There's a distributer in Toronto, which is where I get all my rail & hardware from: CPI Automation Ltd. 5155 Timberlea Blvd Mississauga, ON L4W 2S3 Canada Phone: 905-625-4805 Fax: 905-629-8409 E-Mail: [email protected] URL: https://www.cpiautomation.com

Great project, your work is excellent; using the 6DoF sensor was a brilliant move. Welcome to the roll stabilization club!

For round cordage, a Figure 8 or Figure 9 if the knot is on the end of a rope, or Alpine(butterfly), if it's mid line. If you're joining two ropes together, use a barrel knot on each end. For webbing, a water knot is your best bet,; essentially its just an overhand knot in the webbing, with...

Good guess! But unfortunately its for our club's(NAPAS-TRA) big upscale "Freaky Flyer". It's a monster, Flying on a complex O at LDRS this year. I won't be attending due to work schedules; I'm bummed. Though I'd love to build another, I just don't have the time with all the projects on the...

Thanks Grouch! The 80/20 rail lathe set-up is by far my favourite shop tool. And it packs away into a corner. Lathe: 1- 72" X 1" 80/20 double rail(1"X2") main chassis 4- 16" X 1" 80/20 double rail(1"X2") upright bearing supports, back supports. 4- 12" X 1" single rail (1"X2") for...

Please go visit this for construction techniques; you can spend days looking at the information: Vern Knowles Rocketry Website Vern has done it all, and his project documentation is exceptional. Don't forget to write him and thank him for his work. Happy Flying!

Great system, Mike. Well done.

I'm going to recommend the Entacore Aim USB. Or perhaps their new GPS, if you've got a flexible budget. For me, its everything I needed to successfully perform dual deployments, even under some crazy situations: https://rocketryforum.com/showthread.php?t=34230 I use them exclusively in all...

Thats a great set up; is that bolted up for each shot? Or is there some kind of ram/jack to secure the breech? PT

Yes, the chunkers are a quiet bunch; even more so than rocketeers. I think the question everyone wants to ask is.... Can we build an air start rocket, and tube launch it with the VERA??? What a spectacle for one of the big Rocketry events. If anything, it makes for some good "techie"...

That's awesome! I was hoping to learn about your valve & air supply system, to pass on to the "Chunkers" I met in Delaware. You should definitely attend a Chunk event, or at least say hello on one of the Chunkin' social network pages. You're like a GOD to these guys. I'll make sure to say...

Yeah, do you have any contact info for him?? PT

A fun project for Discovery Channel, putting a camera projectile into the worlds biggest pumpkin cannon.

Replied, payment sent.. Thanks!

For this application, I use Firgelli 12 V mini linear actuators(2), hooked to a mosfet relay circuit, triggered by an event channel(apogee) on the Entacore Altimeters. The brakes are then retracted using a limit switch that reverses polarity upon main separation & deployment, ensuring they are...

One screw on a key chain camera will work great; just make sure it goes into a bulkhead, then use some tape to align it. Great job.

Hi, Will that cost cover shipping to Toronto, Ontario, Canada(M6R2V5)? If so, I'm like to buy eight of your switches, please. Let me know at your convenience. Patrick

Thanks. The next one is in the works; I'm going for an upscaled "Javelin" style projectile: -8.5" X 60" Carbon Airframe -Active roll stability, taken from my EVA 2 airframe -folding fins, to eliminate the Sabot -3D camera set up -Active air brakes, deployed at apogee by the AIM USB 2...

Jim, thanks for the kind words; your immaculate CF airframes were a huge inspiration for the Sabot project, thank you. As for "VERA", well that's just plain cool. I'd love to know what he's using for a release valve. Some guys have been seriously talking about air starts from cannons, much...
