    How much will You spend?

    And do You have the space?

    If You look around You can purchase used professional equipment.

    down draft table

    smoke / fume collector

    etc

    I picked up used Torit equipment, a 4' X 5' down draft table{a DDHV45], a portable fume collector{a Porta-Trunk] and a vacume system for MIG/Flux core guns{a two gun MINI-TRUNK unit] all three for less than $3,000.00{could not have purchased the materials for this price] If purchased new the 3 items would have cost over $20,000.00

    Torit makes a welding bench very nice but expensive around $10,000.00 new

    see their URL at;

    The also make the Porta-Trunk;

    Torit current fume collectors at URL;

    Also take a look at MicroAir, the URL;

    partical seperator

    they make a seperator for large pices that mounts on a 5 gal. bucket.it is setup to catch the big pices in the dust colection system for wood work but if you put an inch of water in it you could catch hot grindings. then just run your shop vack in 1 side and the other to your grinding stationwith water in the bucket it would catch everything and your shopvack would be fine you could put a lil water in it to if you were worryed.i'll find a pic or draw 1 if you need.
    good luck

    well, flamables(thinner, etc) need to be kept in storage, not out in the open.
    just keep rags out of the way. the grindings will cool before you can vac them.

    put some flexible hose on the exit of the bench grinder/sander. run this down into a bucket, that will get most of it. you will never get it all.

    What is the best way to deal with hot material removed in the grinding process. I'm concerned about the possible fire hazard just letting the shop vac suck hot material in.

    I recently made a rolliing table for my 2x72 belt grinder on one end and an 8" Baldor grinder on the other. I would like to have a means of colleciting as much as possible while grinding and would like to build some part of the collection system into the table. Any suggestions?

    I worked in a shop a few months ago that had a portable exhaust system. The vent hood was ajustable and the whole thing was on wheels. Used mostly for sucking fumes in close quarters. Would not work for entire shop. Exhuast fans and open doors are what I do. Grinding just gets cleaned up before it gets out of hand. I'm somewhat of a neat freak. I don't do clutter wery well.

    Eicon,

    Looks like you're dealing with two separate issues - venilation and dust collection.

    The ventilation part should work with just a good exhaust fan and enough of an opening in a wall near the floor to allow as many CFH to move in as the fan can move out.

    Dust collection is another matter. It usually takes a ducted system with ports a each work station where you want to collect the dust. For grinding debris, you'll need some form of enclosure to catch the chunks and funnel them toward the collection port. As BlownS10 suggests, an enclosed space is often the easiest way to manage that process, but then breathing air becomes an issue.

    I wish you luck. I settled for a deflection screen around the grinding area that I can remove (space problems) whan it's not needed, and frequent applications of the shop vac!

    a clean welding shop = one that has not been used yet.

    if i had the option, i would have a dedicated grinding area, enclosed. and require the user to wear a filter mask. and gratting on the floor to keep shoes clean, to not track shavings all over.

    fumes :
    open the door/s window/s. during winter, have a vent fan to outside, and only turn it on when needed. most of the time there won't be much of any fumes. unless your doing something like fences, with galvanize.

    thats what i would do.

    what i do now: keep the door open, and shop vac the floor a lot.
