Woodpecker lift..
I like mine because it is a fast set up, one quick pull and you are very close to where you want to be, then crank it left or right to do the fine adjusting. I was running some oak through the router to make stile and rails, but when I put the two together I was off slightly on every piece. Nothing sanding can't fix, but I would like it to be closer to flush than it is.
I set it up using pieces that I had already run through and they where flush in the dry fit.
I did have to remove one of my pins in the router (Porter Cable Model 7518) that the fixed base is threaded onto in order to get it to fit so it would adjust freely up and down. (It was hitting the threaded bar when you cranked it up or down). I simply found the pin that was the problem and pulled it out with side cutters. I figure I can easily replace the pin if need be.
I also had to remove the tension springs plungers that keep the plate from sliding during routing because it was such a tight fit I couldn't seat the plate in my extension wing on my table saw. The plate doesn't move at all, and it also gets screwed down, so how can it?
All the stiles that I ran through it are all the same, but the rails differ slightly.
I guess I'll have to play with it even more.... heh
