I only own one machine personally, the one I purchased to make the cam. I prototyped this over many years out of pvc and other plastics until I was ready to go to metal. I've had to find people who had the machines to do this and learn how to program g-code in the process. As far as the contest goes...

pimpmann22: You can get a look at the machine I cut the cam with on the following site. http://www.maxnc.com I used the maxnc15 with the fourth axis. IT also was used to cut out the trigger assembly and grip. The grip accepts .45 style rubber grips, I just didn't have one handy when I took the photo...

In regards to an earlier version being shown, this is a different launcher and I have not until now released any of the above details of operation regarding the reloading system, indexing mechanism or bore sight. Here is a picture of an earlier model. http://i16.photobucket.com/albums/b12/solararis/...

The Eclipse is a pneumatically powered, semi automatic 40mm launching platform. This entry is my final pre-production prototype. The firing cylinder and drive cylinders are external in this variation. There is no spring in place or drive rod guard at the time these photos were taken. The trigger and...

Another safety device would be muzzle break style holes to allow dirt that has been rammed into the barrel to be banged out easily.


Oh, and Chaos: Is PINTball an Aussie drinking game?

Here is my patented MAKROLON bore sight that I hope will eliminate the problem on the Eclipse launcher.

I think I would be foolish not to offer the parts separately to allow others to make use of the safety that my metal launchers offer. Most likely barrel and ballast chamber parts. Perhaps drive indexer and valve assemblies too.

New videos soon and an actual unveiling in two days.

check this out. VERY useful link. If anyone figures out Maxwells demon in practice, call me and I will make you very wealthy.

I will be working on an engine design soon that uses air, magnetism, and thermocouples to generate forward motion. Amazingly enough, you should do a search on lego engines. Seems like a lot of lego fanatics have made piston and turbine engines using the air pistons from some of the kits.

Always make sure your gun is empty before you charge it. Even if you haven't loaded anything into it. I had something fall into an exposed barrel end while the gun was in my car trunk without being in it's case. I pressurized it in my friends garage thinking it was empty, but there was some unknown ...

I will be posting details in just a couple days. The cam has ramps for the spring loaded pin to act as a clutch unlike your pattern that is based on the same principles, but for the logic of my system wouldn't work sine it would rotate the shell 30 degrees off during firing. Mine stays put until aft...

No worries as you mates say down under. I won't do anything that could be construed as illegal. I don't think it will be as much of a problem as you might think since it has other uses that are considered useful as a lifesaving device. I'll be able to tackle these issues as soon as we get into produ...

Then we get to the parts issue again. IF someone buys an entire airplane worth of certified spare parts of name brand and assembles them, is it really a certified plane? Can you even call it a Cessna or Piper at that point? Really, all I have built is a air powered engine that spits paintballs out o...

Congratulations. You are the only other person that I've seen in the last six years to use a cam for their drive mechanism. The Eclipse Semi-auto uses a modified ramping cam that is designed to reduce friction and is machined from 7075 tubing on a four axis CNC. It is the most precise way to achieve...

Hahaha, that was a darn good example of how not to spell, even for online.
