Hi folks... I'm reducing my SB7 into major sections so my ancient "body" can hump it down into the basement from the garage.... I've followed the instructions in the Army manual for removing the ram (no way EVER I'd have figured that out). The set screw is out... the other stuff is done but the shaft doesn't seem interested in sliding out. This is a Gen 1 shaper and I'm unsure there's not some subtle destroyable retention feature in there someplace. Is this just something you push out with a drift? Thanks..
