Using a spring compressor

[RedFeather]

Well, my JM lubes are here and I finally have to tear down one of my air guns due to a bad sear.  Now, once I build a spring compressor, how, exactly, do I go about using it?  I know it sounds like a dumb question, but, not having seen anyone actually apply one, I'm not sure what the exact process is.  I take it you run the compressor up snug against the end of the compression tube and then tap out the retaining pins?  Are the pins directionally keyed in some air guns like dovetailed sights?   And, once the pins are removed, you start to back off the compressor.  That about the size of it?

Thanks in advance from a shooter, not builder.

That's all you do. On the T-05 trigger you may have to reset it before reassembling your gun. The easiest way is to use a couple shorter pins to keep the trigger "set"if you aren't going to do any trigger work. check out Hector's pictures.

Thanks.  First up, 1928 Haenel Model I DRP.  Direct sear, won't hold now.  Next up, circa 1967 Milbro G46 (Diana 27 variant - don't think it has the 3 ball trigger).  After that, maybe, a Norica 80G entry level target break barrel, then a late 50's Diana 50 (3 ball trigger) if I can get the cocking arm stud out.  Has one of those round nuts with the two holes in it and I have to adapt a socket to unscrew it.

I haven't opened the package from JM yet to see what the lubes look like but they must be small since it came in a soft sided envelope.  Guess a little bit goes a long way.

Thanks for the info.  I know there's a trigger trick to disassembling the G46, as well.
