Re: Frisbee launcher
The clay pigeon setup usually imparts spin from the arm - As the arm rotates, the frisbee/pigeon will move outwards along it from the centrifugal force. The arms usually have a little rubber U-shaped channel that the outer edge of the disc can maintain contact with. This is how the disc starts spinn...

Re: Anybody else going to IREC next week?
Nice pictures! Any interesting CATO's or were they mostly all succseful launches? Looks like one in there possibly late stage.
Any interesting rocket chemistries? See some interesting colors in some of the pictures

Re: Frisbee launcher
This guy has made a pneumatic clay pigeon launcher - you can probably abstract an idea from his basic mechanism:

Re: Is spudding dead?
...You could make this site a whole lot more popular by having step by step tutorials on the front page with immediate results... I think there was one time in this site's history that they tried to promote posts from the build log - sort of make a different project a 'featured' one every week. Spu...

Re: "Offtopic-posts-topic" NSFW
Nice work!
Got a close up of that rear disc mount? And I'm guessing you had to get a disc compatible rear wheel (hub)?
I always wanted to build a cool steel framed city beater bike - they're pretty common now but weren't always haha.

Re: Noise cannon for RC planes
Just noticed this thread pop up to the main page again - all I can say is WOW! Great progress! Love seeing more work done in the field of detonations! :D :D Good luck in your future ventures - Do you have a picture of how the noise maker is installed in/on the RC plane? And what is your theory/hypot...

Re: Automatic Piston Hybrid Cannon Design
What you are describing is precisely the conclusion Utron came to - and if you view the Defense document below - you can see their solution!

Re: Modeling software for CNC (Mach3)
Mastercam, however you choose to obtain it, is very friendly with SolidWorks. I've used the two together for CNC Lathe, Mill and EDM (no... not the music lol). And I don't consider myself an expert by any means - it's just a reallllly good tool path program that ties into SolidWorks really well and ...

Shyasuna -
Toolie I believe is just the name of a person - as you may have found. Here on spudfiles, it is a small community, so new discoveries tend to be named after those that first introduced them to the spudfiles community.

Re: Japan Made Pneumatic Cannon "Exhaust Cannon"
Shyasuna - Thank you for joining! Your work is amazing, and the level of quality is as well. I love the quality of the drawing you posted above as well - looks like a very well designed and thought-out iteration of a Toolie valve - http://www.spudfiles.com/spud_wiki/index.php?title=Toolies_Piston_Va...

Re: "In the world of spuds today"
ITWOST,
I stumbled across this guy's YouTube Channel...
https://www.youtube.com/channel/UCZPyWR ... 4q6Ek3NrhQ
Anyone seen his work before or know who he is? Seems like some interesting creations and a good bit of professional level machining involved (at a university I'm assuming?)

Re: Noise cannon for RC planes
Another property of mixed gases you may want to explore is detonation - something that will surely make noise and not require a rupture disc to do so. Typically detonations are not something we spudders want - but it is a commonly used effect of rapid burning gasses that is employed everywhere from ...

Re: Noise cannon for RC planes
How many noise shots are you looking to produce per flying session? You may be over complicating it by trying to do a repeating design - which albeit cool - may be overkill. If you're trying to simulate high repetition main gun fire - I can understand the desire for repeatability though! I'm thinkin...
