To all,
On the subject of sand blasters, I made my own; and although I made the case
ourt of stainless
steel, my cousin did his out of timber (with a perspex top) - it cost very
little and did the job vey  well.
If your worried about sand blasting the timber, stick a thin layer of rubber
on the area in question.
If you put the money into a godd nozzle, you will have a good sand blaster
for life, if you but the
cheapie nozzles - well, it may last as long as you need it to !?

Dennis Hayes at Hayes rotary engine cautioned about using abrasives that
might stay in the engine and damage it. So use only crushed walnut shells.
