The other day I used the lathe at work to make an end burner bottle rocket tool (6mm tube diameter).

Material is 6mm aluminium round bar, an M6x1 thread in the base and for the changeable spindles, the base is made of a large 3" scrap piece of aluminium they gave me in the tool room at work. The hole size formed by the spindle is 1.95mm, 11mm in length, and a 3+1/2" rammer with a 2mm hole drilled to a depth of 15mm, to give plenty of clearance for the 1.95mm spindle.

The tube holder (I dont really know what this bit is called, the area that is just 6mm after the thread but before the spindle) is 3.5mm long and if I made another one I'd make this a bit longer, as it doesnt hold the tube very straight, but it still works.

Fuel is normal BP + 10% metal powder, and I also have in mind using it with a weak sugar based propellant for a model plane Rapier.cz motor replacement.

I have these working with titanium sponge and they leave a great trail, with the silver sparks still visible as the rocket reaches its peak height and burns out.

Just picked up some AluBronze bar and a large 75mm x 75mm x 150mm aluminium block. So in the near future I will be machining up some new tooling out of some nice non-sparking material and a casing to stop the tubes splitting on my 30 tonne air powered hydraulic press. Repeatability here we come.

My tooling arrived from greg yesterday it looks amazing!!! I went for the 1/2 inch and 3/4 inch BP set. Can't wait to try it out. Now I need somewhere to fire it and a good BP comp to put in it. I'll let you know how i get on.

I'm about to make an order with supreme pyro:
1 25mm discount brass rocket tool(spindle, hollow rammer, solid rammer) [15,9€],
1 12mm brass rocket tool (spindle, hollow rammer, solid rammer)[12,5€].

+ Shipping cost 25.5€
+ 5€ paypal fee
=
58.9€

Is it reasonable?

Any comment on the size of the discount tool?

Also i was wandering about the 12mm tool's size. I was thinking of:
spindle size from 5mm diameter on the bottom
to 3mm on the top
spindle length 2,5 cm
The spindle being so short is also good for fountains, right?

Any advice would be warmly received.

Received my tooling from supreme pyro today.
Shipping was faster than expected (it took no more than 10 days from payment)

I received (for 65€)
1 25mm spindle, 1 hollow rammer, 1 solid rammer
2 12mm spindles(1 for rockets, 1 for fountains), 2 hollow rammers (???), no solid rammer.

Apart from the 2 hollow rammers, everything was as expected and seems quite solid.

Tooling aint bad but if your going to make sure she knows what you want. Don't just say 3/4", send a detailed drawing.

I too can recomend wouters pyro tools.

They sent me 5 free tubes with my 2oz rocket tools and a letter too, saying that they were my cousins sending garden tools or somthing

As if any customs worker is going to know what it is anyway

My Greg Boyd stuff has been sitting here doing nothing, had a few CATO's (probally my fault for not making decent fuel) and I've lost morale. Its a lot of effort making a good fuel, my supremepyro gear is good as it has a short core
