I love making rockets sending it far up in the sky and saying I done that with or without a header its still magic to me

My ballmill is made out of a toilet cistern float that screws on to an winscreen motor and runs from a 12volt power supply you only need about 6 or 8 balls in and it does the job well i put it on when i go to work when i came home job done it has a long lead so its out in the garden for safety i would put up a photo but cant work out how you do that its asking for a url?

I use plastic electrical conduit from B&Q. BUT the motors have been tested a LOT of times and never Catod. Even so they always have a VERY long fuse and are fired at a great distance.

One handy thing with this pipe is that the 35mm film cans with the edges that are flush with the edge, have a dimple in the middle of the lid. This almost clips into the end of the tube and a little glue holds it in place to contain the heading. A little match glued into a hole through the middle of the lid is all that is needed fuse wise.

If you do use this pipe I will say again. You need a LONG fuse and a large area to fire them just in case. I cut the tubes 50mm long to make endburners. You get a lot of cases for just over £2.00 cost.

I realise that this doesn't hold with everyones ideas but I do observe the precautions listed and I have never been able to get a static spark from it either no matter how I have tried.

Thanks for that i knew there must be a reason but i was pleased with the ones i done so when i use it i will go down the field and try paper in the garden thanks for not saying i am stupid

I also enjoy trying to fly a rc helicopter i have broken loads but getting better now nad have a blade 400 I am also a radio ham and work full time so its hard to fit it all in
