Am I to be frowned upon by the 'traditionalists' for doing this?
I use kiln dried sand - the sort used for dressing block paving, cheap and plentiful and fine enough to make the parts look like new without wrecking the wood or felts. For obvious reasons I keep the blast well away from hammer noses.
If I get slated, will it stop me?
Of course it will.
