Question: Recently purchased; could not remove screws to mount center guide pin. Any suggestions?
Document: One of the reasons I purchased Porter-Cable 42690 Edge Guide was the customer reviews; many customers seemedgreatly satisfied with the item. I have been using DeWalt DWP611PK Router Combo Kit. Till I got the Edge Guide,I was concerned if it could be attached to my router since the manufacturer of my router and the plunge base were not the same, but the shortest rod was easily stabbed to the plunge base. Also,the screws to be installed to the base were enclosed.
I purchased this product with a new router hoping that it would provide a simpler, more portable and less expensive solution than a table mount for working around edges. I've been disappointed in two ways. First, the mounting is not nearly as positive as I would hope. Even with the screws firmly affixed, there is still a small amount of play between the guide and the router. This does not inspire confidence, and creates accuracy problems when using the guide fully extended.
I really like this edge guide a lot. The only trouble is that the screws that mount it to the router don't come with either the router or the guide, and it's not a size that most people have in their shop. It seems to be a metric M5. I had to go chasing around to find the right screws.
I purchased this guide over a year ago and have used it many times. As is stated in other reviews the guide is pretty awkward, due to it's length. This could be useful for a dado or something in the middle of the panel but have not used it for such a task yet. My main complaint with this guide is the absolutely flimsy sheetmetal that does the guiding. I have obviously attached a longer piece of plywood to this - but it is just flimsy.
This is a really accurate easy to use router guide. I wish I could figure out how to mount it to my skill saw for breaking down plywood.The guide is easy to use, pretty intuitive, and does a very good job of what it is supposed to do:  guide the router.I've used it with Porter-Cable 690 and 890 series routers and it is a cut above the old style with two rods.
I bought this guide for use at work. I've had the same guide for about five or six years now at home. The pin to make it work as a circle guide was lost about a month after I bought the one at home.
I wanted a guide that could be adjustable and accurate. This edge guide allow for fine tuning using two thumb screw stops. It also was a good price.
I am impressed with the quality of the guide and am pleased to find that the quality of the Porter Cable line has held up over the years since I purchased the router. Amazon's response to my order was timely and delivery just in time to meed my need for the tool.
I love this guide. It is very precise with no slop. Just mount a piece of wood on it for more stability, and you are good to go.
I have other Porter Cable products that work well. The quality & design of this edge guide shocked me. It could have easily had more than an additional 2" of travel with a simple design change. Or you could shorten the beam by 2" and have the same usable travel with a design change.
Answer: yes
