Sub Base:
I was needing a larger diameter hole base for the router and this one is nice. It not only allows for larger diameter bits but also allows me to view the work area. This is great even for working on inlays and close area work.
Poor finish:
This product is generally what the description says, but it had a very rough finish on the outer diameter. It wasn't a knurling, it looked like there was some tool chatter when it was made. I'm surprised at this low quality. I had to put it on my lathe, true it, and flame polish it to get it the way it should have been. It was easier than returning it, but I shouldn't have had to do that.
A Must Have:
Definitely something no woodworker should be without. I can't believe it doesn't come with the router itself.
A round piece of plastic.:
One problem people have with the Porter-Cable router base is that the hole in the base is too small to accept some of the larger diameter bits that are now available. The hole in this base is larger than the hole in the standard base. However, the Porter-Cable bushings that work so well are fitted for the standard base opening.
It might as well be said that if you are at the skill level where you are using a router you are at the skill level where you can make this yourself. All that is needed is some 1/4... more info
