So when I saw a rubber band contest I instantly knew what i was going to make. An old west style rubber band gun for my son.
This rubber band gun was made with pallet boards because... Well because I really like to use pallets. Hope you enjoy this instructable!!
Step 1: What You Need
5/8 oak dowl & 1/4 dowl
Various grit sand paper
Dremel with sanding drum
Step 2: Plane and Prep Boards
Once the boards are ready, run them through the planer to get a nice even surface. Doing this first makes the rest of the job easier.
I wanted the gun to look like a rugar vaquero so I traced one and cut out a pattern. Then use that to trace the pattern on to your pallet board in two spots.
Step 3: Cut It Out
You really don't have to be perfect when you cut these two out because you can shape later. You need two pieces cut in the same pattern so you can put them together. After you cut out the pattern, cut out a spot for your trigger. I used a fostner bit to start and then a jig saw to finish.
For the trigger I looked at some pictures on line to find the shape that I wanted. When you have two pieces that look similar you can move on the some shaping.
Step 4: The Trigger Spot
Then use a chisel to smooth out the sides and your good to go. You have to do this on both sides of the pattern. Just make sure that you drill out opposite sides so they will fit together. I did not do this the first time and k had to make another piece.
Step 5: Shape Up
I started on the bench sander to even up the sides. I also rounded over the Handle and the top.
After the rough sanding was done I started with a dremel and a 60 grit drum. I did a lot of shaping with this. It worked awesome because you could really take a lot off in a short amount of time. I looked at some more guns to see what to take off.
Step 6: The Trigger (updated)
I put it in the hollowed out spot and used my finger to figure out a good pivot point. When I thought I had it right I drilled a small hole and inserted a finishing nail to act as a pivot. I tested it to make sure that it was going to release the rubber band.
I drilled through the other side of the gun so I could push the pivot all the way through.
I got a lot of comments about not having any resistance on the trigger to hold the rubber band. Luckily I am working on my second gun now and I redesigned the trigger. It was a very small change but it made a big difference. For this step you need a very small eye screw a small spring and another finishing nail.
All I had to do is hollow out another small channel running perpendicular to the first one. I use this as a channel for the spring. Then I screwed the eye screw close to the bottom of the trigger, but still in a spot that will be hidden by the body. Make sure that you make the channel long enough that you can put some tension on the spring.
I drilled a hole at the end of the channel to secure the other end of the spring. I used a finishing nail just like I used for the trigger. You want to be sure that you have quite a bit of tension on your spring so the tension of the rubber band isn't greater than the tension of the spring. It is a very simple fix and works really well.
Thanks for all the encouragement to do this spring better. I really like that way it turned out. Hope you like it.
After I dry fit it, I glued and clamped the body of the gun.
Step 7: Chamber
For the chamber I cut out a small square that was 3" by 2 1/2". Then I rounded it over on the bench sander. Then I used the dremel to make the groves on the chamber.
Step 8: Handle
Step 9: The Barrel
Step 10: Glue It Up
Step 11: Sand and Poly
When that was all done I used minwax spray poly to finish everything off. I used spray because of all of the small spots I had to get into. I did three coats and it turned out very nice.
