Hey Peret, nice sized back yard you got there

Yes, but the lawn is in a terrible state.

That's very interesting - a 17 page thread! Too bad most of the early links have expired.

What's more interesting is how you located it, since it doesn't appear in the severely truncated list of topics I can see, which only goes back to February 2011. Is there some setting I need to adjust to see the older topics?

Another quick question being new to this and all........

What is the best way to fix a visco fuse into a core/end burner rocket? So far i tend to fold over the last 20mm of the fuse and try to wedge it in around 20mm past the clay nozzle and then selotape it to the rocket on the exterior. Obviously as the fuse burns down it destroys the selotape and a few times has fallen out of the rocket (dangerous to then go and retrieve the rocket). Is there any easy/preffered way to correctly fuse a rocket to avoid this problem?

Traditionally a 'nosing' is used:



With core burners you can fold the fuse over near the end and it should hold itself in, if this isn't enough to hold it a ball of tissue paper should do the job. Another commercially used method would be to to 'glue' the fuse in place with a NC-bound prime.

Fantastic.

Thanks!

I just wedge abit of tissue paper up in the nozzle holding the fuse firmly in place

[jermain]

Looks like tissue is the way forward!

On another note is there anywhere were i could get hold of decent ramming/coring equipment? Atm I am simply using a sawn of top of a broom handle and a drill bit (drilling by hand into BP) which is just about the quickest and most brutal way of getting blisters i have ever come across.

This bothered me for a while too. If you go into the desired subforum, UK Pyrotechnics (this section) for instance, and scroll to the bottom of the page you can change the settings. There should be a line just below the last topic on the page that says "click here to show filter options". Click on that, change the time frame to All, you may want to hit remember, and away you go. I think you have to do this for each sub forum. I haven't found a way to universally do it yet unfortunately.

most places are in the usa ,surprise surprise!, wolter pyro tools , firesmithtools
a useful tooling size guide is this if your making you own rocket tool sketcher

I know your pain! There are many sacrifices in this hobby, blisters included

Ah, thanks for that tip. It was set to 90 days. I thought the forum may have had an automatic purge that deleted old threads.

Blisters are part of the game, whether it be friction of a willow star u tested and wonderd why it was looking like a ball of ash and decided ( stupidly) to flick it to see if it would fragment, low and behold willow star stuck all over my fingertip OUCH !!!!!!

Hi jermain, all I use is a pinch of polystyrene from some waste packaging that is a little larger than the nozzle, When its pushed in it traps the fuse, and when the fuse reachers it it burns up. I've never had one fail yet. I first saw this in a commercial whistle rocket.
