We did build it and it worked perfect.
Pictures didnt get posted upon finish of the project as I had to settle up a divorce, so between keeping the shop running and the divorce I was a bit pressed for time, I sincerely apologize.
What we did - On ours we did wind up cheating in the end though because it took too long for the unit to get to a point that would fight fifty five degree weather which in alls reality is what most of you will be fighting so we wound up using a special tight aluminum cooling fin set to get the output temp of the fog down to a temp gun measured 22.6 deg. hose output degrees verses the cooling fins from the factory unit that only got it down to 43.1 deg. MAJOR DIFFERENCE!
With the unit we built in the end it takes about a half an hour to really get good and cold so you dont have to take breaks but the fogger we hooked up to it was a American DJ 1200W.
The first version inital cost was $136.00 in supplies if you count the unit from wally world and it didnt look too horrible but the performance was mediocre and the wind could still catch it and blow it away fairly easy.
The second version where we used the special cooling gate added a extra $112.00 and another ten in redoing the air passage way.
So to do this project in terms of making not only cold fog that hugs but cold fog that condenses and packs its self tighter the extra $112.00 for the cooling gate ( which is made locally here in Louisville ) made it in my eyes a worth while project for you guys to do.
My personal laptop and camera walked off in the divorce that had the pics of the project as did a whole bunch of other stuff so I kinda feel like I owe to you guys to do it again.
I did notice something that made it a lot easier / faster once we got going, a pop rivet gun, we started doing tack welds with the mig when we first started but then I realized not all you guys own a mig so we looked around for the next best thing that most of you guys would have, the pop rivet gun.
I have no problem with you guys and gals calling me with questions on where to find stuff or how to get through any issues as long as your physically attempting the project and your some what dedicated to it. 502-836-3125 im usually in the shop from 11am - 1am seven days a week ( now that im single LOL! )
