Exploding Targets

[MatCat]

Greetings all, I am really curious to understand what effect AL mesh size has on AN/AL mix? Generally most call for 300 to 600 mesh, but I have seen plenty of references to use of mesh up to 4000.

Man honestly just use tins of brake fluid and granular chlorine rigged up in a coffee tin and make it so the chems mix when the tin is shot

Don't use tin or any type of metal containers.

 

Chlorine may eat metal and could have early reaction.

 

You have a slow leak with container holding brake fluid or puncture loading.

 

Takes bit for the reaction to take place.

 

Produces a large cloud of caustic chlorine gas.

 

These are just some of the problems with using brake fluid and chlorine pellets.

 

You can make a hockey puck out of a 95/5 AN/AL target mix, unless someone is swinging a super sonic stick it's safe.

Do you make the puck using a binder, or by pressing it?

[dbooksta]

Doesn't have to be pressed or bound. (Remember AN is hygroscopic so presumably that would rule out water-based binder mixes.)

 

I put the mix in any disposable container that's handy, and I've even seen people just fold loose mix into a piece of paper and staple it to a target backer.

We talked about making pucks in another thread...Hmmm I proposed melting the AN and mixing in the AL. Was took ta school. Pressing..I know nothing.

If you put the mix in a Ziploc bag before putting it in the container, a bullet grazing and cracking the container will not spill the mix on the ground.

 

Cheap disposable containers that items from the deli come in work great.

[Seymour]

I am fully aware that there is no NEED to make it in to a puck, I was just interested in how it was done.

 

Now that I read it again I think that August was talking about Hockey pucks as a way of describing the insensitivity, rather than actually describing a method of doing it.
