Piston on mines

[erid]

How would I make a piston for a mine? I've seen them but can't find instructions anywhere.

aren't they just a disc with holes punched through it.

For smaller mines, I just use a thick paper disk with holes in it to allow the stars to ignite. Never had a misfire, but for big mines spending the time making a nice piston is probably worthwhile.

The piston I use for my mines has a pulley shape:

Two discs and a small tube, glue them together, and drill some holes through.

thank you, this was very helpful.

With fragile stars or comets that are made from soft compounds, use several layers of regular corrugated cardboard glued together with a few holes drilled through the stack. It cushions the load very well.

I have used this method for a very long time with many starmines, it is cheap, easy and works very, very well.

If you choose to use Nighthawk's method you may want to consider taping a piece of tissue paper over the disk in order to prevent the lift from migrating into the stars.

 

I personally use a 2 disk method with a wad of newspaper in between.

I always contain my lift inside a smll nylon baggie. I find it works better.
