fix other switches.  

Need to source a tiny coil compression spring for a few of the switches.  Also need to perform a little bit of desoldering of the old feed wires on a few of them.  But overall I'm pretty pleased.
