Hey Guys,
Thanks for all of the great comments and ideas! Now you have opened my mind up into some different avenues. A couple of initial thoughts:
1. I guess that the whole point for me would be to do this for as little money as possible. So, the concept of rebarelling the action would be out of bounds. As Wyo coyote pointed out, a rebarrel job would quickly push this type of project into huge money.
2. I love Marlin levers, but unfortunately they all load from the side of the receiver, instead of from the top. There is nothing wrong with this, except that it would create a strange single- shot rifle, and I think this project may already be strange enough. :-) So, this leaves the Winchesters.
3. With the Winchesters, I guess you have to simply accept that you are going to be in one of the standard calibers (.30-30, or .32 Winchester, or maybe .38-55). Any others I haven't thought of? Of course, the Winchester 73s, and other black powder models came in a wide array of calibers, but as collector, I can tell you that you would be spending at least $2,000 to find one that is in good enough shape to shoot, and that kills it money wise. (Also, you would be destroying a valuable antique, for a fun project.)
4. Hey wait a minute! I'm now thinking, what about a Winchester Model 95, in .30-06. They load and eject from the top, and you could slip a chamber insert into the receiver to make it a .308 Winchester, and then figure out how to put a blocker in the bottom of the magazine so you couldn't load more than one shell? Just a thought. Maybe too heavy and complicated.
5. The fore-end? Why get fancy here? I'm thinking about the way that the forearm of a Handi-Rifle attaches to the barrel. Even if the project rifle had a standard round barrel, why couldn't I just have a bar of metal (or even a Weaver type rail? ), installed on the underside of the barrel, just in front of the receiver, and then drill and tap two large machine screw holes into it, and then use these holes for installing a forend, using large round headed machine screws? Of course, everything sounds easy until you try to do it.
6. Another fore-end idea, as already suggested, is to use a short magazine tube (with a steel rod inside) or a steel rod threaded on one end to match the threads in the mag tube hole, as a hanger? With a short steel hanger rod sticking out of the reciiver about 8 inches, you could slip a heavy forend on it, and then just secure the front of the forend to the rifle with one vertical screw up into the barrel. (Might even use a fancy nosecap).
Oh well, the only thing going for me is that there is a gunsmith just up the road, who would do the small drilling and tapping jobs for next to nothing, and my neighbor is a retired cabinet maker, with every conceivable wood shaping machine in his shop.
OK, does anyone have any guesses as to whether the metal used in the Winchester lever loop is malleable? In other words, if I cut off part of the end of the loop, and then wanted to reshape the long remaining piece into a small curl, could I do that by lightly heating the end and lightly tapping it with a small hammer on an anvil?
Thanks for all thoughts. (Clearly, this could not be a target rifle. Just a fun 125 yard big game rifle.)
