    Default stuck risers

    Anyone have tips for separating a riser from a log manifold? I shot the nuts with penetrating oil for a couple days, and finally got them off. The studs dont look too bad, but some corrosion is visible. It didnt look bad enough to make me think it would be stuck once I finally got the nuts off, but its stuck. I took a few decent whacks with a rubber mallet and it seems pretty well stuck. I lightly tapped a chisel between the stud end and the riser to wedge it off, no luck. Anyone know of a penetrating oil that will 'eat' the corrosion by-products away? Or some other whack location that might get these things separated?

    Get some steel putty spreaders and tap the gasket in till nothing left but the four studs. Once your to that point (keep soaking with penetrating oil) tap a couple one side than the other. It will start to losen back and fourth. Just be patient. I have removed several this way in good to bad shape and didnt have to cut or break studs.

    Anything I can do to soften up the gaskets or get them to start disintegrating?

    Keep soaking them with the penatrating oil and start to tap in at the weakest spots first.

    If you don't have the time to do the above method, saw thru the gasket, with a hack saw, take your time and damages will be minimal. Center punch the cut off studs, drill and extract them out. If any surfaces are scarred, or corroded, have the surfaces decked, and faced. This can be done in about half a day, including machining, if you have a capable machine shop near by. I've seen a great many hammered logs and risers, and they are'nt pretty.

    i was told by my machine shop heat them up as hot as you can get them and dump them into a buck of oil to let them cool totally they said used oil is fine. then tap them apart with something to spread them and tap them side to side with a dead blow. OK not that i tried it. i was told this after my endeavors. i ended up cutting mine apart.
