Is there a solid way to do this aside from pinning it?

I'm making a bayonet for a friend, and I want to put a full finger guard across it (ala trench knife style). Since it's going to be afixed on the end of a rifle, I'd like to use aluminum to keep the weight down if possible.
 
Wade,
We have a discount steel store in downtown Minneapolis that carries aluminum in various barstock, and so forth. Its considered "scrap"
and they sell it by the pound. It goes for 50 cents a pound. Bought lots of steel tubing for my NWG there. Great deal IMO.

eutectic has a soft solder that they claim will solder aluminum to steel. I have never tried it and have no Idea where to get it.
 
if your able to fit it together with a mechanical lock , use jb weld youd have to machine it apart id think after it had a day to set up?
 
Thanks guys!

I think I have somewhat of a game plan now. I put up some pics when I finish it, if it all works out. :)
 
you can cast it on... (aluminum melts at a little less then 1200ºF) Also you could make it so the aluminum is a thousandth or 2 over sized, and the the place it's getting fixed to is a thousandth or 2 undersize. heat up the undersized part and freeze the oversized. put them together and let them come to room temp. It wont budge!

I think most hardware stores have it somewhere near the mild steel stock. I just bought a 1/2" bar the other day from Ace Hardware. Lowes and Home Depot have it too.

Try your locally owned smalll store first! :D
