Hi - long time reader but first real question. I'm finishing up an early 603 XM build and I picked up a clean, but used, Edgewater for it. I may drop in a modern buffer for general use but do want to try out the Edgewater occasionally for the total 'effect'.
The buffer is in very good external cosmetic condition and when assembled, the cap has maybe 1/8" of free play. This is the only Edgewater I've ever handled - how can I tell if the internal springs are shot/worn out? Not sure how much those springs contribute to the overall buffer action but didn't want to take a chance on damaging anything in case those springs are worn out... but I also don't want to 'spring' another $100 for a set of replacement beveled springs from Numrich if it isn't necessary. I assume somewhere there is probably a minimum 'spec' length for the stack of springs? Anyone ever see such a thing? While I'm at it - what type of lube is used inside these things? Seems like some type of graphite-heavy anti-seize (although I thought graphite was a no-no near aluminum). At least my springs show no sign of corrosion and weren't bonded into a 'lump'. Thanks for any help guys! |

The closest specs I've been able to find are for some spring rings just slightly different than the originals. For the stack with .815 OD and .510 ID. The maximum compression is 1753 lbs. and the recoil force is 1301.
Personally, I wouldn't be afraid to shoot your Edgewater on occasion. John Thomas |

At least my springs show no sign of corrosion and weren't bonded into a 'lump'. It's more likely a molybdenum based dry lube. A modern version is Perma-Slik which people use to refinish magazines because it's close to the original dry lube film that was used as a final coating. As you said, graphite and aluminum are a no-no. |
| It looks like the interior of the buffer cap may have been coated but inconclusive on the bevel springs themselves. There was some type of greasy coat that came off on my fingers like graphite. No way to tell if that was original though. Heck could just have been powder residue and oil/grease but I dont think so. |
