The spectators that have been exposed to my butt crack will thank you

Here's some pics of the launch pad I built from an old office chair base, steel plate and steel angles. Works for me!

Because this design will sweep 360 degrees in azimuth and 90 degrees in zenith, it can cover virtually any point in the sky. It tilts to horizontal for easy loading and is quite stable when pushed firmly into Texas clay soil.

If I could produce this item for a fair price, would people buy it?

Looks pretty good. If the price is right, I'd buy one.

This is from a design on TRF that I modded for our use.
This pad will handle H-J if you stake it down.
I can break it down to three pcs.
0-90 degrees to load rockets
360 degrees for wind adjustments

Tripod Rockwell Jawstand
1010 Rail
Blast Deflector (has rail buttons two ea. to mount to 1010 rail with stop)

Depends on how large of motors you want to use.
I have launched an H128 off of the Estes Porta-Pad "E" with a stiff 1/4" diameter 5' stainless rod and anchors holding the legs to the ground, but don't reccomend it.
The original Estes Pro Series pad and Pro Series II pads are both better than the Mantis.
The Mantis is actually rather fragile.

I like tmacklin's chair-pad! I assume it has anchor spikes instead of casters.

Thanks, I like it too! And yes, I pulled the casters and welded steel rod spikes into the holes. Works great on the clayey soils around most of north Texas but might need something else on hard pan out in the desert southwest. It will also accept rods from 1/8" to 7/16" in diameter and I suppose it could be modified to accept 1010 rail.
