Dove tail router jig

Just to let you know, you gave another answer to an unasked question of why should I buy a router table top, and by tacit understanding why a good solid mounting is required for that top. (similar to a wood working bench) or a good reason for a one inch thick mdf table top

Thank you for the heads up.

I have just returned from Rockler. The do have an old router plate insert that will work. Being old they did not have it the store so I have ordered it ($8). Next I will check for flatness. I totally hear you about DT's being finicky. If all looks good and the Rockler part fits, then I will buy the Leigh jig. If my router table is NOT flat, I think I will go buy a different jig (Porter Cable 4210 maybe) and my hand held router which was the setup I used on my defunct Rockler dovetail jig.

There you go! Keep us posted.

Here is an update. I received the Rocker router plate insert in the mail Friday. It does indeed fit which means I can use the guide bushing that is required for RTJ 400 jig. My router table appears to be totally flat. It was made of 1/2" MDF and 3/4" MDF glued and screwed together with a high pressure laminate attached to the top of the sandwich (all part of Norm's design). There are leveling screws underneath the 4 corners of the router plate which I tweaked just a bit to get the plate totally planar with the sandwich/high pressure laminate. Bottom line: I am ready to suck it up and buy the Leigh RTJ 400.

I will send one more update after I have made my purchase, read the instructions at least twice, and verified that it all works for me.

Thanks to Leon and all in this group for the valuable help..
