Peter,
Yes a funnel shape allows the sand to flow to the pick up. I've tried it
withour a funnel
and it don't work too good - ie doesn't flow/ fall to a good pick up spot.

Don't filter, however I've put a vacuum pick up spout on mine(just plug on
the old
vacuum cleaner) it eliminates a lot of dust. The rubber eliminates a lot of
rebound
and therefore reduces damaage to the glass/plastic viewer/cover.
You will find  sandblasting suppliers in the yellow (or whatever) pages,
they supply all
mediums, guns, gloves (get good gloves that will last).

Needless to say the good stuff came from America, so you should get the good
stuff
at the right price. Remember timber is fine and in the event that you wear
it away-
easily replaced, my cousin used form ply 3/4", just screw it together, no
glue required.
What do they say - keep it simple !!
