Well i just spent all morning trying to roll a batch of stars with the Spray gun.. and basically i have wasted about a Kilo of comp ..I weighed out around 10,000 cores coated them with Bentonite clay... thats the easy bit.. then added them to my tyre roller , Now the spray gun did still blow the cores away but i managed to get them wet.. .. I started adding small increments of powder..spraying powder etc...

It seemed to be going ok but i noticed it wasnt picking up the powder very well so i wetted them more..But the powder didnt seem to stick ..So i got them really wet and just as they start to clump i added a tiny bit of powder... normally this works ok.. but in this case the powder just seemed to build up on top edge of the star pile .. i tried allosorts but the damn powder wouldnt stick...

Last week i used a hand sprayer and they rolled up dead easy perfect liitle balls..rock hard..But with this spray gun no such luck?.. also went through lots of acetone nearly a litre? the spray gun gobbled it up.. not very impressed at all...I am wondering why should a hand spray mister work ok? but the spray gun didnt ?

So i have just ordered one of those Solvent spray/misters from atomizer and hopefully will have more success..

Wow, I must be so fortunate to have a nifty little old fashioned copper mister. It leaks a bit, but still, it is better than it dissolving...

Aceton is the stuff used on visco fuse isn't it? if so is it essential to use it on stars?

Acetone is a solvent. It is neccesary to use it, or a similar solvent, when making stars from compositions that are water sensitive, such as magnesium based comps.

Yes it is used to make nitrocellulose laquer (NC) which is used to apply a water resistant coating to visco fuse. It is not the material that forms the coating it is simply a solvent for the NC.

I'm not sure if it would be acetone proof or not, but ive seen glass/metal misters at department stores in the garden section. i think theyre meant more for looks than to be used, but hey, its worth a shot. if i remember right they were like $3 here in the US

Well i got the Solvent sprayer this morning it cost just over ?40 , its 950 ml capacity The actual trigger head is all metal construction and i have sprayed over a litre of acetone through it and it seems to work perfect! ..I have left it for a few hours gone back and sprayed it and it seems ok..Normally on the other spray heads i have tried after a few sprays the trigger tends to stick, this has a nice possitive feel to it....

Its a bit to cold to try rolling some stars so i will give it a go when it gets a bit warmer...

So anyone looking for a acetone proof sprayer this looks promising?.

not the cheapest thing tho.

Cheaper than buying a new spray gun every week.

not if you do one big batch at a time, and use maybe 3 or 4 guns a year.

Airbrushes are often of all metal construction and i have had various solvents through mine.
Not sure if the size i up to what you are doing though.

Yes but it is nice to dig up an old thread or two and some of the older members.
