Thread: Painting blue styrofoam
24/01/2012 10:13:55
I have sorted the cutting now by using a brass tube - shampered correctly at the end and lubricated with teflon spray does the job nicely, lets me turn out 25 of these a minute.
 
However I am sure the material I have is not right, the cell structure doesnt seem to be dense enough, the tube on the cutter gets nice and hot and polishes the surface and when painted it gives a reasonable finish straigh off but I'm trying to avoid having to resand and the repaint... I'm wondering if there are other grades of styro available?

The problem I have with the hot wire is getting a perfect circle it seems to distort or I wobble on the way down! I have looked everywhere on the web for a styrofoam dowel but it doesnt seem to exist! If I had a tool to cut the styro dowels with hot wire then I would be away as the heat seals the surface as drilling them just gives a rubbish finish...

Thanks for all the replies guys it really is appreciated.
 
I am trying to make basically some struts that are 10mm tubes and 100mm long, I am drilling a hole right up the middle and inserting a 3mm bamboo stick for rigidity. So I am then left with what looks like a column made out of styrofoam.... I am drilling these shapes out using a high speed drill with a steel tube (shamfered end) - but the finish on the plugs created is poor... sanding them still leaves an unsatisfactory finish (I have cleaned the tube and also lubricated while drilling - still not good enough)....
 
When I cut the foam using a hot wire obviously this leaves a perfect smooth surface as its being melted at the same time as being cut.... if only I could cut the perfect 10mm column using a hot wire I would have what I want.
 
I presume there are other grades of blue styrofoam - perhaps I'm using the wrong material to start with as its to soft? Anyone with experience can help with this????

Hi Guys and girls,

Just joined your forum after being a lurker for a while.

I'm hoping that someone can help me with a dilemma - I am having a hell of a job getting a good finish on a panel I'm wanting to paint. Its made from standard blue styro but having cut it and sanded it to death it looks really fine to the naked eye - but when I paint it I cannot seem to get a nice smooth enamel type finish without any lumps bumbs or grazes showing.... can anyone advise whats the best paints to use so that I can dip the panel and get a really high quality paint finish without having to keep rubbing down and panting and then putting another coat on - surely there is a way to dip it and get a nice finish straight away. All help appreciated.
