2011 forum posts	I must admit I'm not sure what you want, so ignore this if not relevant. How about going the other way round, find a tube of the correct bore, very clean, lubricate lightly, fit the core inside,. blank one end then fill with foam from a can, close the other end of tube, this will make the foam denser. Push out the foam slug. Different types of foam are available. I know this works, done it.

4 forum posts	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?

2011 forum posts	There are lots of different grades, but no idea where to get them in small quantities. The average HGV freezer trailer might have 4 grades, including very dense structural grade. Might be worth trying a breakers yard?
