This is how I made a 1860-inspired Colt for my Son. NOTE: The intention was not to make an exact replica, but to make a robust wooden toy with enough details to be interesting.
1. step was to make a drawing of the pistol, cut it out and use it as a template to draw a cut line on 18 mm plywood. I Chose 18 mm plywood because it is easy, to remove one or two layers to make some details.
2. Step was to cut out the handle and half of the stock cylinder.
3. This step shows the pistol after cut out and what it looks like after I glue the handle and the cylinder parts on to the body. Note also, how I have removed some layers of the plywood to ad details.
4. After sanding I painted the pistol. First black all over so there would be no unpainted spots. After this, I experimented with a pure "iron" version, but settled with a "iron" and "brass" version.
Tool and material: Electric jigsaw, rasp, sanding paper, carving iron, drill, glue, acrylic paint, varnish, 18 and 3 mm plywood, 40 mm round stick
Time spend all in all: 3-4 hours. Have fun!
