My goal for this thread is for it to be a collection of finished launch pads, sort of like the galleries of finished rockets in a different section of TRF. Not as a replacement for "how to" build threads (please continue to do so, we love to see your progress), but to function as sort of an index of "what is possible" for people or clubs starting their own and looking for ideas. So, please post pictures of launch pads you have flown from or your own completed ones. If you choose to do a build thread (yes!), put a picture or two of the completed pad here, and maybe a link to the build thread for people to follow. You can also post a picture of your project in build, but please keep it updated by replacing old photos as you progress. I hope this will be a bit easier than doing a search for pads and then sorting through pages looking for the final product. Cheers.

So, I'll start off. 1st picture is my ubiquitous Rockwell JawStand pad, which I use for rockets up to about 20 pounds. Easy to build, setup, and use, though not study enough to carry much weight. 1010 rail.

Second photo is my trusted Quad-pod, good to about 40 pounds. I had a little trouble with it blowing over in light winds when new, so replaced the short stock tubular legs with longer 1" square stock, with longer over-center locks to widen its footprint and lower the center of gravity. 1010 or 1515 rails. Also replaced all the hardware with stainless.

The next two are works in progress. These pictures will be update (replaced) as work progresses.

First is my next generation Heavy Duty pad. It started life as a baseball swing-trainer, which I found at a garage sale. It has a very stable footprint yet easily folds for transport. Just have to attach a mechanism to hold-n-fold a 1515 rail.

This post is/will be for a small trailer pad, utilizing a 3.0 meter (9.84') section of F33 Global triangular truss and a 12' x 1515 rail. The base is made from 2" square steel and recycled skate board grind rails. Design spec added that it has to fold up and fit inside my existing rocket-dedicated trailer.

Nov 2020 progress update - about 95% complete. scale model built as parts buck, chassis of full-size mostly finished with minor details yet to complete. The truss is hinged at about the 3' level to reduce the dead weight needed to lift when a rocket is loaded. Build thread here

I flew off this pad quite a few years ago at an early MidWest Power (Oct 2008). I don't know who built or owns it, but I love this pad! Very stable footprint, legs fold for transport. Windage adjustable in elevation and azimuth.

I really like low pad designs. I just don't like climbing a ladder to arm a rocket.

My design that incorporated several ideas I seen on the forms. I had it welded up by a local fab shop and all aluminum with removable legs.

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.
IMG_1289.jpg

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 .
IMG_1290.jpg

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.
IMG_1292.jpg

This is the bottom of the T. When the launch rail is tilted back, it rests on this vertical piece.
IMG_1293.jpg

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!

I spent some time with the fab shop getting it right. They were fun toward with. It was 475 plus tax. They were hoping that I would 'get the word out' that they have built this prototype and have the jigs now done to build more so would be floored that others are interested. You can speak to Jason at 250-286-9992. You should know that they did not supply the rail or the angles that connect the rail to the pad. I did that but they would be able to copy mine and make it much better. Jason can call me if he wants mine as a template. Please let me know if you call him and I will help if I can. I'm in town.

Do you fly in Kelowna? Is there a local club? Msg me, I'm looking to build up my network in the province and do travel to fly!

Cheers

Hey thanks for the reply. 475 is not bad at all for that pad but I will have to wait as the wife says so :). when I am ready I will be calling them. I don't fly in Kelowna as there is no where to fly really or at least that I have found yet. I will be looking around in Kamloops as there is places there that I have flown before. Do you fly on the island much? Have you been to any big launches?

talk to you soon

I just finished a 2 1/2' tower for my small high speed launches. Tower has a removable base with integrated blast plate and ground spike. With the base removed it can drop into my universal launcher using a rail adapter.

Nice! I will throw up my Centuri launch pad clone as well. This one is made of oak and is almost double the size of my original LIA-100.

I made those for my club (3x);
Specifications asked: the height when loading, loading hinge and adjustment on 2 different levels, and a central foot to climb the pad. The legs are removable. Powder coat makes them easy to clean.

Another one, in stainless steel. Two spring pins gives 11.25° increment when turning the rail. Legs fold.

I may steal a couple ideas from Crumb fires stainless pad form my next project. Very cool! I will keep it rolling with a low to mid power pad. This one is PVC and has 6 C batteries with a 12v relay in one of the legs. Fuse protected and using a arm indicator with buzzer this is my 9 year olds favorite pad. Elevation adjustment pivots on nylon bushings captured under the washers. Topped with a Harbor Freight saw blade (teeth knocked off) and drill chuck on a hollow bolt. Legs are friction fit for easy transport.

I made just about everything on this one. With my 9 year old the turn buckle makes adjustment way easier. And the main pivot does not need massive tension to keep a larger rocket in place. The center post is a pice of 1" square aluminum mounted on a pice of 2" L. The blast plate is a pice of 14 gauge stainless with a 14 gauge galvanized support plate. The plates are held in place with a hollow 3/8" bolt. The rod drops through the bolt into a well in the center post. Two thumb screws hold the rod in it in place. The entire thing pivots on a hardened shoulder bolt that has been pressed into the base. The shoulder passes through the center post and L with the threading staring just shy of the adjusting nut in a compression washer. Adjustments are made with a 4" turnbuckle. The ends of the turn buckle have been resized for nylon bushings for pivots. All that is held in place on the base with another 3/8" bolt. The bolt ends in a 3/8" to 1/4" coupling nut with an eye bolt. The eye bolt is for a sand bag or stake to attach if needed. All the hardware I purchased at the local ace. This is my 4th or 5th build on the Centuri style pad. I just think it looks to cool not have one around. Here are some pictures I took before final assembly and finishing. The only thing I added in the end version was a 20 degree elevation stop and ignition wire clip.

You should fabricate your adjustable bracket assymble and sell them.. I'd buy one.. I tend too think the old style Centuri pads are awsome ( mine's not exactly a Centuri reproduction , more of a kit bash between the Estes legs and the LIA 100 top plate) but I intend to make a couple true reproduction pads for my self , son, and friends.. your adjustable top would make an excellent finish to them..
