looking for a cheap easy way to basically vent the fumes from the casting pot to the outside. i can go thru metal shop wall easy enough with ductwork but need ideas on fans, hoods, etc. thanks

  A box fan literally in a box at the end of duct work will give a excellent draw. If you attach the inside duck work into a stove hood to ketch the fumes, the fumes will be drawn out side.

Hey sergeant69

    A good quality range hood will work for most applications. Fluxing and rendering should be done outside and considered as a different procedure than casting. Light fluxing can be done in the casting area and the hood will be sufficient. Normal casting temps have little lead released. Good quality hoods have filters which can be cleaned regularly, most have variable speed thru wall fans and come with a light. Exhaust thru wall must have proper intake vents as well to be effective. High quality units are easy to rebuild, parts are available and simple to upgrade. A helpful hint is to mount securely as it tends to double as a shelf. Don't go cheap here!

                                                                                                                                                                                 Roy

I used an old blower from a furnace and 6" flex vent pipe.

I put in a roof window - no fan needed!

But an exhaust fan for a shower works well too.

I bought a box fan for $4 at a yard sale, 16x16, and just set it in the window. It is not fumes you have to worry about, but the dust, metal oxides.

In FS 267 I wrote an article about a ventilation I made, it may or may not work for you. It cost just less than $60 (less depending on what you have on hand) and is very efficient. Below are some photos.

Gunarea,I know this is off topic but is this a Dillon RL300 in the photo?

If so,we must be amongst the last half dozen guys who still have one.

Mine is still going perfectly strong without a glitch.How's yours doing?

Hey Qc Pistolero

    Mine was sold to me by Mike, has original tag and the original individual typed instructions. I have gifted two other of these presses. My press has produced cast bullet ammunition that has allowed me to win multiple Florida state gold medals. On a weekly basis it still is my main loader. Dillon kinda abandoned us RL 300 owners. Tool heads were a stumbling block for years. Over a million rounds have come off my press and I wish I could age as well.

Mike also sold me my first Dillon, an RL 1000 in 1980? we had several discussions about the swager didn't work so great. he was thinking about a rotary cutter but never did it.

David Reiss...........son is a contractor and is in lowes, home depot etc on a daily basis. best he could find is a 25 cfm bathroom vent. he said that wouldn't even clear out a mouse fart in an outhouse. since we are in the austin area (one hour south) building supplys are either nil or cost  5x anywhere else. anyways, i just went with one on amazon that moves 800 cfm with 20 ft of flex duct. overkill but we have a tractor for sale and will take $200 from that money. we are always moving $$ from the left hand to the right and back anyways.
