poor, poor, PST
on: June 30, 2012, 11:13:58 PM
Thanks to Gareth I have a subject for this thread!

I bought a really bad looking PST on ebay last week and it needs a lot of attention to bring it back to...collectors condition.  It currently is in trash collector condition let's hope for something better.

Bob and Dunc, if you think this thread might be under a different category please do not hesitate to move it.

First let look at what we have to work with:









Interestingly it seems to be in decent condition other than the rust.  The milled awl looks good and the blade is in great shape.

So the first thing that this tool needs is something to stop the rust.  So into a penetrating oil dip, the jar that I put the tool in has a mixture of WD-40, PBlaster, Kroil Oil, CRC Marine and who knows what else.  I think this one will stay in the dip for a few weeks.  I leave the tools in the sun so they get hot and it cools off at night so there is good opportunity for expansion and contraction.  The jar has been in the sun for a few hours and I expect it will get a little hotter than the reading shown on my temperature gun.

In the dip:


You don't want to touch the tools after they have been in the sun for more than a minute:


Suggestions on how to clean it up are appreciated.  Keep in mind I have a really nice ultrasonic cleaner for the next steps.

More to come.

That's in a sorry state Bruce, although it looks like it might just be superficial on the parts we can see. My main concern would be the pivots - but then again, it seems to open OK.

Sparky415 is our resident Rust Master, so don't know if he'll have any suggestions. If it were me, I'd probably strip it right down and clean the parts individually with wire wool. Actually that's not quite true. I'd personally put it to one side till I found time, by which point it would have all but dissolved  :rofl:

Okay, maybe I'm from a different school of thought. I think this thing looks like an opportunity waiting to happen.

I got a work horse PST from Captain Spaulding, and LOVED that it had some miles on it. Honestly, not as rough as this one, but still, it had paint all crusted up inside a few of the tools. It was the perfect excuse to take apart and fiddle with the workings of a Leatherman without fear of messing up a shelf queen.

It really looks like not too much effort should bring this thing back into pretty darn good shape. Maybe not ever as a collecting piece, but I threw my PST into my range bag. It's going to work for a living! :D

Look at some of the miracles Sparky415 has done in the Car Boot Finds thread, if you think this thing's in rough shape.
http://forum.multitool.org/index.php/topic,20179.0.html

I'm eagerly looking forward to seeing you bring this thing back to life!

It is a riveted Japan PST or it would already be in pieces.  The tools all surprised me and opened quite easily.

The expansion contraction idea sounds like a good one Bruce  :salute:.
I am keen to see how the plier pivot comes up & the tricky bits under the rivets + the areas you can not physically get into  :think: :think:. If it was knurled fastener PST would you have pulled it apart Bruce  :think: :think:
I wonder if anyone has ever drilled out the rivets on one of these Japanese made PST's  :think: :think: & retro fitted alternate fasteners  :think: :think: probably a sacrilegious thought & more trouble than it is worth :think: :think: :D :D

The stake marks found on the riveted PSTs plier pivot may be a hinderance(for initial rust) & a help(getting lube in & crap out)  :think: :think:

Hi Mat,

I have thought about drilling out one side of the rivets and putting in "stock" PST pivot screws.  I have a nearly mint Japan PST with hollow rivets that has a broken awl.  So I have thought about making new rivets but that seems like a lot of work that could easily end with a tool that will not open. 

I have opened up many a PST so if it would have been knurled fasteners I would have opened it up without a second thought. 

I think the stake marks are a really neat opportunity to get lube into the plier pivot.

If the rust gets loosened up and turns to crud the ultrasonic cleaner will get it off the tool.  Maybe a couple of cycles between the dip and ultrasonic? 

I will take it out of the dip tomorrow for inspection.

Yeah, I hadn't caught that it was a riveted one. I'm honestly not familiar with the Japanese variant, and guess I'd jsut assumed all PSTs were knurled nut construction. Still happy to see how it goes and wish you the best of luck in its recovery. :D

Good thread title Bruce. :D  Looking forward to seeing how this comes out.  As you can't take the pivots apart I guess the best I could think of would be to attack them with a toothbrush.

