Parker Vac Lockdown Restoration

[siamackz]

I know, this is not such a difficult restoration. But, I'm not really a Parker collector, so vacs are new to me. This was my first restoration of a vacumatic filling system and I am quite pleased with the results. Below is a quick explanation. But, you really should visit Richard Binder's website for accurate information on how to do this. Also, the videos by Pakrer51Guy are very helpful.

Here goes my notes, for restoring a vac using some household tools and materials instead of speacialty ones:

Good job. Thanks for sharing. Nice to see that you are documenting restorations done and sharing those here.

Excellent.

 

One part that no one manages to show well is scraping the old compressed sac off the inside, and how to do it well with minimal damage to the barrel.

 

I found by accident, that if putting the barrel in the ultrasonic with water and a little ammonia, the sac gets a bit brown/gray like faded black hard rubber pens. When I was not sure about getting it all, another soak made the rubber easier to see again. The soak also softened it up a bit.

 

Still, if anyone else has good tips or pictures of this step, that would be a great addition.

Hi Greenie, I simply soaked the barrel in water overnight and then used a dental pick to chip it off the barrel carefully.

 

The step with the micro mesh and simichrome I shownabove is actually to get out stubborn remnants of the sac that have just essentially stuck itself to the wall of the barbell but is not large enough to get out with any scraping.
