Trying to rebuild a Vermont Castings Defiant Stove. I did the same procedure, maybe 15 years ago. I struggled with a wire brush and a brush on a drill to clean the cast pieces and the grooves that need to fit together.

I have toyed with the sand blasting idea. Does anyone have any input? What grit material would be most suitable? Other ideas?

Thanks,

Terry Ready

Hey man just an idea. I do a lot of outside blasting too, I just tape a piece of cardboard on the top of my hood. Not very effective I’m on my back but does the job when I’m on my feet.

Was wondering what would be the best sand blast media for cleaning out knots in pine logs.I know sand seems to be too agressive. I finish off by sanding with 180 grit, but cannot get into dips and knots with sanding.Is there a media that would work for this situation ?
