Just last week, I finished my router table by adding an insert. I used a 1/2 inch roundover bit and it seemed to work pretty well (3/4 mdf). After gluing some pieces together, I noticed that the roundover cut does not appear to be even all the way through the piece (about a foot long). Because of weather and work, I have not had a chance to check it closer, but hope to tomorrow morning.

What may have caused it to not cut evenly? Anyone have any suggestions to check for? Table/insert not flat? Fence not straight? The router moving the insert some? (insert is not screwed down, only held down by the router's weight (Ryobi) and also the fence on top of it).

Appreciate any help/advice.
Thx, Frank

del, this router table was actually made several months ago (a first project), but I did not buy the router insert and install it in the table until just last week. I did have a problem with the table top. It was originally 3/4 inch ply from H.D., but after sitting around for 3 or 4 months, it did warp. I then glued it to 3/4 inch mdf in the hope of flattening it a little and then screwed the top to the base. I have not checked it for flat, but it appeared to be OK. Thus, my asking if an uneven top might cause the uneveness of the cut. I also had some problems making the cutout for the insert to sit in, but, after adjustments, I finally got it where the router sits in it pretty good. I will recheck everything this morning as soon as it warms up.

I was doing roundovers on 11, 12 and 13 inch square pieces of 3/4 mdf and did not notice this uneveness until I stacked them on top of each other (much like a pyramid).

bob, the bit does have a bearing at the top. I do recall that after the piece finished going by the bit, that there seemed to be a "lessening" of pressure. Not sure if I said that right. So, maybe I did not have an "even" downward force all the way thru? The uneveness appeared to be "even" throughout the cut. I mean that it gradually got wider or narrower from one end to the other and did not fluctuate. Does that make sense? I did get the insert from Woodpecker.

thx, Frank

kp, I did go out and try the multiple passes. That did seem to do the trick. When I did one pass, the first part of the cut seemed to be a little deeper than the back part. I did run a scrap piece through it multiple time (3 & 4) and that evened the cut up so that it looked pretty good.

I guess I don't understand why it lifts it up like that, but I think that was it. The bit is new, so should not be that. The router is not real heavy duty, but is the ryobi 2 hp. Would that have anything to do with it? Thx.

Did you drive down to Flagstaff or just to the area? Been real dry winter, although this past month, we finally got a little snow, probably about 35 inches total (mostly one storm). Year before last, it was so dry, that the bark beetle killed thousands of trees in the area. But for someone that was raised and lived in the dry desert all my younger life, this country is beautiful.

thx, for the help, Frank

Gilbear, I will remember that. This is the first time I've routed on a table. Good learning experience for me. Just wish I had seen the cut "before" I glued parts together. Once it's all painted up, maybe it won't look too bad.

kp, glad you had a nice trip. Even though I live about 40 miles from Williams (I live just to the north of Flagstaff on the way to Utah), I have never ridden the train to the Canyon. Hope you enjoyed it.
