here is how to make an awesome tech deck ramp that should cost you less than 10 bucks!!!
Step 1: Materials
You will need:
1. A LOT of plaster.
2. spreading tools for the plaster
3. chicken wire
4. cardboard or newspaper(cardboard is better)
Step 2: Making It!
To start you need to shape the chicken wire into whatever shape you want and start putting plaster over all of the wire. The plaster will fall through and that is ok, but later if you are running low you can just scoop it out and reuse it. You should make a fairly thick layer of plaster because this is what you will be riding on when it's done. There is no doubt that this will take a long time so be calm and don't get frustrated.
Step 3: You're Almost Done!!
Depending on what kind of plaster you got it should take about 10 to 24 hours to dry. You should check on it every once in a while and fix the cracks in it so your tech deck doesn't get stuck.
I got some comments suggesting that you should sand the entire thing down. I haven't tried it yet but feel free to and comment me with how it looks. Another option that my dad suggested is to paint over the cracks. I didn't try it so I am not sure if it works.
