Mushpunx Laminar flow hood build log *completed!!* 2

Edit 1/25/2019 I lost all the photo's relevant to this build. This month I will be building a new (smaller) hood and I will start a new build log. It's been a few years, and I know much more about flow hoods haha
Hey all,
So building a hood finally. Its a work in progress I figured I'd make a little log for comments suggestions etc
So I decided to go with 18X24x6 filter, it should work well for my purposes I was originally going to go 12x24 but Im sick of being sloppy with G2G in SAB klinking jar lid together on accident etc haha so the taller works in my favor.
The filter I bought was decent price and its 18x24x6 1" static pressure

The blower I got for 99 bux, free shipping so I feel it was fair. I know you can get furnace blowers and whatnot for cheap but this seemed like an ok price for a brand new blower.
The blower is 549 CFM @ free air
Matching the blower to filter was pretty freaking confusing at first, now that I get it I feel less retarded about it but I wouldn't have managed so well if it wasn't for folks on this board, namely Madchef, thnx dude!
So I sprung for hardwood, these are edge glued so theyre better than particle board but cheaper than a solid sheet. Its nice Aspen panels, I bought 4x4 boards for under 20 bux, decent price I think. Fair enough

I'm no carpenter so just figuring out how to cut a proper straight line with a circular saw took a bit of youtube watching haha, I cut my top, bottom, sides and back boards and fitted them together with wood screws. I drilled pilot holes first to avoid cracking the boards.

I used two clamps and a piece of scrap 4x4 to hold it together, again I'm no carpenter it took me forever to figure out how to do that ahahaha n

This part has proven the hardest so far for some reason, fitting the furing strips in the proper place inside the box. I used 3/4 by 2 inch scrap wood for this, it took a lot of adjustment to get the weather stripping on the filter to press up against it properly. I used a piece of cardboard the same size of the filter and it made it alot easier.

So tommorow I'm going to cut my hole for the blower in the top, cut a bracing to bolt the blower to for support, and install the blower. Then I'm going to build a prefilter housing to go over the blower.
Finally I'm going to disassemble the whole thing, wood glue it, silicone the fuck out of it,counter sink the screws and put the filter in place and add trim slightly overlapping to keep the filter snug
Saturday: Ok so today I installed the blower, I measured out a square just a hair under the size of the blower mouth. I drilled corner holes and cut out the square (albeit sloppy) with a jigsaw. Next I cut two strips of scrap Aspen to fasten underneath the blower to bolt in for extra support

Tommorow Im going to build the housing for the prefilter box that is going over top the blower

If you can find the hepa and blower at a decent price the rest is a cinch!
Well... if you know what youre doing with carpentry. Its been a humbling experience for me

So today I started building the blower housing

I put two strips of scrap parallel to the blower to attach the pre filter box to.
Then I built the pre filter housing, I put a strip of scrap around the inside of the housing to hold the pre filter up, then tommorow I will make a moulding to go over the top to hold the prefilter in place

ThAnks man! Hell yea Im stepping it up haha

So I just put a strip of wood around the top of the prefilter housing to sandwich it in between the two strips. I had to cut my prefilter down to size to fit but its a good filter and I dont think cutting it messed anything up
So now I have to counter sink all the screws so they sit flat and cut the strip of molding that will fit over the lip of the HEPA
Questiom: I made sure the screws were solid, and im going to silicone the cracks, think I even need to wood glue? This thing is solid I dont know if its worth the hassle?
Thx!

If your nails are holding up and you can shake it around a little I don't see why you'd need the glue. Flow hoods don't produce a lot of movement. As long as it can stand the vibrations, you're good

And also, silicone is a little workable (if that is the right word, English isn't my strong suit) what I mean is, it will move a little and not break, so you should have some leeway when it comes to stability. I don't think wood glue is all that necessary. 
It looks like a good piece of work so far.

Yea workable is the right word, what is your first language? Your english is better than most of the Americans in my neighborhood haha (I live in the ghetto). I have wood glue but man that is alot of clamping and waiting, I think its solid enough the thing is like a rock haha I doubt I could break it

Ok so new question! I need to wire the blower. I figure Im just going to cut an extension cord that has a ground wire.
But Im a little confused as to how the wiring on this blower is set up. I really dont want to blow my motor. I kinda figured it'd be a simple red to red black to black but it looks more confusing
Thanks!.
Ok

Yea? I have a big bottle of good glue Im gunna at least see if its something I think I can do, I only have a couple clamps so everything's been kinda tricky.
If anything maybe just for extra seal

Not for a seal. For sturdiness. Buy some more clamps. You can never have too many tools.

It's Danish. And thanks, I do my best to not destroy the language. 
I used to work kinda as an electrician attaching washing machines, dry tumblers and ovens and stuff like that, not like an electrician that could plug a house to the net or anything like that, but I still have some experience with wall sockets and attaching the right cords in the right places.
Of course, your net is probably not exactly like the European electrical net, but I would think it works sorta the same, if not then I hope someone will correct me. 
It doesn't matter if you attach the red to the red or if you attach the red to the black. What matters is you don't attach the yellow/green to any of those. Even if you accidentally did that, it would only blow a fuse. It's only when you have multiple choices that it gets tricky, for example it there were a red, black, black, blue and yellow/green. Or maybe even black, black, black, black, blue (this happened to me once).
But for wall sockets, that usually isn't the issue. Just put the reddish cord with red and blackish with black and then attach the yellow/green to either of the yellow/green screws. (the yellow green is there to make sure that if lightning hits your net, then it has a connection to the earth and the appliance won't melt its cords and fuses.)

Well what's actually got me confused is there aren't any loose writes to connect to, there's a yellow green wire that connects from one screw to another which Im guessing is a ground wire?
The other two wires attach to a box, maybe a capacitor or something.
Do you think those two screws on that one box are terminals?
In which case one wire to each terminal and one connected to the yellow green for ground?

There should be somewhere on that blower where you can attach the two wires. Can you get the black/grey foam out of the black box? I think that is where the wires should be connected.
Can you get that grey box detached from the motor? I also might be in there.
They wires need to be connected some place where they can't be in contact with each other. So those two screws can't be it. It has to be somewhere behind them or somewhere else.
