Default Adding a slot to a Router table

Hello All,

I purchased a ready made router table with an opening for a router insert. Now all I need to do is to cut the dado for the slot which I will use to attach featherboards and such. Couple of questions for those who have done this kind of thing before:

1. How far away from the router opening should I cut the slot?

2. The table is made with laminate and MDF. Is there anything I should do to try to prevent the laminate from chipping? Would tape over the area to be dadoed help?

I posted this on my other forum and several posters said that adding a slot would weaken the table. Anyone agree?

Any other tips? Thanks

If you're talking about adding a "miter slot", no, this will not weaken the table at all. The depth would need to be equal to the thickness of a miter slot bar which will need to be added.

If your wanting to add feather boards, these can be clamped directed to the table without interference from them quite easily and without adding a miter slot. You can even make a simple fence that allows you to clamp feathers boards to them as well. However, most fences anymore have slots already in them.

I have a slot in my table, and I see no weakness, not sure about the dimension from the bit and the slot (it was in the table top when I bought it)

On cutting the laminate, I have had good luck with lowering the bit to just score the laminate first (no more then a 1/32") then go back and cut my slot into the wood.

Consider the reach your featherboard would have so you are not so far back that it will not reach your piece and also far enough back that it will handle larger pieces if needed.
I agree with jd99 your best bet is to make a very light scoring pass first which will break the surface and make it much less likely to chip on you. Also, after you have finished the dado you should put a slight bevel on the edge of the formica to make it less likely to catch on your tools or work pieces and possibly chip or throw off your cut.

For yrs I used and still do self made feather boards by clamping them to the table. The problem is the size of the boards and that the clamps often get in the way.

A T track slot lets you clamp anywhere along the table or fence and allows for a smaller profile on the boards. I don't know if there is a standard set position but I have my slot centered at 6" from the front of the table and centered 6 5/8" to bit center.

Never bite the hand that looks dirty!
