Topic tags/keywords: design of coping sledrouter table

I plan on building a coping sled for my router table. I have seen designs which use the router table fence or, as an alternative, slots in the router table. I have decided that using slot to orient the sled would be more precise and eliminate errors. I have sprung for the INCRA miter slider and track. It was expensive but will probably work forever. I need suggestions for the distance from the centerline of the router (bit) to the edge of the track. Once this distance is established, I can make progress in designing/ building the coping sled. Thanks for any suggestions.

Are you asking what distance to put the miter slot from the bit? I have seen them at many different distances so I would think that it would depend on the width of the fence on the miter guage. I’m not familiar with the Incra model.

I’ve read another post similar to this one a few weeks ago, and the simple answer is – “It Depends”

It depends mainly on the height of the table top relative to you, and the normal width of the pieces you’ll be putting across the router table.

If you are normally going to run pieces less than 12” wide through, then the track should be 6-10” from the bit. Add a wood fence to your mitre gauge that ends less than 1” from the bit for decent stability.

How far back from the table edge is more important though, as if it is too far back, you’ll always be working half-bent. That is not a good idea.
