Center Goal Hardware

An alternate technique:

- Get 10 metal (not HDPE) tetra "clovers" used to make the tetras.

- Take six of the clovers and bend one lobe of the clover to approximately 110 degrees. Let's call these the "bent over clovers." With three of these, attach PVC end caps to each lobe, and set them aside.

- For the remaining three bent-over clovers, attach a PVC end cap to the bent lobe. Leave the other two lobes open on each clover. Call these the "left-over bent over clovers."

- Bend the remaining four of the clovers into the standard apex shapes.

- Take three regular clovers and the three left over bent over clovers and pair them up. Put a bolt through the lobe of one bent-over clover, then through the lobe of a regular clover, then into a PVC end cap. Repeat for a second lobe of each. Add PVC end caps to the two open lobes. When you are done, you should have a clover assembly that has four lobes, one of which is bent at a 110 degree angle, with an end cap on each.

- Make a "standard" tetra from 48" lengths of PVC, using the standard metal clover with PVC end caps at the top apex, and the modified 4-lobe clovers at each apex along the base. When you are done, the tetra will stand on the three end caps at the corners, each of which will face down.

- Make another tetra, with 48" lengths of PVC for the three base edges, and 40" lengths of PVC for the rising edges. Do not connect the three rising edges into an apex. Bend the clovers on the base corners of the tetra so the rising edges stick straight up (i.e. do not angle toward each other).

- Lift up the first tetra and plug each of the rising edges of the second tetra into the open end caps on the bottom of the first tetra.

You might have to fiddle with the exact angles of the modified clovers a little to make everything fit, but it is possible to make a center goal out of PVC this way.
