Adjustable Tongue & Groove Bit

My MLCS set can be used in hand because you are working against a bearing. I have never done it except in a table and I don't think I would want to, but it is possible. The MLCS is completely adjustable and works great. I would bet the Freud is identical.

You lost me about making cuts on your saw. You have tried to cut tongue and grove on your radial arm saw? I can't picture that.

I have the Freud tongue and groove set. I just used it to attach birch edges to a baltic sheet birch for a table.

Both the tongue and groove bits are adjustable for width. The set comes with a number of washers of different thicknesses to acheive this plus a table to help select the correct combination of washers. The groove bit is actually two pieces with teeth that overlap. Placing washers between the two pieces results in a wider groove.

I cut the tongue and grooves with the aid of an improvised router table. I have a Henniker table saw that has plastic-faced extensions on each side. I drilled the necessary holes thru the plastic and suspended the router motor beneath the extension.
