I had a reader suggest that I draw up a wall ride like the one that Andy Kessler was riding in the photo from last August.
I thought to myself, hey that's a pretty good idea... and I don't have one on the site now, so let's see what I can do.
This is dedicated to Andy who passed away August 10th 2009.
As with all structures here on DIYskate, you can build this wall ride any size you want. But for the material list to be accurate you will need to follow the plans as listed below.
The wood and hardware can be found at most home improvement stores. Sometimes you can find the steel there as well, I know my local Home Depot carries the coping and threshold material.
If not, check the phone book. Look up Steel, Steel Yards, Steel Fabricators, Scrap Steel & anything else with Steel in the title.
If this ramp is going to stay outside, it needs to be protected from the elements. A good place to start is with pressure treated lumber, paint and a tarp. You may want to invest in a composite material for the surface too. Such as Skate Lite or Ramp Armor.
Be extra careful when working with treated lumber though, the chemicals used to treat the wood contain a poisonous pesticide.
Gather all your materials. Start with the 2×4's. Cut all 18 of them down to 7'-10 1/2 in length. Set them aside. Below is a cut list referencing what else you will need and it's size.
|Material Cut List|
The plywood layout diagram above shows you where to cut the sides and their measurements.
Using an 2×4 that is 8'-0 or longer, drill a hole that's the diameter of a pencil about 2" in from the end.
Then measure from the hole you just drilled, out the distance of the transition radius. In this case, 7'-0. Place a screw there but don't go all the way through the 2×4 yet.
By placing a piece of your 3/8" plywood above your 3/4" sheet, you can use the 2×4 compass by attaching the screw to the plywood where shown below. Guide your pencil with the 2×4 compass to clearly draw the transition radius on the 3/4" ply.
After you've drawn the transition for the top piece, move the 3/8" ply below the 3/4" sheet and place the 2×4 compass where shown, drawing the transition for the bottom portion of the ramp.
Since you'll need two of each transition pieces, you can use the one's that you've drawn to trace onto the other. But first you'll need to make the notch cuts so the top and bottom pieces fit together properly.
To locate the notch for the bottom piece, measure out 1'-0 3/8 and mark the plywood. Now measure out 1'-6 5/8. With a straight edge, draw a line from each point for the angled notch (which should be 8").
For the top piece, you'll need to measure up 2'-2 1/4 and mark the plywood. Now measure up 2'-7 1/4. Finally, measure out 1'-0 3/8 and mark this as well as shown below. With a straight edge, draw a line from the final two points to create the angled notch (which should be 8").
I hope this wasn't too confusing. But it's necessary to cut the pieces like this so you can get both sides out of one 3/4" piece of ply. That and because the ramp is taller than 4'-0.
Carefully cut the transitions you have laid out using the lines you just drew. Once cut, you can use these transition as your template to trace onto the plywood and cut out the other sides.
Frame the bottom using three of the 7'-10 1/2 long 2×4's for the front, back and top as shown above.
Frame the top using four of the 7'-10 1/2 long 2×4's for the front, back and top as shown above.
Clamp the bottom section to the top section and screw them together using plenty of 2 1/2" screws.
Any clamps will do, I just like to use Quick Clamps.
Attach the remaining eleven 2×4's spacing them 8" apart, on center except where noted above.
You will want to double up the 2×4's as shown. This is where the 3/8" plywood seam will meet and the double 2×4's allow a larger surface area for attaching the two sheets.
Starting where the first set of double 2×4's are, attach the 3/8" ply and work your way down the ramp. Then place another full sheet next to the first and finish off the first layer with a piece that's 1'-6 by 8'-0.
Attach a piece of 3/8" that is 2'-0 by 8'-0 and place it at the bottom of the ramp, overlapping the bottom layer by about 1 3/4". Then a full sheet and finally a piece that's 3'-9 1/4, it too should overlap the layer underneath it by 1 3/4".
It's best to cover this ramp with masonite and a steel threshold. Place a full sheet of masonite 1'-1 1/4 up from the start of the second layer then a sheet that's cut to 3'-5 3/4".
Now take two pieces of 1/8" steel at 8'-0 by 1'-3 and attach them to the ramp flush against the masonite.
Find a smooth wall behind an abandoned warehouse and see how high you can get. This wall ride isn't going to be the lightest ramp around, so you might want to scope out a good spot before you start.