Ok, a quick update.  I went outside this morning and took a look at the tool.  I should have tried to take a picture but I didn't.  The tools are on a table on our deck and if you walk between the house and garage you pass the jars of dip.  I shake the jars occasionally when I walk past just to agitate the tools.  When I saw the Japan PST this morning it looked like it was covered with dirt, all the junk floating in the dip settled and a bunch was on top of the tool.  So I got it out and wiped it off for a few pictures.  Also, I noticed that the tool is soaking in Kroil Oil which is a really good penetrating oil.  Expensive and smells like fish but it really works.

This side looks much better now:


The word that was written (Robinson) in blue permanent marker was on this side, unfortunately someone ground this side before they wrote on the tool:


Opposite side 1:


Opposite side 2:

 
The markings on the blade tang are somewhat visible now:


Sorry about the white balance, I did not set it for the lower light this morning and the tool is already back in the dip so....

Gareth, It was very much appreciated that you came up with the thread title.  I was trying to figure out what to use when I read you message.

So much sooner than I thought the tool might be ready for the ultrasonic cleaner!

Since the PST did so well overnight in the dip I decided to put a little more time into it.  Plus, I am not leaving on a business trip this week so no leaving for the airport today.

I am very lucky that I have a Scotchbrite wheel exactly the same as what they use at Leatherman.  I saw one sitting on a bench when we went on the tour at Leatherman and asked the guy running the grinder what grit it was.  So I bought one and the adapters then I needed to find a good used 8" bench grinder to power the wheel.  So it did a great job of cleaning up the one handle.  I have always been disturbed by people cleaning up a Leatherman tool with a longitudinal stroke, the factory used a up and down stroke that looks very different that left to right.  The blade on this PST and the grinding on the handle were both left to right.  It looked like someone used medium sandpaper on the blade, so I touched it up a little on the Scotchbrite wheel and attached the handle that was ground. 

Here is the tool sitting in my ultrasonic cleaner before I put in water:


I put in the water, detergent and vinegar (my cleaning mix) and the plier pivot looked like it was smoking:


That is dirt particles being driven out of the plier pivot, I was lucky I still had the camera in my pocket because it did not last for more than a minute.  Here is a closer shot of the pivot:


It looks like just a dirty spot starting at about 3 o'clock on the pivot but it is stuff rising from the ultrasonic.  There is a little still coming up from 9 o'clock but it just about ended by the time I got the picture taken.

So it looks like I have some play time today on tools.

Thanks Sparky and everyone who has commented.  I thought this project was going to take quite awhile but I am over 90% done.  Some touch-up remains and the blade needs sharpened but it might be awhile before I dig out the Dremel tool so here is yet another update. 

I rinsed the tool with hot water out of the ultrasonic because the vinegar is a acid and while it brightens the tool it also will cause it to rust.  So after a quick shot of air here it is:


Other side:






Finally the closed shot:


It's not perfect but not bad.  I need to blend around the one rivet on the LEATHERMAN side and some minor clean up remains but it really came out better than I expected.  The file is what really surprised me, usually the file requires some work with the Dremel tool and a small wire brush but the file is nearly perfect. 

I'm going to spray it with some CRC Marine 5-56 and put it in a clean jar to soak for Leatherman brown prevention. 

More when I get around to working on it some more.

I realized this is a great place to use Christian St. Clair's Nano Oil!  I have used it on tools I want to keep so I put a small drop on every pivot and will put it back in the sun.

Nice Job! :cheers:

The finish is actually easy when you have the exact same Scotchbrite wheel as Leatherman!  My wheel needed to be dressed or I would have gotten a more matte finish.  But I thought the shiny might look good and it turned out to match the other handles when it was cleaned in the ultrasonic. 

I actually had a couple of jars soaking in Marvel Mystery Oil for the past 3 or 4 weeks so I decided to open them up.  I found 5 more Japan PST's, a Pocket Survival Tool, 2 PST's, 2 Surges, and 2 blunt nose Gerber 600's.  So since I was already dirty....

The one Surge was sold to me cheap for parts because it would not close and the outer tools would not open.  I pried all the internal tools open and the Surge closed!  The outside opening tools opened easily and other than being dirty they seemed pretty good.  I looked closer and it seemed like the internal tools would not go all the way down, looking a little closer and cheating by comparing to a good Surge I realized both handles were assembled backwards.   So as soon as I get a chance I will take it apart for a complete rebuild or I have been thinking of a Recharge...maybe one with scissors and a saw/file exchanger...I wonder if the Surge awl will fit in a Charge?
