I might be able to help you out with the cover for the wiper. I just need to know exactly which one is missing, and I can make a copy of mine.
It might be a while before I can get it done, though, I have a few things on the waiting list already, but none of them are particularly large projects. I finally got to making a new no-fog mister this evening, I have the block and the extension tube done, just need to make the nozzle, a mounting stud, and a couple of tubing nipples and it will be done. I need it for one of the other projects I've got on my list.
I have not made a set of way covers just yet, but I do plan to do so. I've got some very thin (1/16" or so) rubber conveyor belt on hand, and I am thinking that I should be able to make some nice way covers with that stuff. There's another item on the waiting list!
