How to Build a Halfpipe Step 2 TRANSITIONS

Before you start construction be sure to read understand and follow all the safety instructions that come with your power tools.

First read and follow the ground preparation section of your plans. Then you can begin your transitions.

Two transitions are cut from one sheet of plywood and it should look like this. Scribe twenty inch line on a sheet of half-inch plywood using a two-by-four as a guide on this line measure sixteen inches from the edge of the plywood and place a mark there.

Next measure six feet up from the line and mark the axis point with the spike or a screwdriver if you're doing this on soil.

Tie one end of the string to a spike and the other end of the string to a pencil or marker the pencil should touch the twenty inch baseline when pulled tight.

Scribe the transition line by holding the pencil vertical and the string tight. This is one of the most important steps of building your ramp, be sure that the curve you draw is smooth scribe another line in the opposite corner from the first just as you did in step one.

With the plywood raised from the ground, cut out the transition. Be careful not to cut over the curved line.

Flip the newly cut transition over diagonally and trace the curved line using the first transition as a template.

Cut out the second sheet of plywood and discard the surfboard section.

On the second sheet of half-inch plywood cut out two more transitions using the first transition as a guide using the first transition ensures a more accurate duplication line up the four transitions and drive in three screws to hold them together along the transition edge mark the positions of the two-by-fours be sure each transition is marked remove the screws and lay the transitions on the ground in two groups and eight feet apart from each other.

Have an assistant hold up the unattached and until screws can support it.

Attach the studs to the transition using three inch screws to screws at each end of the stud.
