Grinder with Sparks

[SilentPartner]

I'm setting up a 2x72 belt grinder to grind knives.   A lot of guys just put a 5 gallon bucket under the grinder for the sparks and dust to fly into.   I'd like to create some suction under the grinder and I'm concerned about the sparks.   I'm wondering if anyone has used this system in my application?   Maybe by incorporating water on the bottom of the collection pail?

I would be hesitant to make something from wood to use with most metalworking, but you could possibly make an all-metal separator.  If you have the metalworking skills I don't see why this wouldn't work.  If you just put a bucket with water at the bottom but have a wooden separator you might get hot metal pieces stuck in a wooden corner in the baffle somewhere that smolders for awhile then catches fire.
