I had previously had a problem getting my spoilboards to stay flat. I went a head and siliconed the perimeter of each onto my plenum, and it worked great. I have since seen a problem with slight cupping in the spoilboard. I attributed this to the fact that i only glued the perimeter and nothing in the middle. And here is where the problem starts.
I went to put on a new set of spoilboards. When i pulled up the old ones it grabbed my plenum and took it with it (see pictures). To answer the question in my previous thread in this catagorie silicone will hold very well in my case a little to well. I now have to figure out how to install my new spoilboards. The section that was ripped off with the old spoilboard varries in depth from 1/64th to 1/8 and maybe a little more. Here are the solutions i have come up with so far, with problems for each.
Fill void with silicone and dabs on every 4th tower then set pannels in cover with plastic and turn on vacs. I worry that the vacs will just suck the silicone out of the void and into my plenum.
just silicone the edge around by the aluminum channels and on towers. With no support around the edges the board may become squishy, or could cause an initial bow.
Repair damaged plenum, probably with bondo then install spoilboards like before with dabs on towers. Pain in the but to do all that bondo work and also not sure how flat it would be or how to flatten it to match the height of the towers(channel would get in the way).
Between initial calibration and general use with the occasional oopsy i wanted to switch out the spoilboards now while i had a slow couple of days. I want to rebuild the plenum but dont really have the time or desire to do that now. At the same time i dont like the idea of having to worry about my spoil board causing problems with upcoming jobs.
