ok so i wanted to build a rail launch pad becuase i dont really like lugs. I have no idea wear to start and does it have to be made out of metal or can it be pvc. Any help and estimated costs would be great. thanks.
 
If you want an awesome launch pad for a low price, check out Ron's Pads at www.ronspads.com

You ain't going to find anything better cheaper than those!
 
hey johnnie just wondering were you got the rail and how much did it cost for the whole pad.

BTW great pad. looks amazing.

The rail was the largest expense. There are a number of places to purchase, like ebay: https://search.ebay.com/8020-extrusion_W0QQfnuZ1QQfsooZ1QQfsopZ3

McMaster-carr: https://www.mcmaster.com/ ( type in: "Aluminum Fractional T-Slotted Framing System" in the search window)

be warned, it is not the price of the rail, it is the shipping that gets you. For ebay was cheapest. Try to find local resellers for best pricing.

Here is a list of some home-brew launch items (including pads with rails):

Here is the design my father and i mimicked:

Here is our finished product:

If you construct a PVC launch pad, i'd suggest adding a floor flange for added support. If you don't glue the floor flange, the floor flange will adjust to differences in ground level. In our case we really need the floor flange as our pad legs were too parallel with the ground...

It works:

An 8 Foot Section of 8020 rail from McMaster-Carr cost me $30 plus an additional 15 for shipping = $45.
The total cost for the pad was about $80.

Hope that helps,

$325!!!!!!!!!!!!!!!!

...and this one is awesome too: https://www.jcrocket.com/prorailbase.shtml

I designed the HPR PVC Pad first, and built the second one from John C's plans here: https://www.rocketryforum.com/showthread.php?t=10898&highlight=high+power+pad

Well, firstly, you can't compare dollars vs. dollars for something complete with something you build yourself.

You need to include cost and labor when making the comparison. Where a rough estimate of labor would be the hourly rate of what your regular job is now.

So if the materials for your pad cost $100.00, and it took 10 hours to design and build, and you make $50.00 per hour, than the true cost of your homebuilt pad would be $600.00!!!!

In otherwords, you can pocket that $100.00, work 6 hours overtime, and buy that $325.00 mount for much less than your homebuilt mount.

But building and learning is the secondary benefit...that PVC pad design came from the 16-pound melon sitting on top of my shoulders.

Now then, the materials (indcluding rail) cost me $75, the design cost me a an hours worth of sleep whilest I jotted it down on paper before it left my head. From start to finish, it took four hours (I took my time)

So lets plug your numbers in...since we are not including a labor of love here, we will use the time we value as precious...although I do not value my labor at $50 an hour, I will be as realistic as I can: 1(hour of sleep) + 4(hours of labor) + 1(hour to shop for materials) = 6-hours. X(times) my actual work labor rate of a whopping $16.10 an hour = $96.60

Still plugging here: $75(in materials) + $96.60(in labor) = $171.60

...for a grand savings of: $325 - $171.60 = $153.40

I am not saying that Ronspads.com are not worth the price, what I am saying is I can build mine cheaper. The above numbers mean squat (yours and mine). I designed and built one of the best pads I will ever own. You can't put a price on that. I know of at least two confirmed fliers who have built and flown from this design. At least one of these fliers has since burnt his to the ground...litterally!! Regardless, I have done all of the hard work, so strike a hours labor off of this design (no sense re-inventing the wheel) and you have yourself one kick-fanny pad, for less than a bill ($100) in parts (price your labor however you see fit).

OT here: my pad has also been submitted to: https://www.pvcplans.com/pvc-pipe.htm

Lots of cool stuff at that website.

Final note: I will never let my ingenuity get in my way because someone else has done something similar or maybe even cheaper...thats why I scratch build everything now...it so much more rewarding.

Which is exactly my point!

So you cannot say Rons Pads are expensive by just looking at the price. Some people may really value their time (maybe they have a family and lots of other responsibilities) and don't have time to build a custom pad. In that case, a commercial built pad has much "less cost" than spending lots of time building your own.

Cool pads, and probably well built, but that is more then I would pay. Anyways, if you read “eaglefn68’s original post he states that he wants to build, not buy, a rail launch pad.

Like "Randy K" said, "eaglesfn68" wanted to build...besides the learning to construct here is the point, anyone can buy...it's easy. ;)

Building a launch pad certaintly isn't rocket science either. Four legs and a rod. Not sure whats to learn about doing this. I think most people learns the necessary skills to build something like this when then were about two years old. ;)

In fact, i believe my two year old son has a construction set which is very similar to putting those PVC pieces together. ;)

I would not have expected such statements from someone such as yourself...to bad.

One variation on the pvc rail is I used the 2" pvc and an 8ft 1.5 rail.
It has had no problems handling J flights and 12pound rockets and can be done for 100.00 not including tinker time. Plus the bonus is you always have it for when u want to fly and do not have to rely on the club.

Good job Brian, nice looking Amraam too.

Hey EAgle did you ever do a pvc pad ?
I just want to share a blast deflector idea...
Pic of mine, I dont mind saying I really like it, especially after I tried a 45deg cookie sheet pan which worked up to H's. As soon as I went to J's it folded it everytime, then I tried 2 together and same results. This huge pvc elbow is cheap and has worked very well and I like the dramatics also.
