Very nice propane spud gun with range of 150-200 yards for under 100$ should i post?

So i spent the last few weeks designing and building a very nice powerful and yet simple propane spud gun. When i first realized i was going the cleaner burning more powerful propane way, i came to Instructables first. but after some hard looking i found nothing on these cannons, so i made my own plans fros online sights with chamber calculations and what not. Based on my results i felt it neccesary to post my results and what ive discovered about this cannon, however i am always busy and im just wondering if it is worth the time, if there is anyone else out there looking for plans for a successful cannon like i was.
