I work as a CNC operator on a factory, therefor this is partly made on a industial CNC machine. No pictures because: Safety.
If you dont have a CNC: Follow instructions from btking.
Step 1: Materials.
I used 2 pieces of 12mm MDF board to the sides, and melamin MDF as the bridge parts.
2x -- 1100x500x12mm MDF
9x -- 500x120x16mm Melamin MDF
I have no drawings or jigs to show off, but the .MPR file i made, can be downloadet here.
I rounded all the edges with a R6 router bit, except the pocket holes.
Step 2: Dry Try. :)
This step is just to show how it would look without any paint.
Remember dust mask if you are using a router indoor! :)
Step 3: Paint.
Raw MDF sucks to paint..! Every raw edge is primed twice, and the sides are primed once, and painted white twice.
Bridge parts was painted green/yellowish, some colour from a previous project.
I did not paint the melamin because it is super fun to slide down from as it is. Also it is easy, and satisfying to scrape paint off with a "ziehklinge". ( Ziehklinge = Scraper i guess. )
Step 4: Play.
My daughter used it as a tool while she learned to stand up.
Then as a cradle to play around in, and then as a counter for selling puzzle bricks.... and stuff...
Oh. And it is made out of 100% scrap materials.
Disclamer: If your child falls down from this awesome toy, i am not to blame. :D
