Topic tags/keywords: jig question router

I am new to cope and rail construction and I need a little help. I would like to mention that I am fairly new to this site and am totally impressed by the talent and knowledge out there. Also, the helpfulness that exists is refreshing. I have had a few questions since finding this site and have had great responses. I felt like I was taking and not giving. Finally the other day I was able to respond to someones question on a forum topic.

Back to the question. I purchased a set of Freud adjustable cope and rail bits. I built a coping sled with1/4” hardboard bottom and a pine backerboard. When I set my bit height and run the sled against my router table fence the sled makes contact with the router bit, therefore cutting into the sled bottom. I am thinking that a 1/2” sled bottom may do the trick

Hopefully this is clear to you. Any ideas for the sled would be appreciated.

The pine backer-board should be the only thing hanging over the edge. The sled base should be no closer than the widest part of the bit. The backer should go to the fence. Thickness is not the enemy, it is width.

Rick, it sounds to me like you need to raise your router bit to clear the sled. If you can’t get enough height from your current router set-up, you might want to add a collet extension to your router. Here is one from MLCS and runs about $30.00.

By the way if you have not seen it, Mark Spagnolo produced an informative video, Raising Arizona, that is a pretty good tutorial on making a raised panel door with cope and rail bits.
