Benjamin Sheridan EB from .22 to .177
« on: January 04, 2019, 10:01:45 AM »
Is it just me or are there others out there like me? I mean does any of you guys just love the looks of a weathered/cheaply moded Frankenstein looking gun or am I alone in this?
Now don't get me wrong I just love nice looking guns with their shiny deep blued steel, with mat furniture that just compliments the beast that it is holding (look at that my mouth is watering), but nasty looking guns do have a place in my heart too. I love the ugly looking guns that are very capable, I think they are the wolf in cheap clothing.

Anyway, I bought two Benjamin Sheridan EB series guns a few years back; one in .177 which was brand new, and the other one was .22 which was used and in pretty bad shape. The seals where of no function actually they were pretty dry and chipped away when I tried to remove them.
I got both of them in working condition, the .177 is just sweet. But I didn't like the .22

What struck me the most is how different both valves are, the valve on the .177 is very similar to a crosman 2240, but the .22 Sheridan had a soldered valve type. Judging by the sound of the two pistols I could tell the .22 had a stronger power plant.

For many years now I've wanted to do something with the .22 gun but never came around to actually doing it. I wanted to convert the .22 to a .177 and use a longer barrel to get the most out of that CO2. The problem was that where I live, I can't find barrels, and won't be able to purchase them online. Anyhow I managed to get my hands on a complete piece of junk break-barrel springer that was in .177, I think was a Turkish made gun. I salvaged the barrel and was left with the problem of bringing the OD down from 15 mm to 9.75 mm
Turned the barrel between centers holding on it with a lathe dog from the chuck end, managed to do a decent job on most of it but I was never able to support the center part to prevent chattering. I threaded the business end of the barrel and put a half assed crown on it (the crown is pretty good but I didn't chamfer the end of the barrel, wanted to do a 11 degree chamfer but forgot)

I de-soldered the .22 pistol, compared the two probes, the 77 and 22 so that I can make a sleeve to fit in the pellet tray. Made a transfer port, soldered everything together (I had my fingers crossed cause I wasn't sure that the solder will stick to the steel barrel, but it did). Cleaned up the pellet tray, reamed the probe end of the barrel so that the pellet slides nicely till it engages the rifling, the transfer port was a bit too proud as well so that took care of it. Made a silencer from an old printer drum which made the gun super quiet, I mean mouse fart quiet.

Now I'm left with the question of what should I do next?
Clean everything up, remove the old paint, polish the brass, the barrel and blue the barrel with some cold blue I have laying around or do I just keep it looking nasty the way it is?
Make a stock?
