Hey there, let me start by saying I wasn't sure where to post this but since some of the same principles apply to making rifles, I put it here. As the title implies, we are going to make skis today.
I start with 4 strips of sheet styrene, 2 thick and 2 thin, cut the full length. I make them wider than needed so there is room to work. Cut the styrene strips to different lengths because the skis will be longer than the sheet of styrene allows.
I take a piece of wood and with a jigsaw cut the curve of the ski into it. This will be used to form the ski.
Glue the strips together, but only where the plastic is touching plastic. You want there to be gaps for the tail end of your ski.
Now quickly, while the glue is still wet, compress the future ski between the 2 pieces of wood. With the glue still wet, the pieces will slide along each other into the curved shape.
It helps to have a second pair of hands for this, but it can be done solo. I use rubber bands to hold the wood together, but a large enough clamp will work. Let it dry for a day or so, just to make sure the styrene has bonded.
The glue has dried, and you have the curve in the ski. Model glue works because it doesn't glue the styrene together, but melts the plastic together. Don't be afraid to use a lot.
Now you need 4 more pieces of styrene, once again, 2 thin and 2 thick. These will be shorter, as you just need it to finnish the tail of the ski. They will also be of varying lengths. It's OK to make them longer than needed, since you don't want your ski to come up short. Slide them into place and secure with glue.
Now I draw out a pattern on paper and cut it out. I use white glue to glue it to the styrene because it cleans off the plastic easily.
Using a Dremel and a cutting disc, i cut off the excess styrene. Protect your eyes with safety goggles.
Once cut out, it's down to filling and sanding any holes or lines. For the raised areas for the feet, I took a short piece of the thick styrene and placed where the feet would be. Then I took a longer piece of the thin styrene and placed it over, gluing it in the center and at the ends. Once again, fill and sand the seams smooth. I used Mountain Troopers tutorial in painting rifles to get the wood grain effect and here it is, the finnished product.
You'll be able to see the skis on my Turkish ski trooper, which will be posted in the next day or so. If you've got any questions, I'd be happy to answer them. I hope this gives you ideas of your own, and they don't have to be about skis. The first time I used this technique was to make a recurve bow, so you're only limited by your imagination. Thanks for lookin'.
