For those of us that use the manual filter wheels, one of the problems is that the wheel is open where you push to move the wheel to change filters. This allows dirt and dust to get into the wheel and onto the filters. I have been thinking about a solution for a while and came up with a simple one.
I used self adhesive felt and foam available at Walmart in 8x11" sheets for about $1 each.
This stuff sticks very well and is easy to cut an apply.
Removing the front cover gives access to apply the felt and foam.
Place one strip on the inside of the front cover so that when the cover is installed, the wheel rubs against it.
Cut a piece to fit the opening on the other half and use a second piece to make it thicker and act as a rubbing seal. Then I place a small strip of the rubber foam below the felt to force the felt upward against the wheel, keeping a small amount of pressure on the flap.
Next I added two small flaps at each end of the opening, where there were two small gaps. I put a piece of toilet paper on 1/3 the length to cover the adhesive and the stuck the flaps to the body of the filter wheel. This paper keeps the adhesive from sticking to the wheel when the wheel is rotated.
The filter wheel is now sealed and with the TV focal reducer on the front, there is nowhere for dust to enter the filter wheel. A clear filter would also work fine for this.
