    Any Plans Available For LPR Tower?

    I'd like to add an adjustable Tower launcher to my gear, but the one Apogee sells seems a little steep. Does anybody have plans for a DIY on the cheap?

    There really aren't any Dirt Cheap ways to create an adjustable, Accurate and Stable Competition Tower.
    There are several ONE Size only towers that aren't all that expensive but you need one for each body diameter your flying. I built mine from scratch using 10" diamter PVC Pipe rings with 1/4" Aluminuim stiffener rods and 1/2" x 3/8" x 1/16" 36" Aluminum Channels for the 5 adjustable internal rails. The thing ended up costing about 200.oo by the time I added a drop-down Piston base and 48" folding legs.
    There are lots of other style tower out there, One just needs to do some research and decide on What You want to do with your tower.

    Below are a few pics of a few different style towers you might get some ideas from:

    Thanks John. I really like the one you show in photos 5 & 6. I did find the R&D papers on NAR that describe the tower that Apogee's is based on, but it's difficult to understand it's construction by the way it's written.

    Not being able to see what the plan is prior to spending money is a little weird, I think. I could assume that it is the same as tower in the R&D report, but we all know what can happen when you assume.

    Being a cheap S.O. ... I mean frugal gentleman myself I would agree. But consider that you're looking for a specialized, limited use bit of kit in a niche hobby. Other than Apogee I think Giant Leap makes the only other commercially available tower: https://giantleaprocketry.com/produc..._Launch_Towers

    I would also guess that the craftsmen on here; the ones who go to the garage and throw nuts, bolts, aluminum and wood up in the air with a "Valar Morghulis" probably don't work from plans. The NARTS could be the only game in town. Might be worth pinging this guy to ask for a peek:

    Well, there's another supplier I hadn't heard of before. Thanks.

    From what I've been seeing of the different designs I've been able to locate, I think I may just try to cobble together something on my own. I'm pretty sure I can come up with something for less than what they're being sold for commercially... Perhaps not, it's just something I kind of wanted to play with. I don't see me competing anytime soon, or at all more than likely (I haven't competed since the mid/late 80's when I was a teen), so it's not a big priority item to have. Then again, I recently took my girlfriends 5 year-old grandson with us to launch rockets and he's already asking when we're going again. It might be time to help him build a rocket of his own .
