Bench Paint Booth Build

If you've followed my new members intro/post then you have a good idea of where i'm starting and what i'm trying to achieve at this point. While I am waiting for parts to rebuild my compressors, I've been figuring out what to do for a paint booth. Then i came across @Spinner Video in the member video section and was impressed with the layout and in particular his JC Metal bench paint booth was perfect!
My plan was to take this design (JC-B-4) and use the dimensions to build it out of 2x4's and 1/2 plywood and leave a couple strips of plexi-glass for lighting on the top and sides. Instead of the tube axial fan, I plan on purchasing a squirrel cage blower to save some additional costs. There are a couple of reasons for this, 1) I'm just starting out and have a large learning curve in painting and figuring out HVLP guns, 2) I will be painting small(er) parts, 3) At this time it's only a hobby, i have limited space and money. With that said, i know these are NOT explosion proof but with the small amount of painting, the planned filtering, and the fact i'll likely be starting out with water based paints I should stay well below the LEL.
Now for some of the design, the largest airflow blowers I've come across for 1PH 120VAC are the Dayton 1TDU1 (990CFM) and a 1TDU2 (1200CFM). I WAS leaning more towards the 1TDU1 as it draws almost half the amperage, but by the calculations I've seen this may be a quite under sized since the booth opening is basically 4'x4'. Even the 1TDU2 is a little undersized so i'm going to shrink the booth dimensions to 3'6" and should be about spot on with the minimal airflow of 100 FPM (12.25X100=1225). I'm going to mount the blower on the bottom of the box (behind the filter section) and transition it to a 6" duct to run out and under may garage door. Since this is being done in the 3rd bay of my open garage, i will also be putting up a divider curtain between it and the other 2 bays. This was the plan anyway for HVAC controls (garage is currently non heated) as this is my working bay will the other 2 house the family vehicles. The divider curtain should keep any over spray that may occur contained to the area.
I'm actually also planning a block of plate for in front of the filters and adding another 6" duct connection with block off plate so when i'm not painting, i can create a hood vent over my dip tank and utilize the same blower. I think i will achieve this by actually adding hinges to box on all sides that fold in and block the filers, this will also allow me to save some space in the garage when not in use! Of course the whole thing will sit on some nice casters to move around. More to come!
I'll likely purchase the blower early next week so i get a good feel for the size of the box behind the filter section and can layout my dimensions and purchase the wood! I'll do my best to document the build for others, something i've never really done but i'd like to contribute to this forum as it has been essentials in my endeavor.
I've put a lot of thought into the build and i think it will work for what i need at this time. I would love to get some feedback and criticism from the forum.

If you are going to spend this much time planing the build, It will take a tons more time to build it. Time is money, work more hours at your full time job, save some money and do it right. Maybe get your feet wet before you build all this stuff, that in the end doesn't work that good and will be replaced if you continue with this "hobby".
And if you decide to go down your path, buy used stuff and piece it together since funds are tight. I feel you are over thinking a lot of this.
I found my booth on eBay for 800 bucks plus delivery. It arrived ready to plug in, though I added the duct work. There are good deals out there if you're patient. Plus with it being a manufactured unit, I could at least break even if I ever wanted to get rid of it.
Thanks for watching the video.
It came with a box of expanded paper filters, which I feel are inadequate based on the amount of build up I see so I'm going to added some basic pleated filters behind them. Once I use up what I've got then I'll probably go to the extra density fiberglass paint arrestor from boothfilterstore.com
