Title: Silver Streak with zero compression.
Post by: Wunderwerks on July 10, 2018, 07:02:21 PM
Found a Benjamin for sale and when I went to test compression there was absolutely none.  I know the market has dropped on the value of the Blue and Silver Streaks but I haven't found any representative sales.  I believe the last kit I received from Baker was about $45 including the tool but that was a few years ago.  The gun other than the seals is in really decent condition and will clean up nicely. I have no idea what to offer.  Any ideas?

Depends on overall condition. Be me, I'd start at 60 bucks. Wouldn't go much higher than100.

Original finish on the stock with virtually no damage of any kind. Barrel appears dirty like it had sweaty hands handling it for years.  How is the best way to clean the barrel?

I'd use alcohol but remove the stock first. Don't want any getting on the wood. Goo Gone also works well. Then use Howard Feed-N-Wax on the wood. Put a generous coat. Let sit over night & buff. Works great.

Got it.  Under $110.  Tried alcohol and Goof Off without much luck.  BrassO is working about the best but I can see this is going to take some time.  No serial number that I can find but I believe the date is October 1965.  There is no wear that I can find so I'm hoping that giving it a thorough soaking with something might bring the compression back around if the valve is not stuck.  Being this old it might be wise to reseal it with new right away.  Not sure what to do.  Also can't find the right size allen wrench to remove the rear sight to clean under it.

That's not an allen wrench. It's a special wrench, similar to a torx. You can buy them on line.
To get the crud off the gun, try lighter fluid on a clean cloth.
Some people have had luck with the alcohol flush. It can't hurt to try it first.

It's the pits when your eyesight goes down the tubes.  I have virtually every other chemical in the garage but lighter fluid. Is this an actual silver finish or is it nickle?

I'd suggest an alcohol flush, followed up with a dose of Secret Sauce. To me that's the most noninvasive route to go for starters.

Naptha is a good substitute for lighter fluid.

I have been polishing things with Flitz the kind in a bottle not the paste.  I have polished alsorts if things with it.  The dirtiest thing I have polished with it was an old 40mm anti aircraft shell casing. My father in-law had since WWII. It was very beep brown, the flitz made it shine like new. It is very genteel on the things I have used it on. It is also much easier then Brasso.

Ya but did you do it correctly?

Alcohol Flush

1. Remove the stock (don’t want alcohol on the wood).
2. Open the pump arm.
3. Add at least a ½ tsp of alcohol into the pump tube above the compression cup w/ the muzzle pointed up & gun at a slight angle so it's easier to pour in the alcohol.
4. Close the pump arm & let the gun sit for at least an hr with the muzzle pointed up (I place the gun in a bucket so alcohol doesn’t spill onto the floor). Bad cases should be left to sit in this position overnight.
5. Point the gun muzzle down into the bucket & open up the pump arm allowing the alcohol to pour into the bucket.
6. Cycle the gun several times & fire the gun into a white rag. Continue doing this until the discharge is whistle clean. It might take a few more doses of alcohol to completely flush out all the crud. Like I’ve mentioned in other threads, this can be quite a workout.
7. Give the gun a generous dose of oil (at least 10 drops) & again cycle the gun until no oil is discharged onto the white rag.
8. Run a few patches down the barrel to remove any excess oil & you’re done.

Great information.  I'm fairly new to the Sheridans so this is information that is critical to recovery of the shot cycle and hopefully restoration.  I'll let you know how it works out.

Resealing a 'dan is a walk in the park if you are mechanically inclined.
If not there are plenty here to send it to.... at the last resort including myself.

Alcohol is doing the trick. The plunger cup is so hard my fingernail will hardly put a dent in it. Is this normal?  There is no damage to to cup as it is smooth all around.  How would this cup be replaceable?  The plunger bore is now very clean, shows no scuffs or damage of any kind.
Before i disassembled the front of the gun, I was getting compression.  A lot of compression when i pointed the barrel down and very little with the barrel pointed up while pumping.  Any ideas?
