For me it's actually an addition to my 3-Way Sound System.
I needed something that could help me transport my soundsystem. I was looking for bicycle carts on the internet, but I only had a very low budget.
So I took a good look into my backyard, and there I found a easy solution to my problem. The main two ingredients are: a table and a shopping cart.
(The shopping cart is easily replaceable for any type of D.I.Y store wheels.)
Step 1: The Main Ingredient
-Set of wheels (I use the wheels of a shopping cart)
Step 2: The Wheels
Dismantle the wheels of a shopping cart:
-take of the actual wheels (pic.1)
-take of the suspension (pic.1,2)
-take of the ring where the suspension was attached to. (pic. 3) This can be pretty tricky because the ring is welded to the arm of the cart. Use a grinding machine incl. some protection for your eyes.
Step 3: The Table
Step 4: Attach the Wheels to the Table
Drill a hole in the wood to make a little room for the bold of the suspension. Make the hole just a little smaller than the actual bold is.
Use super glue and screws to attach the ring.
Repeat this on each table -leg.
Now attach the suspension with the original bold. Don't go to far with this, you might crack the wood.
Attach the wheels back on the suspension.
