Back in October I made a marshmallow shooting crossbow following the video and plans posted by Steve Ramsey on his website Woodworking for Mere Mortals. I followed the instructions exactly, but didn’t really like that the trigger and firing pin were both just tied onto the body. So I made a few changes. The first was to make the body wider at 1.125 inches. Then I created a mortise in the body and extended the trigger to slide up into the mortise. A brass rod was used to pin the trigger in place. Due to the rotation of the trigger, I had to widen the hole that extends through the body for the firing pin at the base to allow for a smooth action. I tried a few concepts to pin the firing pin in the trigger, but they just weakened the trigger. So I stuck with tying the pin to the trigger. I ended up making three more for Christmas and they have been a lot of fun. I am surprised at how far the marshmallows shoot.

Where do you put the marshmallows and exactly what flings it off? I assume the rubber and but it looks too thin to do the job. Looks like fun to take on camping trips!

The marshmallow sits under the little bracket and is flung forward by a piece of paracord that hits the marshmallow right in the middle. The elastic is theraband that is looped through the crosspiece and then tied onto the end of the paracord. Steve Ramsey’s video explains it all pretty well.

Oh yeah! We had marshmallow wars all Christmas Day at our house.
These are a blast. Check out Steve’s video. They are a fun build.
I like your trigger idea. I had thought about the same thing but went with the original plan. I used CA to glue 550 paracord for the trigger pivot.
Thanks for posting this Aaron!

Those look great Gary. Do you like the thin body?

It works fine. They’re about 7/8” thick. Used what I had in the shop.
I like your laminated body. I’m sure it made making the mortise for the trigger hinge easier. I was going to try to mortise mine out on my mortiser but time was tight (Xmas looming) and went the easy route.

They look like fun to make and use.
My grand sons live in “Nancy Pelosi” land and if they showed up in public with one they would probably get put in Jail and even worse if they were semi automatic with clips over 10 shots. LOL

you can use the nerf bullets too they fit as well! Good job and a big thanks to Steve Ramsey and I think Carmen Salamone for sending him the plans!

Really nice! I’m really looking forward to making these for my son and I.

It’s hard to tell from the photos, but I wonder if the two glued-on slides (added to create the channel for the marshmallow) couldn’t instead be extrusions from the laminated sides? Or just a channel cut into the lower piece? I’m not sure how to cut the channel in a single piece, but if the laminated sides were cut higher than the center…. I wonder.

@jdenham – go for it! I added the side laminations because I wanted a thicker grip and a little more room to hold the mortise. The slides also raise the rubberband up to hit the marshmallow near the center instead of near the bottom. I just cut the grooves for the slides using the tablesaw before the cross-arm was installed.

Have your say...
