The reason for wanting the unions is the ability of making the firing mechanism square and straight. I was having so much fun glueing everything together, that I ended up glueing the 2&quot;x1&quot; couplers into the 2&quot; T's before I realized what I had done. Looking at this picture you will notice what I had to do to fix it. It was not pretty and took some muscle, while at the same time hoping the pipe wouldn't snap.

Total Cost For Cannon: $82.12

That is the complete cost for the base unit of the IOD M01 air cannon. Pricing for the electrical battery box won't be posted until I find the majority of the receipts. The sad part, is that I know the battery box w/switches cost almost half of what the base unit cost is!

The schematic's for the electrical system will be posted as soon as I figure out what I did with them. Its not too complicated though. The relay could be omitted if you get a hold of a DPDT monetary switch, but I find the relay kind of cool! I originally wanted a DPDT switch but I couldn't find one when I needed the switches right away.

But that's just the beginning of it. The bottom switch (harder to press) triggers a 24v DPDT relay that not only activates the second switch, but also activates the 3v laser pointer attached to the cannon. When the laser dot is where you want it, you just press the second switch and KA-BLAM-O! &quot;What there's more?&quot; Yup, I also threw in a 25ft wired remote switch that can activate the laser and fire the cannon. Talk about the best of both worlds!

Now I do regret on skipping one of the items Andy includes on his PAC4. The item is the 1&quot; union. In fact, before I was going to build my new IOD M02, I was going to add two unions to the IOD M01. Except I ended up blowing all the money for the IOD M01 on the new IOD M02. Oh well, I will probably fix it later ($8.00 fix).

I went a little whacked out on the electrical firing system for the IOD M01. I have three rechargeable 9volt batteries which fire the solenoids when two monetary switches are pressed and the key lock switch is in the ON position.

I also added a ball valve and air compressor hookup right above the second solenoid valve.

My IOD M01 design which is similar to Andy Gustafson's PAC4 but has a few modifications. My first modification was to reduce the amount of stress points the high air pressure had to flow through after being fired. At the 2&quot; T, I turned it at a 45 degree angle and added a 45 degree elbow to put the firing chamber parallel with the air chamber.

I would take that blue jean off there because i saw a test the other day that said when they put more stuff around the chamber the explosion was increased. They put them in a steal box and with the jeans on it the box was shreaded. The one without the jean was just badly dented.

It doesn't really matter, but it doesn't do a thing, and maybe does more :?: but pretty cool, You should give it a paint job, and mod the sprinkler valves so they open faster, :D

its Glue.

/em rant and rave
Dude, this cannon was posted over a year ago...maybe you should check it out the dates on the last post before you reply with nothing more than "nice cannon" constructive comments are always ok to kick up a dead topic with but not just "nice cannon"

As for the PVC glew, are you using PVC primer? thats the purple stuff and should be right next to the PVC glue in Ace...

do you have any idea what you are doing PVC. you should check Here for how to glue PVC. Also learn to spell. it is almost imposible to read your posts.

Ler me translate for you:
Nice cannon. I buy the Ace Hardwere PVC glue, and sometimes it doesen't work. Have any ideas on were and what kind of PVC glue?

Thats 12 errors out of 25 words.
you would have failed your spelling test.

Also do you even think he will respond?

Yes the laser sight, although cool-looking, is almost pointless.
