DIY Mid-power launch equipment- i.e. Help a noob for Karma points

Howdy,

        The day has come for me to move on up to mid-power rockets.
Custruction has begun on my first mid-power rocket and while I work on
that I plan to start assembling my lauch equipment. Some folks had
suggested that Do-it-yourself (DIY) equipment was the way to go.
Specifically, the 1/4" launch pad. Does anyone here have any suggestions
for building a launch pad out of parts?

Also, I open for recommendations for ignition systems. I understand my
old estes launch controller just won't hack it. I'm fairly skilled with
electronics and I'm not afraid to build, but I'm also open to purchasing
this as well... All comments are welcome.

Thanks a million!

Jonathan

I built a pretty good launch pad out of PVC, some s***wood, and some U-bolts.
 The basic plan is either on ROL's Info-Central or on EMMR; I can't quite
remember.  I got a 4' 1/4 rod at Home Depot; a bit short but it seems to work
fine.  

As for the controller, I bought Estes Pro Series controller (it takes 2 7.2
volt RC car NiCd batteries)  The batteries are a bit pricey, but I don't have
any problem lighting AT Copperheads with just one battery.  I haven't purchased
a second yet.

This setup works fine for midpower.  I've flown a bunch of LOC kits: Graduator,
Onyx, Aura, and Lil Nuke with it.

Good luck and have fun.  There's nothing like lighting off your first composite
motor after burning only Estes motors.

Go to ROL and go to info central then ground support, you'll find launch pad
ideas, firing consoles etc. A lot of great info for you. Good luck and
welcome aboard.

First, use the launch pad that is on EMRR that is for the rail, but use a
rod!

Make a simple 12v controller. Use a type 53 bulb for cont. check

Jonathan,
We built a great mid power pad out of 1" PVC fitting from Menards/Home
Despot/Lowes etc.  1 cross, 4 45 degree elbows and 1 length of pipe.

1.  Drill a 1/2" hole through the cross.
2.  Glue in 4 - 8" lengths of pipe into the cross.
3.  Glue on the 45 degree elbows all pointing down.
4.  Cut the remaining pipe into 4 equal pieces for the legs.  Don't glue
these in. They are removable so the pad takes up less room.
5.  For a Blast deflector we went to the bargain tile bin and found some
large hexagonal ceramic floor tiles.  We attached the tile to a 3/8"
piece of plywood for support.  Then, this is the hard part, we drilled a
1/2" hole in the tile/plywood using a masonry bit.
6.  Get a 1/2" bolt long enough to go through the cross, plywood, and
tile with about 1/2" to spare.
7.  Purchase a 1/2" coupling nut.  They are approximately 2" long.
Drill out about 1/2 of the threads this allows you to use larger rods if
you need to.  Drill and tap a 10-32***hole in the side of the nut
and purchase a Thumb***from the hardware area. this is the clamp for
the rod.
8.  Assemble the cross, blast deflector, and coupling nut and you are
ready to go.
I will try to post picture of the finished product on a.b.m.r.

Jonanthan,
I used the plans i directed you to before with  a slight modification, from
Harbor Freight Tools I obtained a 1/2" Jacobs replacement chuck for a power
drill.  This allows you to use any size rod to 1/2" or a rail with up to a
1/2"
stud.  I have stuck to rods for this as is only for mid and smaller power.
I also used schedule 40 1 1/4" PVC as was a little beefier and didn't cast
much more at Menards.
Through the cross center piece drill (use a new or very sharp bit) a 1/2"
hole run a bolt with washers on both sides through this into the back of the
chuck.  The ceramic tile idea for a blast deflector sounds great!  I just
used a piece of 2' X 2' sheet metal I had laying around supported off each
leg by a 2X4 block spacer to bring it to the height of the chuck.

Steel, boy!  Ah say Steel!   Iron, metal ya know?
This one won't fall over in a breeze and won't launch itself if you're
rocket gets stuck on the rod.

Here's a great launch pad that will work for rockets up to J power, using rails
or rods up to 1/2". It's super cheap, super easy, small, light weight, fast to
set up, and doesn't require any special tools to make:

I have a real simple launch controller detailed on my site.. Made mine ages
ago, and it is still going strong. Lights clusters with ease.

Hi Jonathan,

   Here's a link to my homemade launch control.  Hope it helps you.  Good
Luck.
