Making a guard

I am roughing out the single sided guards for a couple of knives I am making, of course the brass I have is 1/4" thick and my design calls for a shade over 1/2". Is is possible to epoxy the 2 1/4" pieces and the spacer material together for shaping, or am I going to have to try and blend these 3 pieces together without having them joined as one piece.

The Guard will look something like this when done, I hope:o

This is just a rough drawing to get an outline but I will blend everything together and round out the corners once the handle and guard are attached to the blade
 
Solder??? I've never worked with brass, but I have frequently soldered copper to stainless or copper to high-carbon for my single-sided guards.

I second "solder". Here is a (not too good) shot of two pieces of brass with a piece of nickel-silver soldered between them.

You could also use copper for a little different look.

Unfortunately a thicker piece of brass and soldering is out of the question for now, because I want to stay true to my design. I had planned on putting some .03" spacer material in between the the two pieces brass. One knife would have red black red and the other would have black red black spacers in the middle of the guard.
I think I will give the pinning idea a try, along with some epoxy. I am going to have to look around to see what I can use for pins though, because all that I have here right now is 1/4" and 3/16" brass and stainless rod. Aside from sticking the 3/16 brass in a drill and sanding it down to 1/16, I don't know what I can do for pins. Depends on what I can find at the shop this afternoon. If they fall apart while I am working on them, it will mean I have to drop the spacers in the middle idea and get a thicker piece of brass

Thanks for the input

If you can't solder, I would be thinking about drilling and tapping a blind hole for wee little screws, with the head concealed by the handle at the back of the guard.
the threaded hole and screws would help keep it together.


or

Drill a blind hole in the front guard piece and solder the pins into that end.
assemble with your spacers
peen the pins into a countersunk recess on the rear guard piece.

That way the pins hold the spacer together without melting your spacer


Aren't you surrounded by scrap bicycle spokes ?
I would be collecting those for alignment pins and/or whatever I could think of later....
(epoxy stir sticks....whatever)

Welding shops sell uncoated brazing rod in various thicknesses, great for pins.

Both excellent ideas thanks, and have the ability to do both. The only think is that I am scared to grind into the stainless spokes while shaping:o I am still learning this craft. I think I am going to try just epoxy first to get the rough shape and if it falls apart I will be off to the supply store to by some thin brass rod and drop some pins in from the back side.

I just finished roughing all the surfaces that will be epoxied with some 80 grit to give a better chance of it working. I figure if I glue it up now, clamp them and let it sit for 24+ hours and give shaping a try tomorrow afternoon, I will still have time to go out and buy the pin stock if needed when it falls apart. I could also work down a piece of my 3/16 pin stock, its not like I am in short supply of it. I picked up 12' of it for next to nothing and using 3" at a time I have enough to make 48 knives. I also have the same amount in 1/4' brass and 3/16" stainless. For a guy that maxes out at about a knife a month, I have a bunch of pin stock in those sizes I can spare a bit. I payed about 60 cents a foot for each 12' piece taxes in, and I know they match my bar stock exactly so if I over grind they wont be seen, I hope.
 
WhooHoo the epoxy worked, with no pins. I got them roughed out, just need to go in with some emery cloth and a dowel to radius the inside curves and I can do the final shaping once I get the blades back from HT
