Like the name?

This is my first hybrid launcher, thanks to this site. It's nothing fancy, but it is my first and I am proud of it.

I've not taken past 6x, due mainly because I only have a bike pump. I just got an air compressor, so we'll see where that leads.

It is made of 2" Sch40 galvanized pipe. The meter is comprised of 1/4" nipples and 1/4" ball valves. The frame is made of two 2x4s nailed together. This keeps it off the ground. I plan on building a tripod for it one day.

Here is a link to the spark system: Hubbrid Spark Plug

Here are the pics:

This is the meter.  Note the pop-off.  It is there to regulate the propane, in case I add too much.  It is there, also, in case the burst disk does not rupture so I can release the buildup without taking the union apart.

Nothing fancy.  I JB Welded the wires to the electrodes and super glued a piece of pipe over them.

Very nice job
there have been a lot of hybrids lately

and is that a 1in or 3/4in union?
eighther way I reccommend you switch it out with a 1.5in union to exploit the power potential of a larger bore barrel.

Very noice! (At the risk of sounding like pimpmann22)

Do you use the fill-from-meter method of air injection?

bigbob: I don't really have a desire to increase the union size (I just wanted my feet wet with a hybrid, plus, it ain't coming off anyway).

Maniac: I don't know about a video. Maybe.

Mark: In the meter pic, the schrader is on the left side, although it may be difficult to see. The schrader has seen better days.

The union is a 1". I already had a 1" x 30" barrel and I built the launcher around it (although some would argue with that). It has a ratio of about .8 to 1.

I like the spark plug and i think its what im going to use on my hybrid (eventually :roll: ) but also what is the insulation on the wires? Is that electrical tape? And if not, then would electrical tape be a good insulator?

But overall, its nice and i like it. How about ammo?

The insulation is heat shrink tubing. I drilled two holes in the cap just slightly bigger than the coat hangers. I measured them, sharpened on end and looped the other, then put the tubing over the hangers and shrank it. I double layered it to make sure it would not ground out against the chamber. To secure them, I filled the pipe cap with JB Weld, then tightened down the nipple.

I guess electrical tape could work.

Ammo? Whatever fits in the barrel. It's a 1" barrel, and it holds dirt, pecans, rocks, and whatever else. Nothing permanent yet. I haven't shot a potato out of the hybrid yet, but this barrel has seen some starch movement.

A marble barrel sounds like a good idea. I like to break $#!+.

As far as EVBEC, I've never taken the time to learn the program so I wouldn't know. I get familiar with it and see what it says.

The biggest reason I put the pop off on the meter was because it was the only "plug" I had to put in the tee, which I already had. Make sense?

In other words, this is basically a spare parts gun and it costs me about $10 to build and get working. Almost every piece on here was used on another launcher.

And, Spudblaster, I told you it looked like yours.

As far as the name, it's original. I can't remember how I came up with it...
