Vintage Dirt Bike Q & A

I saw a old cylinder and head Bead Blasted. I never had anything bead blasted and wanted to know is this a good way to clean up a old cylinder or a head. Is bead blasting only good for outside of a motor part. Does bead blasting hurt the inside of the cylinder or inside of the head. The photo is a cylinder and head that was bead blasted.

There are many types of media that can be used to clean parts...Depends on what you expect the final finish to look like.If your doing a nut and bolt museum resto and you dont want to alter the metal in any way, try using walnut shells,plastic media,soda or a chemical stripper. This usually uses less psi which will cause less damage or texture changes to the metal.Make sure you cover any machined,metal to metal gasketed surfaces with a heavy tape or gasket(so you maintain a good sealing surface) and I would mask exposed studs or threaded holes as well.Also clean and re-clean all the parts that come back from the stripper as to not contaminate your engine or parts during re-assembly. eL
