Hey All,

I just built a router table, with an Incra LS positioner mounted to it, and it works phenomenally, however, whenever I have to run a board both horizonatally, and vertically, there is often gaps (64th of an inch or smaller) in between the dovetails on one side of the joint. I know this is nit-picky, but it’s an Incra, so there really shouldn’t be any gaps at all!

I have come to the conclusion that this is because the center insert on the router plate is slightly off keel. I will try to level it with a paper shim and see if that works, but has anyone ever had this issue? I have the Rockler table top, and the Rockler router plate. The center inserts are little plastic parts that seem quite cheap to me…would really like to upgrad to a lift with metal inserts at some point.

Any suggestions would be great! Thanks,
-Josh

Depending on the plate you bought, several brands actually list it as a feature that the baseplate is slightly peaked. I use to know a list of brands which were peaked, but alas it’s just all gone.

-- I'm looking forward to regretting this.

I know this is not your issue, but I will use this opportunity to vent one of my pet peeves. You will find that there is not much uniformity in the size of router inserts. You have a Rockler table top. If you were to buy a Woodpecker router lift, you will find that it does not fit into the cutout. You would have to cut out a bigger opening – which can be messy.

You are, effectively, limited to buying a Rockler lift.

Well, you all are right, I found out through a couple scrap pieces that the “spaces and gaps” only appear on pieces I need to rabbet first, such as half blind dovetails. Apparently the center is noticeable lower by a 64th, maybe even a 32nd, and no amount of leveling can fix it.

I have found that by clamping the board longways to the the right angle sled on the INCRA jig, while setting the height by using the table top (not the plate surface or center insert), which is where I set all of the other components heights, I can’t get a good, seamless fit. But I feel like there should be a solution for this…do I have bad technique?

At this point I am out of ideas, I leveled the plate, and insert three separate times today in an attempt to weed out leveling, so I am at a loss.

Have your say...
