thanks a lot. also i was thinking of buying a press for it.

do you think a 3 ton arbor press is enough?

or shall i buy a 20 ton hydraulic one?

thanks

to be honest, i dont think it does.

i was thinking more along the lines of a paper tube rocket.

also what types of pressure are sufficent and methods of pressing..

any experience out there on this?

those are two mighty thick hemis. should make a decent bang
should look really nice though, i love palm tree shells, especially with 8 comets... thats a lot!

both are core burning. the only difference is that one has a large diameter core and nozzle and the other one has a smaller nozzle size and smaller core. should i just go with the first type? the large core and large nozzle (burns v fast rises for a while after) as this should be able to lift more

I have tested the rocket and it wasnt bad. The rocket went up about 50 metres and then started curving. There was a nice smoke tail as would be expected of this type of propellant. The rocket burned very long so perhaps a shorter but faster burning propellant would be better.

Because of this i would say its better than dry mixed candy propellant, and with an addition of a few % of iron oxide this could be as good as molten candy propellant
