I am brand new to this forum and this is my first post. I don"t often post on a forum but enjoy reading and learning. I've been a woodworker for a long time but have recently run into a new problem. My jointer is broke down so I have tried using my Delta RU50 overarm router to edge joint my wood. I replaced the wood on my fence using MDF and everything works fine. However I am having one problem. After I have jointed and edge I find I have a very slight arch in the edge of my board. The arch is always in the middle of the board. I have made every adjustment possible but to no avail. Can anyone explain to me what you think is causing my problem.

OVERARM ROUTER AS A JOINTER

If you're using a router table, or overarm router, as a router table, you need an offset in the fence, and the fence needs to be correctly aligned. Here are a video and article to help you with this.

Thank you George for the response. The offset fence is the one thing I forgot to mention. I do have my fence offset exactly 1/16 of an inch. That is what baffles me. I still get a slight arch in the middle. I have checked it with several differant straight edge items, my saw fence, rulers, the blade of my tri-square, etc. I simply cannot figure it out. I guess my answer may come in try, try again, ha ha. I will let you know when I get it "straightened" out.

Since you've got an offset in the fence, here's another thing to look at. If the edge is convex the outfeed side of the fence may be too far forward. Try moving it back, so you're taking off just a little more material, and see if that helps. If it's way too far forward the end of your board will bump into it, but if it's just a smidge too far forward the edge will climb up on it and you'll create an edge that isn't straight.
Let me know if that helps.

George, thank you for the input on my overarm router / jointer problem. Tonight I went to work on the problem trying everything I could think of. Finally I took a feeler gauge to measure the rise in my edge jointed oak. The rise amounted to .014, not much until you want to glue two of these edges together and they act like a rocking chair rocker. To shorten the story I solved my problem with two thicknesses of duct on the end of my outfeed fence closest to my router bit. Problem solved! Now my edge is dead on and there is no gap from end to end as I lay it against my table saw fence. Of course it is a temporary fix but it works perfect for the short term. Thanks again for the inspiration to investigate further.

Oops. My 6th sentence in my response should read; "-------with two thicknesses duct tape------"

Nice job troubleshooting and resolving this, Oakleaf. Before I had a jointer I used to use my router table for jointing and it took a long time to get it set up properly, but once I had it tuned, it worked pretty well. With a long solid fence (mine was neither) it could work great.

Thank you Paul. I really enjoy using my Delta overarm so when my jointer went down the overarm seemed like a natural to come to the rescue.
