DYI fume extractor ideas

[grsthegreat]

I try and weld outside the door but MIG has this aversion to wind!

It doesn't help that there is always at least one rag, sopping up some oil spill within spark distance!

isnt it amazing how that these rags show up even if i dont remember buying rags

My welding buddies tell me about the times they would fill an empty milk carton up with a mixture of acetylene and oxygen. This would be left conveniently under someones cutting area while they were cutting steel with a torch. For those that don't know this will explode with a loud bang when the sparks or cutting slag ignite it.

now thats just mean......lets see i have everything except for a milk carton.

I used to...in my mean old days.... walk up behind en electrician working in a dead panel and pop an air filled bag behind them while they were concentrating hard.....they clear some air. I wouldnt risk it if panel was live though.

In high school electrical shop, they used to insert capacitors into outlets that would blow up when the teacher turned on the main switch.

In the shop we use to blow up old coolant containers with compressed air whenever someone was working around an airbag system.

Some guys use to jokingly tap the inertia sensors while walking by, one day it actually set the airbag off while a tech was working in the front seat, he never did find the cigarette he had in his mouth..........

I didn't read the thread. When I was practicing TIG I made an extractor powered by a free bathroom fan, 4" PVC and a couple of 45 degree elbows out the small shop window.

I love dese threads on air handling.
Got a question for all de exhaust fellows, what you doing to keep exhaustin once de room goes negative pressure?

Wonder if dis thread gets all de way to forward incline/reverse incline and flat blades on de fan and loss of efficiency as de blades coat. Give ya a free hint, DON'T spend time tryin to use a condenser fan from a HVAC unit to move air unless ya use a proper nasal to deal wid tip vortexes.

Far as blowin tings up, get back ta me when ya ready to braze spark plug bosses into 55 gallon drums lef in de sun to vaporize de contents all day. You kids need some learnin.

You kids? Com'n man! Negative pressure... sure open a window. While I want to appreciate your contributions here you are wearing on me. Let's be constructive not condescending.

There's always that sorta dude, you know'm sayin?!!

Anyways, fan came yesterday, thank you amazon prime shipping. Happy to report that it's very quiet yet powerful.



Then, it was over to HD, where I spent a good 40 minutes staring at the hvac isle, decisions-decisions on how to plumb this thing. I bought a few extras so I would have some options, will return what I don't end up using.



So altogether, fan and all, minus what will be returned to HD, around $100.

Nice! I saw a couple youtube vids of that as well, for soldering fumes.

For fire reasons and also metal contamination on wood projects, I hate having a mixed metal/wood shop. I scrapped plans recently to build a new shop with dedicated areas due to economics of the project.


I procrastinated for years for the same reason. What would have cost a lot, now costs even more. My dream shop is now 1/2 the size and will be over $100,000.00 when finished. Now at 72, I have the feeling that I left it too late and won't get enough use of it. I'm running out of time. Free advice is worth what you pay for it.
