The pics that have been posted are of some really pretty pads. What I'm going to post are of our club pads, not so pretty.
These where at least 7 years old when the pics were taken and they are not so pretty. They are put out into the field in October and sit out there until April. Then they are pulled apart and leaned up against the side of a sea container over the summer. They are now over 8 years old and have been out in the weather every day for 8 years. They still work great.
Just note, these are not easily transportable pads. We haul them a 1/4 mile from storage to the field and back just twice a year.
This is a 1010 pad. We have similar 1515 pads. The base is a 1030 bar with the 1010 pieces attached to it. The blast deflectors are part of the structural part of the pad. Those are steel and have rusted some, but surprisingly little considering the amount of time they have spent out in the weather and the amount of corrosive exhaust they have deflected over the years.
Here you can see how the deflection plates are attached to the 1010 rails. The deflection plates are what connect the 1030 base piece to the 1010 bar used as a T on the end to stabilize the pad .
Here is how the rail is attached to the pad. If you pull the upper and lower 1/4" pins, the central 1010 launch rail can be removed from the pad. In normal operation, only the top pin is pulled and the rod is tilted down to load the rocket. It is then tilted back up, the pin installed and the rocket launched. Of course we used stainless steel pins so they don't rust while sitting out in the field. BTW, there is a notch in the steel deflection plate assembly so the 1010 launch rail bottom can kick forward when it is tilted back for rocket loading.
This is the bottom of the T. When the launch rail is tilted back, it rests on this vertical piece.
These are not pretty pads or easily portable pads, but they have been great as club pads and have held up to 8+ years of sitting in the Virginia weather. I'm sure we will have to replace the deflector plate before too long, but the aluminum parts have held up great. If you are looking for durable pads that can take a lot of abuse, these might be what you are looking for!
