The jumps standards you will be building allow for jumps of approximately 4" to 18". The bars fall off easily enough to prevent injury to the rabbit that does not make the jump. The instructions are for making a pair of uprights that constitute a single jump.
Step 1: Cut the 10' PVC pipes into the required lengths (Note: Easiest to do with a ratcheting pvc pipe cutter < $10 for a cheap one):
2 x 17.5" pieces for the uprights.
4 x 3.125" pieces for the legs
4 x 1.25" pieces for connectors.
Step 2: Using the exploded view assemble three tees together as shown to create the base for one foot. The connector pieces that connect the 3 tees together need to be cemented (with PVC cement for plumbing). Make sure they are aligned with two of the tees on the ground and the middle tee pointing straight up. Now make a second foot base the same way.
Step 3: Attach a cap to each of four leg pieces. Insert the leg pieces into the foot bases as shown in the exploded view picture.
Step 4: You need to find something similar to the old kitchen cabinet drawer I used here to hold an upright so you can draw a straight line on the upright.
Step 5: I used a piece of masking tape over the drawer to protect it and also placed marks at 1.5" from the bottom end and then every 2", mark these points on the upright for drilling.
Step 6: Using a hammer and a nail with the upright still in the drawer make an indentation at the drill points. Without these it is extremely hard to start drilling on a round pipe. Repeat steps 4 thru 7 for the other upright.
Step 7: Now drill eight 1/4" holes at the marked points completely through both of the uprights at a 10º angle. Note the point you marked should be lower on the upright than the drilled exit hole. This probably needs a setup like the one shown here or be done on a drill press (2nd image). I originally tried a 15º angle but found small rabbits did not dislodge the bars on failed jumps winding up bouncing off and on their backs.
Step 8: Put bolts throught the holes you just drilled in the uprights.
Step 9: Slide the plastic tube over a bolt then cut off the tube near the end of the bolt. I found using a pair of tin snips was the easiest way to cut the plastic tube. The plastic tube you use should fit snuggly over the bolts to hold them in place.
Step 10: Push the uprights into the feet. You now have a completed jump standard.
Step 11: We now turn our attention to making the jump cross bars. Bars can be anywhere between 16" and 24". I find 16" is a little too narrow. 18" is good but using 20" allows you to use an entire 10' pipe to make 6 bars without any waste. Cut the 10' PVC pipe into pieces of your desired length.
Step 12: Wrap the electrical tape around your cross bars at an angle to make stripes. Suggested tape colors are blue or purple since a rabbits vision I believe will be able to see these colors.
