I'm looking for a star plate for small stars 2, 3, 4 or 5mm. Does anyone have anything to sell to me please.

[AdmiralDonSnider]

Arthur, as I´m currently after a plate for small core stars, I can tell you that Wolter offers them, at least down to 3mm in diameter. I asked for a custom made 2mm plate, we´ll see what he can do. Not quite cheap though.

I'm really looking for a small plate with only a few cavities, so that I don't need a huge (expensive and heavy) press.

 

I'd be satisfied with 3mm stars at four up and 8mm stars singly.

Hi Arthur, if you've got a rough schematic of what you're after for a 4 x 3mm plate, I'd be willing to have a play around with some aluminium plate and brass rod when I get a spare minute.

You're a gent James.

Smallest I can find is this one, Arthur - 1/4 inch, 6mm, but if you make stars any smaller they burn out before the break expands.

Looks like about 35 quid in your money. Chinese of course. I bought several various size star plates and crossette tools from Pyroworks, all excellent, but their rocket tools are worthless.

Would a syringe type pump not be more suitable, http://www.pyrosocie...ooling/?p=56138
I was able to pump out a " snake" of comp them cut in up to size

There are ways of making stars! BUT I'm looking for something that's 100g compliant and makes dry stars that can be fired the same day. I'm also looking for something that can be pressed without a press machine. Screw or lever sounds so much better than a big hydraulic thing. Remember that for 100g of product I'm probably only looking for 50g of stars.

Arthur,

 

if you want to press dry powder to a cohesive mass, you may need fairly high forces, at least an arbour press maybe ?

a small ahnd turned tablet press would work but would be expensive

 

slightly damp composition with a binder you 'll probably be ok.

 

2mm or 3mm stars.................bit small, what are they for..........special application ?

[Arthur Brown]

I'm looking for things that could possibly be made under the 100g rule as we currently understand it. A 2" or 2.5" shell may be possible, but would the ingredients be actually makeable? 

 

I'm reckoning that a large manual effort on a lever would permit the dry compaction of a small star without machinery.

[dave]

a small arbour press, 1/2 ton is about £30..........not too bad

[starseeker]

I have made many 100s of 3,8th stars just using a dead blow mallet Arthur , they dry rock hard and its a easy process.

Ho I see what your after now, any thoughts on casting resin stars ?, didn't brocks do it commercially with thin squares cast on rubber mats, I found this on comps http://pyrotechnics....ocks patent.pdf

I could make "rubber stars" I'm certain the solvent would evaporate in a few hours, but this rather limits the number of formulations.
