I think I have a good aluminum jacket (from a discarded water filtercartridge) from which to make an air-oil separator as shown in Tony's"Firewall Forward" book. Only problem is it has a plastic liner about a64th thick on the inside. Does anyone know of a product that willdissolve plastic without harming the aluminum which is about a 16ththick?DickG.Ft.

Hi Dick,It depends on what kind of plastic it is. If it is a styrene orpolycarbonate, methylene chloride will dissolve it. Try a cheap (thecheaper the better) paint stripper. Most of them are based on methylenechloride. Be sure to use it in good ventilation, unless you want livercancer. MEK will dissolve some plastics, as will toluene, but neither ofthem will work as fast as methylene chloride.If the plastic is polyethylene, I don't know of anything that will dissolveit. You might try melting it out in your wife's oven (wait till she's gonefor a day or so, to get the smell out of the house). Put it in a disposablealuminum pie pan and let it cook at 400 degrees for a few hours. Thatshould do it. Or melt or burn it out with a propane torch, but be verycareful not to melt your aluminum. Perhaps if you wrap the outside with awet washcloth to protect the aluminum you can burn out the plastic withoutdamaging the aluminum.Are you going to be welding the fittings onto the aluminum? Do you knowwhat alloy it is? Some are weldable, some are not.Jack -----Original Message-----

Thanks Jack and Gary. I think I might try the auto salvage yards for an oldstyle oil filter to convert. Still thinking.DickG.----- Original Message -----
